For a closed circuit to function, the rebreather must do the exact opposite: remove carbon dioxide from gas and replace the consumed oxygen. Immediately after the gas intake of the gas mass treatment unit, there is an electronically controlled valve (solenoid).\n\nOxygen is added to the loop when this valve opens. After that the gas flows in the space between the canister and the cover of the carbon dioxide scrubber, which is made of finely perforated sheet metal, gas flows through the holes in the sheet metal into the scrubber and proceeds to the centre of the scrubber, where it encounters more perforated sheet metal. Between these two sheet-metal components there are small granules of slaked lime (calcium hydroxide) with a small amount of added sodium hydroxide. The lime reacts with carbon dioxide and removes it from gas with the concurrent formation of limestone.\n\nAfter passing through the filter but before exiting the air-mass treatment unit in the direction of the arrows, gas flows around the sensors. The sensors send information about the amount of oxygen to the control computer, which employs the solenoid to add oxygen so that it is maintained at the required level. Oxygen is added prior to gas reaching the filter for purely practical reasons: if oxygen was added after the filter, a small plume of oxygen would immediately come into contact with the sensors, which would thus show incorrect values.","image":{"mimetype":"image/jpeg","size":77848,"hash":"4731e5b7b2192d1f33f847bf6aa75d691fe7a372","id":"cjt8rgkvm0dts0776kwe3f6jw","filename":"specialcarouserbg.jpg","category":"divesoft/","type":"image"},"isBackgroundBlack":true},{"id":"3","title":"Technicals","subTitle":"AIR-MASS TREATMENT UNIT","description":"The body of the unit is divided into two parts: the head, in which the electronics are housed, and the canister with the chemical filter. The control computers are housed in the upper part of the head. With a rebreather, it generally holds true that the diluent determines the volume of the breathing mixture and oxygen determines its breathability. Air is most commonly used as the diluent for shallower dives and trimix or heliox for deeper ones. Unlike open-circuit diving, priority is given to a mixture with a leaner oxygen content, because oxygen is added from a separate tank. Proper replenishment of oxygen is the main task of the control computers and all electronic and electromagnetic devices in the head. The amount of oxygen – specifically the partial pressure of oxygen in the breathing loop – must be maintained within relatively narrow ranges. This purpose is served by the quartet of ppO2 sensors and two electrically controlled valves (solenoids) for replenishing oxygen. The control computers evaluate data from the sensors and, as needed, open the solenoids, which add oxygen to the loop. Oxygen is transferred to the head via the hose that can be easily seen between the oxygen tank and the canister when the air-mass treatment unit is removed.","image":{"mimetype":"image/jpeg","size":77848,"hash":"4731e5b7b2192d1f33f847bf6aa75d691fe7a372","id":"cjt8rgkvm0dts0776kwe3f6jw","filename":"specialcarouserbg.jpg","category":"divesoft/","type":"image"},"isBackgroundBlack":true},{"id":"4","image":{"mimetype":"image/jpeg","size":77848,"hash":"4731e5b7b2192d1f33f847bf6aa75d691fe7a372","id":"cjt8rgkvm0dts0776kwe3f6jw","filename":"specialcarouserbg.jpg","category":"divesoft/","type":"image"},"title":"Technicals","subTitle":"BACKPLATE, REGULATORS, BCD, BALLAST","description":"All parts of the apparatus, including the attachment straps, are attached to the backplate. The backplate continues downward with the base, which transfers part of the apparatus’s weight to the diver’s lower back, protects the tank valves against damage and serves as a pedestal for standing the apparatus on the ground.\n\nEquipment seen on the back of the Liberty includes the noticeable ballast pouches attached to the tanks. These pouches feature downward-hanging red “rip cords” for emergency jettisoning of the ballast. Firmly attached to the backplate they are the first stages of the regulators (reduction valves), which reduce the high pressure of the gas from the tanks to medium pressure of 8.5 bars relative to the ambient pressure. The gas is then distributed by the hoses to the necessary places in the apparatus.

Each computer has its own battery, two oxygen sensors, a pair of depth and atmospheric pressure sensors, and a helium concentration sensor. Each CU controls a separate electromagnetic valve for adding oxygen to the breathing loop.\n\nThe computers mutually share data from the sensors (each of the computers has access to data from all four oxygen sensors), and mutually synchronize all performed operations, such as decompression calculation. If one of the computers fails, the remaining one has available all necessary devices (oxygen and helium sensors, solenoid) and information (decompression model status) for problem-free continuation of the dive and the diver’s return to the surface.\n\nTwo display units, a head-up display and buddy display are connected to each control unit. The control units can shut down power to the handsets in the event of a malfunction or short (e.g. in the case of cable damage). The handsets do not control the solenoids, nor do they perform decompression calculations. They serve only as the terminal devices of the control units.\n\nThe head-up display (HUD) has three tri-color LEDs and is attached to the DSV in the diver’s field of vision. Blinking LEDs indicate the measured partial pressure of oxygen in the breathing loop as well as danger or malfunctions. The buddy display (BD) on the head of the apparatus notifies the diver’s partner or instructor of critically dangerous levels of the partial pressure of oxygen. The positioning of the HUD and BD are configurable so that you can exchange them or, for example, install two HUDs at the same time.","image":{"mimetype":"image/jpeg","size":77848,"hash":"4731e5b7b2192d1f33f847bf6aa75d691fe7a372","id":"cjt8rgkvm0dts0776kwe3f6jw","filename":"specialcarouserbg.jpg","category":"divesoft/","type":"image"},"isBackgroundBlack":true},{"id":"6","title":"Technicals","subTitle":"DIMENSIONS AND PERFORMANCE","description":"BACKMOUNT\nWeight of the Liberty CCR prepared for diving (without ballast): 36.5 kg (80.5 lb)\nTransport weight (without tanks, without scrubber filling): 23.5 kg (51.8 lb)\nEndurance according to EN 14143:2013 (CO2 production of 1.6 l/min): 2:48 h\nEndurance with CO2 production of 1 l/min (corresponds to increased effort in cold water and at great depth): 4 h\nEndurance with CO2 production of 0.7 l/min (corresponds to moderate effort in favorable conditions): 6 h\nMaximum depth in tests according to EN 14143:2013: 100 m (330 feet)\nMaximum depth with Apeks DST4 1st stages 170 m (557 feet)\nDepth gauge precision test: 350 m (1,150 feet)\nPressure test of all components: 600 m (1,960 feet)\nThe deepest dive we are aware of: 183 m (600 feet)\n\nSIDEMOUNT\nWeight (ready to dive) approx. 21.6 kg (47.6 lb) (regular + stainless), 20.5 kg (45 lb) (shortened + titanium)\nThe total weight is under 23 kg (50.7 lb), when ordered with a Peli Case AIR.

And in many cases, not even multiple malfunctions can cause a complete breakdown.\n\nThe apparatus is designed and programmed so that it is able to cope with any combination of malfunctions as long as at least one control unit and any sensor are still operational. In the case of damage to a cable, the control computer will detect a short in that cable and disconnect the respective handset’s power supply. And if both handsets are lost, the control computers will continue regulating the supply of oxygen according to the most recently selected setpoint. And the Liberty CCR will keep working even if one of the control computers fails. Each computer has its own battery, depth sensor, two oxygen sensors a helium sensor and electrically controlled oxygen supply valve (solenoid).\n\nIn normal circumstances, the two computers communicate with each other and exchange data from the sensors and agree on which of them will add oxygen to the loop. If necessary, either computer can perform this function independently.\n\nLet’s create a catastrophic scenario. We have already lost both handsets, and now one of the computers has shut down. More than half of the electronic systems are inoperable, but the Liberty CCR keeps working. The mechanism for regulating oxygen supply handles this situation with no problems. Could anything else go wrong? Yes, it could. One of the oxygen sensors could malfunction. And not that it would stop sending a signal, as if it had gotten flooded. That would be too simple. The sensor would show “only” an incorrect value and it would appear that the control computer now cannot know which of the sensors to believe. This is a miserable situation. It could fail when you are at one hundred meters below the surface... which, however, would be an advantage. After all, for a hundred-meter dive, you have trimix. The computer is well aware of that, even if you forgot to set the diluent composition before the dive. The built-in helium concentration sensor diligently measures the mixture composition during the dive and stores it in the computer’s memory. Thanks to this, the computer can now calculate the oxygen content based on the measured helium concentration and decide which of the oxygen sensors is in working order. The dive continues. And now it is already clear that even if the last oxygen sensor breaks down, such an event will not put the computer out of action. Based on the last known correct oxygen value, it will switch to indirect measuring of oxygen using the helium sensor and safely continue regulating the supply of oxygen.","isBackgroundBlack":true}],"activeTab":"9"}},"__typename":"ComponentTemplate"},"ComponentTemplate:cjyiek5ng00bz07773k8drspc":{"id":"cjyiek5ng00bz07773k8drspc","name":"Front mounted counterlangs","type":"ProductComponents","content":{"type":"json","json":{"title":"FRONT MOUNTED COUNTERLUNGS CONFIGURATION ","description":"Classic configuration with low profile Dive Surface Valve mouthpiece allows for the best work of breathing (2.6 KJ per liter at 40M) due to proximity of lungs and hydrostatic pressure dynamics.","components":[{"title":"FLOOD TOLERANCY","description":"Front mounted counter lungs configuration most resistant to floods in head and canister","image":{"recommendedSizes":{"width":"130","height":"130"}},"url":"","id":"1"},{"title":"MAVs","description":"Easy accessibility to gas addition valves on counter lungs via LP inflator hose valves.","image":{"recommendedSizes":{"width":"130","height":"130"}},"url":"","id":"2"},{"title":"ADVs","description":"CCR Liberty offers inhouse made spring or diaphhgragm  ADV located on counterlungs inhale side for immediate access to Diluent gas.","image":{"recommendedSizes":{"width":"130","height":"130"}},"url":{"url":"ADVs"},"id":"3"},{"title":"OFFBOARD GAS ACCESIBILITY","description":"All Libery rebreather do offer offboard gas connectivity via free LP ports on 1st stages.

Our primary concern was to build a rebreather system that will enable the diver to safely conduct the dive and will be able to return on the unit. No single malfunction in the electronic system can cause a complete system failure. Unit contains: 4 oxygen sensors, 2 helium sensors, 2 methods of pO2 measuring, 2 independent computers, 2 solenoid valves, 4 displays. Everything is individually sealed. The Liberty rebreather is depth limited at 170m (557ft) due to the use of the Apeks DST4 Environmentally sealed 1st stage regulators. It is recommended that to dive beyond 170M (557ft) the Apeks DST4 1st stages MUST be changed with the Apeks UST4 kit. All components of the Liberty apart from the 1st stages are pressure tested to 600m. In conjunction with the Liberty robust construction the unit also exhibits one of the industry’s best work-of-breathing of rebreathers. The Liberty rebreather has many variations you can choose and configure. The unit can be easily configured for multiple variations; backmount or sidemount, for optimal dive configurations for each dive environment. With a simple conversion kit the user can go from a backmount configuration to a sidemount configuration. Watch our introducing video about Liberty rebreather and its advantages here.","id":"1"},{"question":"Work of breathing?","answer":"Thanks to the careful design of all parts of the breathing loop, the Liberty has extraordinarily low breathing resistance. No off-the-shelf pipe fittings or piping components are used in the Liberty – everything is specially manufactured precisely according to calculations, simulations and test results. Please read our brief articles click here. The Liberty FMCL WOB is 2.16 J/l at 40m, air diluent. And 1.58 J/l at 100m, heliox 10/90.","id":"2"}]}},"__typename":"ComponentTemplate"},"ComponentTemplate:cl06qffhl9ccp0858ja9vdupw":{"id":"cl06qffhl9ccp0858ja9vdupw","name":"hlavička CCR","type":"ProductCrossroadNew","content":{"type":"json","json":{"products":[{"id":"9","url":{"url":"/en/products/ccr-liberty","pageId":"cjv3rpryz00iw0836lc0zx81j"},"title":"CCR Liberty","image":{"mimetype":"image/png","size":806405,"hash":"1ae6594296042204df596da0f33e6591f84da573","id":"ckx3me6k0c5s60776zr3pyct4","filename":"divesoft-ccr-liberty-light-01-1080x1080.png","category":"divesoft/","type":"image"}},{"id":"2","title":"Anatomy","image":{"mimetype":"image/png","size":259316,"hash":"9b3cdb102291f8c95b3a3408e0a493c1bbb94c38","id":"cjxc7r1hw07b20776e7kq8u9o","filename":"sidemount.png","category":"divesoft/","type":"image"},"url":{"url":"/en/products/ccr-liberty/test2-anatomy","pageId":"cl6g9nsgds2c20858pg31ae97"}},{"id":"3","title":"Features","url":{"url":"/en/products/ccr-liberty/test2-features","pageId":"cl6g9opv3s2ck085846otg5l7"},"image":{"mimetype":"image/png","size":111678,"hash":"1b0abc1813359acf3baa47dbc11b4b290aab310c","id":"cl1eybpshr7010776kwxzb09o","filename":"divesoft-liberty-head-01-1080x1080-t.png","category":"divesoft/","type":"image"}},{"id":"5","url":{"url":"https://www.divesoft.com/en/products/ccr-liberty/configurations"},"title":"Configurations","image":{"mimetype":"image/png","size":122646,"hash":"02c52e172aca759e3904acf42d74d7b9b8b67ebe","id":"cl8jv40hdirlg0776njznax3q","filename":"configurations4.png","category":"divesoft/","type":"image"}},{"id":"4","title":"Configurator","url":{"url":"https://www.divesoft.com/ccr-liberty/"},"image":{"mimetype":"image/png","size":6352707,"hash":"25f220967ec22ba2f1feb4223d01dbfd5cc87ed9","id":"cl9mpe0atssnq0776id8dfz3a","filename":"divesoft-liberty-modularity-1920x1080-t.png","category":"divesoft/","type":"image"}}

Our primary concern was to build a rebreather system that will enable the diver to safely conduct the dive and will be able to return on the unit.\n\nNo single malfunction in the electronic system can cause a complete system failure.\n\nUnit contains: 4 oxygen sensors, 2 helium sensors, 2 methods of pO2 measuring, 2 independent computers, 2 solenoid valves, 4 displays. Everything is individually sealed.\n\nThe Liberty rebreather is depth limited at 170m (557ft) due to the use of the Apeks DST4 Env

2ironmentally sealed 1st stage regulators. It is recommended that to dive beyond 170M (557ft) the Apeks DST4 1st stages MUST be changed with the Apeks UST4 kit. All components of the Liberty apart from the 1st stages are pressure tested to 600m. In conjunction with the Liberty robust construction the unit also exhibits one of the industry’s best work-of-breathing of rebreathers.\n\nThe Liberty rebreather has many variations you can choose and configure. The unit can be easily configured for multiple variations; backmount or sidemount, for optimal dive configurations for each dive environment. With a simple conversion kit the user can go from a backmount configuration to a sidemount configuration.\n\nWatch our introducing video about Liberty rebreather and its advantages [here](https://www.youtube.com/watch?v=0sQhlBrMeAw)."},{"id":"2","question":"Work of breathing?","answer":"Thanks to the careful design of all parts of the breathing loop, the Liberty has extraordinarily low breathing resistance. No off-the-shelf pipe fittings or piping components are used in the Liberty – everything is specially manufactured precisely according to calculations, simulations and test results. Please read our brief articles click [here](/en/products/ccr-liberty). The Liberty FMCL WOB is 2.16 J/l at 40m, air diluent. And 1.58 J/l at 100m, heliox 10/90."},{"id":"3","question":"Why two computers?","answer":"Having two computers provides redundancy in the unlikely scenario should there be a failure in one computer, the other computer will be able to completely maintain your decompression schedule and maintain proper PO2 measurement. Other rebreather platforms contain a single computer to which if there was any failure the system will be unable to manage decompression as well as drive solenoids to maintain proper PO2 thus bail-out is necessary.\n\nClick [here](/en/products/ccr-liberty) for control systems article."},{"id":"4","question":"Isn’t Liberty a technical overkill?","answer":"What Divesoft has done with the Liberty is to design a system from the bottom up to properly engineer a rebreather to sufficiently accommodate the requirements to avoid a single component failure. Technical diving demands redundancy and backups. Previously designed rebreather platforms where unable to avoid single part failures either with gas injection with a single solenoid, or single point PO2 monitoring with using only Oxygen cells.\n\nTechnical diving with closed circuit rebreathers can be a strenuous activity but without proper equipment, it can be a dangerous sport. The Liberty rebreather is designed to be fault-tolerant, which means that no single malfunction in the electronic system can cause a catastrophic failure of the whole system rendering the unit to be un-useable.\n\nFor more information click [here](/en/products/ccr-liberty/ccr-liberty-redundancy)."},{"id":"5","question":"Where and by whom is it built?","answer":"The Liberty rebreather is manufactured by Liberty systems, a sister company of Divesoft. The Liberty is built in our state-of-the-art facility in Roudnice nad Labem which is located in the northern part of the Czech Republic, just a few kilometers north of Prague.\n\nClick [here](https://www.youtube.com/watch?v=9mf5YEINadk) for a quick video of our factory."},{"id":"6","question":"What FW/Software/Algorithm is Liberty using?","answer":"We wrote our own software. We are using our own electronics as well. We are using upgraded Bühlmann ZHL-16B algorithm with gradient factors and ceilings. All is built and set in our own, state-of-the-art factory in the Czech Republic.\n\nWe are still growing, and so does the software of Liberty. FW updates are free of charge and you can easily read description of these changes on release notes or download new firmware version [here](/en/products/ccr-liberty/firmaware)."},{"id":"7","question":"What algorithm is Liberty using?","answer":"Bühlmann 16-ZHL/b with gradient factor and ceilings."},{"id":"8","question":"Can I connect my Shearwater?","answer":"No, in order to properly protect the electronics, the two main computers are environmentally sealed, preventing any hook up of external 

2computers such as a Shearwater. Although, non-connected external computers are encouraged to be used as a secondary fixed PPO2 monitoring device.\n"},{"id":"9","question":"Is there any literature referring to Liberty?","answer":"You can see our [manual](/en/products/ccr-liberty/manuals), [YouTube channel](https://www.youtube.com/channel/UCHI2-kHmfoUlAdhQXPKl8lA), [Facebook](https://www.facebook.com/divesoft/), [Configurator](https://ccrliberty.com) or [read references](/en/products/ccr-liberty) from professional divers."},{"id":"10","question":"What about some videos I can check out?","answer":"We have a YouTube channel where users can find videos about diving, tutorials, maintenance and much more..

How should I store them?","answer":"For installing oxygen sensors into Liberty Head watch tutorial our video [here](https://www.youtube.com/watch?v=YOdbaJ6ujaQ).\n\nIf you decide not to use oxygen sensor immediately after purchase. We recommend storing in unopened packaging in a refrigerator, to properly preserve sensor shelf life."},{"id":"8","question":"How to correctly disassemble the unit to let it dry out?","answer":"First, it will be necessary to dry out the water trap after each dive or by the end of the diving day. Begin by detaching the head, then remove the scrubber cartridge, next remove the water trap and dry it with a paper towel. With another paper towel, also dry the exterior surface of the cartridge.\n\nThe head should be left open in order to properly dry and to remove any excess moisture that may have formed on the oxygen and helium sensors. In areas with high humidity, we strongly recommend using the optional DIVESOFT Head drying fan. This ensures the functionality of both types of sensors."},{"id":"9","question":"Why is it necessary to use the drying fan?","answer":"However, the drying fan is only recommended. We find that the Divesoft drying fan can be very effective in removing moisture buildup that can occur on the oxygen sensors during a dive. Removing moisture can significantly reduce any error readings that may occur with a moisture buildup and help preserve the lifespan of the sensor."}

2,{"id":"10","question":"How to store the unit between dive trips?","answer":"It is crucial to always properly clean your unit. When in use, the rebreather’s breathing loop can become a breeding ground for microorganisms from the diver’s respiratory tract and from the external environment. Following proper cleaning procedures can prevent the growth of microorganisms in the warm, humid environment that is your rebreather.\n\nThe purpose of regular cleaning and disinfection is to prevent the multiplication of these microbes to an extent that would pose a hazard to the user and to prevent the transmission of infection between various users.\n\nNot more than a week should be allowed to pass from the first dive after disinfection, until the next disinfection if the CCR Liberty is stored in a cool place. When storing the rebreather at a temperature higher than 25 °C (77 °F), this interval is shortened to four days."},{"id":"11","question":"I won’t be diving for a few months, how should I prepare the unit for long term storage?","answer":"Before storing the rebreather for a period longer than one week, clean and disinfect the unit as usual (see [manual](https://www.divesoft.com/en/products/ccr-liberty/manuals) section 3.5.3 Cleaning and disinfection).\n\nWatch our tutorial video [here](https://www.youtube.com/watch?v=BZNBIynb6No&feature=youtu.be).\n\nIf the CCR Liberty is stored in a dry and clean environment, do not connect the corrugated-hose assembly with the DSV to the head or to the breathing bags and store the rebreather open. Dust occurs even in an environment with the same level of cleanliness as the home environment. Limit accumulation of dust by, for example, covering the unit with a washed cotton bed sheet. Store the detached corrugated hose assembly in a suitable ventilated container that will allow complete drying.\n\nIf you store the CCR Liberty in an environment with a lower degree of cleanliness, store it assembled and closed (without sorbent). Such an environment with a lower degree of cleanliness may be, for example, a home with pets.\n\nBefore putting the closed rebreather in storage, all parts must be thoroughly dried, including all creases in the corrugated hoses and the interior surface of the bags.\n\nCharge the batteries at least once every six months.\n\nIf, after storing the unit for more than a month, you find that moisture persisted inside the apparatus or you can smell mustiness or mold from the corrugated hoses, it is necessary to disinfect the apparatus again. When storing the rebreather, make sure that no rubber parts (hoses, cables) are pinched or compressed.\n\nEnsure that no other objects are leaned against the rebreather. Secure the rebreather against falling."},{"id":"12","question":"Is there a way how to seal the scrubber canister, to protect the sorbent?","answer":"Yes, we recommend using the DIVESOFT \"[Scrubber cover with stickers](http://eshop.divesoft.eu/cz/1269-scrubber-cover-with-stickers/7167)\". It is advisable to write the date of the first filling and the times of the individual dives on which the scrubber was used. After changing the sorbent, change the label.\n\nDo not store used and closed scrubber for more than 30 days after first use."}],"activeTab":"4"},"id":"#31","type":"component","lock":false,"position":18},{"name":"LinkAnchor","data":{"anchorId":"ccr-liberty-troubleshooting"},"id":"#54","type":"component","lock":false,"position":19},{"name":"FaqNew","data":{"backgroundColor":"#ffffff","title":"Troubleshooting","subtitle":"CCR Liberty Rebreather","showBreadcrumbs":false,"hideHeader":false,"questions":[{"id":"1","question":"What do I do if the unit floods?","answer":"The probability of the unit to flood significantly is very low if proper procedures are followed. After carefully assembling the apparatus and performing the prescribed pre-dive procedures, flooding can be ruled out unless there is a major disruption of the breathing loop’s integrity due to mechanical damage. In the event of significant flooding, it is necessary to immediately switch to the bailout breathing apparatus and to use the compensator (BCD) to prevent loss of buoyancy.\n\nDo not inhale from the loop if the mixture from the rebreather’s DSV contains fluid. In extreme cases, this could contain a so-called caustic cocktail, i.e. a caustic mixture with dissolved lye from the sorbent.\n\nA smaller amount of water can enter the loop through an open DSV when the mouthpiece falls out of the diver’s mouth. In such a case, water enters into the exhalation bag. Though this does not represent an catastrophic emergency, it is advisable to expel water from the exhalation bag via the overpressure valve as soon as the opportunity arises. Open the overpressure valve completely. Be sure to stabilize your buoyancy in order to avoid a significant loss of buoyancy control. Add diluent to the circuit with the manual bypass valve and perform a diluent flush. Assume a position that brings the overpressure valve to the lowest point of the exhalation bag. Expel the water from the bag by exhaling and pressing on the bag with your hand. This skill will be taught to you by your instructor and it is important to be adequately performed with routine practice."},{"id":"2","question":"My Helium sensor won’t calibrate?","answer":"If you try to calibrate Helium sensor with any success, please try to dry the helium sensors out. Helium sensors are sensitive for moisture condensation. The moisture condenses directly inside the sensor; neither perfect drying of Liberty head does not remove the condensate from the parts inside of the sensors. When the Helium sensor shows Error or not calibrated, it probably needs maintenance.\n\nFor the maintenance you will require a 3mm Hex key.\n\nProcedure:\n\n1. Disconnect the power by removing battery jumpers.\n1. Remove oxygen cells block by removing 2 screws and pulling out. No component should require excessive force ever!\n1. Remove helium sensors by removing screw and proceed to pull by two finger grip.\n1. Suck the condensate from both 

2sides using mouth. Never blow into the sensor by mouth or any tools. This could cause even the smallest overpressure of air flow to damage the sensitive membrane inside the sensor. This damage will void any warranty and is not covered. Once moisture is sucked out then leave sensors to dry out in dry, warm place.\n1. Once sensors have been left to dry, reinstall to compartment and tighten screws.\n1. Re-insert oxygen sell block and tighten both screws.\n1. Turn on unit power by inserting jumpers to batteries.\n1. Proceed to calibrate helium sensors (Surface mode main menu/Setup/Calibration/Calibrate He-air).\n\nWatch our tutorial video [here](https://www.youtube.com/watch?v=DUWGQXZPL78).\n"},{"id":"3","question":"Handset/Buddy/Head up display flooded?","answer":"In this scenario, you should send the flooded handset/buddy/HUD to a Liberty authorized service technician or directly to our factory.

First, please check the charger and its functionality.\n\nIf the charger is working correctly, please change the batteries by switching their locations on the unit head. This will check whether the battery is defective on the other half of the Head. If you find out that the battery is misfunction, please replace it.\n\nIf you find out that the problem is not on side of the battery, problem is probably concerning of handset or control unit. Then please check the functionality of the handsets. Follow the same procedure as with the batteries to check connection. Change them and connect them to unit head.\n\nPlease note that service of handsets or control units are provided by Liberty authorized service technician or directly at our factory.

Please watch our video [here](https://www.youtube.com/watch?v=XSu-OAqSkNE&feature=youtu.be)."},{"id":"2","question":"How to pack my unit for transportation?","answer":"Very often we separate the head from the unit and place the head in a carry-on bag and the rest of the unit should be in a checked-in luggage. A majority of our instructors recommend using the Pelican Air 1615 Case for air travel. Please do not transport it in standby mode. Batteries must be disconnected by removing or turning the battery jumpers."},{"id":"3","question":"Do I need to bleed the cylinders?","answer":"Yes! Airline regulations require that all transported pressure cylinders must be empty with valves removed. Place the valves in clean PE bags (Ziploc) and place tape over the neck to prevent contamination. It is possible that security personnel will want to look inside the cylinders. Therefore it is not appropriate to use tight plugs that cannot be removed without tools."},{"id":"4","question":"Can I have my rebreather as carry on?","answer":"Most airlines restrict carry-on baggage weight. We recommend to separate Liberty Head and transport it in the hand luggage. You will significantly reduce the weight of your luggage and moreover you will protect the most sensitive part of your device."},{"id":"5","question":"How should I behave going through security with my rebreather?","answer":"Most airline personnel and security staff do not know what technical diving equipment is, or rebreathers. It can be very helpful to travel with appropriate documentation such as the Liberty manual or the manufacturers shipping checklist but be sure to always remain very calm and most importantly to allocate at least double the time it would normally take to travel through security so as to remove any stress as this process can take a while."}],"activeTab":"3"},"id":"#33","type":"component","lock":false,"position":22},{"name":"LinkAnchor","data":{"anchorId":"analyzers-frequent-questions"},"id":"#56","type":"component","lock":false,"position":23},{"name":"FaqNew","data":{"backgroundColor":"#ffffff","title":"Frequent Questions","subtitle":"Analyzers","showBreadcrumbs":false,"hideHeader":false,"questions":[{"id":"1","question":"How long is the oxygen sensor's service life?","answer":"An electrochemical sensor is used for measuring the oxygen content. When measuring (and even storing the sensor in air), a chemical reaction occurs in the sensor. The sensor's service life is is determined by the depletion of the reagent. The expected service life of the sensor is three years when stored in air at normal temperature with 50% humidity. It is necessary to replace the sensor upon expiration of its service life."},{"id":"2","question":"How long is the helium sensor's service life?","answer":"The helium content is determined using a physical method which in causes no wear and tear in the sensor. Therefore, the sensor's service life is, in principle, unlimited."},{"id":"3","question":"Is it possible to measure other gases with the analyzer?","answer":"Firmware versions prior to 2.19: No. The analyzer is intended only for mixtures containing air (more precisely, nitrogen with characteristic presence of atmospheric argon), oxygen and helium. The presense of another gas (e.g., a larger amount of CO2) in the mixture causes unreliable results. Under certain conditions, the analyzer can be modified for mixtures containing other gases. More information about the possibilities of modification and calibration can be obtained from the manufacturer.\n\nFirware versions 2.19 and later have special \"Gas purity\" mode, which can measure any binary gas mixture, if sound velicities in each component are different enough. You have to define physical parameters of each component (both specific heats Cp and Cv and molar mass). If fact, a component can be a mixture, but each must contain different gases. Default setting measures Ar and air."},{"id":"4","question":"Can the analyzer identify trace amounts of helium?","answer":"The analyzer measures with differentiation on the order of tenths of a percent. Thus, helium in a concentration smaller than the analyzer's differentiation cannot be identified."},{"id":"5","question":"Why does the analyzer show that there is -0.3% helium in air?","answer":"Of course, the correct value would be zero. However, measuring is hampered by unavoidable discrepancies on the order of tenths of a percent. As such discrepancies can be positive or negative, it therefore can happen that the analyzer shows -0.3 % or 0.3 % helium in air, just as 99.7 % or 100.3 % may be displayed when measuring pure helium.\n\nSimilar situation is with measuring of oxygen. Possible error is up to 1 % (depending on manufacturer of O2 cell).\n\nValues are displayed as calculated, there are no hidden altering of measured data to make values look better."},{"id":"6","question":"I upgraded the firmware and He sensor stopped working","answer":"In older firmware revisions the measuring click was hard coded to 30us. Starting with revision 2.18, the click duration is adjustable in range 10-250us. If the stored value was less than 30, the measuring click is not strong enough to be detected.

I love the quiet illusion of zero gravity, the sense of entering new worlds, and the energy that comes from teaching, watching curiosity spark in students and sharing discoveries with friends. My diving life is a collection of moments that stay with me: exploring a sunken Jewish cemetery, diving to forty meters on the Barbakonac wall with minimal gear when I was thirteen, or spending days preparing to push further into the Manajama cave on Brač. These aren’t isolated memories; they’re part of a continuous journey.\n\nI was among the first divers to use bailout rebreathers and became the world’s first official bailout rebreather instructor. Today, I’m also the only Factory Instructor Trainer for all Liberty configurations. Diving isn’t just part of my life, it’s the framework that shapes it. It’s where I’ve learned the most and where I’ve given the most back.\n\nMy Divesoft story started simply by being in the right place at the right time.\nOutside the water, I reset through cycling, walking my dog, or getting lost in a good book or film.\n","contact":"","images":[{"id":"1","image":{"mimetype":"image/jpeg","size":917715,"hash":"62ce883c95579293df367d039df8cae78544b5fa","id":"cmlgg4slelmqv080098ouz74r","filename":"simanek.jpg","category":"divesoft/","type":"image","alt":"photo of Jakub Šimánek, CCR Liberty Factory Instructor Trainer from Divesoft"}},{"id":"2","image":{"mimetype":"image/jpeg","size":830816,"hash":"51c3c1993bc8b0ad63054ed7fa1178c6c3437814","id":"cmegvwsmt9cdz085059w6xtid","filename":"jakub-simanek-factory-trainer-divesoft-02.jpg","category":"divesoft/","type":"image","alt":"photo of Jakub Šimánek, CCR Liberty Factory Instructor Trainer from Divesoft"}},{"id":"3","image":{"mimetype":"image/jpeg","size":944549,"hash":"d1a67197b2b80b8c3bffb2641b2b6ac48ef6d33c","id":"cmegvx7hx9cey0850rxkbwweu","filename":"jakub-simanek-factory-trainer-divesoft-03.jpg","category":"divesoft/","type":"image","alt":"photo of Jakub Šimánek, CCR Liberty Factory Instructor Trainer from Divesoft"}}],"articles":[],"equipment":[{"id":"1","title":"LIBERTY <light>SIDEMOUNT</light>","eshopUrl":{"url":"/en/products/ccr-liberty/ccr-liberty-sidemount","pageId":"cjyztusbt039t0777kqbo8xj8"},"image":{"mimetype":"image/png","size":4865897,"hash":"3fe48965007b02902957171dfa580f170ee527f5","id":"cmll0z8ylnntr08006hyn71y2","filename":"liberty-sidemount.png","category":"divesoft/","type":"image","alt":"Liberty Sidemount"}},{"id":"2","title":"DNA ANALYZER","eshopUrl":{"url":"/en/products/analyzers/dna","pageId":"clf9rs5c3ltkw0835vujrrtxu"},"image":{"mimetype":"image/png","size":3394952,"hash":"3d3b683198cb610681a0101ad3399882a47022ff","id":"cmll0zjvknnu10800qvuoq4yf","filename":"dna.png","category":"divesoft/","type":"image","alt":"DNA Analyzer"}},{"id":"4","title":"LIBERTY <light>BACKMOUNT</light>","eshopUrl":{"url":"/en/products/ccr-liberty/ccr-liberty-bmcl-fmcl","pageId":"ckt0i4dg51ogp0988dpgn8lwr"},"image":{"mimetype":"image/png","size":4767263,"hash":"e2de98edb74cb17d7d0a9747ed71b444560fab81","id":"cmll10106nnub0800d3rxvp46","filename":"liberty-backmount.png","category":"divesoft/","type":"image","alt":"Liberty Backmount"}}],"activeTab":"1"},"id":"#9","type":"component","lock":false,"position":1},{"name":"JsonLD","data":{"jsonLD":"{\n  \"@context\": \"https://schema.org/\",\n  \"@type\": \"Person\",\n  \"@id\": \"https://www.divesoft.com/en/about-us/jakub-simanek#person\",\n  \"name\": \"Jakub Šimánek\",\n  \"givenName\": \"Jakub\",\n  \"familyName\": \"Šimánek\",\n  \"jobTitle\": \"CCR Liberty Factory Instructor Trainer\",\n  \"knowsAbout\": [\n    \"CCR Liberty Factory Instructor Training\",\n    \"Liberty Sidemount Factory Instructor Training\",\n    \"CCR Liberty Hypoxic Trimix\",\n    \"Liberty Sidemount Hypoxic Trimix\",\n    \"Bailout/Dual CCR diving\"\n  ],\n  \"worksFor\": {\n    \"@type\": \"Organization\",\n    \"@id\": \"https://www.divesoft.com/#organization\",\n    \"name\": \"Divesoft\",\n    \"url\": \"https://www.divesoft.com/\",\n    \"logo\": \"https://www.divesoft.com/assets/divesoft/images/logo.svg\"\n  },\n  \"url\": \"https://www.divesoft.com/en/about-us/jakub-simanek\",\n  \"image\": \"http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/62ce883c95579293df367d039df8cae78544b5fa_simanek.jpg\",\n  \"description\": \"Jakub Šimánek is a Divesoft test diver and instructor trainer for the CCR Liberty.

Therefore, the gas composition shown by the analyzer does not mean by itself that the real composition of the mix is equal to the displayed values. The displayed mix composition is invalid unless the mixing technology ensures that there are no other gases present in the mix except air/nitrogen, pure oxygen and pure helium.  \n\nThe analyzer is not a certified measuring instrument. The results of measuring are only informative and it is not possible to use such results where a certified measuring instrument is required.  \n\nWhen analyzing mixes in situations where the incorrect composition of the mixes could cause material damage, injury to health or threaten human health or life, for example in the case of breathing mixes for diving, the results of the analysis may not be used as confirmation of the correct mix composition. In these cases, the analyzer can only be used as an aid for increasing the probability that such incorrect mix composition will be detected before its use. The correctness of the mix composition must be established by the technology used to prepare it.  \n\nThe correct preparation of breathing mixes for diving (nitrox – oxygen-enriched air, trimix – a mixture of air, oxygen and helium, heliox – a mixture of oxygen and helium) requires special knowledge and experience which is possible to gain, for example, through an appropriate course. A failure to apply such knowledge can lead to an incorrect mix, even though the results of the analysis are seemingly correct. Such a situation can also be the result of a failure to take into account the influence of temperature and compressibility, an insufficient blending of the mix and other factors.  \n\nPlease remember that the analyzer can be broken or damaged and that the oxygen sensor is by its nature subject to ageing and thus its properties deteriorate.  \n\nTherefore always verify the measured data in another way, such as by precise preparation of the mix, another analytical method, etc. In addition, the measured value must be subject to critical assessment using a common-sense approach and if it differs from the allowable variation of mixing accuracy, it must be considered invali

Measuring principle**  \n\nThe described measuring principle is valid only for mixes of air, oxygen and helium.  \n\nAn electrochemical sensor is used to determine the oxygen content. The voltage at the sensor’s output is proportional to the oxygen content in the analyzed mix. The sensor has a limited service life and the proportionality of the dependence of voltage on the oxygen content changes over time; therefore, it has to be regularly calibrated. It is possible to choose between single-point, two-point and three-point calibration. Single-point calibration is fast, especially if air is chosen as the calibrating mix. For greater accuracy of the measurement, two-point calibration is used with two different mixes, typically air and pure oxygen. For strongly hypoxic mixes, i.e. mixes containing less than approximately 15% oxygen, three-point calibration is recommended. In this case, the third calibration gas should be a gas with zero oxygen content, i.e. pure helium or argon.  \n\nHelium content is determined on the basis of measuring the speed of sound in the analyzed mix. The speed of sound depends on the content of helium and oxygen, and the temperature of the mix. The dependence of the speed of sound on pressure is small and can be disregarded under normal atmospheric pressure.  \n\nAt 0º C the speed of sound is approximately 970 m/s in pure helium, 330 m/s in air and 315 m/s in pure oxygen. Raising the temperature by one degree increases the speed of sound by 0.175 %. The speed of sound in the mix is described by a non-linear function of temperature, oxygen content and helium content.  \n\nThe content of helium is determined by measuring the speed of sound, temperature of the mix and the content of oxygen. When measuring the concentration of helium, it is therefore necessary to have the oxygen sensor correctly calibrated or to know the oxygen content and enter it into the instrument.  \n\nThe speed of sound is measured directly as the time it takes for an acoustic impulse to travel between two microphones. This measurement is performed alternately in both directions to make it possible to eliminate the influence of the gas flow-rate in the probe on the calculation. The acoustic impulses are heard as weak “clicks” from the probe in the helium-measuring mode.  \n\nGas is delivered to the analyzer from a sampler connected to the compressed-gas tank and the gas flow is controlled using a nozzle to provide the volume needed for the analysis.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#55","type":"component","lock":false,"position":17},{"name":"Divider","data":{"color":"darkGray"},"id":"#58","type":"component","lock":false,"position":18},{"name":"SectionDivider","data":{"title":"03.

This means that the result is interim, with lower accuracy. When the brackets disappear, the accuracy of the result is final.  \n\nIn case of a measuring error, for instance at a pneumatic shock in the inlet hose, the value of the measured helium concentration disappears for the time of duration of the error state.  \n\nThe well-arranged format shows the composition in a way used by divers to call the mixtures:  \n—\tAir: air with the oxygen content between 20.5 % and 21.5 %.  \n—\tEAN, for instance EAN 36, is air enriched with oxygen, in this case up to 36 % oxygen.  \n—\tTMX, for instance TMX 18/45, is trimix or the mixture of air, oxygen and helium, in this particular case containing 18 % oxygen and 45 % helium.  \n—\tHeliox, for instance Heliox 16 % O2, is a mixture of oxygen and helium.  \n—\tFoul Air, for instance Foul Air (10 % O2), is foul or vitiated air with a reduced oxygen content.

We recommend that such calibration be performed at least once a month. Analyzer with the older version than 2.4, the calibration is always necessary when changing altitude. Version 2.4 has a built-in barometer sensor, which corrects itself. If you require the most precise results, calibrate the sensor before each measuring.  \n\nCalibration of the sensor is performed as either single-point or two-point or three-point. During single-point calibration, the content of oxygen in air, which is known and constant (20.95 %), is measured by the sensor. The calibration constant of the sensor is set so that the instrument displays 21.0 % (after rounding).  \n\nTwo-point calibration proceeds in the same manner as single-point calibration, but uses two calibration gases – pure oxygen and air. Two-point calibration is more arduous as it requires the use of oxygen. However, it provides more precise results during measuring.  \n\nThee-point calibration is recommended for measuring hypoxic mixes, containing less than approximately 15 % oxygen. In this case, the third calibration gas should be a gas with zero oxygen content, i.e. pure helium or argon.  \n\nCalibration of the oxygen sensor is started by pressing the CAL key at any time during the measuring.  \n\nAs the first step of calibration, we must choose between single-point, two-point or three-point calibration using the **| ˄ |** and **| ˅ |** keys and confirm the selection using the **| OK |** key.  \n\nIt is then necessary to choose the oxygen content in the calibration mixture.  \n\nThe oxygen content is adjusted by tenths of a percent by pressing the **| ˄ |** key (to increase the content) or the **| ˅ |** key (to decrease the content). Use the **| MODE |** key to choose whether to make adjustments by tenths, whole units, or units of ten percentage points. Upon setting the desired values, confirm the data using the **| OK |** key.  \n\nFor quickly setting typical values when setting the oxygen content it is possible to use the CAL key, which sets the oxygen content at 21 % in the case of the first calibration point or 100 % at the second point and 0 % at the third point.  \n\nUpon setting and confirming the calibration of gases, calibration of the sensor begins. The current calibration point, sensor voltage in millivolts and the temperature of the gas appear on the display.  \n\nAfter the temperature and voltage have stabilized (however, at least after ten seconds), the STABLE prompt appears, which means that it is possible to confirm the performed calibration using the **| OK |** key. If the measured values change before the **| OK |** key is pressed, the STABLE sign disappears and calibration proceeds until further steady values are attained.

Therefore, the gas composition shown by the analyzer does not mean by itself that the real composition of the mix is equal to the displayed values. The displayed mix composition is invalid unless the mixing technology ensures that there are no other gases present in the mix except air/nitrogen, pure oxygen and pure helium.  \n\nThe analyzer is not a certified measuring instrument. The results of measuring are only informative and it is not possible to use such results where a certified measuring instrument is required.  \n\nWhen analyzing mixes in situations where the incorrect composition of the mixes could cause material damage, injury to health or threaten human health or life, for example in the case of breathing mixes for diving, the results of the analysis may not be used as confirmation of the correct mix composition. In these cases, the analyzer can only be used as an aid for increasing the probability that such incorrect mix composition will be detected before its use. The correctness of the mix composition must be established by the technology used to prepare it.  \n\nThe correct preparation of breathing mixes for diving (nitrox – oxygen-enriched air, trimix – a mixture of air, oxygen and helium, heliox – a mixture of oxygen and helium) requires special knowledge and experience which is possible to gain, for example, through an appropriate course. A failure to apply such knowledge can lead to an incorrect mix, even though the results of the analysis are seemingly correct. Such a situation can also be the result of a failure to take into account the influence of temperature and compressibility, an insufficient blending of the mix and other factors.  \n\nPlease remember that the analyzer can be broken or damaged and that the oxygen sensor is by its nature subject to ageing and thus its properties deteriorate.  \n\nTherefore always verify the measured data in another way, such as by precise preparation of the mix, another analytical method, etc. In addition, the measured value must be subject to critical assessment using a common-sense approach and if it differs from the allowable variation of mixing accuracy, it must be considered invali

Measuring principle**\n\nThe described measuring principle is valid only for mixes of air, oxygen and helium.  \n\nAn electrochemical sensor is used to determine the oxygen content. The voltage at the sensor’s output is proportional to the oxygen content in the analyzed mix. The sensor has a limited service life and the proportionality of the dependence of voltage on the oxygen content changes over time; therefore, it has to be regularly calibrated. It is possible to choose between single-point, two-point and three-point calibration. Single-point calibration is fast, especially if air is chosen as the calibrating mix. For greater accuracy of the measurement, two-point calibration is used with two different mixes, typically air and pure oxygen. For strongly hypoxic mixes, i.e. mixes containing less than approximately 15% oxygen, three-point calibration is recommended. In this case, the third calibration gas should be a gas with zero oxygen content, i.e. pure helium or argon.  \n\nHelium content is determined on the basis of measuring the speed of sound in the analyzed mix. The speed of sound depends on the content of helium and oxygen, and the temperature of the mix. The dependence of the speed of sound on pressure is small and can be disregarded under normal atmospheric pressure.  \n\nAt 0º C the speed of sound is approximately 970 m/s in pure helium, 330 m/s in air and 315 m/s in pure oxygen. Raising the temperature by one degree increases the speed of sound by 0.175 %. The speed of sound in the mix is described by a non-linear function of temperature, oxygen content and helium content.  \n\nThe content of helium is determined by measuring the speed of sound, temperature of the mix and the content of oxygen. When measuring the concentration of helium, it is therefore necessary to have the oxygen sensor correctly calibrated or to know the oxygen content and enter it into the instrument.  \n\nThe speed of sound is measured directly as the time it takes for an acoustic impulse to travel between two microphones. This measurement is performed alternately in both directions to make it possible to eliminate the influence of the gas flow-rate in the probe on the calculation. The acoustic impulses are heard as weak “clicks” from the probe in the helium-measuring mode.  \n\nGas is delivered to the analyzer from a sampler connected to the compressed-gas tank and the gas flow is controlled using a nozzle to provide the volume needed for the analysis.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#54","type":"component","lock":false,"position":14},{"name":"Divider","data":{"color":"darkGray"},"id":"#55","type":"component","lock":false,"position":15}

Calibration of the oxygen sensor**\n\nThe oxygen sensor’s properties change over time and it is therefore necessary to recalibrate it We recommend that such calibration be performed at least once a month The analyzer is equipped with built-in barometer sensor, which compensates for changes in altitude while traveling to dive sites.  \n\nCalibration of the sensor is performed as either single-point or two-point or three-point. During single-point calibration, the content of oxygen in air, which is known and constant (20.95 %), is measured by the sensor. The calibration constant of the sensor is set so that the instrument displays 21.0 % (after rounding).  \n\nTwo-point calibration proceeds in the same manner as single-point calibration, but uses two calibration gases – pure oxygen and air. Two-point calibration is more arduous as it requires the use of oxygen. However, it provides more precise results during measuring.  \n\nThee-point calibration is recommended for measuring hypoxic mixes, containing less than approximately 15 % oxygen. In this case, the third calibration gas should be a gas with zero oxygen content, i.e. pure helium or argon.  \n\nCalibration of the oxygen sensor is started by pressing the **| CAL |** key at any time during the measuring.  \n\nAs the first step of calibration, we must choose between single-point, two-point or three-point calibration using the **| ˄ |** and **| ˅ |** keys and confirm the selection using the **| OK |** key.  \n\nIt is then necessary to choose the oxygen content in the calibration mixture.  \n\nThe oxygen content is adjusted by tenths of a percent by pressing the **| ˄ |** key (to increase the content) or the **| ˅ |** key (to decrease the content). Use the **| MODE |** key to choose whether to make adjustments by tenths, whole units, or units of ten percentage points. Upon setting the desired values, confirm the data using the **| OK |** key.  \n\nFor quickly setting typical values when setting the oxygen content it is possible to use the CAL key, which sets the oxygen content at 21 % in the case of the first calibration point or 100 % at the second point and 0 % at the third point.  \n\nUpon setting and confirming the calibration of gases, calibration of the sensor begins. The current calibration point, sensor voltage in millivolts and the temperature of the gas appear on the display.  \n\nAfter the temperature and voltage have stabilized (however, at least after ten seconds), the STABLE prompt appears, which means that it is possible to confirm the performed calibration using the **| OK |** key.

The gases are displayed in the following order: the remaining gas in the bottle, added mix 1–3, the required mix. For each mix, the composition, volume of the bottle (the actual, “water” volume of the bottle is specified) and gas pressure in the bottle are specified. If the volume of the gas is unlimited (for instance, if supplied by a compressor at a constant pressure), enter the bottle volume as zero.

Nelze jej použít pro analýzu směsí obsahujících jiné plyny, tedy například ani pro směsi připravené z jiných než čistých plynů nebo směsí, ve kterých je vzduch nahrazen čistým dusíkem (bez vzdušného argonu).  \n\nFyzikální a chemický princip použitých čidel nezaručuje, že čidla budou selektivně citlivá na konkrétní plyn (kyslík, helium), ale existuje celá řada plynů, na které čidla reagují. Složení plynu ukázané analyzátorem proto samo o sobě ještě neznamená, že by skutečné složení směsi bylo shodné se zobrazeným údajem.Zobrazené složení směsi je neplatné pokud zároveň technologie míchání směsi nezaručuje, že ve směsi nejsou jiné plyny než vzduch, čistý kyslík a čisté helium.  \n\nAnalyzátor není úředně ověřené měřidlo. Výsledky měření jsou pouze informativní a není je možné použít tam, kde je požadováno úřední ověření měřidla.  \n\nPři analýze směsí v případech, kdy by nesprávné složení směsi mohlo způsobit hmotnou škodu, újmu na zdraví nebo ohrožení zdraví nebo života, tedy například v případě dýchacích směsí pro potápění, se nesmí výsledek analýzy považovat za potvrzení správného složení směsi. V těchto případech lze analyzátor použít pouze jako pomůcku pro zvýšení pravděpodobnosti, že bude zjištěno nesprávné složení směsi před jejím použitím.Správnost složení směsi musí být dána technologií její přípravy.  \n\nSprávná příprava dýchacích směsí pro potápění (nitrox – vzduch obohacený kyslíkem, trimix – směs vzduchu, kyslíku a helia, heliox – směs kyslíku a helia) vyžaduje zvláštní znalosti a zkušenosti, které je možné získat například ve vhodném kursu.Bez aplikace těchto znalostí může dojít k přípravě nesprávné směsi i přes zdánlivě správný výsledek analýzy.K takové situaci může dojít mimo jiné zanedbáním vlivu teploty a kompresibility, nedostatečným promícháním směsi a dalšími faktory.  \n\nMějte na paměti, že analyzátor se může porouchat či být poškozen a že kyslíkové čidlo z principu podléhá stárnutí, čímž dochází ke zhoršování jeho vlastností.Naměřený údaj proto vždy ověřte ještě jiným způsobem, jako je zaručená precizní příprava směsi, jiná analytická metoda a podobně.Naměřený údaj musí být též kriticky posouzen zdravým rozumem a pokud se liší od očekávatelné tolerance přesnosti míchání, musí být považován za nesprávný.

Princip funkce**\n\nPopsaný princip měření platí pouze pro směsi vzduchu, kyslíku a helia.  \n\nPro stanovení obsahu kyslíku je použit elektrochemický sensor. Napětí na výstupu senzoru je úměrné obsahu kyslíku v analyzované směsi. Senzor má omezenou životnost a úměrnost závislosti napětí na obsahu kyslíku se během doby mění, proto je nutné jej pravidelně kaliborovat. Lze zvolit mezi jednobodovou, dvoubodovou nebo tříbodovou kalibrací. Jednobodová kalibrace je rychlá, zejména pokud se jako kalibrační směs zvolí vzduch. Pro vyšší přesnost měření se používá dvoubodová kalibrace se dvěma různými se směsmi, zpravidla vzduchem a čistým kyslíkem. Pro výrazně hypoxické směsi, tj.směsi obsahující méně než asi 15 % kyslíku se doporučuje použít tříbodovou kalibraci. Jako třetí plyn pro kalibraci má být v tomto případě použit plyn s nulovým obsahem kyslíku, tedy čisté helium případně argon.\n\nObsah helia se stanovuje na základě měření rychlosti zvuku v analyzované směsi. Rychlost zvuku závisí na obsahu helia, kyslíku a na teplotě směsi. Závislost rychlosti zvuku na tlaku je malá a v okolí normálního atmosférického tlaku ji lze zanedbat.\n\nPři teplotě 0°C je rychlost zvuku přibližně 970 m/s v čistém heliu, 330 m/s ve vzduchu a 315 m/s v čistém kyslíku. Zvýšením teploty o jeden stupeň se rychlost zvuku zvýší přibližně o 0.175 %. Rychlost zvuku ve směsi je popsána nelineární funkcí teploty, obsahu kyslíku a obsahu helia.\n\nObsah helia se určuje z naměřené rychlosti zvuku, teploty směsi a obsahu kyslíku. Při měření koncentrace helia je proto důležité mít správně kalibrovaný kyslíkový senzor nebo znát obsah kyslíku a zadat jej do přístroje.\n\nRychlost zvuku se měří přímo jako časový rozdíl mezi přijetím akustického impulsu dvěma mikrofony. Měří se střídavě v obou směrech, aby bylo možné výpočtem eliminovat proudění plynu v sondě. Akustické impulsy jsou slyÅ¡et jako slabé cvakání v režimu měření helia.\n\nPlyn se do analyzátoru přivádí z omezovače průtoku, který je připojen na lahev se stlačeným plynem a pomocí trysky omezuje průtok odebíraného plynu na množství potřebné pro analýzu.\n","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#56","type":"component","lock":false,"position":17},{"name":"Divider","data":{"color":"darkGray"},"id":"#57","type":"component","lock":false,"position":18},{"name":"SectionDivider","data":{"title":"03.

Pokud požadujete co nejpřesnější výsledky, kalibrujte čidlo před každým měřením.  \n\nKalibrace čidla se provádí jedno– až tříbodová. Při jednobodové kalibraci se čidlem změří obsah kyslíku ve vzduchu, který

Dvoubodová kalibrace je pracnější, vyžaduje použití kyslíku, ale dává přesnější výsledky při měření.  \n\nTříbodová kalibrace se doporučuje použít pro měření hypoxických směsí obsahujících méně než asi 15 % kyslíku. Jako třetí plyn pro kalibraci má být v tomto případě použita přesná kalibrační směs s obsahem kyslíku blízkým připravované směsi. Pro měření velmi nízkého obsah kyslíku lze tuto kalibrační směs nahradit plynem s nulovým obsahem kyslíku, tedy čistým heliem případně argonem.  \n\nKalibraci kyslíkového senzoru spustíte stisknutím tlačítka **| CAL |** kdykoliv během měření.  \n\nJako první krok kalibrace zvolte mezi jednobodovou (1B), dvoubodovou (2B) nebo tříbodovou (3B) kalibrací pomocí tlačítek **| ˄ |** a **| ˅ |** a potvrzením výběru tlačítkem **| OK |**.  \n\nPoté zvolte obsah kyslíku v kalibračních směsích.  \n\nObsah kyslíku se nastavuje po desetinách procenta stisknutím tlačítka **| ˄ |** (zvýšení obsahu) a nebo **| ˅ |** (snížení obsahu).

Brett is a director of [Kast Underwater Research](https://sites.google.com/view/karstunderwater/home) and has pushed the limits in exploration utilizing rebreathers as primary and bailout systems.\n\nTo begin the conversation, Joe kicks off with defining **what Bailout or Dual CCR systems are**, how we should describe them with their application vs. environment. They continue the conversation with the secondary or \"back up\" rebreather issues, whether the rebreather should have an integrated open circuit system or not, its usage with different scenarios during the rebreather failure, also covering various types of diving environment. They also discuss the evolution of the rebreather over the years based on their own experience, the [BOV built-in mouthpiece](https://www.divesoft.com/en/products/bovdsvadv) or two separate systems, and the task loading when using the BOV system and more.   \n\nBefore the end of this episode, Joe is curious about the logistical issues combining different systems, such as **manual primary vs backup electronic systems** or vice versa. \n\nTo learn more about the Bail Out CCR, click to watch it now! 🔻\n\nSee also [Bailout CCR Series #3 focused on dual and bailout rebreathers training](https://www.divesoft.com/en/blog/mark-powell-edoardo-pavia-and-paul-toomer-dual-and-bailout-rebreathers-training).","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":989942,"hash":"c6a0b8cfa1f0eebf30d4d856e0b883f58b6bd03b","id":"cksnc01mmo50e0776gr7q2716","filename":"11-blog-ccr-bailout.png","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"GalleryAndVideo","data":{"title":"Bailout CCR Series #1 | Jakub Šimánek, Steve Bogaerts and Brett Hemphill","video":{"type":"embeddedVideo","url":"https://www.youtube.com/embed/n9cvobDA7vQ"},"images":[{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"1"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"2"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"3"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"4"}]},"id":"#3","type":"component","lock":false,"position":2},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

Diving into the topic, they discuss the importance of nomenclature of dual CCR. **Independent dual CCRs or bailout CCR?** They each agree that the terminology, simplicity, and appropriate training are critical aspects. Use of dual CCR depends very much on the **diving environment, wreck vs cave diving, and on the unit configuration itself**. A [backmount](https://www.divesoft.com/en/products/ccr-liberty/ccr-liberty-bmcl-fmcl) vs [sidemount](https://www.divesoft.com/en/products/ccr-liberty/ccr-liberty-sidemount) unit, team and work involved in the dive, open-circuit gas also play critical factors of [dual CCR or bailout CCR](https://www.divesoft.com/en/blog/jakub-simanek-steve-bogaerts-and-brett-hemphill-about-bailout-and-dual-rebreathers).\n\nIn addition, they touch on the topic of **training standards**, dive community, and the responsibility of dual CCR divers. Is bailout CCR diving for everyone? Is it limited to a specific group of divers? They think the call for standards is necessary for the safety of people showing the level of diving experience before using bailout CCR. Additionally, understanding of the complexity of using the two individual units **require obvious work in time, discipline, mentorship, and patience**.\n\nThey also discuss the **potential dangers and issues of diving fully electronic CCRs vs manually CCRs**.

During immediate emergencies, such as a unit flood or CO2 issues, he describes the importance of carrying an open circuit during the dive, that contains a suitable bottom mix for the dive. \n\nHe then talks about the special mode, bailout **Standby Mode**, designed for diving with a [bailout rebreather](https://www.divesoft.com/en/blog/jakub-simanek-steve-bogaerts-and-brett-hemphill-about-bailout-and-dual-rebreathers).

","content":"His diving career started back in 1995 in the Pacific N

2orthwest. In 1999, he joined the International Underwater Cave Rescue and Recovery (IUCRR) as one of the founding members. In 2003, he founded Cave Adventurers. Edd became a local hero in 2012 when he successfully **rescued four people in three different rescues at Merritt's Millpond in Jackson County, Florida**. Edd is now the Safety Director for the NSS-CDS and was awarded the Life Saving Award in 2013. At the 2019 NSS-CDS International Conference, Edd received the Lifetime Achievement Award. Additionally, the NSS-CDS named an award after him, the \"Edd Sorenson Life Saving Award\".\n\nEdd begins with his early diving experience and how he got into cave diving, about the IUCRR group and the purpose behind it. He then shares tales of the recovery and incredible rescue stories that he performed over the years, including **the most recent rescue of Josh Bratchley**. Together, Joe and Edd watch the video of this rescue and comment on challenges, such as the **NO-dive plan and unknown environments, of these incredibly demanding operations**.\n\nLater in the chat, Edd also talks about the gear and his involvement in innovating [sidemount diving](https://www.divesoft.com/en/products/ccr-liberty/ccr-liberty-sidemount) equipment. Edd looks back on his \"First Open Water Dive\" Sidemount course and his participation in Liberty CCR development. He also explains how cave diving with the Liberty sidemount gives him more freedom and why he dives with a Liberty dual rebreather setup. He also points out some challenges and benefits of this particular configuration. Joe and Edd finish off by talking about [innovation in technical diving](https://www.divesoft.com/) and the diving community. In the end, they both agree that in the world of technical diving, even if there is some sort of competition, **they all dive together as friends**.\n\nWatch the video now. 🔻\n","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":704411,"hash":"39a83869655d8f116ed4533e494247daefd3767e","id":"ckvjns1h2qstd0776lt7fe3sy","filename":"18-edd-sorenson-divetalks.png","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"GalleryAndVideo","data":{"title":"DIVETALKS Live #10 | Interview with Edd Sorenson","video":{"type":"embeddedVideo","url":"https://www.youtube.com/embed/2TQgZiLMBlo"},"images":[{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"1"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"2"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"3"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"4"}]},"id":"#4","type":"component","lock":false,"position":2},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#5","type":"component","lock":false,"position":3},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/channel/UCHI2-kHmfoUlAdhQXPKl8lA/featured","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":5}],"id":"root","idBuffer":"#6","lastCommit":"e8822f42-b47f-4510-a82f-34291c57ce91"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:ckvjneeih2t9t08642g88uzdj.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:ckvjneeih2t9t08642g88uzdj.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:ckvjneeih2t9t08642g88uzdj.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:ckvjneeih2t9t08642g88uzdj.annotations.0":{"key":"title","value":"Divetalks with Edd Sorenson: rescue stories, sidemount diving and innovation in technical diving","__typename":"PageAnnotation"},"PageTranslation:ckvjneeih2t9t08642g88uzdj.annotations.1":{"key":"image","value":"{\"mimetype\":\"image/png\",\"size\":704411,\"hash\":\"39a83869655d8f116ed4533e494247daefd3767e\",\"id\":\"ckvjns1h2qstd0776lt7fe3sy\",\"filename\":\"18-edd-sorenson-divetalks.png\",\"category\":\"divesoft/\",\"type\":\"image\"}","__typename":"PageAnnotation"},"PageTranslation:ckvjneeih2t9t08642g88uzdj.annotations.2":{"key":"perex","value":"Welcome to another episode of DIVETALKS, in which Joe Bosquez has a chat with Edd Sorenson.

","content":"[Jill](https://www.divesoft.com/en/ambassadors/jillheinerth) and [Jeff ](https://www.divesoft.com/en/ambassadors/jeffbozanic) start talking about their diving history, involvement in the CCR development and current diving practices. The control system of mCCR vs eCCR is one of the main aspects of this talk and defining the eCCR and the difference between gas control and gas control-dive management. Jill explains how electronic components in CCR adding a sort of \"safety net\". \n\nShe believes that **there is not such a thing as purely mechanical or electronic CCRs**, but instead, all CCR are a combination of two systems. In addition, Jeff shares his working/diving experience and reflects on why he likes to use the eCCR, along with mCCR, during his work underwater. He thinks the combination of **the two systems together gives an extra \"safety net\" during task loading when the diver is most likely to pay less attention to your CCR**. Jill builds on the importance of knowledge of manual operation of CCR manually in the event of an electronics failure underwater. So, is eCCR safer than mCCR? This and other questions about eCCR, including diving preferences, training, dive plan, cave diving, mouthpiece retaining straps, and more.\n\nIn the second half, Jill and Jeff talk about the **history of eCCR**. They share their stories on their early CCR diving, which included early prototypes that did not involve any electronic and even sensors, and how problematic maintenance and their use where. They also talk about the future sensor development and sensor technology, which is still constantly evolving. They also discuss **the changes over time in terms of technical diver mindset,** modifying CCR and impacts, software of user interface. Finally, you will learn about the diving safety rule and some thoughts about eCCR diving. \n\nJill is an underwater explorer, writer, photographer, speaker, and filmmaker. A pioneer of [technical rebreather diving](https://www.divesoft.com/en/products/ccr-liberty/philosophy), she has led expeditions into icebergs in Antarctica, volcanic lava tubes and submerged caves all over. Jeff's experiences include leading and participating in over 60 diving expeditions in the past 40 years. Expeditions that have taken him to places like Palau, the Canary Islands, Mexico, and even Antarctica. His textbook Mastering Rebreathers has been used by countless students and dive instructors.\n\nWatch the Video Now! 🔻\n","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":745068,"hash":"e7a53c18dc6f96a656578444946c47d95d1cd1e3","id":"ckw6es6z9zmc30776qmpiuo98","filename":"20-blog-jill-jeff-eccr.png","category":"divesoft/","type":"image","alt":" Jill Heinerth and Jeff Bozanic: eCCR vs mCCR discussion"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"GalleryAndVideo","data":{"title":"mCCR vs eCCR #2 | with Jill Heinerth and Jeff Bozanic","video":{"type":"embeddedVideo","url":"https://www.youtube.com/embed/b9tc4abjmXY"},"images":[{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"1"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"2"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"3"},{"image":{"recommendedSizes":{"width":"1600","height":"900"}},"id":"4"}]},"id":"#4","type":"component","lock":false,"position":2},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#5","type":"component","lock":false,"position":3},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/channel/UCHI2-kHmfoUlAdhQXPKl8lA/featured","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":5}],"id":"root","idBuffer":"#6","lastCommit":"62f56c25-39fd-4250-95b8-9d4ebea42a89"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:ckw6e9xgh0mpc0864g5mgoulg.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:ckw6e9xgh0mpc0864g5mgoulg.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:ckw6e9xgh0mpc0864g5mgoulg.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:ckw6e9xgh0mpc0864g5mgoulg.annotations.0":{"key":"title","value":"Divesoft.blog / Jill Heinerth and Jeff Bozanic: eCCR vs mCCR discussion","__typename":"PageAnnotation"},"PageTranslation:ckw6e9xgh0mpc0864g5mgoulg.annotations.1":{"key":"perex","value":"This time Joe is hosting Jill Heinerth and Jeff Bozanic discussing electronic CCRs, their history and how they have changed over time.

The correctness of the mix composition must be established by the technology used to prepare it. \n\nThe correct preparation of breathing mixes for diving (nitrox – oxygen-enriched air) requires special knowledge and experience which is possible to gain, for example, through an appropriate course.

We recommend that such calibration be performed at least once a month The analyzer is equipped with built-in barometer sensor, which compensates for changes in altitude while traveling to dive sites.  \n\nCalibration of the sensor is performed as either single-point or two-point or three-point. During single-point calibration, the content of oxygen in air, which is known and constant (20.95 %), is measured by the sensor. The calibration constant of the sensor is set so that the instrument displays 21.0 % (after rounding).  \n\nTwo-point calibration proceeds in the same manner as single-point calibration, but uses two calibration gases – pure oxygen and air. Two-point calibration is more arduous as it requires the use of oxygen. However, it provides more precise results during measuring.  \n\nThee-point calibration is recommended for measuring hypoxic mixes, containing less than approximately 15 % oxygen. In this case, the third calibration gas should be a gas with zero oxygen content, i.e. pure helium or argon.  \n\nCalibration of the oxygen sensor is started by pressing the **| CAL |** key at any time during the measuring.  \n\nAs the first step of calibration, we must choose between single-point, two-point or three-point calibration using the **| ˄ |** and **| ˅ |** keys and confirm the selection using the **| OK |** key.  \n\nIt is then necessary to choose the oxygen content in the calibration mixture.  \n\nThe oxygen content is adjusted by tenths of a percent by pressing the **| ˄ |** key (to increase the content) or the **| ˅ |** key (to decrease the content).

Upon setting the desired values, confirm the data using the **| OK |** key.  \n\nFor quickly setting typical values when setting the oxygen content it is possible to use the **| CAL |** key, which sets the oxygen content at 21 % in the case of the first calibration point or 100 % at the second point and 0 % at the third point.  \n\nUpon setting and confirming the calibration of gases, calibration of the sensor begins. The current calibration point, sensor voltage in millivolts and the temperature of the gas appear on the display.  \n\nAfter the temperature and voltage have stabilized (however, at least after ten seconds), the STABLE prompt appears, which means that it is possible to confirm the performed calibration using the **| OK |** key.

Rather than discarding the gas after a single breath, it processes the gas and returns it to the diver.\n\nThis approach reduces gas consumption significantly compared to open-circuit scuba. The principle itself is simple.\n\nReuse the gas instead of throwing it away.\n\nMaking that happen safely underwater requires several components working together.\n\n![Gas circulating through a closed breathing loop inside a rebreather.](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/bfd6fcf0ed3de2a7650ed1b51b0bd49c8ca264b6_23-oxygen-ccr.png)\n\n**New to rebreathers? \\> [Rebreather vs Open Circuit: What's the Difference?] (https://www.divesoft.com/en/blog/rebreather-vs-open-circuit-what-s-the-difference)\n**\n## What Happens to Every Breath?\n\nAt the surface, the air we breathe contains approximately 21% oxygen. During each breath, only part of that oxygen is consumed by the body. The remaining oxygen is exhaled together with carbon dioxide, water vapour, nitrogen, and other gases.\n\nIn open-circuit scuba, the entire breath is released into the water.\n\nA rebreather takes a different approach. When the diver exhales, the gas remains inside a closed breathing loop rather than leaving the system. Before it can be breathed again, carbon dioxide must be removed and the consumed oxygen replaced.\n\n![Inhalation and exhalation of a diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/2b64de4733c830c6434e1e340ed0c1caa4339f5e_inhale-exhale.png)\n*Figure 1 Inhale and Exhale*\n\n## The Breathing Loop\nThe breathing loop is the pathway through which gas circulates inside the rebreather.\n\nAs the diver breathes, gas moves continuously through the loop. One side carries exhaled gas away from the diver. The other side delivers processed gas back for inhalation.\n\nCounterlungs within the system expand and contract as breathing takes place, helping maintain a comfortable breathing volume inside the loop.\n\n![Oxygen and diluent cylinders used in a closed-circuit rebreather system.](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7a140d762c26a6bea9244294b91ed00cadcd4a65_23-eccr.png)\n\n*Figure 3 **Electronically controlled Closed Circuit Rebreather (eCCR)** – 1.

The scrubber allows the remaining breathing gas to stay in circulation.\n\n![Carbon dioxide scrubber used to remove CO₂ from exhaled gas.](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/373a0a09c1b1aeb09b01e27f3a5bcc84fde6a737_23-warm-rebreather.png)\n\n## Why Oxygen Must Be Added\nWhile most of the breathing gas remains in the loop, oxygen does not. The body continuously consumes oxygen during the dive. That oxygen must be replaced to maintain a breathable gas mixture.\n\nIn an electronically controlled rebreather, oxygen is added automatically as needed. The amount added depends on the oxygen concentration inside the loop.\n\n**Learn why efficie

2nt gas management is one of the reasons divers choose CCRs \\> [Why Do Divers Use Rebreathers?](https://www.divesoft.com/en/blog/why-do-divers-use-rebreathers-ccr-benefits-explained)**\n\n## Why Oxygen Sensors Matter\nOne of the most important components in an electronically controlled rebreather is the oxygen sensor.\n\nThese sensors continuously measure the oxygen concentration inside the breathing loop. The information is displayed to the diver and used by the control system. If oxygen levels fall below the selected setpoint, the system adds oxygen to return the mixture to the desired value.\n\nThis process continues throughout the dive.\n\n## The Solenoid Valve\nThe component responsible for adding oxygen automatically is called a solenoid. A solenoid is an electronically controlled valve connected to the oxygen supply.\n\nWhen the control electronics determine that oxygen needs to be added, the solenoid opens briefly and injects oxygen into the breathing loop. The valve then closes again.\n\nThis process occurs repeatedly throughout the dive as oxygen is consumed.\n\n## What Is Diluent and Why Is It Needed?\nA rebreather contains two primary gas supplies. One contains oxygen. The other contains diluent.\n\nDiluent is used to maintain a breathable gas volume inside the loop and to control the oxygen concentration at different depths. Depending on the type of dive, the diluent may be air, nitrox, trimix, or another suitable breathing gas.\n\nAlthough oxygen receives most of the attention, a rebreather cannot operate correctly without diluent.\n\n## Bringing It All Together\nA rebreather may appear complex at first, but each component has a specific task.\n\nThe breathing loop keeps the gas circulating. The scrubber removes carbon dioxide. Oxygen sensors monitor the oxygen concentration. The solenoid adds oxygen when needed. The diluent helps maintain an appropriate breathing mixture.\n\nTogether, these components allow the diver to recycle breathing gas rather than releasing every breath into the water. Understanding how a rebreather works is only part of the story.\n\nOne of the most common questions new divers ask is how long a rebreather can stay underwater. The answer depends on oxygen consumption, scrubber duration, workload, water temperature, decompression requirements, and dive planning.\n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/1094e1ecde9685e85f7b551adf5a96839473396c_divesoft-8.jpg)\n\n\n**Learn more → \\> [How Long Can You Stay Underwater With a Rebreather?] (https://www.divesoft.com/en/how-long-can-you-stay-underwater-with-a-rebreather)**\n\n## Explore More About Rebreather Diving\n* [Why Do Divers Use Rebreathers?] (https://www.divesoft.com/en/blog/why-do-divers-use-rebreathers-ccr-benefits-explained)\n\nExplore the practical reasons divers choose CCRs, from longer dives and reduced gas consumption to comfort and underwater observation.\n\n* [Rebreather vs Open Circuit: What's the Difference?] (https://www.divesoft.com/en/blog/rebreather-vs-open-circuit-what-s-the-difference)\n\nLearn how closed-circuit and open-circuit systems manage breathing gas differently and how that affects the diving experience.\n\n* [How Long Can You Stay Underwater With a Rebreather?] (https://www.divesoft.com/en/how-long-can-you-stay-underwater-with-a-rebreather) \n\nUnderstand the factors that determine dive duration, including oxygen consumption, scrubber duration, workload, and dive planning.\n\n* [Why Recreational Divers Use Rebreathers] (https://www.divesoft.com/en/blog/why-recreational-divers-use-rebreathers)\n\nDiscover why many CCR divers spend most of their time well within recreational depth limits.\n\n* [Why Underwater Photographers Use Rebreathers] (https://www.divesoft.com/en/blog/why-underwater-photographers-use-rebreathers)\n\nLearn why photographers, filmmakers, and wildlife observers often appreciate quieter dives and longer observation times.\n\n \\>  [Explore Liberty CCR] (https://www.divesoft.com/en/products/ccr-liberty)\n\n- Author: *[Divesoft] (https://www.divesoft.com/)*\n","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":1199734,"hash":"84373c9a9617b4d1054ad4c715fb9e32bdea965e","id":"ckz7yjonc2eq60776u0v3dizh","filename":"23-blog-what-is-rebreather.png","category":"divesoft/","type":"image","alt":"A closed-circuit rebreather combines the breathing loop, scrubber, sensors, oxygen supply, and diluent into a single integrated system."}},"id":"#2","type":"component","lock":false,"position":1},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/channel/UCHI2-kHmfoUlAdhQXPKl8lA/featured","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":6}],"id":"root","idBuffer":"#7","lastCommit":"17ea8ba4-6675-4de6-b17e-574a015e924c"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:ckz7y82vv5kaq0858eioy41o0.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:ckz7y82vv5kaq0858eioy41o0.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:ckz7y82vv5kaq0858eioy41o0.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:ckz7y82vv5kaq0858eioy41o0.annotations.0":{"key":"perex","value":"Most divers learn to dive using open-circuit scuba.\nYou breathe from a cylinder and exhale into the water.\nA rebreather works differently.\nInstead of releasing every breath as bubbles, it keeps most of the gas inside the system, removes carbon dioxide, replaces the oxygen that has been consumed, and allows the remaining gas to be breathed again.\nUnderstanding that process is the first step to understanding how a rebreather works.","__typename":"PageAnnotation"},"PageTranslation:ckz7y82vv5kaq0858eioy41o0.annotations.1":{"key":"title","value":"What Is a Rebreather and How Does It Work?","__typename":"PageAnnotation"},"PageTranslation:ckz7y82vv5kaq0858eioy41o0.annotations.2":{"key":"image","value":"{\"mimetype\":\"image/png\",\"size\":1199734,\"hash\":\"84373c9a9617b4d1054ad4c715fb9e32bdea965e\",\"id\":\"ckz7yjonc2eq60776u0v3dizh\",\"filename\":\"23-blog-what-is-rebreather.png\",\"category\":\"divesoft/\",\"type\":\"image\",\"alt\":\"A closed-circuit rebreather combines the breathing loop, scrubber, sensors, oxygen supply, and diluent into a single integrated system.\"}","__typename":"PageAnnotation"}

These steps will outline the tools you'll need to explore an underwater world without bubbles.","content":"**1. Motivation  **\n  \nIf you're reading this article, you are probably already interested to learning more of what it takes to get a rebreather. There are many reasons to get a [closed-circuit rebreather](https://www.divesoft.com/en/products/ccr-liberty/philosophy). It could be **greater dive and decompression efficiency, gas savings, deep dives, long cave dives, silence, or simply because you're a big fan of technology** and want to treat yourself to something better. \n\nHonestly, you don't really need to have a rational reason to justify getting a rebreather. People also don't get expensive and fast cars or motorbikes just to be faster at work. We've all seen the amazing photographs of divers in extreme places with all the equipment. Other times rebreather divers look as if they are embarking on a space walk to the other side of the moon! Rebreathers do tie into our sense of adventure to go where few others have been. If you want to get a rebreather simply because it's cool, then have at it! But you may have to find some justification for your wife or husband. \n\n[The previous article](https://www.divesoft.com/en/blog/what-is-a-rebreather-do-i-need-one-as-a-recreational-diver) can help you with that.  \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7f82f8317f7778e9ba56b6fe98e8bb9854116b5e_24-motivation.png)\n  \n**2. Experience **  \n  \nIn the early days, rebreathers where reservered for the elite few and the extreme extreme divers. **Nowadays, there are many opinions that you can begin with a rebreather with little to no experience.** In my opinion, this is a mistake. \n\nA rebreather is, after all, a significantly more complex system which requires the active engagement of the diver both in its preparation and during the dive itself. In order to feel safe and enjoy diving with a CCR, **you need to already feel comfortable in the water and not be bothered by basic diving skills**. Divers that are early in their career are getting used to the different aquatic environment, reduced visibility, moving underwater, basic equipment control and buoyancy. \n\nBy the time you strap on a rebreather, you must have mastered these skills to the point that they are second nature. If you are overzealous in moving quickly to CCR without mastering the basics of diving itself, **you may become quickly overwhelmed, making it easy to miss important steps or warnings**. This can have really serious consequences and has happened more than once.   \n  \nUniversally, experience is expressed in terms of the number of dives, but it is clear to everyone that this can be very individual as not all dives are the same. **The entry [requirements of training agencies](https://www.divesoft.com/en/events-blog/ccr-training-from-the-perspective-of-training-agencies) into CCR courses vary widely and range from 18 to 100 dives.** I find the lower end of that range to be totally inadequate. \n\nI'm willing to concede that it may be satisfactory for a discovery dive, since you are in a safe environment under the supervision of an experienced instructor the entire time. However, an independent CCR diver course should only come into play when I am able to move reliably and safely underwater, the drills learned in the OWD and AOWD courses are a non-encumbering routine for me, and I can perform them anywhere and anytime regardless of the environment I am diving in.\n\nA very important skill that I think should be mastered at least at **a basic level is carrying and using a stage cylinder**. When diving with a rebreather, you will always need a bailout cylinder, which is a gas supply in a regular open circuit dive cylinder that differs little from a stage cylinder. If you already enter the CCR course with this experience, you will be able to focus on the rebreather diving itself and the bailout cylinder will be a given that will already feel natural to the diver and require no additional attention.   \n  \nIf you follow the above recommendations and consider your own experience, you will probably come to the conclusion that 18 dives is insufficient in any case, and we will be more likely to be somewhere around that 100 dives in reality. Divers with this number of dives are more experienced, they know their way around the water, the basic exercises are not difficult for them, and they have probably already had some close calls that gave them valuable experience and respect.   \n  \nSome training organizations even offer the opportunity to begin an OWD course right away at a recreational rebreather. This idea is an interesting one and relies on divers learning everything straight from the start, so they won't struggle with learning everything from scratch when they move on to a rebreather. But the arguments I made earlier tend to refute this claim. **A diver has to learn with an open circuit anyway, because they will be switching to an open circuit in an emergency situation**. So, if we wanted to teach a diver everything honestly and from scratch, then we would have to take him through all the skills and such a course would be very long and therefore very expensive. If someone offers you a quick and easy solution, beware. There are no shortcuts to the top.  \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/3de8b02f617a119826336abe419aac323eef477c_24-experience.png)\n \n**3. Training and certification  **\n  \nAs indicated in the previous section, a critical prerequisite for becoming a rebreather diver is training with the specific device and certification from a recognized training agency. Without this, it is not possible to buy the device at all. All rebreather manufacturers either sell their devices directly through instructors or want to at least provide proof of successful completion of training. \n\nThere is no universal training. There is **specific training for each type of apparatus and your certification card will have the type of apparatus 

2you are trained for marked on it**. I will cover the training, its requirements and instructor selection in detail in my next article. Specific training of each unit comes to the fact that each unit has critical components that differentiate them that require different techniques to build and dive them. Enough that specific training is required.\n  \n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/a9c5a3ee2b8297344a60bf42826a8af08e4f3b66_24-training.png)\n\t\n**4. The unit  **\n  \nDo I have to get a rebreather if I want to start rebreather diving? Can't I rent one somewhere? Of course, you can, although these are rather exceptions. However, any instructor will tell you in a course that **once you start diving on a rebreather, you should already be diving primarily on a rebreather**. \n\nIt's like flying. If you don't take enough hours a year, you lose the habits you've learned and the safety of CCR diving decreases rapidly. If you only have the device on loan occasionally, you'll have a hard time taking it on every dive and a hard time gaining the necessary experience and habits. \n\nSo, if I may recommend, **if you decide to go the rebreather diving route, you need to own your own apparatus**. If you want to become a rebreather diver, best you own a rebreather. You can, of course, go about it the right way, and take several training courses for different apparatus before you choose to buy the one that suits you best. This is an honest, albeit, long and expensive journey. I've personally encountered this approach, and the person who went through it this way was certainly no beginner, but a world-renowned cave diving expert. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/6beb4d3358215d806584857e0f68d05bbe330d10_24-unit.png)\n \n**5. Additional equipment  **\n  \nIf you are to become a rebreather diver, then you will be needing to get a rebreather. From this, it is safe to assume that you already have all your basic diving equipment. Of course, you can't do without a suitable exposure suit, ABCs and other elementary items of equipment.  \n  \nWhat may be new to you, however, is a **bailout cylinder with an appropriate regulator**. A bailout cylinder, as I've already written, is not much different from a stage cylinder. There are some differences, though. While stage cylinders for technical open circuit diving are almost exclusively recommended in aluminium, steel cylinders are not taboo for bailout cylinders either. A properly selected lightweight steel cylinder will always be more compact than an aluminium one, will not change its buoyancy significantly, and most importantly, will hold more gas because we can pressurize it a bit more than an aluminium one. \n\nThe rigging of such a cylinder is becoming more and more like a sidemount cylinder rather than a traditional stage cylinder. Divers secure them with a bolt snap on the bottom, and a bungee cord around the top end around the valve from the divers harness. This allows the bottle to be carried much closer to the diver without it constantly bobbing and clinking under the diver's body. The biggest benefit is a more streamline profile, which will make swimming much easier.  \n  \n**The bailout cylinder regulator** is also slightly different from a traditional stage regulator. In addition to the second stage and pressure gauge, the first stage is also equipped with a medium pressure hose with an inflator bayonet quick connector. The latter is used when I need to supplement gas from an external cylinder because the rebreather cylinder is empty, has a valve failure, or I just want to save gas in the on-board rebreather cylinder. \n\nThe length of the regulator's medium pressure hose remains the same as the classic stage, i.e. 100 cm (40 inch). We need to be able to run it comfortably behind the neck from left to right and into the mouth.  If we have a second stage permanently placed by a rubber band around the neck for immediate switching to the open circuit, then the regulator must be equipped with an additional second stage in case of providing gas to a partner in an emergency.  \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/a7f8591702d72b4e0a034c61ff8ef0cd32e6fd9a_24-additional-equipment.png)\n\n**6. The will and determination to maintain the device regularly ** \n  \nTaking care of the rebreather is essential for its perfect operation. I tell my students that **80% of dive safety is ensured on land before the dive, and unit preparation is the main component of land preparation**. Caring for a rebreather involves a more complex assembly than is the case with a conventional scuba unit. \n\nThere is also **the need to perform pre-dive tests, pre-breathing, and to clean the unit, disinfect the breathing loop and dry it out after the dive day**. It's a bit more work that we must accept and not skip, even after many successful CCR dives. It's a tax on the amazing efficiency the apparatus brings us, and we must be willing to pay it if we want to keep the apparatus safe. Of course, regular annual servicing by service technicians or directly by the manufacturer is a must. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/a8420e2e8829bfd049da0cc400ba17cb1f521647_24-maintain.png)\n  \n**7. Decision ** \n  \nThe most important thing at the end. By now you should be equipped with the basic 

2information on what entering a bubble-free world entails and have the pros/cons are your disposal. The decision is up to you and you should consider all aspects carefully. \n\nExpect that, in addition to the purchase price, you will be forced **to invest annually in replacing oxygen sensors, and you will use 2.5 kg of sorbent for every 6 hours or so of diving**. These are things that must not be skipped and must therefore be taken into account. Nevertheless, I believe that the benefits of CCR are so great that the cost of acquiring and operating it easily outweighs them.  \n  \nI hope this article has helped you make a better decision in whether to get a rebreather.

Now, the surface interval (and oxygen calibration age) will not be affected by time change - eg. adjusting the Liberty time between two dives. However, if you remove the battery jumpers when storing the Liberty for a prolonged period, the internal real time clock will eventually stop. This happens after more than two days with the jumpers removed. After that, the time will not increment anymore and the surface time / oxygen calibration age will not be incremented as well. Keep this in mind that these values can be inaccurate if you remove jumpers for storage. This primarily only applies for Liberty units that are pre 2021Edition (HW 1.X).

Turn the Liberty on, or remove jumper before updating your FW.  \n\n**Error corrections**  \n* Fixed unwanted behavior when set GF low > GF high\n* Fixed solenoid staying excluded even when other CU comes back online.\n* Fixed inability to disable first diluent with BoCCR functions turned off.  \n\n**BO RMT changes in Bailout CCR mode**  \n\nWhen bailout CCR options enabled in \"Setup / Miscellaneous / BOCCR settings\", the original OC bailout remaining time calculation makes no sense. So in bailout CCR mode, the \"turnaround time\" or \"BO RMT\" is calculated in the \"Standby CCR\" mode only. On the (main) unit switched to CCR mode, \"BO RMT\" on the TTS screen shows static text only - \"Check BO CCR\". And the turnaround time is calculated on the \"bailout\" unit, visible on the sensors screen, instead of a indirect ppO2. Once you switch your bailout unit from standby to full CCR mode, the sensors screen will show the indirect ppO2 as usual. And the \"BO RMT\" on the TTS screen will read \"Check BO CCR\", since the unit you are breathing at the moment is \"main\", and the other is in the \"bailout\" role. The bailout CCR remaining time is calculated from: stack time, CNS and battery level, including the necessary ascent time. So if you have set stack time notification to 4h, and you are 1h in the dive, with TTS of 2h, beginning your ascent, the BO RMT will read 1h. That is if your stack time is the limiting factor and not for example the CNS. If you use tank pressure transmitters, then the oxygen pressure is also evaluated. If there is enough oxygen for the ascent and decompression, using metabolic rate of 1.6l/min. The diluent pressure is only checked for whether is not lower than set limit (eg. too deep descent with little diluent in cylinder).","title":"Liberty 2.12.1 (6741)","isTitleBold":true},{"id":"14","subtitle":"**3rd December 2019**\n<br><br>\n**ATTENTION**\n* This update is not compatible with handset (HS) bootloader version <3.6 (year of manufacture 2015 and older) !\n* If your HS keeps restarting after updating to FW 2.12, then you have old bootloader version\n* Detailed instructions how to update, are attached in the zip with the rest of FW.\n* You can see the bootloader version immediately after connecting the battery jumpers, before the topology screen comes on.\n  * If you see only a red Divesoft logo, you are A OK (version >3.10)\n* In any other case you should see few lines of text, on the first one is bootloader version.\n   \n**New features**\n\n* Configurable lower button function, see below.\n* Switchable HUD signalization as a relative deviation from current setpoint, see below.\n* Ascent plan as a dive screen (disabled, enabled, deco only).\n* O2 cell tester menu - calibrate O2 cells directly after test, and release IP pressure using solenoid.\n* Atmospheric pressure calibration, on units without fine pressure sensors only (marked \"F\").\n* Inclinometer application (new horizontal calibration is necessary before first use)\n* Option to calculate TTS and ascent with current SP instead of high SP (Setup / Decompression / Planner / Ascent SP [High, Current])\n* Helium blind plugs support\n\n\n**Changes**\n* Decompression algorithm update, see below.\n* Helium sensor calibration tries alternate presets where default does not suffice.\n* Above stop alarm is now progressive (OC only).\n* END value is calculated for MOD depth\n* High ppO2 limit is split to bottom and deco settings, see below (OC only).\n* Bailout CCR options are hidden by default, enable them in Miscellaneous.\n* With BoCCR enabled - the first row in dive menu is\nCCR standby (instead of OC bailout).\n* Improved menu and editor graphics, option to draw all menu in bigger font (...

I thought about how I would be forced to modify gear, the way I move and buoyancy. But as I continued to learn, I found many issues that I had never considered. **I got a first-hand opportunity to enlighten myself when we organized a demo event for the [rebreather ](https://www.divesoft.com/en/products/ccr-liberty/philosophy)with the wheelchair sports club [SKV Prague](https://www.skvpraha.org/)**.  \n\nI was worried about how this event would go. Despite never having dove with anyone that had disabilities, I have had some experience working with them and always admired their ability to adapt. Thus, I tried to carefully prepare and think of anything that may be an issue. Fortunately, I was not alone. We had the perfect team from Divesoft to help me with the dive equipment and set up, as well as other instructor's experience of working with divers with disabilities. **Thanks to this team, I learned how to work with the disabled in the water**.  \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/22177b9ee1e17483310f341d303fdf6f2f7d542e_25-diver.png)\n\nIt should also be noted that the members of SKV Prague are not beginners. Most of them have a complete diving training. **They dive regularly with their instructors to flooded quarries and the annual trip to the sea in Elba, Egypt, or Thailand.** Scuba diving is a great opportunity for them to enjoy the freedom of weightlessness and moving underwater. \n\nEach of the participants had slightly different needs. Some were paralyzed in the lower half of their bodies, and others were even quadriplegics. This means that their arms are partially or completely immobile. Some were able to get into the pool with minimal assistance, others were unable to do so without the help of others. **All of them were already prepared in wetsuits, which they said they can do very well and as quickly as healthy divers.** \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/057d61abc1d16b4f29410a6e97ae9bc9d27fecea_25-divers.png)\n\nWe were then able to get them into the water and get them comfortably into the rebreather harness after the initial training. This was followed by a test breathing from the apparatus. **As soon as the diver signaled that he was ready, we flipped him face down on the surface, have them breathe for a few seconds and flipped him back face up**. This was so that we and the diver could see if everything was functioning properly and the diver was ready to dive. \n\nCommunication is very interesting. For divers in wheelchairs it is no different since they have their hands to demonstrate clear hand signals, but quadriplegics are quite limited or completely unable to use hand signals. For instructors, this is a big deal because **the only way to react or signal a problem is for the diver to move his/her head or even just the eyes**. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/da53a6a3a9de2ca84ace74119995d77709447bcb_25-liberty.png)\n\nTherefore, it requires much more concentration on the client than in a normal training or test dive. We absolutely cannot take our eyes off the client for even a second, plus we need help to maintain the ideal breathing position. **The uncontrollable legs combined with a counterlung and front body movements cause a strong heads-up roll**. Thus in the beginning we had to help the client completely until they got used to the new device and learned how to find a good position on their own. \n\nFor quadriplegics, constant physical contact was necessary at all times, but some divers with healthy arms were able to swim on their own after a while. Even behind their mask they could not hide their expressions! **They then commented on their first experiences with the rebreather, amazed at the silence and ease of breathing.** Most of them found it almost strange, but this feeling is quite familiar to anyone who has tried it for the first time with Liberty. You could see it all over their faces that they loved it, but they didn't have the same confidence as with the open circuit they've long gotten used to. They were all extremely grateful for the opportunity to try such a machine and some regretted not being able to take it home or on their next trip to the seaside. Who knows, maybe one day it could happen! \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/456abaf368d5d9827987dd9a1e1fc9b30a871d92_25-togerther.png)\n\nIt is such an inspiration to work with people who are able to cope with their hardship and manage an extraordinary life despite such unimaginably difficult hurdles to face. It is amazing despite having the basic ability to provide for themselves they do not give up their daily routines, current work, and hobbies. Even finding new ones! However, the work that instructors who introduce diving to the handicap do such an incredible job. I was able to see first-hand this important work to help them fulfil their dreams to be free in a weightless world. \n\n* [Jakub Šimánek](https://www.divesoft.com/en/about-us/jakub-simanek), Divesoft Factory IT\n","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":1158125,"hash":"5f00b760a3f1f32d8c93d173530c17895c749e1f","id":"cl10kem4lmevx07768vjgcota","filename":"25-demo-day-wheelchair.png","category":"divesoft/","type":"image","alt":"Divesoft DEMO day with divers in wheelchairs from SKV team"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

V těchto případech lze analyzátor použít pouze jako pomůcku pro zvýšení pravděpodobnosti, že bude zjištěno nesprávné složení směsi před jejím použitím.Správnost složení směsi musí být dána technologií její přípravy.  \n\nSprávná příprava dýchacích směsí pro potápění (nitrox – vzduch obohace

Princip funkce**\n\nPopsaný princip měření platí pouze pro směsi vzduchu, kyslíku a helia.  \n\nPro stanovení obsahu kyslíku je použit elektrochemický sensor. Napětí na výstupu senzoru je úměrné obsahu kyslíku v analyzované směsi. Senzor má omezenou životnost a úměrnost závislosti napětí na obsahu kyslíku se během doby mění, proto je nutné jej pravidelně kaliborovat. Lze zvolit mezi jednobodovou, dvoubodovou nebo tříbodovou kalibrací. Jednobodová kalibrace je rychlá, zejména pokud se jako kalibrační směs zvolí vzduch. Pro vyšší přesnost měření se používá dvoubodová kalibrace se dvěma různými se směsmi, zpravidla vzduchem a čistým kyslíkem. Pro výrazně hypoxické směsi, tj.směsi obsahující méně než asi 15 % kyslíku se doporučuje použít tříbodovou kalibraci. Jako třetí plyn pro kalibraci má být v tomto případě použit plyn s nulovým obsahem kyslíku, tedy čisté helium případně argon.\n\nObsah helia se stanovuje na základě měření rychlosti zvuku v analyzované směsi. Rychlost zvuku závisí na obsahu helia, kyslíku a na teplotě směsi. Závislost rychlosti zvuku na tlaku je malá a v okolí normálního atmosférického tlaku ji lze zanedbat.\n\nPři teplotě 0°C je rychlost zvuku přibližně 970 m/s v čistém heliu, 330 m/s ve vzduchu a 315 m/s v čistém kyslíku. Zvýšením teploty o jeden stupeň se ryc

2hlost zvuku zvýší přibližně o 0.175 %. Rychlost zvuku ve směsi je popsána nelineární funkcí teploty, obsahu kyslíku a obsahu helia.\n\nObsah helia se určuje z naměřené rychlosti zvuku, teploty směsi a obsahu kyslíku. Při měření koncentrace helia je proto důležité mít správně kalibrovaný kyslíkový senzor nebo znát obsah kyslíku a zadat jej do přístroje.\n\nRychlost zvuku se měří přímo jako časový rozdíl mezi přijetím akustického impulsu dvěma mikrofony. Měří se střídavě v obou směrech, aby bylo možné výpočtem eliminovat proudění plynu v sondě. Akustické impulsy jsou slyÅ¡et jako slabé cvakání v režimu měření helia.\n\nPlyn se do analyzátoru přivádí z omezovače průtoku, který je připojen na lahev se stlačeným plynem a pomocí trysky omezuje průtok odebíraného plynu na množství potřebné pro analýzu.\n","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#56","type":"component","lock":false,"position":17},{"name":"Divider","data":{"color":"darkGray"},"id":"#57","type":"component","lock":false,"position":18},{"name":"SectionDivider","data":{"title":"03.

Let's just say we've been through this, and we are determined to get a rebreather. However, the purchase of a rebreather is contingent on qualifying as a Rebreather Diver. In this article, you will learn in detail what to focus on when choosing an instructor.","content":"**Rebreather instructors**\n\n[Rebreather](https://www.divesoft.com/en/products/ccr-liberty/philosophy) manufacturers, Divesoft not excluded, **offer their units through their instructors, who also provide divers with the necessary training for basic qualifications**. A rebreather diving course is always catered to the particular rebreather being used. If you are already a rebreather diver, you must at least go through a crossover for the new type of rebreather, as each rebreather has critical specifics components. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/79bd32fea081d75a8203c03920f7bfd30594f098_26-blog-instructors-1.png)\n\nDevices differ in their assembly, and **it is critical to know the specific assembly procedure to safely dive the unit**. However, the instruments also operate differently underwater between units, and it is necessary to become thoroughly familiar with this under the supervision of an experienced instructor.\n\nDivers who are completely **new to rebreathers need full training to bring them into a whole new world of knowledge, skills, habits, and mindset**. We begin this search by researching the manufacturer and this starts at their website, which typically includes [a list of their instructors](https://www.divesoft.com/en/instructors) for the particular unit (such as Divesoft). \n\nGood manufacturers take pride in their reputation, thus they also take care to **maintain high quality instructors**, so such a list should guarantee that the candidate will not make a bad choice. However, even among these instructors there are of course differences. \n\n**Criteria you should consider**\n\nThe first criterion for selecting an instructor will be the location and distance willing to travel for the course. This will narrow down my choice considerably. **Some training systems have their training materials worked out better than others and provide much better support for both students and instructors**, so this criterion can also be a deciding factor. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/80edf61947bf52212a0e201dabe791c6bf7dcdf4_26-blog-instructors-2.png)\n\nHowever, I personally advocate that the qualities of the instructor themselves matter more than the flag they work under. So, if we have already chosen a particular instructor, it is a good idea to get some references. **How long he has been teaching, how often he teaches, how much he is involved in his own projects and diving for his own pleasure.** Instructors who are really dedicated to rebreather diving do up to ten to twenty rebreather courses a year, some even more. This keeps their skills constantly sharp, and they don't lose necessary habits and contact with their students. \n\nOn the other hand, if they aren't diving for themselves, they are unable to maintain perspective and develop the necessary overlap of experience. **Instructors who teach even less frequently, but regularly have tw

2o or three courses a year and are fully committed to their own development are also a very good choice**. You will certainly be pleased if such an instructor can answer your questions using his or her own wealth of experience gained through a rich, broad and growing practice. Some manufacturers try to maintain a list of instructors just as instructors are active, and if they have not done any training for a long time, they are dropped from the list. \n\nIt is very helpful if you can get information on how dutifully the instructor teaches. A properly executed [rebreather diving course](https://www.divesoft.com/en/blog/what-will-i-learn-in-a-rebreather-course) is challenging for instructors, and it is in your interest to be sure that for the money invested you are not just getting a plastic card, but a good load of knowledge and skills that the instructor will impart through intensive training.\n\n* [Jakub Å imánek](https://www.divesoft.com/en/about-us/jakub-simanek), Divesoft Factory IT","showTags":false,"showDate":true,"image":{"mimetype":"image/png","size":1415527,"hash":"dec953f8b514f7314fd854fee74a835eb2607e16","id":"cl1q90wd1uia407763esx6u0b","filename":"26-blog-instructors.png","category":"divesoft/","type":"image"}},"id":"#7","type":"component","lock":false,"position":0},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#9","type":"component","lock":false,"position":1}],"id":"#0","type":"container","lock":false,"position":1},{"content":[{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#3","type":"component","lock":false,"position":0}],"id":"#1","type":"container","lock":true,"position":2}],"id":"root","idBuffer":"#10","lastCommit":"58c1ff5c-e011-4ac2-8b27-e0d0be2315c3","lock":true}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:cl1q88oulekcv0858u1rmasnr.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cl1q88oulekcv0858u1rmasnr.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cl1q88oulekcv0858u1rmasnr.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:cl1q88oulekcv0858u1rmasnr.annotations.0":{"key":"perex","value":"In previous articles we have discussed what a rebreather is, and the steps that lead to becoming a rebreather diver.

Our co-founder Aleš Procháska answers questions about how this testing device works.","content":"**What exactly happens to the Liberty during testing?**\n\nWe simulate the diving environment in our [Divesoft lab](https://www.divesoft.com/en/blog/divesoft-lab). The diver is replaced by instruments in these unmanned tests. A stainless steel mannequin, called Iron Man, carries the [rebreather](https://www.divesoft.com/en/products/ccr-liberty/philosophy) on his back. He breathes through \"artificial lung\", a computer-controlled breathing simulator that can simulate different breathing rates, depths of inhalation, and the flow of the breathing cycle. \n\nAnother device simulates oxygen consumption and carbon dioxide exhaled. **A rebreather is submerged in water whose temperature can simulate conditions from the Arctic to the Persian Gulf.** The water is in a massive chamber that pressurizes to simulate depths approximating 300 feet - and in fact, we went a little further in designing it to reach the magical 1,000-foot milestone.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/cff8819d301e6ccda5ab0bfe5c919e188b1a5d56_27-blog-bertha-1.png)\n\n**What does it measure?**\n\nThe basic measurement that most users are interested in is the work of breathing, which quantifies the ease of breathing with the rebreather. This is important both for the comfort of the diver, but **most importantly, if the work of breathing is able to avoid any CO2 retention at extreme depths during increased exertion combined with high gas density**.\n\nThe second key parameter is the endurance of the scrubber, how long it can absorb exhaled carbon dioxide before the CO2 concentration rises above the permissible limit.\n\nIn addition to these parameters, \"Big Bertha\" measures the hydrostatic imbalance, which shows how the breathing resistance changes when the diver is upside down or perhaps in the supine position. Also, the ability of the device to maintain the oxygen level without any fluctuations. Monitoring of where the water that condensates from the exhaled moisture goes, the characteristics of the pressure relief valve and the automatic diluent delivery, the temperature of the inhaled mixture, or whether some of the exhaled air remains in the mouthpiece until the next breath. Big Bertha gives Divesoft the ability to create a detailed analysis of the functionality and performance of the Liberty rebreather.\n\n**What conditions are rebreathers tested for?**\n\nThe standard test conditions for a rebreather are **a depth of 100 meters, a water temperature of 4°C, and a carbon dioxide exhalation rate of 1.6 liters per minute**, which corresponds to the heavy exertion of the diver. No diver would be able to bear such a load for long, but the test equipment can withstand it for hours. \n\nThen there are other combinations of parameters used for different specific tests, but they always have one thing in common - **they exceed human capabilities to make sure that the [apparatus under test can handle any load that a real person can put it through](https://www.divesoft.com/en/blog/would-you-trust-your-life-to-a-machine)**.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/9cd43420a2d556834428cda138d0100044b3033e_27-blog-bertha-2.png)\n\n**How does Bertha allow for better testing?**\n\nDivers with rebreathers have long traveled beyond the 100-meter milestone and continue to dive at depths to which the devices have never been tested for. While the behavior of the device can be estimated from testing at shallower depths, **there are several non-linear dependencies, and until its performance is measured, it will always be a guess**. Therefore, Bertha was developed to measure and describe the behavior of a breathing apparatus at extreme depths, which was not possible before with previous equipment.\n\nThe second fundamental thing is accessibility. We have Bertha in-house, so **we can test the devices we are developing as often and as long as we like**. Although several laboratories can test rebreathers within a hundred or even two hundred meters, such testing is always lengthy.\n\n**What is the future vision for testing, are we going to improve it any further?**\n\nThe test facility built around Bertha is for research and development and is therefore constantly being improved to be able to **test even newly developed rebreather features.** Development will never be finished because we are constantly striving to innovate and introduce new ideas. With innovations and new ideas come new problems. We will need to always have the capacity to test our designs safely and effectively. Other improvements are being made to facilitate testing, for example, we are now completing the installation of a handling device that will allow the chamber to be opened and closed automatically. That is not an easy thing to do because the pressure vessel lid weighs 600 kilograms. Until now, we have been handling it with a crane, which can be time consuming.\n\nDo you have any questions about Big Bertha?

The system never locks out the diver; instead, the system will indicate the status of the unit in light of any damage if able to do so. When [cave diving](https://www.divesoft.com/en/blog/ccr-liberty-cave-diving-resistance), the inability to submerge can mean not being able to return from a dive; therefore, the CCR Liberty does not impede submersion.\n\nIt is always the user’s responsibility to decide whether he/she switches to a backup apparatus or chooses to begin a dive with a partially malfunctioning rebreather.\n\nA CCR Liberty user must accept the fact that diving involves risk. Following everything the user has learned by reading the CCR Liberty’s technical manual and during their training on the rebreather can only reduce the risk. Diver safety is increased through by regular training, methodical education, and following good diving practices. Diving with a rebreather requires a far greater degree of discipline and awareness compared to diving with an open-circuit apparatus.\n\nIf you do not accept this risk and you are not a trained, careful, and disciplined diver, do not dive with the CCR Liberty.\n\nThe manufacturer does not bear any responsibility for the use of the CCR Liberty if the apparatus has been modified in any way that is not stated in this manual or in the technical guidelines issued by the manufacturer.\n\n**Documentation**\n\n**Version**\n\nThe technical documents are subjected to a process of continual development and improvement.

You already know [how to choose an instructor for a rebreather course](https://www.divesoft.com/en/blog/how-to-choose-an-instructor-for-your-rebreather-course). If a student is to be well prepared to dive safely with a rebreather, such training, like OWD, should include a detailed theory section, pool training and open water diving. ","content":"The **theoretical section ranges from about 8 to 12 hours** where you will learn specific things about the operation of the device, its types and configurations, details on oxygen sensors, CO2 absorption, breathing work with the rebreather, etc. A very important chapter is of course physiology, which brings new contexts with [rebreather diving](https://www.divesoft.com/en/blog/7-steps-to-becoming-a-rebreather-diver), and it is necessary to be aware of new pitfalls thrown at the diver in the form of dangerous situations. \n\nWith a [rebreather](https://www.divesoft.com/en/products/ccr-liberty/philosophy), for example, you can easily get to physiological gas levels that are not at all common in open circuit diving. **Dive planning and gas management are also fundamentally different**. A good instructor will put all these new facts into a coherent context so that you understand the issues well. This is the only way you will be able to make the right decisions at important moments in the future. \n\nWe've already written about instrument set-up, but there's no harm in mentioning it again because it's a critical part of training. A properly assembled and well tested apparatus before the actual dive forms a keystone factor of a safe dive, and everyone needs to be able to operate it without hesitation.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/77646cb648a918b885078cb5ab33cac3eef1a10b_28-course.png)\n\n**Training in a pool or confined water** should give you a basic familiarity with how the apparatus behaves underwater. You will get a feel for it in a safe environment before venturing into open water. You will go through the most basic exercises and begin to learn the necessary habits. Usually, one training session in the pool is enough, but some training systems g

2ive even more attention to this part.\n\nThe core part of training, as with any other course, is training in a real open water environment to gain real experience. Given the wide range of skills a diver must qualify, **a good course should include a minimum of 8 dives of 40 - 60 minutes duration.** Anything less is insufficient. \n\nDuring this training you will learn to operate the unit in detail underwater. Controlling buoyancy or maintaining optimum loop volume will be new skills. You will get the drill of closing the mouthpiece every time you take it out of your mouth into your muscle memory. The mask won't be the only thing you'll be able to pour water out of underwater because you'll learn how to pour water out of the breathing circuit as well. This and many more such exercises will prepare you for common rebreather diving situations. **It would not be a good course if it does not also prepare you for emergency and risky situations.** You will learn the procedures for dealing with failures or unexpected events such as high and low partial pressure of oxygen, hypercapnia and so on. \n\nI dare say that **after completing the rebreather course you will leave as a new diver**. You will learn during the course that you cannot approach a rebreather in the same way as conventional open circuit, because it simply works on a different principle. \n\nWhen you encounter an obstacle underwater, you'd rather swim around it than swim over it in one mighty breath and exhale to return to the original depth. You will already understand that, unlike the open circuit, ascending to the surface can make situations worse and that you have much more time to solve the problem underwater.\n\n* [Jakub Å imánek](https://www.divesoft.com/en/about-us/jakub-simanek), Divesoft Factory IT","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":1606402,"hash":"ba566f77f12fb99d5df6fa7673266efe470d4c3b","id":"cl2ypxyvb5rmm0776ilpm8xr0","filename":"28-course-2.png","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#4","type":"component","lock":false,"position":2},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":4}],"id":"root","idBuffer":"#5","lastCommit":"a9a1770e-be55-45b8-a0d9-d3fe1c745f6c"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:cl2ypayw6idsr0858lt8r4u8f.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cl2ypayw6idsr0858lt8r4u8f.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cl2ypayw6idsr0858lt8r4u8f.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:cl2ypayw6idsr0858lt8r4u8f.annotations.0":{"key":"title","value":"What will I learn in a rebreather course","__typename":"PageAnnotation"},"PageTranslation:cl2ypayw6idsr0858lt8r4u8f.annotations.1":{"key":"perex","value":"Let's face it, entering the rebreather world is the start of something new.

These plugs are designed to act as a spacer so that the user can remove the high-fidelity sensors. The Divesoft helium sensors are highly sensitive to moisture and can be easily corrupted if the moisture is not removed through proper ventilation. \n\nThe purpose of these plugs is so that the helium sensors can be removed when the user is not diving with a helium mix. It is recommended that when the user is not diving with a helium gas mixture the user should use the helium blind plugs instead.\n\nTo install the Blind plugs:\n\n- First, take a hex key and remove the oxygen cells block.\n- Once the block is removed then take hex key and remove the hex screw within helium sensor securing sensor to Liberty head.\n - After screw is completely removed then firmly grasp helium sensor and gently remove sensor, take care as to not twist sensor upon removal.\n- Then install the blind plug in the identical orientation as the helium sensor then secure with a hex screw, always be sure to use **only two fingers** for tightening screw and **do not over tighten screws**.\n- Repeat this process for opposite side helium sensor.\n- Once both blind plugs are installed and hex screws properly secured then reinstall oxygen cells block, take care as to not over-tighten any screws.\n- Place helium sensors in a labeled small bag and properly store them in a climate controlled area to use best practices for your rebreather sensors. They are designed for extreme conditions of rebreather diving, but in order to guarantee their life, they must be properly cared for.\n- During your predive operations when using the blind plugs, the Liberty will show an error – sensor missing.

This is expected and will not have any effect on diving operations.\n- If diving with trimix or other helium based mixtures, it is highly recommended that the Blind plugs be removed.

The D-rings should be high enough for you to reach the left ring with your left thumb and the right ring with your right thumb.

Depth is calculated from measured hydrostatic pressure. Fresh water (default) or seawater density can be set for the depth calculation (units and salinity are set in Setup → Preferences).\n\nSetting fresh/sea water does not affect decompression calculations. Decompression is based on ambient pressure and is independent of the displayed depth.\n\n**No deco**\n\nYou can stay for the indicated time at the current depth, breathing the current mixture (current He content and current SP), to avoid a decompression obligation. It is, however, presumed that the diver will follow the recommended ascent rate.\n\nDuring the dive, there is a situation where the No Deco indicator already shows a zero value, but the decompression ceiling value is still not displayed. Such a situation can last for tens of seconds. The scenario is due to the fact that the No deco time has ended and the decompression ceiling is below the surface level, but its value is so low that there is no need for staged decompression as a free ascent is advised.\n\n**Ceiling**\n\nThe depth of the decompression ceiling decreases continuously up to the surface. The stops displayed are never random. Always stay below the depth of the ceiling, even if the ceiling depth is very shallow.\n\nThe ceiling indicator in the Liberty replaces the indicator of decompression stops. The diver selects the depth at which they do the decompression stop or steadily ascends in accordance to the decompression ceiling. This approach may be more effective in terms of decompression time. Time reference is TTS (Time To Surface). Do not follow the decompression ceiling at low depths if conditions do not permit it. Waves, currents, positive lift of gear at a shallow depth, no visual reference, and other factors can cause uncontrolled ascent above the ceiling or completely hinder decompression at this level.\n\nAscending above the ceiling generates a warning. A further violation of more than 1 m (3 ft), leads to an additional alarm. Both alarms are logged. The decompression calculation will continue without a penalization. The diver is responsible to decide how to minimize the probability of severe consequences.\n\nDecompression is no longer required when the ceiling value disappears.

Measured ppO<sub>2</sub> is adjusted according to the mathematical model of the breathing loop. The calculation of O<sub>2</sub> delivery and possible subsequent opening of the solenoid is performed at six-second intervals. Oxygen is added alternately using the solenoids corresponding to both control units.\n\nIn the event that it is not possible to determine the actual depth (due to a malfunction or manual exclusion of all pressure sensors), regulation of oxygen delivery switches to a 

2simple algorithm.\n\n**Setpoint**\n\nThe setpoint is a required ppO<sub>2</sub> value; for information on adjusting the setpoint, see section 2.4.2 Setpoints. Two special values, “low setpoint” and “high setpoint” are fixed. These can be selected simply by a long press of the upper key (for the high setpoint) or lower key (for the low setpoint).\n\nIn the default setting, the low setpoint has the value of 0.7 bar (70 kPa). It is possible to reset it within the range of 0.4 to 1.3 bar.\n\nIn the standard setting, the high setpoint has the value of 1.3 bar (130 kPa). It is possible to reset it within the range of 0.7 to 1.6 bar.\n\nUpon starting the CCR dive mode, the low setpoint is activated by default.\n\n**Descent setpoint**\n\nThe descent setpoint is designed for situations when the diver needs to rapidly descend to a given depth, for example, when diving in a current. The utilized algorithm uses the natural rise of ppO<sub>2</sub> during descent. It is necessary to descend rapidly; the natural rise of ppO<sub>2</sub> has to be faster than the oxygen consumption.\n\nUse of the descent setpoint must be enabled in the configuration.\n\nIf it is enabled, the descent setpoint is automatically activated when switching from surface mode to CCR mode. It cannot be activated in another way. The descent setpoint has a variable value. The initial set value gives the ppO<sub>2</sub> on the surface. At depth, the current setpoint increases linearly by 0.2 bar (20 kPa) for every 10 m of depth (i.e. it increases by the same absolute values as when diving with an open circuit with air, only with a different initial value).\n\nThe descent setpoint is automatically switched to the low setpoint upon reaching that value or upon completing or significantly slowing down the descent, but no later than after ten minutes.\n\nWhen using the descent setpoint, the user must continuously check whether he/she has reached or exceeded the maximum physiologically permissible ppO<sub>2</sub> limit and adjust the rate of descent accordingly, or take other measures.\n\nDescent setpoint can be re-enabled by key shortcut or from the Setpoint menu (if we are at an applicable depth).\

2n\nIf On+Sfc is set in Setup / Setpoints / then the descent setpoint at the surface will never timeout.\n\n**<span style=\"color:red\">WARNING: if the initial Descent SP value is lower than the set threshold for the Low ppO<sub>2</sub> alarm, then while the Descent SP is active it will only alarm if it reaches 0.05bar less than the current Descent SP value - this is especially true at depths shallower than 6m when the Descent SP is set to 0.2bar (at the surface) and the default Low ppO<sub>2</sub> alarm is 0.3bar.</span>**\n\n**Setpoint limitation**\n\nBesides the set value, the setpoint limit is defined by the ambient pressure. For example, at a depth of 3 m, where the hydrostatic pressure is 1.3 bars, ppO<sub>2</sub> can reach a maximum of 1.3 bar when using pure oxygen.\n\nSince obtaining a presice 100% of oxygen in the loop is not always practical, the setpoint is set at 90% of the ambient pressure by default. This value can be reset within the range from 60% to 96%.\n\n**Emergency ppO<sub>2</sub> control**\n\nIf all chemical sensors are not valid (error, disabled etc.), the depth is < 6m/20ft, and the ppO<sub>2</sub> source is form O<sub>2</sub> sensors, an emergency O<sub>2</sub> injection + alarm is done every 6s.\n \nThe unit assumes that in a depth lower than six meters the risk of hypoxia is greater than the risk of hyperoxia, and prevents the fatal consequences of dysfunctional or disabled sensors. In this case, the diver must not continue his/her descent until the ppO<sub>2</sub> stabilizes and the diver is sure of the breathing mixture.\n\n**Emergency ppO<sub>2</sub> control by indirect measuring with He sensors**\n\nIf all chemical sensors fail in dive mode, an alarm “pO<sub>2</sub> measuring lost” is brought up.\n\nIndirect measurement of ppO<sub>2</sub> using helium sensors can only be activated manually, provided that the helium measurement setting is switched on (TMX only) and the helium fraction in the diluent is greater than 20%. When using indirect oxygen measurement with helium sensors, always be sure that helium sensors are calibrated and functional.\n\nFor indirect oxygen measurements, all fields displayed with ppO<sub>2</sub> are blue.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#204","type":"component","lock":false,"position":135},{"name":"Divider","data":{"color":"darkGray"},"id":"#205","type":"component","lock":false,"position":136},{"name":"SectionDivider","data":{"title":"2.6.4 Decompression"},"id":"#526","type":"component","lock":false,"position":137},{"name":"TextBlock","data":{"text":"### <span id=\"2-.-6-.-4-Decompression\">**2.6.4 Decompression**</span>\n\nThe decompression algorithm takes measured ppO<sub>2</sub> values and inert gases according to the set diluent composition into account.\n\nDuring a dive, the safety level can be set in the menu by switching the set of standard and bailout gradient factors (GFs) without affecting the mode in which the CCR Liberty is operating.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#206","type":"component","lock":false,"position":138},{"name":"Divider","data":{"color":"darkGray"},"id":"#207","type":"component","lock":false,"position":139},{"name":"SectionDivider","data":{"title":"2.6.5 Specific handset control"},"id":"#527","type":"component","lock":false,"position":140},{"name":"TextBlock","data":{"text":"### <span id=\"2-.-6-.-5-Specific-handset-control\">**2.6.5 Specific handset control**</span>\n\nLong press upper key — next higher setpoint\n\nLong press lower key — next lower setpoint\n\nIf Descent SP and Deco SP are enabled in the settings, switching with key shortcuts also takes place between them.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#208","type":"component","lock":false,"position":141},{"name":"Divider","data":{"color":"darkGray"},"id":"#209","type":"component","lock":false,"position":142},{"name":"SectionDivider","data":{"title":"2.7 Manual CCR mode"},"id":"#528","type":"component","lock":false,"position":143},{"name":"TextBlock","data":{"text":"### <span id=\"2-.-7-Manual-CCR-mode\">**2.7 Manual CCR mode**</span>\n\nThis mode serves primarily for training","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#530","type":"component","lock":false,"position":144},{"name":"SectionDivider","data":{"title":"2.7.1 Entering manual CCR mode"},"id":"#529","type":"component","lock":false,"position":145},{"name":"TextBlock","data":{"text":"### <span id=\"2-.-7-.-1-Entering-manual-CCR-mode\">**2.7.1 Entering manual CCR mode**</span>\n\nIt is possible to switch to manual CCR mode from the menu in CCR mode, bailout OC mode, or surface mode.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"},"mimetype":"image/png","size":284331,"hash":"302d44c8c131c82b67f9f11ccb6698f96b630887","i

Allow the wind to remove the finest dust particles.\n\nIf you are working indoors, pour the sorbent into the cartridge from a minimal height. Sorbent dust is aggressive and can cause corrosion. Therefore, we do not recommend working with the scrubber inside of an automobile, for example.\n\nIn order to prevent the sorbent from falling into the central tube, place the canister’s metal disc lid over the opening, or plug it by other suitable means. Pour sorbent into the cartridge until it is approximately one-third full. Then gently lift the cartridge, and allow it to fall three times from a height of approximately 1 cm (1/2”). Repeat this process when the cartridge is two-thirds full and again when it is completely full. The cartridge is completely full when the sorbent reaches a level between the min and max lines marked on the central tube.\n\nAfter filling, place the metal disc and spring-loaded pressure plate on top of the sorbent. Then remove the pressure plate and lid, and verify that the surface of the sorbent is levelled and that no channels have formed. Place the metal disc and spring-loaded pressure plate on top of the sorbent again; press down and secure the assembly with the retaining ring. The retaining ring must fit into the slot on the pressure plate.\n\nIf the cartridge is not filled sufficiently, a gap of less than 6 mm or less will remain between the edge of the lid and edge of the metal mesh. In such a case, add sorbent and then shake and close the cartridge according to the procedure described above.\n\nIf the cartridge is overfilled, there will be a gap greater than 17 mm between the edge of the lid and the edge of the metal mesh, and it will not be possible to insert the retaining ring without excessive force. In such a case, remove the excess sorbent with a clean teaspoon or any other suitable tool. Shake the cartridge, and close the lid again.\n\n

2Before inserting the cartridge into the scrubber canister, check to ensure that the water trap is dry. If that is not the case, remove the water trap, and dry it with a towel.\n\n**After each scrubber change, the stack timer Menu / Predive / Stack time reset must be reset**\n\nThe stack timer measures the use of the scrubber by simply counting the time spent in the dive mode. You can adjust whether stack time is calculated on the surface or not.\n\nSorbent dust damages textiles, especially polyamide and cotton fabrics. Therefore, after working with the scrubber, immediately wash the towel on which the cartridge was placed and all clothing that was exposed to sorbent dust.\n\nDo not work with sorbent in the vicinity of load-bearing straps, ropes, or even metal mountain climbing or speleological equipment. In the event of possible exposure to sorbent, ropes and load-bearing straps should be discarded immediately, as their loading capacity can deteriorate significantly.\n\n**Condition of the scrubber before submersion**\n\nThe scrubber must have sufficient absorption capacity for the planned dive.\n\nThe sorbent must contain some amount moisture so that the chemical reactions that enable the scrubber to remove CO<sub>2</sub> from the breathing mixture can take place. This means that the scrubber cannot be completely dry or frozen.\n\nIn freezing weather, stow the rebreather in a warm space prior to the dive. If you are outside with the apparatus and a delay happens, maintain the temperature of the sorbent by breathing from the apparatus.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#346","type":"component","lock":false,"position":38},{"name":"Divider","data":{"color":"darkGray"},"id":"#347","type":"component","lock":false,"position":39},{"name":"SectionDivider","data":{"title":"3.2.2 Assembling the rebreather body"},"id":"#582","type":"component","lock":false,"position":40},{"name":"TextBlock","data":{"text":"### <span id=\"3-.-2-.-2-Assembling-the-rebreather-body\">**3.2.2 Assembling the rebreather body**</span>\n\nMount the head on the CO<sub>2</sub> scrubber canister.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#348","type":"component","lock":false,"position":41},{"name":"TextBlock","data":{"text":"When mounting the head, push the scrubber canister pin into the opening on the head, and close the head.\n\nPress on the head from above so that it is fully seated.

If you have not successfully completed such a course, leave mixture blending to a qualified person.\n\nWhen handling oxygen, follow the procedures and rules with which you were familiarized in a trimix course and, subsequently, in a CCR Liberty course. If you have not successfully completed such a course, do not handle the CCR Liberty.\n\n**3.2.5.1 Diluent**\n\nChoose a diluent that is able to flush a high oxygen mix from the breathing loop. Prepare the diluent so the partial pressure of oxygen will be 0,2 bar lower than the planned setpoint at the greatest depth of your planned dive. Partial pressure of nitrogen should not exceed 4 bar (3.2 bar is recommended).\nIn regards to oxygen compatibility and cleanliness for oxygen service of the parts working with diluent, do not exceed an oxygen concentration of 21% (± 1%) in the diluent. Minimum oxygen concentration is 5%.  \nDiluent contamination should not exceed the limits given by the standard EN12021:2014. Section 6.2 when using compressed air for the unit.\n\nMake sure that the diluent was filled by a compressor with properly maintained filters.   \n\nThe gas must meet the requirements of EN12021:2014\nAlternatively, you can use an personal filter. When using a compressor with a combustion engine, ensure that the exhaust gases from the engine cannot get into the compressor intake.  \n\nMixtures with higher helium present more advantages for a number of reasons. But a low O2 mix on the surface in shallow depths, with a lack of breathability, significantly increases risks.  \n\nAfter filling, write the mixture composition with a permanent marker on a label (piece of duct tape) and attach it to the cylinder.  \n\nThe consumption of diluent depends on the dive profile, frequency, and extent of depth changes. Diluent capacity is not limited by time but by the dive profile. This should be taken into account especially when planning dives in caves. Diluent is consumed mainly during the descent. During the ascent there is a zero theoretical consumption, and any practical consumption is mainly due to mask clearing.\nBased on a practical experience, the typical diluent consumption during a simple dive to a depth of 40 m is approximately 50 to 70 bar. This usually does not increase by staying longer at the same depth.  \n\nAlways keep a sufficient safety margin (at least 50 bar) to cover unplanned situations. If the pressure in the diluent cylinder is lower than 70 bar, not even a brief dive should not started.  \n\nAccording to the standards to which the CCR Liberty is CE certified and designated, do not dive to depths greater than 40 m. Therefore, the CCR Liberty is CE certified to 40 m.\n\n**Oxygen**\n\nUse oxygen intended for breathing. Oxygen contamination shall not exceed the limits given by the standard EN 12021 Section 6.2 vhen using compressed air for the unit.\n\nWe recommend using oxygen with a purity of at least 99.5%.\n\nOxygen consumption for gas duration calculations is 1.78 l/min according to the EN 14143:2014. When considering the initial cylinder pressure of 200 bar and a final pressure of 50 bar in the cylinder, the oxygen supply suffices for 253 minutes. In this calculation, oxygen contained in the diluent is not considered.\n\nThese conditions correspond to high levels of physical effort during a dive. If a diver is calm during a dive, consumption significantly decreases, and the quantity of oxygen and the sorbent service life is extended. A dive plan that relies on an entire dive being a low-effort dive is inaccurate.\n\nIn any case, an oxygen cylinder filled to 200 bar is sufficient for a dive, which greatly exceeds the duration of the CO<sub>2</sub> scrubber.\n \nIf the pressure in the oxygen cylinder is lower than 70 bar, not even a brief dive should be started.\n\nAccording to the valid technical standards, filling oxygen to an operating pressure greater than 200 bars is prohibited.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#359","type":"component","lock":false,"position":55},{"name":"Divider","data":{"color":"darkGray"},"id":"#360","type":"component","lock":false,"position":56},{"name":"SectionDivider","data":{"title":"3.2.6 Battery charging"},"id":"#586","type":"component","lock":false,"position":57},{"name":"TextBlock","data":{"text":"### <span id=\"3-.-2-.-6-Battery-charging\">**3.2.6 Battery charging**</span>\n\nBefore charging the batteries, remove the jumpers from the sockets.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#361","type":"component","lock":false,"position":58},{"name":"TextBlock","data":{"text":"We recommend charging the batteries to full c

A higher content of He results in less negative buoyancy, which makes transporting the cylinder under water more convenient.\n\nPreparation of the bailout stage cylinders is similar to that of open-circuit diving with trimix.

Detach the head, remove the scrubber cartridge, remove the water trap, and dry it with a paper towel. Use another paper towel, to dry the exterior surface of the cartridge.\n\nThe head should be left to dry to ensure proper functionality of the oxygen and helium sensors.

The purpose of regular cleaning and disinfection is to prevent the multiplication of these microbes to an extent that would pose a hazard to the user and to prevent the transmission of infection between various users.\n\nNo more than a week may pass from the first dive after disinfection until the next disinfection if the CCR Liberty is stored in a cool place. When storing the rebreather at a temperature higher than 25 °C, this interval decreases to four days; the weekly interval can be maintained only for the scrubber cartridge. It does not matter how many dives you undertake during the stated period.\n\nDisinfection is always necessary before changing users of the CCR Liberty. Never lend or borrow a rebreather that has not been disinfected! Transmission of infection can happen with a single inhalation. An infected user will not necessarily have any symptoms of infection.\n\nBegin cleaning by rinsing the assembled rebreather with clean fresh water. Disassemble the rebreather into its individual parts.\n\n**Procedure:**\n\n1. remove the ballast.\n2. unscrew and detach the oxygen and diluent cylinders, insert watertight stoppers in the regulator inlets.\n3. remove the HUD from the DSV.\n4. remove the breathing bags with corrugated hoses from the head.\n5. remove the ADV, manual valves, and overpressure valve from the breathing bags.\n6. detach the breathing bags from the harness.\n7. remove the head with the attached handsets and HUD.\n8. remove the CO<sub>2</sub> scrubber from the cartridge and dispose of it safely.\n9. remove the scrubber canister from the backplate, and remove the water trap.\n\nPut the head with the control units in a clean, cool, and dry place.\n\nPrepare the antiseptic solution in a suitable container, free of mechanical and chemical impurities. For example, a bathtub, mortar tub, or large Tupperware container is suitable for disinfection.\n\nFor ordinary disinfection, use a 0.5% concentrated Divesoft antiseptic. Follow the instructions when working with the antiseptic agent.\n\nRinse with clean fresh water and place the tube, water trap, corrugated hose assembly with an open DSV, breathing bags, and CO<sub>2</sub> filter in the tub. Manipulate the corrugated hose assembly and the DSV to expel air so that the antiseptic solution fills the entire space (this necessary skill is taught in the CCR Liberty training course). Completely fill the breathing bags with the antiseptic solution.\n\n

2If you notice mold growth, it is necessary to perform a thorough disinfection and surface cleaning. Most surfaces can be wiped with an antiseptic soaked rag. Use a bottle or tube brush to clean the inner surfaces of the corrugated hoses.\n\nLeave the parts in the antiseptic solution for one hour. Remove the parts when complete and rinse with clean fresh water, allowing them to dry afterwards. Do not dry the parts in direct sunlight.\n\nWhen more intensive disinfection is required, use a more concentrated solution (maximum 2%) or leave the parts in the antiseptic solution for a longer time (maximum four hours).\n\nInstead of Divesoft disinfection, one can use a different antiseptic agent based with quaternary ammonium salts that is compatible with the materials from which the CCR Liberty is made. The CCR Liberty’s manufacturer does not guarantee the compatibility of antiseptic agents other than Divesoft disinfectant. In any case do not use chlorine-based agents.\n\nIn normal circumstances, the head, ADV, manual bypass valves, and overpressure valve do not need to be disinfected.\n\nIf a more thorough disinfection is required, the oxygen sensors can be removed from the head, and the remaining parts can be washed with antiseptic solution. The ADV, manual bypass valves, and overpressure valve can be disinfected by submerging them in the antiseptic solution.\n\nThe antiseptic solution is highly toxic to aquatic organisms.

2If the CCR Liberty is stored in a dry and clean environment, do not connect the corrugated- hose assembly with the DSV to the head or to the breathing bags, and store the rebreather open. Dust occurs almost everywhere and is inevitable. Limit the accumulation of dust by, for example, covering the unit with a washed bed sheet.

If it is not necessary to completely jettison the ballast, try to attain buoyancy by first removing the ballast on the left side and then, if necessary, on the right side. Jettisoning the ballast on the left side helps to bring the dry-suit release valve and the compensator’s inflator in a better position for deflation.\n\nJettisoning ballast is a skill that, in addition to agility and mobility, requires training under the supervision of an instructor in a CCR Liberty diving course.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#523","type":"component","lock":false,"position":238},{"name":"Divider","data":{"color":"darkGray"},"id":"#519","type":"component","lock":false,"position":239},{"name":"SectionDivider","data":{"title":"3.6.8 Rescue on the surface"},"id":"#638","type":"component","lock":false,"position":240},{"name":"TextBlock","data":{"text":"### <span id=\"3-.-6-.-8-Rescue-on-the-surface\">**3.6.8 Rescue on the surface**</span>\n\nWhen assisting an injured CCR Liberty user on the surface, it is possible to increase buoyancy by jettisoning the ballast.\n\nEven if the diver’s life is in serious danger, and it would be necessary to remove all equipment during the rescue, buoyancy should be ensured by closing the DSV, inflating the compensator wings, and jettisoning the ballast.

Of course, sensors can suddenly reach the end of their service life even during a dive, especially in an environment with a high partial pressure of oxygen. Therefore, we recommend replacing the sensors no later than one year after putting them into operation or 18 months max after their date of manufacture.\n\nHowever, despite good handling, the sensors may, exhibit deviations or limitations even during their recommended life. For this reason, we recommend using the DIVESOFT Oxygen sensor tester kit regularly to test the linearity of the sensors. It is the only accurate and safe way to detect a faulty or limited sensor.\n\nIt is not necessary to discard replaced sensors. Even though a sensor’s degree of wear prevents it from reliably measuring higher partial pressures of oxygen in the rebreather, it is often usefull for measuring lower partial pressures of oxygen when preparing mixtures.\n\n**Hoses**\n\nIf any hose shows signs of excessive wear or if damage is detected during a bubble check (see chapter 3.4.8 In-water check), replace it. Hoses should be replaced during annual inspection from normal wear and tear.\n\nThe service life of the hoses is five years max from the time they were first used and seven years max from their production date.\n\n**Straps**\n\nThe harness straps are highly durable. A strap that has been damaged on the edge should only be replaced if it was cut more than one-third of its width.\n\nStraps are generally replaced for aesthetic reasons. You can order a replacement when ordering a regular service inspection.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#536","type":"component","lock":false,"position":260},{"name":"Divider","data":{"color":"darkGray"},"id":"#678","type":"component","lock":false,"position":261},{"name":"SectionDivider","data":{"title":"3.7.5 Oxygen Sensor Block Maintenance Instructions","skipToC":false},"id":"#679","type":"component","lock":false,"position":262},{"name":"TextBlock","data":{"text":"### **3.7.5 Oxygen Sensor Block Maintenance Instructions**\nProper maintenance of the oxygen sensor block is crucial for extending the lifespan of the sensor wiring and ensuring accurate oxygen readings.

If you are also transporting a supply of sorbent, it must be in the original packaging or in an appropriately sturdy and airtight container. Familiarize yourself with the regulations concerning the air transport of sorbent. Consider the possibility of purchasing sorbent at your destination.\n\n**Head**\n\nFor the purposes of air transport, the batteries must be disconnected by removing or turning the battery jumpers.

But there is not just one rebreather, there are several fundamentally different types of Closed-Circuit Rebreather (CCR) and Semi-Closed Circuit Rebreather (SCR). So, let's review the basic principles of rebreathers that are used in recreational and professional diving.  \n\n<h2>There are 5 types of rebreathers plus one extra:</h2>\n\n* O2 CCR\n* SCR\n* PSCR\n* mCCR\n* eCCR\n\nI consider all types to be proof of human ingenuity, but each of them has its own strengths, but of course also weaknesses. Let's focus on a basic understanding of the different principles, from the simplest to the most complex, and derive the advantages and disadvantages from there. \n\nFinally, **we will then show one solution that tries to use the most advantages with the least disadvantages**.\n\nSo let's take a look at how rebreathers work.\n\n<h2>O2 CCR</h2>\n\nThe oxygen closed circuit is** an ingeniously simple principle at first glance** and is actually the first ever independent breathing apparatus. \n\nAll we need to construct it is an oxygen source, which we inject into the breathing circuit via a demand valve sometimes supplemented by a constant flow nozzle, and a carbon dioxide scrubber to remove CO2 from the exhaled gas. For this, one or two counterlungs are sufficient to give the diver something to breathe from and a mouthpiece with directional valves to direct the flow of the breathing gas. In this way the device can operate without any electronics, virtually without the need to know the oxygen content of the loop, because if the device is well flushed with oxygen at the surface, the oxygen content of the breathing loop will always be very high during use. \n\nBecause the instrument uses only oxygen, it is the only unit that does not have to vent a single bubble, even at the ascent, where all other units must purge the excess gas volume.** Oxygen can be metabolized, so if you surface slowly enough, your body can process all the excess oxygen**. \n\nThe maximum compactness and very lightweight construction make it **easy to transport on dry land**, so it can also be used in areas other than diving. Such devices are used, for example, by firefighters, mine rescuers, pilots, etc.\n\nRecreational diving with an oxygen CCR is unfortunately very limited to a **maximum dive depth of 6 metres due to oxygen toxicity**. Even so, it can still be great for photography in shallow water, exploring mountain lakes and otherwise inaccessible places where we have to carry the device on our backs.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/22cdcde6607027fc9c9cfe83098bc28b86637d84_oxygen-ccr.png)\n*Oxygen Closed Circuit Rebreather – 1 In

So, we will use a very similar principle to the oxygen CCR, but **instead of oxygen we will add NITROX**. This will be injected into the circuit through a constant flow nozzle so that the oxygen consumed is always replaced by the oxygen from the nitrox. Since we metabolize the oxygen, but cannot metabolize the nitrogen in the nitrox, **we must get rid of the ever-increasing nitrogen by venting some of the gas out of the circuit.** Hence the semi-closed circuit. The simplicity of the design has been preserved, but the opportunity to go deeper has been traded off for a not very high gas consumption efficiency. \n\nBecause we consume oxygen, the fraction of oxygen in the breathing circuit will always be less than that in the cylinder with the supplied gas. How much smaller it will be depending on how much oxygen we consume. If we are at rest we use about 0.6 litres, but on exertion we may use 2.5 to 3 litres of oxygen per minute. In the case of a lower value, a flow rate of 8 litres of Nitrox 36 per minute would be sufficient to maintain breathable gas, but we have to allow for the worst-case scenario of never dropping below breathable levels. In that case, we need up to 18 litres per minute. \n\nThis is already like an open circuit, however, unlike an open circuit, **this flow rate can remain constant for any achievable depth**. In this particular case, **the maximum is 35 metres**. This means that the SCR is still up to tens of litres per minute better than the open circuit.\n\nThe unstable oxygen consumption also leads to an unstable gas composition in the breathing loop. **More consumption means less oxygen and thus the need for longer decompression**. PO2 naturally varies with depth, so the best mixture is out of the question. This is another disadvantage. Without an oxygen sensor connected, the diver cannot be sure of what he is breathing and how to calculate decompression, so he has to start from worst-case scenarios for both maximum depth and decompression calculations. We can also consider the fact that we cannot fill the cylinders with available air as a disadvantage. Or we could, but then we couldn't dive directly from the surface because the partial pressure of oxygen would be too low.\n\nDespite some drawbacks, however, the** Constant Flow SCR is very simple to operate,** which is why this principle was used in the first recreational rebreathers. It has also been dusted off in the recent past and in a somewhat hybrid form combined with electronics is used in one of the recreational rebreathers of the current day.\n\n![Diagram of how the semi-closed circuit rebreather works](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/b71ad6e8094fc41209081906cea6eb0dec18c625_scr.png)\n*Semi-closed Circuit Rebreather – 1 In

Everyone wants to know how this rebreather works. The word passive means that the mixture does not flow into the breathing circuit in a constant flow of gas but is injected by an ingenious mechanism every xth breath. Usually, every eighth or ninth breath. \n\nThe so-called breath keying is solved by t**he diver exhaling through a CO2 absorber partly into a large counterlung in the form of a bellows, and partly into a small counterlung**, which is placed inside the large one. Importantly, the small counterlung is separated from the large counterlung by a one-way valve, so that exhalation can be directed into it, but inhalation cannot be taken from it. Instead, when the diver inhales, it collapses along with the large counterlung as the diver sucks the gas out of the large counterlung, and with its other end with a second non-return valve, exhausts some of the gas into the surrounding environment. \n\nBy venting some of the gas to the surrounding environment, both counterlungs gradually shrink until they collapse completely. At that point, the diver can no longer breathe from the closed circuit, so the demand valve (essentially the second stage of the regulator) opens to supply the diver with a completely fresh mixture. With the exhalation, the counterlung fills and the whole cycle starts again. **The ratio of breaths from the closed circuit to the addition of fresh gas determines the ratio of the volumes of the two counterlungs.** As I mentioned above, the ratio is most often 8:1 or 9:1.\n\nThis system is actually very clever and retains a completely mechanical solution without the need for any electronics. It was and is therefore used for long and difficult cave explorations even at great depths. However, the mixture ratio in the loop and thus the partial pressure of oxygen is very unstable, and again always slightly lower than the oxygen content of the supply bottle. \n\nThe big disadvantage is **the inefficiency of decompression**, because you always have worse gas than in an open circuit, and the PO2 changes with depth, and breathing. Of course, the biggest disadvantage of all is the poor work of breathing, which comes from the counterlung placement usually very far from the diver's lungs. So any change in the diver's position will immediately have a negative effect on inspiratory or expiratory resistance. \n\nThe keying of the inspiration also means that the consumption, although lower than in an open circuit, increases proportionally with depth, as in an open circuit. \n\n![Diagram of how the passive addition semi-closed circuit rebreather works](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/b91883e904813d19ca5a54ff312b2991a4cd3727_pscr-1.png)\n*Passive Addition Semi-closed Circuit Rebreather – 1 In

However, in order to dive deep, we need to dilute the oxygen. This time, however, we do it by **leaving the oxygen alone and diluting it with another gas containing an inert gas** (nitrogen, helium). This gas could be air, trimix or even heliox. \n\n**The oxygen is injected into the circuit by means of a solenoid** (electro-magnetically controlled valve). The computer evaluates how much oxygen needs to be injected based on information from the oxygen sensors. The oxygen sensors react to the partial pressure by changing the electric current. The gas is diluted during descent by the previously mentioned diluent gas, which is injected by an automatic (mechanical) valve. **The computer adjusts the consumed oxygen to a pre-set oxygen partial pressure level** - setpoint. Therefore it is also referred to as Constant PO2 CCR.\n\nFrom the above, it follows that **the diver receives only the best mixture at any depth**. This achieves maximum gas consumption efficiency while minimizing decompression. See previous article (link) for details.\n\nDespite all the advantages and convenience of electronics that can also calculate decompression on-line, **the vulnerable point of such devices tends to be the faulty electronic components**. While today's electronics are of course at a different level than 40 years ago, the issue of oxygen sensors remains the same. Each eCCR has at least 3 sensors for comparing their readings and possibly identifying a faulty sensor.\n\nHowever, the other elements of the system are often not backed up, and in the event of their failure, the diver is forced to use emergency procedures.\n\n![Diagram of how the electronically controlled closed circuit rebreather (eCCR) works](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/62fd4235d5a841f8f324e5650de5e53054d1be71_eccr.png)\n*Electronically controlled Closed Circuit Rebreather (eCCR) – 1 Inhale counterlung; 2 Dive/Surface valve (DSV); 3 Exhale Counterlung; 4 CO2 scrubber; 5 Oxygen supply; 6 Oxygen reduction valve; 8 Oxygen Manual addition valve (MAV); 9 Oxygen SPG; 10 Diluent supply, 11 Diluent reduction valve; 12 Diluent SPG; 13 Automatic Diluent Valve; 14 Diluent Manual Addition Valve (MAV); 15 Oxygen sensors; 16 Control unit (CU); 17 Solenoid; 18 Handset display.*\n\n<div class=\"row\">\n  <div class=\"column\" >\n\t\t<p><b>Advantages:</b>\n\t\t<ul>\n\t\t\t<li>Maximum gas efficiency\n\t\t\t<li>Minimal decompression\n\t\t\t<li>Constant and known partial pressure </br>of oxygen in the loop\n\t\t\t<li>Maximum depth range\n\t\t</ul></p>\n\t</div>\n\t\n  <div class=\"column\">\n\t<p><b>Disadvantages:</b>\n\t<ul>\n\t\t<li>Electronics can fail\n\t\t<li>Complexity of equipment\n\t</ul></p>\n</div>\n</div>\n\n<h2>mCCR</h2>\n\nThe trend to avoid electronics at all costs, but still enjoy the benefits of a fully closed circuit, such as maximum gas savings and minimum decompression, has led to the design of the mechanical CCR (mCCR). \n\nThis has been achieved by retaining the eCCR design but** instead of a solenoid, oxygen is injected through a constant mass flow**. The oxygen flow is achieved by a nozzle connected to a constant intermediate pressure. This means that the first stage of the oxygen regulator has a blanked section which registers ambient pressure. The ambient pressure therefore does not affect the intermediate pressure and so the oxygen flow through the nozzle decreases with increasing ambient pressure and therefore gas density. However, the amount of oxygen molecules that pass through the nozzle is independent of depth, so the oxygen flow still affects PO2 in the same way. \n\nSounds fantastic, doesn't it? Except that to keep oxygen from accumulating too much in the breathing loop, w**e have to set the oxygen flow rate lower than our metabolic consumption in order to maintain breathable gas.** This creates the need to inject oxygen manually. Thus, our oxygen is measured by the same sensors as in the case of eCCR, but everything is **monitored and controlled by the fallible human brain**, which is easily distracted. Not adding oxygen, especially during ascent to the surface, would of course have fatal consequences.\n\nA blinded first stage on oxygen is a very clever solution, but it comes with one drawback. The fact that **the mean pressure does not vary with depth implies that when the mean pressure equalizes with the ambient pressure, oxygen stops flowing altogether**. Further, it is not even possible to use separate manual injectors. mCCR is therefore limited by depth.\n\n![Diagram of how the manual closed circuit rebreather (mCCR) works](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/f406683e3a0020707c92f047820af8aa847badc1_mccr.png)\n*Manual Closed Circuit Rebreather (mCCR) – 1 In

This is clear. But what to do about it? We have thought about this too, and the solution we bring is that we can't do without electronics in this case. **We also have to give up maximum simplicity.** But what if by making the system more complex, or rather, by backing it up and securing it, we achieve greater security than with a simple system?\n\nWe know this from advanced technologies on which human lives depend, such as aerospace. **All systems are minimally duplicated or triplicated and ingeniously put together to complement or replace each other.** We have attempted the same in the case of the [Liberty CCR](https://www.divesoft.com/en/products/ccr-liberty) which we dare to call **the Fault Tolerant Rebreather**.\n\nIf we build two systems side by side, each with its own power source, its own set of sensors and its own solenoid, then everything is duplicated. In addition, if we interconnect the two systems so that they can communicate with each other continuously, sharing information from all sensors and evaluating it independently, then we achieve that **the failure of one or more components will not affect the operation of the entire system**. \n\nThe instrument can continue to operate without the need for any emergency diver intervention. **The diver, on the other hand, has maximum control of the situation**. He knows the readings from all the sensors and can evaluate or directly verify the accuracy of their readings. \n\nThe smart software also makes sure that the handling of this already quite complex device is user-friendly and the diver has as much or much less work to do with controlling the device than with conventional eCCRs.\n\nThe only disadvantage is the relative overall design complexity of the device, which is for the better and makes the diver's life rather easier.\n\n![Diagram of how the fault tolerant electronically controlled closed circuit rebreather works](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/f8eefd171569f4bd2d86861570dcd1a45c84759f_fault-tolerant.png)\n*Fault tolerant electronically controlled Closed Circuit Rebreather – 1 In

Secure the connector in the head with the two\nenclosed screws using a 3 mm Allen key.\n\nWrap the ODA cable around the corrugated hose so that it does not form excess loops and is\nnot too short that head movements are restricted.\n\n**IMPORTANT: ODA needs to be enabled in Preferences in order to power on**. On the handset in the main\nmenu, select Setup / Preferences / Indication. For Left and Right, Buddy D., HUD, ODA, and None\nare selected.

ODA can be\ninstalled on both the left and right eye, which is a matter of personal preference.\n\nEveryone has their dominant eye, which they perceive more naturally. The dominant eye can\nbe independent of whether you are right-handed or left-handed. If you do not know which is\nyour dominant eye, try which position of ODA suits you better and you feel more natural and\ncomfortable when watching it.\n\nIf you need to replace the ODA location side, you must unscrew the top hinge securing the ODA\nand screw it to the opposite side of the holder’s arm.\n\nIf necessary, you can flip the ODA display. Go to Setup / Preferences / Indication / HUD screen right/\nleft.\n\nAdjust the position of the ODA so that it is in your field of view and at the same time does not\nexcessively obstruct the view and does not collide with your diving mask. Pay close attention\nto the setting of the ODA angle to your eye. The angle has a major effect on the display of the\nentire ODA display.\n\nThe distance of the eyepiece from the eye should be approximately 4

Inverted\nconnection can cause serious injury or death.\n\nCheck that the directional valves are not visibly damaged and attach the appropriate\nconnections to the BOV. In the case of integrated MAVs, set the MAV position towards the front\nof the BOV so that it is pointing downwards (the closest possible position for the connection\nof the middle pressure connection of the 2nd stage and the adjustment screw). You get an\nergonomic position for controlling manual valves.\n\nSecure the connections with retaining rings. **The retaining rings must be securely sitting along\nthe entire length of the groove.**\n\nAttach the breathing hose and adjust the position so that when the BOV is mounted on the\nrebreather, the mouthpiece will point towards the mouth. When used on Liberty, this position is\nperpendicular to the T-piece.\n\nInstall and fasten the tightening rings with screws. Take special care to ensure that the end\nof the hose is still evenly strapped over the neck of the connector and that there aren’t any\nwrinkles on the hose. This would result in leakage into the breathing hose.\n\nConnect the medium pressure hose to the 2nd stage of the regulator.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#10","type":"component","lock":false,"position":11},{"name":"Image","data":{"firstImage":{"mimetype":"image/jpeg","size":44468,"hash":"e8b0fb9905c7d7abbcd8ec7dcb25117013f7fb52","id":"ck8nl07gg4cee077625t5edya","filename":"dive.jpg","category":"divesoft/","type":"image"},"secondImage":{"mimetype":"image/jpeg","size":44468,"hash":"e8b0fb9905c7d7abbcd8ec7dcb25117013f7fb52","id":"ck8nl07gg4cee077625t5edya","filename":"dive.jpg","category":"divesoft/","type":"image"}},"id":"#47","type":"component","lock":false,"position":12},{"name":"Divider","data":{"color":"darkGray"},"id":"#11","type":"component","lock":false,"position":13},{"name":"SectionDivider","data":{"title":"3.

As in the case\nwhere two liberty units are used simultaneously in\nbackmount + sidemount configuration or in the double\nsidemount configuration. Regardless on which of these\ntwo configurations apply, one unit has to be defined as\na primary unit and one as a secondary (bailout) unit.\nLiberty in the bailout standby mode does not add oxygen\nthrough the solenoid valves, thus not changing buoyancy\nof the unit and wasting oxygen. It is presumed that the\ndiver does not breathe from the secondary unit and\nuses the primary unit. During descent diluent is added\nthrough an ADV, which compensates for the increase\nof pressure and decrease of loop volume. The oxygen\nis measured as normal during the whole dive, the data\nfrom all four oxygen sensors are displayed, including the\nvoltage values and the mean of all sensors.\n\nDuring the Bailout standby (CCR) mode the stack time\nis on hold.

If the diver will start using the unit\nwithout switching it to Dive mode, the mode will switch\nautomatically after a decrease of ppO2 by 20 % bellow\nppO2 of diluent at the current depth. This automatic\nmode is only an emergency solution and at some\nsituations (low depth, hypoxic diluent) can cause acute\nhypoxia of the diver before the automatic switch of the\noxygen addition.

A number of systems have multiple\nbackups. The logic of the Liberty Heavy’s control never prohibits the start of a dive even in the\nevent that malfunctions are detected; it only indicates the status if able to do so in light of the\ndamage. When cave diving, the inability to submerge can mean not being able to return from\na dive; therefore, the Liberty Heavy does not impede submersion.\n\nThe user must always decide responsibly whether he/she switches to a backup apparatus or\neven starts a dive with a partially malfunctioning rebreather.\n\nA Liberty Heavy user must accept the fact that diving involves risk. Following everything that\nthe user has learned in the Liberty Heavy’s technical documentation and in training on diving\nwith this rebreather can reduce the risk but cannot eliminate it. Safety when diving is further\nimproved by regular training, methodical education and following good diving practices.

Divers can clamp the Liberty to their own standard backplate, bringing a high\nlevel of comfort, versatility, and a wide range of height adjustment options for any diver’s body\nheight. This gives the diver ample headroom that does not restrict anything. The adjustability\nof the device’s seating on the back brings the possibilities of fine-tuning the perfect trim.\n\nThe Liberty Heavy configuration has a 20 l wing in the base, but any other rebreather wing (with\nholes for hose passages) can be used according to the required volume to your chosen size and\nnumber of cylinders.\n\nThe Liberty Heavy allows you to change the configuration of the on-board cylinders from the\nclassic 2–3 liter to the large 7 liter cylinders in DIR configuration. Up to 4 cyl

2inders can be\nmounted in various combinations.\n\nThe removable wire stand allows very practical and convenient mounting of the off-board\nbottles while guaranteeing high stability of the device on land or on the boat.\n\nThe stainless steel frame of the instrument is well adapted for easy and elegant hose routing.\n\nThe Liberty Heavy is thus an excellent choice for all divers looking for a very comfortable,\ncompact and stable unit with a wide range of customization options, for divers looking for\na unit for the most demanding dives with many bailout cylinders, but also for recreational\ndivers at the beginning of their rebreather career.\n\nAll the extremely advanced features of the CCR Liberty remain.

Individual internal parts are separated in order to minimize the impact that failure\nof a given part may have on the rebreather’s basic functionality. A number of systems have\nmultiple backups. The logic of the Liberty Sidemount’s control never prohibits the start of\na dive even in the event that malfunctions are detected; it only indicates the status if able to do\nso in light of the damage. When cave diving, the inability to submerge can mean not being able\nto return from a dive; therefore, the Liberty Sidemount does not impede submersion.\n\nThe user must always decide responsibly whether he/she switches to a backup apparatus or\neven starts a dive with a partially malfunctioning rebreather.\n\nA Liberty Sidemount user must accept the fact that diving involves risk. Following everything\nthat the user has learned in the Liberty Sidemount’s technical documentation and in training\non diving with this rebreather can reduce the risk but cannot eliminate it. Safety when diving is\nfurther improved by regular training, methodical education and following good diving practices.\nDiving with a rebreather requires a far higher degree of carefulness and discipline than diving\nwith an open-circuit apparatus.\n\nIf you do not accept the risk and you are not a trained, careful and disciplined diver, do not dive\nwith the Liberty Sidemount.\n\nThe manufacturer does not bear any responsibility for use of the Liberty Sidemount if the\napparatus has been modified in any way that is not stated in this manual or in the technical\nguidelines issued by the manufacturer.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#14","type":"component","lock":false,"position":6},{"name":"TextBlock","data":{"text":"The principle of a rebreather involves in recycling the breathing mixture.

Some of them try to get divers involved in rebreathers as quickly as possible, while others require more experience of the candidate. Often insisting on a level where the diver can dive with a stage bottle, both have their advantages and disadvantages. The advantage of applying for CCR training early on is to avoid any bad habits you can get from open circuit diving. However, on the other hand, this is also a big disadvantage.","content":"In my opinion, a diver **needs to get a certain amount of experience with open circuit because it is the way to go in the event of a catastrophic instrument failure**. A CCR diver may dive closed circuit all the time, but in the event of an emergency a diver will revert to open circuit. That means he has to be sure of its use. If some training agencies allow divers to start diving with the CCR too early, this can lead to tragic ends. \n\n**The most extreme** I have seen is with a training agency that allows you to start with CCR directly as an Open Water Diver, or **after completing only 18 dives**. In my opinion and experience, this threshold is too low. A [diver needs to have an understanding](https://www.divesoft.com/en/blog/7-steps-to-becoming-a-rebreather-diver) of what is going on in the aquatic environment, how to react properly to basic situations such as increasing and decreasing ambient pressure, how to properly handle buoyancy, or how to generally come to terms with being in an environment that we can't ever breathe out of. \n\nFor those of us who have spent a large part of our lives diving these things may already be obvious, but let's put ourselves in the shoes of someone who's just starting. **Let's remember our very beginnings**. I, for example, still remember the feeling when I took my first breath underwater. It was so unnatural. All I had to do at that point was to breathe regularly, equalize the pressure in my ears, and not hold my breath as I ascended. I didn't have to deal with anything else. \n\nTo think that I would have had to know a lot of things about oxygen partial pressure, watch for it, make sure I didn't flood the loop, and be able to immediately switch to bailout from a cylinder strapped to my side, would have been overkill. These are mostly focusing on [the most basic elements of CCR diving](https://www.divesoft.com/en/blog/what-is-a-rebreather-do-i-need-one-as-a-recreational-diver). \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/790cda93b914cd3f56258007dd2940ef401bdd1e_my-project-4.jpg)\n\nFortunately for everyone, standing between the ambitions of the training agencies and the new student is [an instructor](https://www.divesoft.com/en/blog/how-to-choose-an-instructor-for-your-rebreather-course) who can correct the student and personally recommend a moment of patience before starting rebreather training. I'd say all the sensible instructors I know do this too.\n\nThe other thing that determines when a diver can start learning closed circuit is the manufacturer of that particular rebreather. Incorporating the teaching of a particular brand of device into a training system is preceded by a relatively long process of mutual approval between the manufacturer and the training agency. \n\nThe training agency examines whether [the rebreather](https://www.divesoft.com/en/products/ccr-liberty/philosophy) is sufficiently safe and may place conditions on certain elements, such as mandatory BOV, or require certificates of compliance with standards and testing such as CE or UKCA certification. **The manufacturer may in turn define the entry requirements and conditions under which diving with their equipment will be taught.** The manufacturer has the option to standardise training requirements for all training agencies.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/677b4afb9ddab7bbf26afb8469bcad3cf5d23b87_my-project-3.jpg)\n\nIn the case of Liberty, we have done our best to ensure the safety of diving also from the training agencies' approach. **We have created training documents for instructors, which the training agencies have adopted**. At the same time, we set minimum entry requirements for all. These requirements are a minimum of 50 dives, advanced knowledge of nitrox diving including accelerated decompression and the ability to carry a stage or bailout cylinder.\n\nAfter 50 dives, one has at least a reasonable understanding of what is going on underwater and **can concentrate on the other individual tasks set before them**. To start learning to use a stage or bailout cylinder only during rebreather training would be to unnecessarily burden the student with tasks. \n\nThe Liberty is a sophisticated piece of equipment that will offer the user an incredibly wide range of options from the start, and there is virtually n

2othing to prevent even an inexperienced diver from making a dive to 100 m (330 ft) once they have completed their first training with the CCR. However, such a dive may be the last for them, as it is too big a leap. Therefore, **we also require a certain moral maturity**, which cannot be acquired except by knowing all the risks involved in such an activity. This we try to achieve by a higher level of training with which the candidate can undergo training.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/580010ef0ba3999ac601a85a414a8f44843bf093_my-project-2.jpg)\n\nNo matter how low the limit of training agencies, they are bound by an agreement with the manufacturer who has set minimum requirements and can thus offer courses from a certain level and experience of the diver.\n\nDespite all efforts to educate all divers, and to try to improve training procedures and materials, **accidents still occur on all types and brands of rebreathers due to unsafe or irresponsible diver behavior**. In this regard, there is a need to appeal to instructors and perhaps to the training agencies themselves to help weed out divers with unsafe attitudes to diving. \n\nEvery instructor has certainly encountered a student who had exaggerated ambitions or a tendency to underestimate the risks associated with diving or the use of the technique. In such a case,** the instructor should terminate the student's training without certifying the studen**t. But this rarely happens, because instructors rarely have the backing of the training system's standards. \n\nDemonstrating an inability to perform prescribed exercises to a satisfactory standard is very easy, but **demonstrating something as elusive as an unsafe attitude or opinion is very difficult**. Often it is something that just hangs in the air and is very difficult to express. A very experienced instructor has the ability to detect this, but the standards of his training organization usually won't allow him to. This should be changed and implemented into the standards of all training agencies. However, even so, the situation for instructors under commercial pressure will always be difficult.\n\n- Jakub Å imánek","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":986669,"hash":"94c748c937944f6631edcf0990c65a97be4ae9ea","id":"clcg5d6srhhs10776fgn7qokn","filename":"my-project-1.png","category":"divesoft/","type":"image"}},"id":"#4","type":"component","lock":false,"position":1},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":5}],"id":"root","idBuffer":"#6","lastCommit":"562657a9-7314-44d6-b177-3ec78b006c6f"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:clagmvmlz1ek70835369m5n6c.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:clagmvmlz1ek70835369m5n6c.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:clagmvmlz1ek70835369m5n6c.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:clagmvmlz1ek70835369m5n6c.annotations.0":{"key":"title","value":"CCR training from the perspective of training agencies","__typename":"PageAnnotation"},"PageTranslation:clagmvmlz1ek70835369m5n6c.annotations.1":{"key":"image","value":"null","__typename":"PageAnnotation"},"PageTranslation:clagmvmlz1ek70835369m5n6c.annotations.2":{"key":"perex","value":"Training organizations often have different approaches to teaching rebreathers.

Lots of diving with amazing people with no shortage of good stories and incredible memories to keep.","content":"One dive, however, comes to mind due to a number of factors and it is the wreck of USS Perry in Palau.\n\n ![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/edbaa0806e1e36a3cf01f7d9fe42a53c670a2fe4_uss-perry.jpg)\n \n**The USS Perry** (DD-340/DMS-17) was a Clemson-class destroyer in the United States Navy during WWII and the ship was involved in various operations including escorting USS Arizona into Pearl Harbour before the infamous attack. She claimed a number of shot-down Japanese aircraft during the attack. After the Pearl Harbour attack, she served in the Pacific operating mainly as a mine sweeper** ending her career when she struck a mine in 1944 near Angaur Island - Palau**.\n\n ![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/fae6ac8956ea09959f00c387de084d7e9940979a_maps.jpg)\n \n<

2h2>The USS Perry Wreck</h2>\n\nThe wreck was discovered in 2000 and lies on the southeastern tip of Angaur Island in 78m of water and was featured in [one episode of the Deep Sea Detectives TV show](https://www.imdb.com/title/tt0916147/). To our knowledge, **the wreck was dived by less than 30 people at the time** which made it even more special. \n\nThis area is known for its harsh sea conditions, particularly very strong currents which make the potential to dive it quite limited. The last story we heard was that **the divers were picked up 15km away from the wreck site after finishing their drift deco**. \n\n ![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/9b608592b57d535f9733df5208f8a46bc8723ac2_uss-perry-wreck.jpg)\n \n<h2>Unpredictable currents</h2>\n\nAugust 2022 marked 100 years since the ship was commissioned, so it was a good time to attempt to dive the wreck.\n\nThe wreck location is about 1,5 hr by a speedboat from Koror island heading south. When we got to the location **the current was considered too strong to dive even though the local guys said that it was way weaker than what it usually is.** You don't want to get blown off the wreck by the current as the next stop would be Indonesia.\n\nDue to this, there were **strict safety conditions put in place** such as another chase boat with safety divers, a safety plane on standby and a cut-off time for a dive at 2 PM as the plane search is limited at night. Dive permits were also obtained to dive the wreck and our dive plan was carefully planned before the dive.\n\n ![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/cb817e38d38dcf2d86da1c9aca008535d5da9e32_ocean.jpg)\n\nThis was the 3rd and last ONLY date which looked suitable after previous weather forecasts scrapped the plans (most of us were on the plane the next day). We all decided to give it a go. Screw relaxing on the beach.\n\nAs the conditions are **very unpredictable**, there was a decent chance that we will spend a day on the boat staring at the blue water and then returning our full cylinders with TMX back to the dive centre at the end of the day. But we all decided to take the risk.\n\nTesting the strength of the current just in my mask and fins resulted in me zipping by our boat in a manner which didn't feel right to attempt in full gear. Before this, we ended up finding the shot line that was used a week earlier to try to shoot the wreck with 100m of line and totally crushed float buoys. \n\n<h2>Our dive</h2>\n\nApparently, after shooting the wreck the line dragged the buoy below the water, and it all disappeared. **Definitely a current not worth messing with**. We decided to wait it out. After about an hour of the current not slacking off, I decided to take a nap inspired by Antti until I got woken up by:  <i>\"Wake up!!! Wake up, get your breather on Jakub, we are going!!!\"</i>\n\nOur team got ready and started the long pull on the shot, down to the bottom. At about 50m you could start to see the bottom in stellar visibility but no wreck, thinking *„Yeah, they missed it\"*.\n\nWhen on the bottom in the distance we could see something that appeared like a wall. **We headed towards it and the USS Perry started shaping up**. The following time was just a blast of exploring with our dive team. The ship broke where she struck the mine and now lies in an \"L\" shape. When she sank, she dragged another mine down with her which now lies half-buried in the sand near the wreck. The wreck is nicely preserved and extremely interesting to explore. After 25 min of our bottom time, we followed our plan and after taking a stylish selfie began our ascend.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/aa9e7e1277056fcaf266f4f7454b1b7697a35ebe_selfie.jpg)\n \nThis dive was a highlight of the 2-week diving trip with great friends on a very unique site in lucky conditions and ended up being **one definitely of the most memorable dives I have ever done**. Could not ask for more apart from having more dives like this.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/afeffe08cdb73ae1e55079d712bdb0ac623291f1_friends.jpg)\n\n- Jakub Slama\n\n","showTags":false,"showDate":false,"image":{"mimetype":"image/jpeg","size":212531,"hash":"505e3ce1f28e7fdd987c632c0d6cf817ed99189b","id":"clcagzn5kg2j00776ctm92qwz","filename":"uss-perry-main.jpg","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"PhotoGallery","data":{"title":"Photogallery","description":"Check the dive profile and Jakub's underwater photos of the USS Perry wreck","divider":false,"images":[{"id":"

But what is the main difference in scientific diving from the general recreational world? ","content":"Actual **scientific diving** as an occupation **varies both in needs and training with the defined goal of diving to gather data, be that samples, observations or experimental manipulation** carried out by professional scientists or research teams. **Citizen science projects** on the other hand are volunteers from the general community that wish to contribute their skills and expertise, in this case in diving, to assist in data gathering under a structured project where extra assistance is required. Both are important, though different, with the latter adding valuable contributions to researchers understanding of the underwater world.\n\n<h2>Benefits of the use of CCRs for underwater research</h2>\n\nThe next question is **how can the use of CCRs benefit underwater research and why**? The obvious first thought is to get deeper for work with reduced gas costs and reduced risk accosted with deeper range open circuit, but that is just one component. The overall benef

2its from the fundamental nature CCR can develop huge advantages in shallow research in all fields. \n\nThe extension of gas use means **long periods gathering data** can be spent on a dive where classic open circuit gas supplies, rather than decompression, would be limiting factor. **Remote areas where only a smaller compressor** is present but oxygen can be sourced the filling times on the surface can also be addressed in this manner. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/beaa11736789e715fc46e9321236a50df7132a05_scientific-2.png)\n\nA big advantage of CCR is **the extension of depth ranges and bottom times for the ranges 30- 40m**, where current recommendations on gas density suggest helium usage and decompression windows require even larger columns of gas. The fixed setpoint of a CCR means these ranges can be accessed using minimal gasses but also allow multiple levels to be completed moving shallower to gather further data while off gassing there, for example carrying out benthic biodiversity transects or fish surveys (Andradi-Brown et al, 2016). \n\nOne **great advantage in marine biological work is the reduced impact** that a silent diver on CCR has to the surrounding life and potential study subjects behaviour, shown by work on fish surveys comparing CCR and open circuit ( Linfield et al, 2014). \n\n<h2>And the disadvantages</h2>\n\nNow the advantages have been briefly covered, **what about the disadvantages**? The main one is **time and experience diving it requires to be able to dive a CCR** well enough to manage extra task loading that all scientific diving will add. This factor alone already limits the option for many professional scientists that do not have the place in their workload to train or regularly dive on a CCR. \n\nThe idea that 'training a scientist to dive is easier than training a diver to do science' differs when moving across to [rebreathers](https://www.divesoft.com/en/products/ccr-liberty/philosophy) and the skills of experienced teams can be harnessed to collect the relevant data if they have an understanding of the scientific questions being asked under the direction of the actual researcher. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/623f0b198a1c29f6c6452df40e1829bd9a4a94bb_scientific-1.png)\n\nChallenges still exist in this approach as well due to **many countries having defined regulations** on how diving operations in research are carried out with extra considerations to safety and risk mitigation that are not common within the sport diving community.  This applies closed circuit rebreathers in the application as well and in fact some countries that have stricter regulatory standards even do not allow CCRs to be used in occupational application, much to the determent of science in those areas.\n\n<h2>Training for CCR Scientific Diving</h2>\n\nDevelopment in [training](https://www.divesoft.com/en/events-blog/ccr-training-from-the-perspective-of-training-agencies) and technology though is occurring to address the regulatory challenges and educate CCR divers in approaches that allow them to carry out occupational diving activities. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5e86ef7d29939347cb89943f1dbd3b5495c9aedb_scientific-3.png)\n\n**Such examples are in the USA**, with the [American Academy of Underwater Science](https://www.aaus.org/), with their standards allowing for CCR use with correct procedures. **On the European side** there is the [Finnish Scientific Diving Academy](https://www.helsinki.fi/en/research-stations/tvarminne-zoological-station/finnish-scientific-diving-academy), based at the University of Helsinki, which is running European Scientific Diver level programs but aimed at training operation specifically for CCR scientific work, predominately in colder waters with the risk and safety management, procedural development, task loading and other components that are part of occupational scientific diving. \n\nThese are not the only organisations offering training or opportunities and this area will grow as the benefits of CCR application in research grow. \n\n- Edd Stockdale - [Gradient Technical Diving](https://gradient-technical.com/) \n\n**Follow Edd** on [Facebook](https://www.facebook.com/edd.stockdale) and [Instagram](https://www.instagram.com/TecEddAdventures/) to learn more!\n\n[Finnish Scientific Diving Academy](https://www.helsinki.fi/en/research-stations/tvarminne-zoological-station/finnish-scientific-diving-academy)\n- [Facebook](https://www.facebook.com/FinnishScientificDivingAcademy/)\n- [Twitter](https://twitter.com/Fin_Sci_Diving)\n- [Instagram](https://www.instagram.com/finscidive/)\n- [LinkedIn](https://www.linkedin.com/company/finnish-scientific-diving-academy/)\n\n\n**Articles related:**\n- https://gue.com/blog/finlands-newly-established-scientific-diving-academy/\n- https://gue.com/blog/the-swan-a-17th-century-story-at-the-bottom-of-the-baltic-sea/\n- https://owusseurope.org/scientific-diving-in-tvarminne-finland/\n\n\n\nReferences:\n\nAndradi-Brown, D., East, A., Shepherd, LM., Stockdale, EJ., Rogers, AD., 2016 Challenges and opportunities in conducting mesophotic reef research.

Adherence to everything that the\nuser has learned in the Divesoft Freedom’s technical documentation and in training can reduce the risk but\ncannot eliminate it. Safety when diving is further enhanced by regular training, methodical education and\nadherence to good diving practices. Technical diving requires a far higher degree of care and discipline than\nrecreational diving.  \nIf you do not accept the risk and you are not a trained, careful and disciplined diver, do not dive with the\nDivesoft Freedom.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#3","type":"component","lock":false,"position":8},{"name":"Divider","data":{"color":"darkGray"},"id":"#15","type":"component","lock":false,"position":9},{"name":"SectionDivider","data":{"title":"Upgradable computer","skipToC":false},"id":"#454","type":"component","lock":false,"position":10},{"name":"TextBlock","data":{"text":"### <span id=\"upgradable-computer\">**Upgradable computer**</span>  \n\nThe following table is valid only for the original version of Freedom.

Lower values are more suitable for deeper dives including extended range air dives and use of\nhelium rich mixtures. 0 is not uncommon. Use lower value if any risk factor is present. Higher value can\nbe used for relatively shallow dives, but influence of GF Low on these dives is small (zero on so called\nnon-decompression dives).\nDefault GF high 0.80 increases the time at the shallow stops relatively slightly compared to the bare\nBühlmann’s decompression algorithm ZHL. If any risk factor is present, lower value is more appropriate. This\nalso applies if another dive is planned in a short time or physical activity cannot be avoided shortly after\nthe dive. Low value of GF high also shortens so called no-deco limits. GF high 0.50 can be considered as very\nconservative. For an even smaller value is not usually the reason.\n\n**Risk factors**  \nUse a more conservative setting and make only dives with short or no decompression if any risk factor is\npresent.  \nThe major risk factors for decompression sickness (DCS) are:  \n• Dehydration  \n• Heart disease, especially PFO (patent foramen ovale) or ASD (atrial septal defect)  \n• Previous DCS  \n• Older age  \n• Overweight or obesity  \n• Exercise during a dive or post dive  \n• Fatigue  \n• Irresponsibility or inability to follow proper decompression procedures  \n\nIf excessive fatigue or any other subclinical form of DCS occurs after a dive during which a proper\ndecompression was performed then the presence of one or more risk factors can be assumed.\n\n**Diving with air or one nitrox mixture**  \nConfirm the following settings:  \n• The default OC mix is set to air or nitrox, whichever one you plan to use (Setup → Mixtures)   \n• All other gas mixtures are disabled (no checkbox checked on the list Setup → Mixtures → Mixture\nsetup)\n\n<span style=\"color:red\">

2**Warning: if the ascent gas is set to Optimal (Setup → Decompression) and multiple gas mixtures are\nenabled then the decompression plan expects their use.** </span>\n\nThis may lead to indication of shorter time to\nsurface (TTS) and shorter decompression stops. Improper settings like this can’t affect the safety of the\ndecompression if you strictly follow the computer; it only affects the calculation of the plan. This is not\napplicable to the Basic nitrox version of the Freedom.\n\n**Multi-day repetitive dives**  \nIt is advised to use a slightly more conservative setting for diving holidays. Do not disable or omit the safety\nstop. Use nitrox if available and if you are qualified.\nRemember that the diving computer does not know diver’s physical shape. Maintain a high level of hydration\nduring diving holidays. Do not dive drunken or hungover. Do not dive ill.\n\n**Long decompression safety**  \nPreferably, control the decompression safety with the GF high setting and disable the safety stop if the\ndecompression obligation is longer than 20 minutes. A smaller value of the GF high setting can be used\nadditionally for increasing safety on the shallow end of decompression, if required.\nSwitch to bailout gradient factors if you wish to reduce the decompression time (while increasing the risk\nof DCS). Bailout GF’s shall be properly set before dive.\n\n**Multiple gas usage**  \nThis is not applicable to the Basic nitrox version of the Freedom.\nMultiple gas usage requires appropriate qualification from a recognized training agency.  \n\nConfirm the following settings:  \n• The ascent gas is set to Optimal (Setup → Decompression)  \n• All gas mixtures, which you plan to use are properly set and active; and other gas mixtures are\ninactive (Setup → Mixtures → Mixture setup)  \n• The default OC mix is set to the gas you plan to descend with  (Setup → Mixtures)  \n• The gas switch time is set to your preferred time (commonly 2 or 3 minutes)  \n\nNever switch the computer to another gas before you start breathing it. Make sure that you breathe the\nright gas with the MOD greater than your current depth.\n\n**\nExtreme deep diving**  \nEvery technical diver who dives to depths greater than 100 m/330 ft has to develop his or her own\ndecompression strategy. It is necessary to increase the personal limit gradually, step by step. The maximum\noperating depth of the Freedom is 300 m/1000 ft. This is probably a much greater depth than you and your\nbody could handle.\n\nFor extreme depth, short bottom-time decompression strategies are common:  \n• Dive only if in really good physical shape; get your heart examined for PFO  \n• Use the computer only as a backup for the plan based on your previous experience  \n• Use a very low value of the GF low; 0 is not uncommon  \n• Use a high value of the GF high; 1 is not uncommon and even >1 is not uncommon (requires the\nspecial, personally granted license)  \n• Use optimal gas mixtures  \n• Stay in the water for minimum 15 minutes after surfacing  \n• Avoid post-dive exercise; take advantage of the support team  \n• Maintain thermal comfort during a dive; avoid a hot shower after the dive  \n• Avoid diving or any other pressure change in the following 48 h  \n\nThe Divesoft Freedom is not intended for long bottom-time extreme deep diving in any mode other than the\ngauge mode.  \n\nThe Full trimix or the CCR version of the Divesoft Freedom is required for trimix decompression calculation.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#230","type":"component","lock":false,"position":237},{"name":"Divider","data":{"color":"darkGray"},"id":"#231","type":"component","lock":false,"position":238},{"name":"SectionDivider","data":{"title":"4.

These units were designed by cavers and first tested by cavers. The durability of the Liberty was a key element straight from the beginning and was always kept in mind during the tests. ","content":"Confined spaces, typically caves or wrecks, can be an excellent training ground for resilience. In these environments, contact with solid \"obstacles\" such as the ceiling of a cave or the structure of a wreck is often unavoidable. During transport, contact with the cave or other surfaces cannot be avoided, especially if divers are transporting equipment via crawling caves. \n\nWhen an obstacle is hit, it is the [rebreather](https://www.divesoft.com/en/products/ccr-liberty/philosophy) that must often \"swerve\" or absorb the impact. This often involves sharp or abrasive surfaces, e.g. corroded wreck structure, sharp protrusions in caves due to the genesis of the cave or fillings (speleothems - decorations). \n\n**The resistance of the unit can be categorized 

2into three areas:** \n* The inherent resilience of the unit,  \n* transport resistance, and  \n* resistance to diving, especially in confined spaces.  \n\nThe intrinsic resistance of the unit is determined by the quality of workmanship, the materials used and its philosophy a Fault Tolerant Rebreather, which Divesoft promotes. The quality of the unit's workmanship can also be seen in person at many events worldwide. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5f6b909aa628ce8e54dcbcbcd0b3a080746328e9_resistant-2.png)\nEntrance to JuriÅ¡ko Vrelo, photo by Přemek\n\n<h2>Installation of the unit in a confined space</h2>\n\nCave diving in most karst areas cannot do without transporting gear through caves, often through crawling caves or single-rope technique through verticals. **The unit is often transported by the diver in a semi-disassembled state**. With full weight, it is impossible to complete the heavier rope sections or push it through the crawlway; the whole back unit cannot be put into the speleothem.  \n\nSubsequent assembly takes place in a confined space with an unlimited amount of sediment, which **fundamentally limits the delicate handling of technically advanced equipment**. Liberty rebreathers have also been tested in this environment with compelling success. Examples include crawl transport in Chýnov Cave, rappelling down the rock in Alberic Cave, siphon diving (sump diving) behind the Grande Siphon in the North Branch of Bue Marina, etc.  \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/b4216cef692ed578d46b2ce9868aeae55caa4184_resistant-3.png)\nChýnovská cave, photo by M. Dvořáček\n\n<h2>Scratches are inevitable</h2>\n\nThe Liberty will have no respite even after plunging, especially in the flooded crawlspaces. **Contact of  the sidemount unit with rock is inevitable**, the unit's body grinds against the rock and the lungs are clawed by sharp protrusions. More than once, a diver is left hanging by the hand set cable, typically in zero visibility while trying to free another jammed piece of gear, etc.  \n\nWith the Classic Backmount unit, the head and buddy light suffer the most. Low caves stirred up halocline or otherwise reduced visibility while swimming... and contact with the ceiling can be difficult to avoid. If a diver hits the ceiling while scooting and it shows up as a small scratch on the buddy light, what more could you ask for? With the cave head cover, all worries are completely put to rest. Proof can be seen in the dives in JuriÅ¡ko Vrielo, the tunnels around JíloviÅ¡tě, the caves in Sardinia, etc. \n\nWe also proved the unit's resilience during last year's expedition to JuriÅ¡ka Vrelo, we left the unit between dives in the cave near the spring, where the relative humidity is almost 100%. **The unit was then in the cave for 4 days, completed 3 dives and worked with all sensors without any problems all the time**. Not a single oxygen sensor was disabled. \n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/3b3dc512ac2facf295e32396e226a47b284c0ac6_resistant-4.png)\nMine adit, author selfie\n\n- [Petr Chmel](https://speleoaquanaut.cz/clanek-spolupracujeme-s-pustym-zlebem-expedice-meduza-2022-1-489)","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":1434033,"hash":"6dbfaae32587b37b0bb4a2a0a49747b157b310e2","id":"clg24s0mynmq707765tsovg37","filename":"main-resistant.png","category":"divesoft/","type":"image"}},"id":"#3","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#5","type":"component","lock":false,"position":2},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":5}],"id":"root","idBuffer":"#6","lastCommit":"41cb737c-512a-465b-b5d7-225bb885b4a2"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:clg24qsz9oqiy083513ouzbmz.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:clg24qsz9oqiy083513ouzbmz.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:clg24qsz9oqiy083513ouzbmz.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:clg24qsz9oqiy083513ouzbmz.annotations.0":{"key":"title","value":"CCR Liberty cave diving resistance","__typename":"PageAnnotation"},"PageTranslation:clg24qsz9oqiy083513ouzbmz.annotations.1":{"key":"perex","value":"CCR Liberty rebreathers have cave diving DNA.

Underwater archaeologists are thrilled by the hidden secrets in this area, which have revealed valuable information about **long-distance trade routes between the Black Sea, Aegean Sea, Cyprus, the Levant, and Egypt** throughout the ages.\n \n ![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/40852c5405bf183da24e266f64e41f88186712f5_fournoi-00004.jpg)\n \n<h2>Astonishing Diversity of Cargoes and Shipwrecks</h2>\n\nThe experts were not only surprised by the number of shipwrecks spanning various centuries but also by the diverse cargoes they carried, some of which were found for the first time. The multitude of wrecks is likely evidence of the significant traffic in the area rather than the area being unsafe.\n\nOut of the 58 shipwrecks identified in the Fourni archipelago, one in particular stands out the most due to its structural integrity and diverse cargo. This shipwreck carries **six different types of amphorae, originating from the Crimea and Heraclea Pontica regions**, along with domestic pottery from the Phocaea region in northwestern Asia Minor.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/862fae10f996a52e474dd49c4559419c72ce620d_fournoi-00001.webp)\n\n<h2>Uncovering Hidden Treasures and Precise Dating</h2>\n\nDuring the 2021 and 2022 surveys, researchers cleared sand deposits and opened a test trench, revealing the wreck's stratigraphy. Around 15 buried amphorae were uncovered, including one type attributed to the city of Sinope on the Black Sea. \n\nIn addition, table wares and wooden parts believed to be from the vessel's hull were retrieved. These findings allowed scientists to **date the wreck quite accurately between 480 and 520 AD**, likely during Emperor Anastasius I Dicorus' reign (491-518 AD), who is known for his fiscal and monetary reforms that fueled the expansionist policies of 6th-century emperors.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/51c4396fc54d77e17f63a8b97f6f2d42a6d8fb51_fournoi-00013.jpg)\n\nThe Fourni archipelago's astounding shipwrecks offer a unique window into the past. These artifacts continue to provide invaluable insights into ancient maritime trade and the history of the Mediterranean region.

Set brightness to a high level (6 to 9) and a short screensaver timeout\n(15 s is more than enough).\nPreferably activate the display by light during a dive. Move the Freedom to the light beam instead of moving\nthe beam to prevent confusion with a light signal.\n\n**Low brightness**  \nFor diving with eyes accommodated to darkness use the lowest brightness setting (level 1). Your night\nvision will not be disturbed. It is preferred to have the display on all the time (i.e. screensaver timeout set\nto 0). This option is typical for night dives in clear water.\nDive with slightly brighter display while using a low power torch. Balance the power of the backlight to the\npower of your torch to find the optimal setting – no glare but good readability.\nThe display can’t shine through disturbed silt or mud on low brightness.

Lower values are more suitable for deeper dives including extended range air dives and use of\nhelium rich mixtures. 0 is not uncommon. Use lower value if any risk factor is present. Higher value can\nbe used for relatively shallow dives, but influence of GF Low on these dives is small (zero on so called\nnon-decompression dives).\nDefault GF high 0.80 increases the time at the shallow stops relatively slightly compared to the bare\nBühlmann’s decompression algorithm ZHL. If any risk factor is present, lower value is more appropriate. This\nalso applies if another dive is planned in a short time or physical activity cannot be avoided shortly after\nthe dive. Low value of GF high also shortens so called no-deco limits. GF high 0.50 can be considered as very\nconservative. For an even smaller value is not usually the reason.\n\n**Risk factors**  \nUse a more conservative setting and make only dives with short or no decompression if any risk factor is\npresent.  \nThe major risk factors for decompression sickness (DCS) are:  \n• Dehydration  \n• Heart disease, especially PFO (patent foramen ovale) or ASD (atrial septal defect)  \n• Previous DCS  \n• Older age  \n• Overweight or obesity  \n• Exercise during a dive or post dive  \n• Fatigue  \n• Irresponsibility or inability to follow proper decompression procedures  \n\nIf excessive fatigue or any other subclinical form of DCS occurs after a dive during which a proper\ndecompression was performed then the presence of one or more risk factors can be assumed.\n\n**Diving with air or one nitrox mixture**  \nConfirm the following settings:  \n• The default OC mix is set to air or nitrox, whichever one you plan to use (Setup → Mixtures)   \n• All other gas mixtures are disabled (no checkbox checked on the list Setup → Mixtures → Mixture\nsetup)\n\n<span style=\"color:red\">**Warning: if the ascent gas is set to Optimal (Setup → Decompression) and multiple gas mixtures are\nenabled then the decompression plan expects their use.** </span>\n\nThis may lead to indication of shorter time to\nsurface (TTS) and shorter decompression stops. Improper settings like this can’t affect the safety of the\ndecompression if you strictly follow the computer; it only affects the calculation of the plan. This is not\napplicable to the Basic nitrox version of the Freedom.\n\n**Multi-day repetitive dives**  \nIt is advised to use a slightly more conservative setting for diving holidays. Do not disable or omit the safety\nstop. Use nitrox if available and if you are qualified.\nRemember that the diving computer does not know diver’s physical shape. Maintain a high level of hydration\nduring diving holidays. Do not dive drunken or hungover. Do not dive ill.\n\n**Long decompression safety**  \nPreferably, control the decompression safety with the GF high setting and disable the safety stop if the\ndecompression obligation is longer than 20 minutes. A smaller value of the GF high setting can be used\nadditionally for increasing safety on the shallow end of decompression, if required.\nSwitch to bailout gradient factors if you wish to reduce the decompression time (while increasing the risk\nof DCS). Bailout GF’s shall be properly set before dive.\n\n**Multiple gas usage**  \nThis is not applicable to the Basic nitrox version of the Freedom.\nMultiple gas usage requires appropriate qualification from a recognized training agency.  \n\nConfirm the following settings:  \n• The ascent gas is set to Optimal 

2(Setup → Decompression)  \n• All gas mixtures, which you plan to use are properly set and active; and other gas mixtures are\ninactive (Setup → Mixtures → Mixture setup)  \n• The default OC mix is set to the gas you plan to descend with  (Setup → Mixtures)  \n• The gas switch time is set to your preferred time (commonly 2 or 3 minutes)  \n\nNever switch the computer to another gas before you start breathing it. Make sure that you breathe the\nright gas with the MOD greater than your current depth.\n\n**\nExtreme deep diving**  \nEvery technical diver who dives to depths greater than 100 m/330 ft has to develop his or her own\ndecompression strategy. It is necessary to increase the personal limit gradually, step by step. The maximum\noperating depth of the Freedom is 300 m/1000 ft. This is probably a much greater depth than you and your\nbody could handle.\n\nFor extreme depth, short bottom-time decompression strategies are common:  \n• Dive only if in really good physical shape; get your heart examined for PFO  \n• Use the computer only as a backup for the plan based on your previous experience  \n• Use a very low value of the GF low; 0 is not uncommon  \n• Use a high value of the GF high; 1 is not uncommon and even >1 is not uncommon (requires the\nspecial, personally granted license)  \n• Use optimal gas mixtures  \n• Stay in the water for minimum 15 minutes after surfacing  \n• Avoid post-dive exercise; take advantage of the support team  \n• Maintain thermal comfort during a dive; avoid a hot shower after the dive  \n• Avoid diving or any other pressure change in the following 48 h  \n\nThe Divesoft Freedom is not intended for long bottom-time extreme deep diving in any mode other than the\ngauge mode.  \n\nThe Full trimix or the CCR version of the Divesoft Freedom is required for trimix decompression calculation.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#230","type":"component","lock":false,"position":191},{"name":"Divider","data":{"color":"darkGray"},"id":"#314","type":"component","lock":false,"position":319},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":344},{"name":"Spacer","data":{"spacingLarge":30,"spacingSmall":20,"backgroundColor":"#ffffff"},"id":"#410","type":"component","lock":false,"position":345},{"name":"Spacer","data":{"spacingLarge":30,"spacingSmall":20,"backgroundColor":"#ffffff"},"id":"#417","type":"component","lock":false,"position":346}],"id":"root","idBuffer":"#438","lastCommit":"cffb688b-7b3c-465c-a948-66170c75951d"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cljck5m2r930n08357znc2yvi":{"id":"cljck5m2r930n08357znc2yvi","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cljck5m35930u083591jldpxa","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cljck5m35930u083591jldpxa":{"id":"cljck5m35930u083591jldpxa","name":"Freedom user manual 02","createdAt":"2023-06-26T07:49:18.736Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

We've just returned from diving off Elphinstone Reef where we managed some funny photos with longfin sharks. One photo is of a diver from Belgium who was part of our group. \n\nBoth of our nations have a generally positive relationship with beer, so we exchange photos at the bar in the evening. The discussion revealed that we have both been rebreather diving for a long time and are interested in wrecks. But why am I starting my story about diving off Shetland in Scotland in Egypt?","content":"![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/bd1a3f3c70e6524bfa210be0f5c4d03456d064cd_1.jpg)\n<h2>From Norway to Shetland</h2>\n\nRoel and I continue to keep in touch and occasionally like each other's interesting photos and experiences. Once Roel approached me about the possibility of a CCR safari in Norway, organised by Scottish Shetland. After a moment's thought, I nodded and pondered the risks of diving with a buddy I'd never been in the water with, a group of people I didn't know at all, and a boat that was actually a converted fishing barge. Over the next few months, two more spots opened up on the boat and so my fears were greatly diminished by the participation of Tomas Zloch, who I had already dived with and was glad to have joined. And why are we still in Norway?\n \n ![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c423adb52748b4bf9c306b435aff23353d0a1dfc_2.jpg)\n \nWe were impressed by the Norwegian expedition and understood the rules and procedures that apply on a Scottish ship. Apparently **our approach to diving, based on an emphasis on safety and a positive experience, also attracted the attention of the Scottish divers**, who after an initial distance began to communicate with us warmly. Therefore, when the invitation to participate in an expedition aimed at discovering deep wrecks off the Scottish Shatlands came, there was nothing to think about!\n\t\nThe planning of the trip was clear after the experience in Norway - we would be on ferries for most of the route and minimize driving time - especially in England. The plane option was out of the question due to the amount of gear. As the plan was to **dive wrecks at depths of up to 120m, it was clear that the only way to plan and safely execute such dives was to use two CCRs**. In my case, these were the primary unit, the <a href=\"https://www.divesoft.com/en/products/ccr-liberty/ccr-liberty-bmcl-fmcl\"><b>CCR Liberty in the FMCL variant</b></a> and the <a href=\"https://www.divesoft.com/en/products/ccr-liberty/ccr-liberty-sidemount\"><b>

2CCR Liberty in the Sidemount</b></a> variant as the <a href=\"https://www.divesoft.com/en/blog/diving-with-bailout-rebreather\">Bailout unit</a>. Currently, I don't think there is a more ideal solution as Divesoft has developed firmware that supports just the use of two units in Primary - Bailout mode.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/840e8be2caaa1bd1325c98384d23a8c329a5f654_3.jpg)\n\n<h2>The Unpredictable North Sea</h2>\n\nThe diving in the North Sea around Shetland is wonderful, but **highly dependent on the weather**. The combination of ocean waves with tidal current and local wind is particularly problematic. This unfortunately only allowed us to make one of the planned deep dives. The remaining 5 days we dived known wrecks in areas outside the open sea at depths of up to 70m. These WWI era wrecks were no longer in a fully compact state, but contained a large number of beautiful details and artifacts. What was particularly nice was that, unlike Egypt or the Mediterranean, **these artefacts are not salvaged**.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/d624366456e258691eebcc0662a90767b338bd44_4.jpg)\n\nThe uncompromising weather forecast was exactly confirmed and finally the last day of our expedition came with calmer water. Due to our planned departure, we had to wake up very early to make our dive in the morning tidal window when conditions are at their best. The original, ideal dive plan for the expedition was to discover more wrecks. \n\n<h2>The Pinnacle Dive - The German Submarine UC-55</h2>\n\nFor one dive, the site where the **German submarine UC-55** was sunk in 1917 was chosen. **The minelaying submarine was operating in the North Sea and a total of 9 ships fell victim to it**. It suffered a fatal malfunction leading to loss of control and submergence below operational depth. Subsequent water in the engine room caused chlorine leakage from the batteries and the need to surface, where the submarine was already an easy target for Allied ships.\n\nThe information from the Royal Navy archives and the sonar scan of the bottom clearly indicated that **we were descending to UC-55**. But still, I had an adrenaline rush and a curiosity to see what condition the submarine was in **after 106 years of not being seen by the human eye**. The descent down the ro

2pe was not so idyllic and the considerable current that tilted the descent rope extended our descent to 105 meters. The middle part of the descent in particular seemed interminable, the daylight had already completely disappeared and our torches were still not reaching the bottom. We were \"kicking\" against the current. And suddenly we see her !!! Quickly place the strobe light on the rope, turn on the camera and video lights and hurray to discover.\n\n<h2>Identification Challenges Underwater</h2>\n\n**To identify the wreck accurately, we had two plans.** Plan \"A\", based on **finding the serial number of anything**, was rejected from the first moments. The propeller was so overgrown with vegetation that accessing its serial number would have meant some time of cleaning and scraping, followed by sediment floating away. On one dive below 100 metres there really wasn't time for that. Hence plan \"B\" - **to monitor the damage to the submarine and compare it with the description of events and the condition of the submarine just before it sank**, recorded by the Royal Navy directly from the ships that had a hand in the disposal. In the allotted time we just manage to swim around the submarine and stop for a moment at the guns, turret, mines and a few other details.\n\nLast we leave the submarine in the agreed runtime and climb up. During the ascent we disconnect the decompression trap from the descent rope and for the next 2 and a half hours we and three other divers will be carried by the current. The decompression option with the trapeze unattached completely eliminates the influence of the current and the need to hold on to the trapeze. But the effect of the waves does not leave us and therefore the whole decompression we are in a fully neutral buoyancy with minimal chance to be helped by the constantly bouncing trapeze.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/44107ff4e28b9eaf0e2bec7c9efb2dc857a8a6ec_5.jpg)\n\n<h2>The Euphoric Return</h2>\n\nWe are on board and euphoria reigns. We are debating the details of the dive and still on the camera displays showing the captain the details of the submarine. **It's clear, confirmed, it's UC-55**. The submarine is compact with some damage but **well-preserved features**. We agree that for the completeness of our experience, the submarine deserves at least two more dives. The euphoria slowly fades and the next step is to pack up the gear and leave.\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/cf8169b1905058f7f2d3ef2f5c3cc570f9bcaf04_6.jpg)\n\nUpon returning home, a pleasant mood of interest in our discovery begins to prevail. **[The BBC issues a report on its homepage](https://www.bbc.com/news/uk-scotland-north-east-orkney-shetland-66302352)** and a prime time interview with a Scottish colleague follows. Various diving magazines and websites ask permission to publish photos, and requests for interviews and lectures come in. It's very enjoyable and keeps me coming back to UC-55 in my thoughts. \n\t\nI think that **discovering a wreck is a dream of most divers**, it came true for me and I am grateful for it and only in the corner of my soul I dare to dream that it could ever happen again to me, a Central European.\n\n\n![](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/41a3016efa1bd528c3afbf962c083bab43963c5a_7.jpg)\n\n\n<h3>About the author</h3>\n\n<h4>Martin Mako Janeček</h4>\n\n\"I've been diving since 2002, when I first did several \"intro\" dives in different locations around the world such as: Kenya, Dominican Republic, and Egypt. Subsequently, I completed my OWD and AOWD in Egypt, and started diving recreationally on a regular basis. \n\nIn 2010 I combined my diving with [Kapr Divers](https://www.kaprdivers.cz/) where I gradually became a technical, cave, and trimix diver. In 2015 I became the happy owner of a CCR Liberty Rebreather, and underwater adventure took on a new dimension. I became interested in \"drowned\" history and gradually dived the wrecks of Egypt, the Baltic, Florida, South Africa and the Mediterranean. I had the opportunity to be present at the identification of the B-24 bomber in Croatia, and the exploration of the foundations of the Judith Bridge in Prague. \n\nI was enchanted by the history under the surface of both the Slap and Orlíkka reservoirs, where I had the opportunity to be part of the team that filmed a documentary focused on the flooded Těchnice church, which is regularly broadcast on several TV stations. The biggest bonus of diving for me is my wife Lucie, who I met in the Kapr Divers team and we continue to happily go through life together, not only underwater.\"\n\n[https://www.facebook.com/mako.janecek](https://www.facebook.com/mako.janecek)\n\n[https://www.kaprdivers.cz/](https://www.kaprdivers.cz/)\n","showTags":false,"showDate":false,"image":{"mimetype":"image/png","size":566612,"hash":"39666f7d2209aaa1dce14fdd72cc45ede55bc6ae","id":"clmg82ziot6zk07769n2zkrka","filename":"header.png","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

Configurations are a balance between the diving environment and the user’s comfort. Normally, dictated by the underwater environment, rebreathers must take a step further by being an ambient pressure system, operating underwater, be robust, perform well, be comfortable to wear, and must even travel well!","content":"![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/371e4881a016a297b0d3fc803d81b7c01ac11501_divesoft-photo-047.jpg)  \nDivesoft's vision was to reimagine the closed circuit rebreather design and begin again from the ground up. The Liberty Classic configuration was created unconventionally by designing the unit around work of breathing and fault tolerance. The only conventional aspect of the classic was that it is 

2worn on the divers back and employed front mount counterlungs. This initial design has grown and evolved into the line up that we see today of the Liberty Classic, Heavy, and the popular Liberty Sidemount rebreather.\n\nIt’s easy to go beyond the scope of this post by diving into the history of rebreather design and how they were worn and configured. We are going to focus on popular configurations, Chest mounted rebreathers, backmounted (BM) rebreathers, and sidemount (SM) rebreathers.\n\nThe configuration and design of the rebreather is critical because it affects the hydrostatic pressure between the diver and rebreather (Closed Circuit Rebreather or CCR). The hydrostatic balance of the counterlung location, the divers trim, and the unit’s design all affect the overall work of breathing (WOB). WOB is a critical factor because the divers lungs move the gas through the system, if there are any disruptions or imbalances that create more work, this can cause fatigue, CO2 retention, hypercapnia and even asphyxia.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/58b56661af83bfc8d3577c391b816976d77303fe_divesoft-photo-050.jpg)  \nHistorically rebreather design and configurations being mostly shaped by WOB which meant placement and orientation of the counterlung system lead to design focus. Logically the best hydrostatic balance was what was close to the user's chest, this led to the obvious chest mounted rebreathers. Simple and effective units that began life as primarily oxygen systems and later evolved into mixed gas systems are now popular again as they travel extremely well and often have good WOB.\n\nMoving forward in rebreather evolution and even skipping ahead of semi-closed systems (robust and simple designs that were a branch away from fully closed rebreathers to work around pesky electronics) leads us to mixed gas electronic CCRs such as the CCR Liberty Classic. The first backmount configuration started life with front mounted counterlungs. This was the go-to configuration for high performance rebreathers because they utilized the reliable WOB close to the users chest but able to easily add gasses and integrate a simple and effective automatic diluent valve. Many users prefer this configuration as it is a very effective and proven configuration for deep rebreather diving. Other than front mounted counterlungs we also had encased counterlungs housed within the rebreather assembly on the divers back. We continue to see this around with a few manufacturers.\n\nIn the last 12 or so years there has been a revival of rebreathers and what is now available on the market has given the consumer a huge variety in rebreathers and how they are configured. Backmounted counterlungs (CL) that are free and unencumbered by a case have become more popular than frontmounted counterlungs. Gas addition manual add valves have gone from a handheld block to the Divesoft Liberty’s popular mouthpiece manual add valves (MAVs). The phrase, “If you can find your mouth, you can find your MAVs”, has proven this configuration to be very user friendly. Back-mounted counterlungs have a variety of advantages, such as, a clear chest, good work of breathing, lung placement allows for the diver to exhibit good trim, effective breathing in all orientations, dewatering capabilities, and effective protection of water intrusion to the electronics through water traps and “T” pieces.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5d3c503908977662655bd048f84503d058a5d98a_divesoft-photo-079.jpg)  \nSidemount rebreathers have also become another very popular configuration with exploration because they allow us to utilize rebreather technology through restrictions safer than before. A true sidemount rebreather is completely self contained and is worn similar to a single sidemount cylinder. The Liberty sidemount configuration specifically is a complete system with both diluent and oxygen gas on board, easily removable, and has redundant computers, and redundant displays.\n\nSidemount rebreathers are an incredible tool and great way to configure a rebreather for expedition diving because they are able to travel well, can easily offboard gas into the unit, and should be removable in a manner similar to a SM cylinder. Limitations of Sidemount rebreathers are that they are not as flood tolerant as a backmounted rebreather because any water trap or “T” piece would hamper the work of breathing, thus, any water intrusion will migrate directly to the rebreather's electronics and scrubber. Thus, it is critical for a sidemount rebreather to employ a robust water resistant scrubber such as a radial scrubber and resistant electronics. Hydrostatic loading is also very depen

2dent on the unit’s orientation within the water. The diver’s trim has a significant impact on the work of breathing. Combined with the water vulnerability and easy changes in WOB from the divers trim, they often defend the notion that sidemount rebreathers are more advanced and having CCR experience with a BM unit will help the divers experience with SM rebreathers.\n\nA rebreather diver can combine the configurations of a double BM rebreather or combine a BM rebreather with a sidemount rebreather to employ a primary rebreather with a backup rebreather or “bailout” rebreather. This configuration is relatively new to the community and has been defined between a “Dual Rebreather or Dual CCR” or a “Bailout Rebreather”. This different nomenclature defines two different functionalities, one that both rebreathers are being used in conjunction during the dive and the diver is swapping between the two breathing loops in a certain time interval not only for functional verification of the second unit.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/28b004643faf0a6e4053df0aadeba784a5844584_divesoft-photo-018.jpg)  \nTwo, the bailout rebreather is defined as the purely backup rebreather for the diver. This means that the diver is on one primary system and only changes between loops to verify breathing loop integrity during depth changes or over time. Loop integrity and function check are critical to be constantly monitored. Discussion on the management of this goes well beyond the scope of rebreather configurations. A double BM rebreather would employ a set of backmounted CL and frontmounted CL. A primary BM unit and a SM unit would ideally use BM CL to maintain a clear chest for the SM rebreathers loop to remain at the ready for the diver.\n\nWith all of the development in rebreathers in the last 24 years one begs to ask the question. What does the future of rebreather configurations look like? Will it look like dual systems such as Closed Circuit Rebreather combined with an Open Circuit system backup? Or will we move to a trifecta of a Primary Closed Circuit Rebreather, Bailout Closed Circuit Rebreather, and an Open Circuit system? Or will we remove the Open Circuit system completely and just have a primary CCR and bailout CCR?\n\nThe OC scuba system will forever be utilized SCUBA systems because we will always need a diluent and inflation gas systems to drive the rebreathers. It will likely just move from being a complete breathing gas to primarily drive gas system for the rebreathers that the diver may also breathe from through a bailout valve (BOV) during a transition between both systems.\n\nWhichever way the community goes, it will likely be a combination of things as every diver has a different experience and dive sites have different requirements. What will be critical is that we will need manufactures that are willing to innovate and be receptive to the divers requirements in order to continue the sport of underwater exploration. We are truly living in an exciting time as there has never been more resources and support for underwater exploration than there are today.\n\nAuthor: Joseph Jonathan Bosquez","showTags":false,"showDate":false,"image":{"mimetype":"image/jpeg","size":336757,"hash":"7869d0352d1c09534e72c934422b7f95f8a9d055","id":"cluwpfdfuik600776qwi0kefl","filename":"joseph-jonathan-bosquez.jpg","category":"divesoft/","type":"image","alt":"Joseph Jonathan Bosquez"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#4","type":"component","lock":false,"position":2},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":4}],"id":"root","idBuffer":"#5","lastCommit":"75f3bbf0-90ed-4598-9258-555ced8afab1"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:clutqecknfy2n0735f8y5e38q.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:clutqecknfy2n0735f8y5e38q.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:clutqecknfy2n0735f8y5e38q.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:clutqecknfy2n0735f8y5e38q.annotations.0":{"key":"title","value":"Rebreather Configurations","__typename":"PageAnnotation"},"PageTranslation:clutqecknfy2n0735f8y5e38q.annotations.1":{"key":"perex","value":"Rebreather configurations are a critical element of the diving system just like conventional open circuit diving, such as backmount and sidemount.

Why do we carry a complete backup egress system to our rebreather? Why don’t we carry a backup egress system to our OC system? Are all bailouts the same? What makes a bailout system better than another? In this blog post we will discuss what type of factors we consider while planning for when things go FUBAR and we have to get ourselves back to the surface.","content":"![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/0749cabee399ecb9bff06dba4280f3b7b1feb1e0_divesoft-photo-070.jpg)  \nBailing out is a term used by technical divers to refer to a backup system to get the diver back to the surface. When I teach divers how to use rebreathers, I define the rebreather as the primary SCUBA system and the OC SCUBA as the secondary system. It doesn't necessarily have to be a rebreather (CCR) and an open circuit (OC) system, it can be two OC systems or two CCR systems. Then we have to ask ourselves, why just two? Why not three? It’s quite easy to get buried in the weeds, but in the end divers have to balance what is reliable with what is practical.\n\nOpen Circuit bailout is 1.5x the amount of gas you need from maximum penetration to return home. It is not gas for your buddy, unless the dive team plans to utilize a “team bailout” strategy. Whether you carry all of your gas with you in case you get blown off the wreck or stage cylinders nicely in the cave, you have to plan it and carry it yourself.\n\nCCR bailout or a [bailout rebreather](https://www.divesoft.com/en/products/ccr-liberty/bail-out-rebreather) is a second rebreather that is utilized to return home in the event of a failed primary rebreather. This is often utilized in conjunction with some additional OC gas that acts as a transition gas and drives the diluent of both primary and secondary rebreathers. A Bailout rebreather must be able to independently function but does not need to be transferable. Transfer of a bailout rebreather in a team bailout setting is a particular strategy that must be planned for before the dive. The rebreather is also a backup decompression system because the primary focus will be for the diver to get back to the door quickly and begin decompression as soon as possible.\n\nTeam bailout is often scrutinized and is associated with divers individually not carrying enough OC gas but are required to depend on a buddy to get home but that does not necessarily have to be the strategy. When a cave undergoes a period of lots of diving, such as the exploration of P3, or Weeki Wachee, divers will stage safety cylinders that are placed throughout a system to supplement the diver in the event of an equipment failure and make sure the diver has enough gas to safely get to the surface. Team mates do not depend on this gas but it does create a nice and cozy margin for project divers. Habitats with staged decompression gas are a critical piece of the bailout strategy along with Habitat rebreathers and redundant power sources.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/0f8afd80cd69ce9cccf3ea600547d0b5b7ca8d5c_divesoft-photo-005.jpg)  \nAt NASA, during EVA operations there are three types of egress scenarios; 1st being standard, we have reached the end of our objectives and to adhere to the timeline, time to pack up the worksite and make our way back to the door. 2nd, there is a pressing problem and we need to organize ourselves efficie

2ntly, pack up the worksite, end the mission and begin to make our way back to the door. 3rd, the emergency scenario where we leave the worksite immediately and all priorities are to egress to the airlock. \n\nIn rebreather diving, the parallel is the 1st scenario of staying on rebreather the entire dive, the ideal dive. 2nd, would be the rebreather has encountered a failure and PO2 monitoring/control has failed or the scrubber is no longer usable. Going beyond the obvious SCR and other strategies to extend our gas, this scenario means for us to make our exit quickly and efficiently. 3rd, the diver has encountered a caustic event or an injury, requiring a rapid egress towards decompression and to the door. In the #2 scenario would the diver remove things placed into the system? Say a guideline or jumps? The technical diver should have adequate gas planning to calmly end the dive and perform the planned decompression with no emergency because the gas requirements should be more than adequate to end the dive. #3 scenario is under extraordinary circumstances such as a caustic burn where the diver’s gas consumption is much higher than anticipated thus the diver is consuming more gas. Combined with the elevated gas consumption and the diver’s injury, the diver will require that the exit be as efficient and quick as possible, while performing all required decompression obligations.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/33ed52eb7be09dc6f1421349bda75fe3b9c8c056_divesoft-photo-045.jpg)  \nBailout systems are the backup system so that in the event of a failure a diver can safely exit back to the surface. Technical divers are trained from the beginning to always have a backup system in the form of a redundant gas delivery system combined with conservative gas management strategies. For OC tech diving in caves we follow the rule of 1/3rd gas management which is arguably not conservative enough in the event of a system failure but is still quite standard practice. The 1/3rd of gas is typically never used unless an emergency occurs. With Rebreather divers they are all often technical minded and the secondary OC system referred to as  “bailout” is often untouched unless incorporated as a diluent gas through offboarding which is quite common practice in cave diving. \n\nPlanning for our bailout in rebreather diving is not an overly complicated endeavor. We calculate how much gas is required for our planned range and decompression obligation, simple enough, right? The biggest problem is that most divers like to let their ego get in the way and base their gas planning on an ideal gas consumption on a normal day ( I know I’ve had to learn this the hard way). Oftentimes we don’t practice OC diving enough for us to maintain our good practices and good gas consumption, isn’t that the reason why we got into CCR diving?? Then in the event we do have a rebreather failure and have to go on OC it’s often not in the best conditions and we need to get our butt back to the door.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/a0d92a14d52aa2d3ff88bc1f538f0b05be3ac534_divesoft-photo-117.jpg)  \nBreathing is elevated, a flooded rebreather is throwing off any and all trim, stress, kicking yourself thinking how could you have taken the loop out of your mouth! All of this brings up the wonderful RMV that you were once so proud of. This scenario is just an example of making a mistake and flooding the rebreather. Now if this was a flood on a SM unit - this could quickly lead to a caustic event, now you’ve got an entire myriad of problems, throat spasms, coughing/gagging just to name a few.\n\nThe reality is you need to plan for an “Oh S***” moment, bailout and get your butt back home. Let's put some numbers down and say I normally plan for a .7 cuft RMV, then what I will do is plan for that initial bailout moment at a 1.5 cuft RMV, for 5 min, maybe 10 minutes, then I will settle down (all while moving towards the door) and bring my rate back down to a .7 RMV until I get to my decompression gas.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5d3c50390897

27662655bd048f84503d058a5d98a_divesoft-photo-079.jpg)  \nBailout procedures are very site specific and mission specific. Daily conditions can often have a significant impact on the divers' bailout strategy. This could mean an additional buffer of gas, perhaps using an Al80 for oxygen rather than an Al40 but it should always be scrutinized and constantly be reevaluated, especially when things have never been a problem, because that's when we should practice a bailout and see how we do. The old adage of practice makes perfect is good, but perfect practice makes better. Remember, every day we have an opportunity to be a better diver!\n\nAuthor: Joseph Jonathan Bosquez","showTags":false,"showDate":false,"image":{"mimetype":"image/jpeg","size":859850,"hash":"fe689d09a3326c556d872fb1e5453a43df5f2d1a","id":"clw4thkz2wv4q0776gz9lbmsz","filename":"divesoft-photo-079-bailout-procedures.jpg","category":"divesoft/","type":"image","dynamiclySourcedImage":" "}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#6","type":"component","lock":false,"position":2},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":6}],"id":"root","idBuffer":"#7","lastCommit":"44739586-ed80-4d9b-95fe-6ea24c7ea3c8"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:clxa0ibm1qtls07356bxbmpc2":{"id":"clxa0ibm1qtls07356bxbmpc2","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[{"type":"id","generated":false,"id":"Tag:cjv3szrcv01bz0836yo8myb0r","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:clyyc8ovoy9ai0735du6cmw7i","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww0t651b710803pcl02cn4","typename":"Tag"}],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:clxa0ibmkqtlz0735cwt023nr","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:clxa0ibmkqtlz0735cwt023nr":{"id":"clxa0ibmkqtlz0735cwt023nr","name":"A Comprehensive Guide to Technical Dive Planning / Part 1","createdAt":"2024-06-11T06:19:39.740Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

A good plan can be the difference between a great experience and disaster.","content":"Let's face it, every dive is actually planned. Even simply agreeing with a friend that you're going diving at Swan Lake and meeting at 5:00, is a plan. What is crucial, however, is the level of detail, sophistication and care that goes into preparing the dive. This will vary with the difficulty of the dive and the various conditions that come into play. Putting two extreme examples against each other, the level will be dramatically different for a routine recreational dive versus a challenging technical expedition to an unexplored site in a remote area. Contrast a few minutes of deliberation between two friends versus a year's preparation by a multi-person team. Let's focus on the **plan for a technical scuba dive without the support of a dive center**, which often solves many things for us.  \n\nSo let's go through the different elements that each plan should contain. If possible, all team members should prepare the plan together or at least consult with each other. If only one, usually the most experienced team member or event leader, is preparing the plan, he or she should thoroughly brief the other team members on the plan during a joint briefing. Team members must then demonstrate that they are familiar with the plan, understand it and understand their role and assigned tasks.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/ff955ff2e12ebba4c9231e5924e35b53ca500ee3_divesoft-photo-061.jpg)  \n\n**Location and weather**  \nSometimes the choice of the place is clear and we plan everything else around that, and other times we put together criteria of what we would like to see, experience, discover and what we have available. If we choose a place in the latter way, we have to turn to literature, maps or specialised websites with a database of sites. The location of wrecks can be guessed by local fishermen who repeatedly lose their nets in the same place. They also have an idea where marine life is concentrated. Local people such as herders, farmers or foresters, who know the area intimately, can help find new caves. Places that are still hidden from our community but that locals have knowledge of, are still plentiful even in today's modern world.  \n\nNautical charts can give us a rough idea of what the bottom relief looks like. Today 

2we can find some online, such as Navionics ChartViewer.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/139394a32c3880eec25b96f83b16c94f15da0b1c_blog-navionics-1.png)  \n\nIf we have information about a site from a source such as a list of dive sites, a description from someone who has dived there before us, and so on, we can then extract as much information as possible on things such as depth, location, prominent features and landmarks, access to the site, and possible hazards.  \nThe weather can be tricky and can make the event very difficult or even impossible. We need to have long-term and detailed short-term local forecasts. The long term is mainly concerned with choosing the right time of year to hold the event. We can easily find out the average temperature and precipitation in each period, periodic precipitation and winds, tidal forces, currents. In short, to choose the most suitable time of the year for the planned diving. Local short-term forecasting has been greatly facilitated by weather apps and websites such as Yr.no or Windy.com. \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/271c03a7871484edbfd054552ffb57cad77e3981_blog-windy-1.png)  \nEspecially the latter can display a huge amount of detailed data about the current weather situation anyw

2here in the world and forecasts for 9 days ahead, which includes wind, precipitation, waves, currents, tides, sea temperature (at the surface) and more. We have to take into account that there is no perfect forecast. We can consider a forecast up to a maximum of 24 hours ahead as relatively reliable data, while we consider data up to three days ahead as a probable course. Anything beyond the three-day horizon can only be accepted as a rough guide.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/905dbcee4d5ec2657499ddb1cf186ba8e15cb0e7_blog-windy-2.png)  \n\nThe exception is the tide forecast. There, on the other hand, iron-clad regularity and predictability apply. It is, however, very strictly location-specific, and so we must obtain tide tables as close as possible to the location of the planned dive. Timing the dive so that the tidal currents are as small as possible and flow in the right direction during the dive is essential. This is done at the peak of the tide.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/46ab9f0dfe4aea3c761d74fa99cd5b3a2ba82cfc_blog-tide-chart-1.png)  \n\n**Logistics**  \nLogistics is usually the least attractive part of the planning and the event itself. We have to take into account all conceivable operations necessary to carry out the event. Especially how to get to the site, how to get all the equipment there, where to stay, where to rent a boat, where and how to fill the bottles, and so on. The logistics of the dive itself then include deploying the progress or decompression cylinders, providing a decompression ladder, ascent rope and such.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/37b8e9ceda77f08a5d5266a2fc4f4b5193914a1f_divesoft-photo-010.jpg)  \n\n**Teams**  \nThe basic prerequisite for forming a technical scuba diving team is ensuring sufficient skills, experience and qualifications of all members. Events of a technical nature are often announced with a certain minimum level/qualification required. Where practical teams are divided into support and exploratory teams. Cave diving especially in Europe often requires an extra large team of porters. These do not even have to be divers themselves but must be proficient cavers and climbers. All equipment must be carried through miles of passageways, rarely upright and often by crawling, climbing, rappelling and traversing. This determines the ratio of porters per diver. On a recent historic crossing of a 7 km section in the Moravian Karst, there were 40 dry support team members to two cave divers.  \nThe underwater support team is responsible for deploying the progression cylinders and transporting all the necessary materials and technical diving equipment to the right places and removing those no longer needed. This allows the exploration team to concentrate on reaching the target or making new discoveries.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/43d91384968f50b68ebe55ba73da4fb2542dc8a2_divesoft-photo-072.jpg)  \n\n**Choice of technical diving equipment**  \nWe use the information about the location and difficulty of the dive to choose the equipment we will need. It would be nice if we could always use the same equipment for all types of dives, but that is simply not possible, despite the beliefs of some fundamentalists. Or at least not yet.  \nWe must first determine the basic equipment configuration. Will it be open circuit or closed circuit? Backmount or sidemount? Dry suit or wet suit? You say to yourself, if I have all that available, why should I choose in the meantime, I'll take the better one, but that certainly doesn't have to be the case. While rebreathers may seem to do all the work, for conditions such as a challenging cave transport to cross a siphon, lightweight self-contained steel cylinders are probably more appropriate. For deep dives closed circuit. For dives with long underwater penetration of a cave or wreck or extreme depths many progression or decompression cylinders, a double rebreather or bailout rebreather are suitable, for narrow spaces a sidemount rebreather. The amount of cylinders and gases then follows from gas management planning, which we discuss below.  \nFor the basic configuration of technical equipment we have to think about what additional equipment we will use. Guide lines, buoys, reels, spare lights, spare cutters, heating systems, scooters, transport bags and boxes, and other technical diving gear.  \nSome missions require very specific tools and pieces of equipment designed for specific purposes. Biologists like Sonia Rowley or Richard Pyle need trap nets, sampling vials. Other times divers need mapping plates, but also hammers, crowbars, saws, metal detectors, markers, dye

2s, and so on.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/85f53de0e832db381655bf016329c4ba3816463c_divesoft-photo-108.jpg)  \n\n**Dive objectives**  \nHa, this is probably the most fun and adventurous part of the planning. We're discussing with our friends what exactly we're going to do underwater and how the dive will work. We have a map of the site, cave or wreck in front of us and we think about how best to execute the dive. Everyone is assigned their tasks and responsibilities within the team. A timing plan of specific steps to take while on the bottom is made. The exposure will then be determined from that. That is, the depth and time of the dive. These are the necessary inputs for planning decompression, gas management, gas selection and setpoints.

In the second part of the article we will focus on planning the dive itself. That is, everything you need to plan for staying safely underwater and returning to the surface.","content":"**Decompression**  \n\nIt will soon be 120 years since the publication of the first Haldane decompression tables and we are still not very clear on the issues that are most typical for diving activity. According to recent research, it seems that algorithms generating deep stops are out of date and the best we have is the Bühlmann model modified by gradient factors. The choice of the gradient factor is already the first step in decomposition planning. Current trends show that the safest and most effective is to use a GF low in the range of 40 - 50 and a GF high of 60 - 80. What you set in your planning app and your dive computer will affect the depth of the first stop (GF low) and the level of tissue saturation on surfacing (GF high).   \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c737a0b6eb8800e27cd50e828e4225f2b2e6c9dd_guide-to-technical-dive-planning-part-2-decompression.png)  \n\nSpeaking of scheduling apps, that's the current modern trend. After the use of spreadsheets and planning software on the desktop computer comes mobile phones, which are now more powerful than PCs in the days of the first decompression software. Mobile phones are always at our fingertips and their operation is easy. Divesoft.app has an advanced scheduler that is continually improved. You choose whether you plan for open or closed circuit, set all the parameters and enter the dive profile, i.e. maximum depth and time. The app takes into account the subtle nuances of personal customisation of the planner. It is also possible to customize the profile for multi-level dives by adding additional points to the chart. This makes it suitable for advanced cave dives with multi-level depth profiles.  \n\nA bailout plan is available in CCR mode. This is a must for planning with a rebreather, because decompression on the open circuit at a moment at which you can no longer dive with CCR due to a failure, is usually longer and you consume a significant amount of gas. You can further adjust the plan to make it acceptable and feasible in the planned conditions.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c80f20b8f5d2b4541f0994d21cd108dc10e52be0_divesoft-photo-063.jpg)  \n\nOnce you are satisfied, you can transfer the plan to a .pdf format using the Print function and print the plan by sending it to the printer. You can take this plan underwater with you and follow it.  \n\nIn any case, every technical diver should have an understanding of the ratio of time to surface at what depth and be able to derive the decompression time off the top of their head. Some people use this as a basic method and software just to confirm, but it can work the other way around. In any case, it comes in handy when the decompression computer fails.  \n\n**Gas management**  \n\nThe amount of time we can spend at the bottom is determined by the amount of gas we have available. Everything can be planned by calculations on paper or by entering it into a dive planning app, where it is easier and infinitely faster.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/eb1f5c8c16157cc089fcfd133838a260f8b0d70a_guide-to-technical-dive-planning-part-2-gas-management-oc.png)   \n\nWhen planning an open circuit dive, we have to take into account that we always have to get to the surface safely even if we or a team member runs out of gas at the worst possible moment, i.e. at the end of the planned time on the bottom. Above all, we must know the minimum amount of gas we need to surface. We take into account that we will be breathing two from one apparatus and under stress, so we have to add our partner's consumption to our own and multiply it by the stress factor of 1.5. We must not forget to multiply the result by the ambient pressure. We calculate the output until the first gas switch, where the partner switches to decompression gas and therefore has their supply. We can be conservative and calculate the pressure of the maximum depth, or we can be more realistic and calculate the average pressure between the maximum depth and the depth of the first gas switch. Let's take the example of a dive to 60 m with a gas switch at 21 m. The pressure at 60 m is 7 atm, at 20 m it is 3 atm. The average pressure will therefore be (7+3) / 2 = 5 atm.  \n\nMy consumption is 15 l/min.  \nPartner's consumption 15 l/min  \nStress coefficient 1.5 ×  \nCalculation: (15 + 15) × 1.5 × 5 = 225 l/min  \nAscent time from 60 m to 21 m at 10 m/min = 4 minutes  \nCalculation: 4 × 225 = 900 litres.  \n\nOn the bottom, however, we'll probably deal with a crisis situation and shoot a buoy to the surface, for example. For this reason it is a good idea to allow some extra time, at least 3 minutes. That's 3 × [(15 l/min + 15 l/min) × 1.5 × 7 atm] = 945 litres  \n\n900 litres is the amount of gas we will need to ascend to 21 metres, where we will switch to decompression gas, and 945 litres are needed to deal with the situation at the bottom, so 1845 litres in total. If we have 2×12 litre cylinders, that's 77 bar in the cylinder that we have to start surfacing with. 123 bar is therefore available for the dive itself, which is enough for us at 60 metres:  \n\n(123 bar × 24 l) / (15 l/min × 7 atm) = 28 minutes  \n\nWe count decompression cylinders separately. Here we calculate the simple c

2onsumption.  \n\n**Gas management for CCR**  \n\nIn the case of closed circuit diving, gas management is simple for CCR and the bailout bottle remains unused.  \n\nOxygen consumption is simply the dive time × 1.5 l/min. Although the physiological consumption is lower, we have to calculate the gas losses associated with the dive.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/8532ba08649962e452c00dad10a99b7ea15ded81_guide-to-technical-dive-planning-part-2-ccr-plan.png)  \n\nThe diluent consumption depends on the loop volume and the depth of immersion, or repeated descents. If the profile is simple, we can calculate the loop volume multiplied by the pressure. For a more realistic result, we multiply by two to account for gas losses during small changes in depth.  \n\nMore challenging and critically important is gas management planning for the bailout. We have to take into account that a bailout will happen at the worst moment of the dive, i.e. at the end of the planned time on the bottom at maximum depth. We add again 3 minutes to solve the problem.  \n\nThe question is what consumption to choose. Since this is a really critical situation where we have to switch from CCR to OC and CO2 hit is in play, we calculate a consumption of 50 l/min. This applies for at least the first 10 minutes of the rescue plan.  \n\nSo we count the first 3 minutes on the bottom, let's say again at 60 meters:  \n\n3 × (50 l/min × 7 atm) = 1050 l  \n\nAscent to 21 m takes 4 minutes and the average pressure is 5 atm: 4 × (50 l/min × 5 atm) = 1000 l  \n\nTo climb to 21 metres, we need 2050 litres, which is equivalent to one Al80 bottle.  \n\nNext, we have 3 minutes left at a consumption of 50 l/min and the rest is calculated with a consumption of 25 l/min. This is a realistic calculation, as CCR divers easily lose their low consumption capabilities as they can breathe as much as they want with CCR, and their transition to OC is often accompanied by an unpleasant surprise at how much gas they have exhaled.  \n\nAnother interesting element of the bailout plan is that we choose a conservative PO2 value on the bottom with CCR, and the subsequent decompression is actually longer than if the same dive had been done with OC.  \n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/26e887b9b2846093b7201c1bf9d6d3ab098b3c19_guide-to-technical-dive-planning-part-2-ccr-bailout-plan.png)  \n\nCalculating the consumption at all decompression stops can be rather tedious, so it is more convenient to use a scheduling application. Divesoft.app assumes that the diver is using a stock of bailout gases that they do not change, so the app has a virtual stock of cylinders that the user uses most often. He then chooses from these cylinders when planning the dive, but of course he can add or change any other mixture during the planning process. \nIn the application settings, you can also set the length of time to solve a problem, the consumption in a critical (stressful) situation, the length of a stressful situation and the consumption outside a stressful situation. The app then calculates everything for you.  \n\n**Selecting Mixtures and Setpoints**  \n\nChoosing a mixture is always like walking a tightrope. We have to balance over dangerous precipices, and we don't want to fall into any of them. Those chasms have names like decompression sickness, oxygen poisoning, nitrogen anesthesia and gas density.  \n\nThe first question should be: how much oxygen? The answer might be as much as possible, which is partly true. We metabolize oxygen, so it doesn't contribute to decompression sickness (quite the opposite, in fact), so the more we have in the mix, the less inert gases we'll suck into our tissues, and the less decompression duties we'll have.  \n\nOn the other hand, there must not be too much of it, lest we endanger ourselves with oxygen poisoning. We must carefully consider the exposure time to determine the maximum partial pressure of oxygen (PO2 ). The NOAA table of CNS oxygen exposures will help us to do this. This table is not very exact, and we suspect that many things are a little different, but it is the best we have for now.  \n\n**PO2 (bar)**\t/ Single dive exposure (minutes)\t/ *24-hour exposure*\n(minutes)  \n\n**1,6**\t/ 045 / *150*  \n**1,5*

2*\t/ 120\t/ *180*  \n**1,4**\t/ 150\t/ *180*  \n**1,3**\t/ 180\t/ *210*  \n**1,2**\t/ 210\t/ *240*  \n**1,1**\t/ 240\t/ *270*  \n**1,0**\t/ 300\t/ *300*  \n**0,9**\t/ 360\t/ *360*  \n**0,8**\t/ 450\t/ *450*  \n**0,7**\t/ 570\t/ *570*  \n**0,6**\t/ 720\t/ *720*  \n  \nIn the case of an open circuit, maximum PO2 for the mixture at maximum depth and PO2  for decompression. This partial pressure will only ever be reached at maximum depth and will decrease with decreasing depth. With the circuit closed, however, the partial pressure remains the same all the time (until we switch to a different setpoint), in which case the oxygen exposure is much more severe. Hence, with a rebreather we always choose much more conservative values. While with OC we can expect a PO2  of 1.4 on the bottom and 1.6 on decompression, with CCR the maximum PO2 will be 1.2 on the bottom and if the total dive length allows it, we can get up to 1.4 on decompression. Of course we are talking about the preset setpoint. The actual mixture should be 0.2 bar PO2 lower still at the target depth so that we have enough reserve to dilute the loop in case of trouble.  \n\nSo how do we find out how much oxygen should be in the mixture? By a simple calculation of Dalton's law. We calculate the absolute pressure at the maximum depth.  \n\nF = PO2  / P  \n\nFor example, for a depth of 60 m and a selected partial pressure of 1.4, calculate the oxygen fraction as follows:  \n\nF = 1,4 / 7  \nF = 0,2  \n\nWe then find that for a depth of 60 m we use 20% oxygen in the mixture.\nFor closed circuit diving, the pattern remains the same of course, but we have different entry criteria. In particular, the maximum PO2 will be 1.2 bar. But we also have to ensure that the total gas at depth is dilutable. It is therefore advisable to select a maximum PO2 of the mixture that is 0.2 bar lower than the setpoint. In our case, 1 bar.  \n\nF = PO2  / P  \nF = 1  / 7  \nF = 0,14  \n\nThe proportion of oxygen in the diluent will be 14%.  \n\nThe CNS oxygen toxicity breaks down by 50% every 90 minutes and this should be taken into account when planning repeat dives.  \n\nIn addition to CNS oxygen toxicity, we have whole-body toxicity arising from prolonged exposures even at lower POs2 . We calculate it in OTU (oxygen toxicity unit). One unit of OTU is produced by a minute exposure to PO2 1.0. A daily limit of 300 OTUs is set for whole body toxicity. If we were calculating the entire OC dive, we would have to take the individual levels at each PO2 level and add them together.  \n\nFor example, a dive to 60m for 20 minutes on a mixture with 20% oxygen and decompression to EAN 50 from a depth of 21m. We already know that the PO2 at the bottom is 1.4 bar  \n\nOTU bottom 1,4 × 20 = 28  \nOTU output (average pressure 5 bar) (5 × 0.2) × 4 = 4  \nOTU deco 21m 1,5 × 4 = 6  \nOTU deco 18 m 1,4 × 2 = 2,8  \nOTU deco 15 m 1,2 × 1 = 1,2  \nOTU deco 12 m 1,1 × 3 = 3,3  \nOTU deco 9 m 0,9 × 5 = 4,5  \nOTU deco 6 m 0,8 × 22 = 17,6  \nTotal OTUs = 67.4  \n\nIt is clear from the previous calculation that whole body toxicity does not play a very significant role in open circuit diving. However, it is different in rebreather diving. If we perform the same dive with CCR, the OTU calculation will obviously be much easier, and let's see what it does to the result. Let's take a setpoint of 1.2 bar on the bottom and 1.4 on the decompression.  \n\nThe time at setpoint 1.2 is 20 minutes and according to the decompression planner the total output at setpoint 1.4 is 39 minutes.  \n\nOTU bottom 1,2 × 20 = 24  \nOTU decompression = 1.4 × 39 = 54.6  \nTotal OTUs per dive = 78.6  \n\nWe can see that a separate dive won't affect us much. The problem may arise in the case of repeated dives. When diving with a CCR at an attractive site or expedition, where several dives a day for a week or more are dived, the whole body form of oxygen toxicity may already be a problem that must be seriously taken into account.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/df7e4945aff05edf3248e495ac46155e4ce49de6_guide-to-technical-dive-planning-part-2-oc-graph.png)  \n\n**Clean head**  \n\nOnce we have our oxygen, we then need to focus on making sure that at each dive depth our cognitive, mental and reactionary abilities are as little affected as possible by the narcotic effect of inert gases at high pressure. If we are diving with air on an open circuit, we can say that at a depth of 30 meters our mind is still acceptably efficie

2nt. So we will take this depth and relate our calculations to it. We will call this depth the equivalent narcotic depth (END).  \n\nSo we need to find out what the partial pressure of nitrogen is at those 30 meters with air:  \n\nPN2 = FN2 × P  \nPN2 = 0,78 × 4  \nPN2 = 3,12 bar  \n\nTo be even more conservative, we can use the simplified 3 bar PN2, which corresponds to a depth of 28 m.  \n\nIf we want to find the amount of helium in the mixture, we can actually add the sum of the maximum partial pressures of oxygen and nitrogen, and subtract it from the ambient pressure at the maximum depth. So if we use the 60 meter depth from the previous examples, it will look like this for planning the OC of the mixture:  \n\nPHemax = P - (PO2 + PN2)  \nPHemax = 7 - (1,4 + 3)  \nPHemax = 2,6 bar  \n\nAccording to the already known formula we calculate the fraction of helium  \n\nFHe = 2.6 / 7 = 0.37  \n\nIf we take all the information together, we get a trimix 20/37.If we wanted to use a standardized mixture, we would go for the closest one, which is trimix 18/45.  \n\nOn the other hand, if we add too much helium and still use helium penalties, which I don't want to go into, the decompression software will unnecessarily increase the decompression time.  \n\nIf we use the same procedure to calculate the mixture for the diluent, where we want a maximum oxygen partial pressure of 1 bar, we arrive at a mixture of trimix 14/43.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/adbd8c4a15bc716e89a2dcb620bd10c901fb7dcb_divesoft-photo-101.jpg)  \n\n**Rescue and evacuation plan**  \n\nLast, but certainly not least, the most important element of planning is to think through the rescue and evacuation plan when things don't go as they should. We would prefer to tuck away the fact that a tragic or very dangerous event may happen as deeply as possible or even erase it altogether, but that could backfire badly. If we already have an advance plan of what to do at what time, what first aid, CPR or technical rescue equipment we will need from a given location, where to call in an emergency, where to take an injured or disabled DCS, it will make things significantly easier when something serious actually happens.  \n\nMake sure you have an adequate supply of oxygen and all CPR supplies in advance. If you can get an AED the better for you. Consider using a stretcher to get the casualty out of the water, scooters to get the casualty to the boat or shore.  \n\nFind out all safety contacts for paramedics, decompression chambers and insurance companies. Secure locations for arrival of rescue personnel, identify possible helicopter landing sites.\nThere are many options to consider and it is up to each team to think carefully and prepare.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/48f1271a84ff6add1b8ec0f856a16ffaea59e893_divesoft-photo-046.jpg)  \n\n**Conclusion**  \nPlanning a technical dive is a very complex matter and technical diving cannot be done without planning. If you dive the same sites repeatedly with the same or similar exposures, the plan can be used repeatedly and over time will become routine. However, one must never forget to update such a plan. The technical diver must be first and foremost.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/ef29aa5adb944df75a8077ef585977cc5e6f6fb7_divesoft-photo-128.jpg)  \n\nAuthor: Jakub Å imánek","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":969448,"hash":"bc909a55cf9f2b36f7d736b271f626c5f51b7a74","id":"clye9bswknh0s0776i5dedmrb","filename":"divesoft-photo-062-1.jpg","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#21","type":"component","lock":false,"position":2},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/@divesoft_tv","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]","twitterUrl":{"url":"","urlNewWindow":true,"pageId":"cjv3l26tp004p0836i54n4u7a"}},"id":"#1","type":"component","lock":false,"position":3}],"id":"root","idBuffer":"#22","lastCommit":"429a9605-194f-4e6b-b5e5-4c93fc37faf4"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"}

Nezná vaše konkrétní fyziologické požadavky na dekompresi. U každého profilu ponoru vždy existuje riziko dekompresní nemoci (DCS), i když dodržujete plán ponoru předepsaný potápěčským počítačem. Žádný postup, potápěčský počítač ani potápěčská tabulka nezabrání možnosti vzniku DCS nebo otravy kyslíkem!  \n<span style=\"color:red\">Upozornění</span>: Používejte záložní nástroje! Zajistěte si přístup k záložním přístrojům pro měření hloubky a času. Zajistěte si přístup k záložní metodě výpočtu dekompresního profilu. Nikdy neriskujte svůj život pouze na základě jednoho zdroje informací.  \n<span style=\"color:red\">Upozornění</span>: Před potápěním vždy přístroj zkontrolujte, zda funguje displej, zda se nevybila baterie a zda jsou všechna nastavení správná.  \n<span style=\"color:red\">Upozornění</span>: Každý software obsahuje chyby a firmware Divesoft Freedom není výjimkou. Počítač může pravděpodobně dělat nechtěné věci.  \n<span style=\"color:red\">Upozornění</span>: Tento počítač se může kdykoli porouchat. Otázkou není, zda se porouchá, ale kdy se porouchá. Vždy mějte plán, jak se s poruchami vypořádat.  \n\n**Odpovědnost uživatele Divesoft Freedom**  \n\nUživatel Divesoft Freedom musí přijmout skutečnost, že potápění je spojeno s rizikem. Dodržování všeho, co se uživatel dozvěděl z technické dokumentace Divesoft Freedom a z výcviku, může riziko snížit, ale nemůže ho odstranit. Bezpečnost při potápění dále zvyšuje pravidelné školení, metodické vzdělávání a dodržování správné potápěčské praxe. Technické potápění vyžaduje mnohem vyšší míru opatrnosti a disciplíny než rekreační potápění.  Pokud toto riziko neakceptujete a nejste vyškolení, opatrní a disciplinovaní potápěči, nepotápějte se s přístrojem Divesoft Freedom.\n\n\n","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#3","type":"component","lock":false,"position":5},{"name":"Divider","data":{"color":"darkGray"},"id":"#15","type":"component","lock":false,"position":6},{"name":"TextBlock","data":{"text":"### <span id=\"upgradable-computer\">**Počítač s možností upgradu**</span>  \n\n**Vlastnosti verzí Freedom**\n\n\tVerze                 Směsí  Air  Nitrox  Kyslík  Trimix  Rebreather\n\n\tAdvanced Bottom Timer   -         -    -       -       -       NO  \n\tCCR Bottom Timer        -         -    -       -       -       Yes\n\tBasic Nitrox            1         Yes  max40%  No      No      No\n\tAdvanced Nitrox         3         Yes  Yes     Yes     No      No\n\tFull Trimix             9         Yes  Yes     Yes     Yes     No\n\tClosed Circuit          9+8 dil.

In regards to ice diving this is pretty obvious but what about that range from frozen to warm? ","content":"Cover photo: Petri Laaksonen - Montala mine, Finland\n\nMany of the training agencies and organisations define it as less than 15°C but many would argue that is still pretty temperate and that it should be lower before being considered ‘cold’. I guess it depends on your opinion and what you are used to. One warm water diving friend that came to Sweden for an early season trip, when finding out that the water temp was 3°C asked ‘What is the other missing number?’. Needless to say he was a bit wide eyed when informed there was a 0 but it was in front of the three.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/79602daa242d3948b69aa9394b8baf2854ba138c_edd-stockdale-cold-water-diving-02.JPG)\nPhoto: Tiffany Norberg - Kitting up on the Baltic Sea\n\nFor the purposes of this article, and the fact that I predominately dive in less than 10°C, we will call cold 6°C and less, as the core topic here is handling the conditions not only underwater, but also on land, so let’s look at why this article has even been written and what is challenging in regards to these conditions.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/90fc19eb1429c501830a13a7c45a77e475bc10b4_edd-stockdale-cold-water-diving-03.JPG)\nPhoto: Tiffany Norberg - getting ready for winter diving in Swede

2n\n\nTo begin let’s consider the fundamental consideration with diving in cold water, staying warm, both on the surface and underwater. Drysuits are basically a must in modern diving for this environment as are suitable undergarments to stay warm. These are often very bulky, though comfortable, and require more weight depending on the purpose. The big key consideration is the wicking ability of anything worn under a drysuit. It must remove moisture from the body away from the skin and as such the primary rule is no cotton or material that attracts water, especially against the skin. In addition to this, you will sweat in the suit while moving around on land so to make life nicer, a good base layer that wicks moisture fast but can also be cleaned easily makes your cold water experience more enjoyable. I would recommend a merino wool base layer, then a suitable thicker layer on top and maybe a middle layer if diving in even lower temps or on longer dives. While warm you also need to consider the range of movement as you still need to reach valves, swim, and have a range of freedom, so the actual drysuit may be bigger in size than a warm water suit. I have a multiple suits for different temperatures and diving ranges which have room for this base layer. \nA big component of diving in these conditions is staying warm prior to diving. Wear suitable clothing, gloves and a hat that keep your extremities warm before even getting changed to go in the water, as they will not warm up after you have. \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/ebad199cce1fa8420fbea9389b5951a5f35bdfd9_edd-stockdale-cold-water-diving-04.JPG)\nPhoto: Marcin Wojturski - Ready for a 6 hourmine exploration dive\n\nWhat about heating? It is great in these conditions, but again comes with its own challenges and issues. The first consideration is getting a system where the battery is external to the suit. Pressure increases reaction rates and if you get a rapid increase or burn you cannot turn off an internal system. The same applies to chemical heating pads, do not use them diving or you will get burned. With heating you need to consider the physiological effects as well related to decompression and complications caused if for example your battery fails on ascent so you get colder during that phase. Often many divers will use their heating later on in a dive when getting cold, or during ascents to offset this risk, but not always; sometimes it’s just nice to stay warm on shallower dives.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/084b0df96e4e02ae0df000170a603c29f3dbbf3c_edd-stockdale-cold-water-diving-05.jpg)\nPhoto: Edd Stockdale - Getting gear ready for a dive\n\nIt’s not only you that needs to stay warm as well, so does your diving gear. Due to the very nature of  diving, equipment is not really designed for sub 0°C temperatures and freezing. If diving open circuit you have the risk of free flows when opening regulators in cold conditions on the surface and of drawing to much gas underwater, even in 2-6°C. As such pre dive checks and protocols need to be slightly different while still testing everything. Ensuring your gear spends the minimum amount of time standing in low temps, testing functionality in the warmth before heading to water, and no purging or breathing of regulators until in-water. When it’s -20°C surface temp we don’t even open valves until they are submerged.\nUnderwater itself you need to reduce high flow, breathe slower and use repeated small presses of BCD and drysuit inflation buttons instead of long fills.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/d6585740d75d58beee3f13787338877779f879a6_edd-stockdale-cold-water-diving-06.jpg)\nPhoto: Edd Stockdale - Diver in the Arctic ready to jump into the ice hole\n\nRebreathers in the cold, while having huge benef

2it with warm gas returning for inhalation helping maintain body heat, also have careful considerations, most critical of which is the CO2 absorbent. Chemical reactions slow down when cold and this applies to the rate at which scrubbers work, so reduced usage of time compared to warm conditions is important and needs to be considered when planning dives.  In addition all the electronics, both on the CCR, and also other items get effected as well. Batteries run shorter times, pressure sensors can get damaged by water on them freezing (common issue with dive computers and handsets that have sensors on them) and plastics/ O-rings become more brittle and can crack. Consideration of the model of CCR for the conditions they are designed for is important as well, both for resilience to the conditions and operational design, for example use with heavy dry gloves. \nHaving seen a neck seal of a drysuit freeze and crack you can imagine what can happen to other items.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/9dd19bbc5dc11f08a9bcab3f34c11d246de0b5d2_edd-stockdale-cold-water-diving-07.png)\n\nSo with all this trouble and cold, why go diving in it at all? Cold water environments are often amazing regardless of whether you are a nature diver, wreck enthusiast or an overhead junkie. It is a different fascinating world which, while challenging, can offer an entire new aspect to your diving. Granted you will have to get some specific equipment, learn how to use everything with dry gloves and change some of your protocols, but you will have the opportunity to see places less visited, greater preserved wrecks or mines, and amazing wildlife. \nHuge development in drysuits, active heating, CCR technology and batteries mean what was once a more obscure area of diving is now becoming accessible to even the most warm water diver. \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7ba26b6fa68f4bb4e218e4dc39e4687a2d68f7bb_edd-stockdale-cold-water-diving-08.jpg)\nPhoto: Alf Norkko - Survey of seagrass beds in the Gulf of Finland\n\nHopefully you get to try it soon.\n\nAuthor: [Edd Stockdale](https://www.divesoft.com/en/ambassadors/eddstockdale)","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":2837951,"hash":"95442fc28ed32d2e63459df271a5efb3779640ae","id":"clz859d5www1u077612z7likn","filename":"edd-stockdale-cold-water-diving-01.jpg","category":"divesoft/","type":"image","alt":""}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#21","type":"component","lock":false,"position":2},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/@divesoft_tv","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]","twitterUrl":{"url":"","urlNewWindow":true,"pageId":"cjv3l26tp004p0836i54n4u7a"}},"id":"#1","type":"component","lock":false,"position":3}],"id":"root","idBuffer":"#22","lastCommit":"e285756c-cfea-4f34-a70d-d64b15d8e3cf"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cm0az5m5s0t9b0818fxjonef0":{"id":"cm0az5m5s0t9b0818fxjonef0","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cm0az5m690t9i0818ann3i2av","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cm0az5m690t9i0818ann3i2av":{"id":"cm0az5m690t9i0818ann3i2av","name":"CCR Liberty Manual CZ","createdAt":"2024-08-26T12:28:40.448Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

2kurzu akreditovaném výrobcem. Předpoklady pro absolvování školicího kurzu stanoví spolupracující agentury.\n\n**Odpovědnost uživatele CCR Liberty**\n\nPři vývoji zařízení CCR Liberty byl kladen velký důraz na spolehlivost. Vnitřní části jsou od sebe odděleny tak, aby se minimalizoval dopad, který může mít porucha kterékoli části na základní funkčnost rebreatheru. Několik systémů má několik záloh. Logika systému CCR Liberty spočívá v tom, že ovládací prvky nikdy nezakážou zahájení ponoru, a to ani v případě zjištění poruchy. Systém nikdy nezablokuje potápěče; místo toho systém indikuje stav jednotky s ohledem na případné poškození, pokud je toho schopen. Při [jeskynním potápění](https://www.divesoft.com/en/blog/ccr-liberty-cave-diving-resistance) může nemožnost ponoření znamenat nemožnost návratu z ponoru; proto systém CCR Liberty nebrání ponoření.\n\nJe vždy na odpovědnosti uživatele, aby se rozhodl, zda přejde na záložní přístroj, nebo se rozhodne zahájit ponor s částečně nefunkčním rebreatherem.\n\nUživatel přístroje CCR Liberty musí přijmout skutečnost, že potápění s sebou nese riziko. Dodržování všeho, co se uživatel naučil při čtení technické příručky CCR Liberty a během svého výcviku na rebreatheru, může toto riziko pouze snížit. Bezpečnost potápěče se zvyšuje pravidelným školením, metodickým vzděláváním a dodržováním správné potápěčské praxe. Potápění s rebreatherem vyžaduje mnohem větší míru disciplíny a uvědomělosti ve srovnání s potápěním s přístrojem s otevřeným okruhem.\n\nPokud toto riziko neakceptujete a nejste vyškolení, opatrní a disciplinovaní potápěči, nepotápějte se s přístrojem CCR Liberty.\n\nVýrobce nenese žádnou odpovědnost za používání přístroje CCR Liberty, pokud byl přístroj upraven jakýmkoli způsobem, který není uveden v tomto návodu nebo v technických pokynech vydaných výrobcem.\n\n**Dokumentace**\n\n**Verze**\n\nTechnická dokumentace podléhá procesu neustálého vývoje a zdokonalování. Proto pravidelně sledujte webové stránky na adrese [divesoft.com](https://www.divesoft.com/en), kde najdete aktualizace.\n\nTato příručka obsahuje návod k obsluze pro hardwarovou a softwarovou (firmwarovou) verzi CCR Liberty napsanou na titulní straně.\n\n**Technické pokyny**\n\nVýrobce může vydat technické pokyny. Důrazně se doporučuje, aby uživatel pravidelně kontroloval [divesoft.com](https://www.divesoft.com/en), zda nejsou k dispozici nové pokyny. Registrovaní uživatelé budou dostávat upozornění e-mailem.\n\n**Aktualizace dokumentů**\n\nElektronická podoba příručky je vždy k dispozici v kompletní, aktualizované podobě. Elektronická a tištěná podoba příručky nemusí být zcela totožná. V případě nepodstatných změn (například oprava drobných překlepů) je aktualizována pouze elektronická verze.\n\n**Podpora uživatelů**\n\nRegistrovaní uživatelé mají nárok na technickou podporu.

Obě CU mají přístup ke všem čtyřem snímačům kyslíku a neustále si vyměňují data.\n\nPotápěč může ručně vyloučit čidlo z provozu a může také zvolit, kdy jej znovu vyloučí. Volba ručního vyloučení čidla má vždy přednost před automatickou detekcí vadného čidla. Pokud jsou vyloučeny všechny snímače, lze CCR Liberty přepnout na záložní algoritmus s výpočtem parciálního tlaku kyslíku nepřímo na základě naměřeného obsahu He (za předpokladu, že použité ředidlo obsahuje >20 % He).\n\nPro přesnost měření je nutná cirkulace směsi v dýchací smyčce. Pokud uživatel nedýchá z rebreatheru, může mít směs v okolí kyslíkových senzorů jiný podíl kyslíku než v dýchací smyčce. Zobrazené údaje tak mohou být nepřesné.\n\nPodobná situace může nastat v případě rychlého sestupu, kdy je přidáno větší množství ředidla, nebo když je nastavená hodnota změněna na vysokou a ppO<sub>2</sub> v dýchací smyčce postupuje na novou úroveň.\n\nSenzory jsou neustále automaticky vyhodnocovány. Hodnota ppO<sub>2</sub> naměřená jedním senzorem je vždy porovnávána s průměrnou hodnotou ostatních senzorů. Tímto způsobem je každý jednotlivý senzor neustále křížově k

2ontrolován a sledovány případné odchylky. Pokud průměrná odchylka čidel překročí 0,1 baru, systém automaticky vyloučí čidlo, které se od průměru odchyluje nejvíce.\n\nV jednom okamžiku lze automaticky vyloučit pouze jeden snímač a celkem lze automaticky vyloučit pouze dva snímače.

Hloubka se vypočítá z naměřeného hydrostatického tlaku. Pro výpočet hloubky lze nastavit hustotu sladké (výchozí) nebo mořské vody (jednotky a slanost se nastavují v Nastavení → Předvolby).\n\nNastavení sladké/mořské vody nemá vliv na výpočet dekomprese. Dekomprese je založena na okolním tlaku a je nezávislá na zobrazené hloubce.\n\n**No deco**\n\nMůžete zůstat po uvedenou dobu v aktuální hloubce a dýchat aktuální směs (aktuální obsah He a aktuální SP), abyste se vyhnuli povinnosti dekomprese. Předpokládá se však, že potápěč bude dodržovat doporučenou rychlost výstupu.\n\nBěhem ponoru nastává situace, kdy indikátor No Deco již ukazuje nulovou hodnotu, ale hodnota dekompresního stropu se stále nezobrazuje. Taková situace může trvat i několik desítek sekund. Tento scénář je způsoben tím, že doba No deco skončila a dekompresní strop je pod úrovní hladiny, ale jeho hodnota je tak nízká, že není třeba provádět postupnou dekompresi, protože se doporučuje volný výstup.\n\n**Ceiling**\n\nHloubka dekompresního stropu se plynule snižuje až k hladině. Zobrazené zastávky nejsou nikdy náhodné. Vždy se držte pod hloubkou stropu, i když je hloubka stropu velmi malá.\n\nUkazatel stropu v Liberty nahrazuje ukazatel dekompresních zastávek. Potápěč si zvolí hloubku, ve které provede dekompresní zastávku, nebo plynule stoupá podle dekompresního stropu. Tento přístup může být efektivnější z hlediska doby dekomprese. Referenčním časem je TTS (Time To Surface - čas do vynoření). Nesledujte dekompresní strop v malých hloubkách, pokud to podmínky neumožňují. Vlny, proudy, pozitivní vztlak výstroje v malé hloubce, absence vizuální reference a další faktory mohou způsobit nekontrolovaný výstup nad strop nebo zcela znemožnit dekompresi na této úrovni.\n\nVýstup nad strop generuje výstrahu. Další překročení o více než 1 m (3 stopy) vede k dalšímu výstražnému signálu. Oba alarmy jsou zaznamenány. Výpočet dekomprese bude pokračovat bez penalizace. Je na potápěči, aby se rozhodl, jak minimalizovat pravděpodobnost vážných následků.\n\nDekomprese již není nutná, když zmizí hodnota stropu. V takovém případě je možné se vynořit.\n\n**TTS**\n\nDoba do vynoření (TTS) zahrnuje celý dekompresní profil. Zaokrouhlení TTS je ovlivněno nastavením v Menu / Nastavení / Dekomprese / Nastavení plánovače / Zaokrouhlení.

Například žádaná hodnota 1,3 ve 3 metrech může být dosažena, ale pouze pokud je ve smyčce 100 % kyslíku, ale pokud je FO<sub>2</sub> nastaveno na 80 %, pak se žádaná hodnota zobrazí žlutě a solenoid nebude přidávat kyslík tak dlouho, dokud hodnota ppO<sub>2</sub> neklesne pod 1,04bar \\[1,3×0,8\\].

Naměřený ppO<sub>2</sub> se upravuje podle matematického modelu dýchací smyčky. Výpočet dodávky O<sub>2</sub> a případného následného otevření solenoidu se provádí v šestisekundových intervalech. Kyslík se přidává střídavě pomocí solenoidů odpovídajících oběma řídicím jednotkám.\n\nV případě, že není možné určit skutečnou hloubku (z důvodu poruchy nebo ručního vyloučení všech tlakových čidel), přechází regulace dodávky kyslíku na jednoduchý algoritmus.\n\n**Setpoint**\n\nPožadovaná hodnota je požadovaná hodnota ppO<sub>2</sub>; informace o nastavení požadované hodnoty viz kapitola 2.4.2 Požadované hodnoty. Dvě speciální hodnoty, „nízká požadovaná hodnota“ a „vysoká požadovaná hodnota“, jsou pevně stanoveny. Ty lze jednoduše zvolit dlouhým stisknutím horního tlačítka (pro vysokou žádanou hodnotu) nebo dolního tlačítka (pro nízkou žádanou hodnotu).\n\nVe výchozím nastavení má nízká požadovaná hodnota hodnotu 0,7 bar (70 kPa). Je možné ji přenastavit v rozsahu 0,4 až 1,3 bar.\n\nVe standardním nastavení má vysoká požadovaná hodnota hodnotu 1,3 bar (130 kPa). Je možné ji vynulovat v rozsahu 0,7 až 1,6 bar.\n\nPři spuštění režimu potápění CCR je standardně aktivována nízká požadovaná hodnota.\n\n**Descent setpoint**\n\nNastavená hodnota sestupu je určena pro situace, kdy potápěč potřebuje rychle sestoupit do dané hloubky, například při potápění v proudu. Využívaný algoritmus využívá přirozený vzestup ppO<sub>2</sub> během sestupu. Je třeba rychle sestoupit; přirozený vzestup ppO<sub>2</sub> musí být rychlejší než spotřeba kyslíku.\n\nPoužití nastavené hodnoty pro sestup musí být povoleno v konfiguraci.\n\nPokud je povoleno, je nastavená hodnota sestupu automaticky aktivována při přepnutí z povrchového režimu do režimu CCR. Nelze ji aktivovat jiným způsobem. Nastavená hodnota klesání má proměnnou hodnotu. Počáteční nastavená hodnota udává hodnotu ppO<sub>2</sub> na povrchu. V hloubce se aktuální nastavená hodnota lineárně zvyšuje o 0,2 baru (20 kPa) na každých 10 m hloubky (tj. zvyšuje se o stejné absolutní hodnoty jako při potápění s otevřeným okruhem se vzduchem, pouze s jinou počáteční hodnotou).\n\nPo dosažení této hodnoty nebo po ukončení či výrazném zpomalení sestupu, nejpozději však po deseti minutách, se sestupová žádaná hodnota automaticky přepne na nízkou žádanou hodnotu.\n\nPři použití nastavené hodnoty sestupu musí uživatel průběžně kontrolovat, zda nedosáhl nebo nepřekročil maximální fyziologicky přípustnou hranici ppO<sub>2</sub>, a podle toho upravit rychlost sestupu nebo přijmout jiná opatření.\n\nNastavení sestupu lze znovu aktivovat klávesovou zkratkou nebo z nabídky Nastavení (pokud se nacházíme v p

2říslušné hloubce).\n\nPokud je v nabídce Setup / Setpoints / nastaveno On+Sfc, pak sestupový setpoint na hladině nikdy nevyprší.\n\n**<span style=„color:red“>UPOZORNĚNÍ: pokud je počáteční hodnota SP sestupu nižší než nastavená prahová hodnota pro alarm Low ppO<sub>2</sub>, pak dokud je SP sestupu aktivní, alarm se spustí pouze v případě, že dosáhne hodnoty o 0,05bar nižší, než je aktuální hodnota SP sestupu - to platí zejména v hloubkách menších než 6 m, kdy je SP sestupu nastaven na 0,2bar (na hladině) a výchozí alarm Low ppO<sub>2</sub> je 0,3bar.</span>**.\n\n**Omezení setpointu**\n\nKromě nastavené hodnoty je mezní hodnota žádané hodnoty definována okolním tlakem. Například v hloubce 3 m, kde je hydrostatický tlak 1,3 baru, může ppO<sub>2</sub> při použití čistého kyslíku dosáhnout maximálně 1,3 baru.\n\nProtože dosažení presice 100 % kyslíku ve smyčce není vždy praktické, je nastavená hodnota standardně nastavena na 90 % okolního tlaku. Tuto hodnotu lze přenastavit v rozmezí od 60 % do 96 %.\n\n**Nouzová kontrola ppO<sub>2</sub>**\n\nPokud nejsou všechny chemické senzory platné (chyba, vypnuto atd.), hloubka je < 6 m/20 stop a zdrojem ppO<sub>2</sub> jsou senzory O<sub>2</sub>, provádí se každých 6 s nouzové vstřikování O<sub>2</sub> + alarm.\n \nPřístroj předpokládá, že v hloubce nižší než 6 m je riziko hypoxie větší než riziko hyperoxie, a zabraňuje fatálním následkům nefunkčních nebo vyřazených senzorů.

Tuto možnost použijte, pokud se chcete po celý ponor potápět s nízkým SP nebo jednoduÅ¡e chcete zobrazit TTS s aktuální setpointem namísto vysokého SP.\n\n**Gas switch**\n\nTuto možnost vyberte, chcete-li nastavit minimální délku spínacího dorazu pro záchranný výstup s otevřeným okruhem. Při této zastávce se potápěč snaží využít vysoké ppO<sub>2</sub> a efektu kyslíkového okna při změně směsi. Hloubka zastávky se nastaví automaticky podle ppO<sub>2</sub> směsi. Při výstupu se používá ppO<sub>2</sub> 1,6. Při výstupu se používá ppO<sub>2</sub> 1,6. Pokud je zastávka hlubší než první dekompresní zastávka, vytvoří se samostatná zastávka, která je zahrnuta do plánu výstupu a spotřeby plynu. Pokud se hloubka nachází ve stupňové dekompresní zóně, nastavení určuje minimální délku zastávky. Číselná hodnota představuje délku v minutách. Pokud je zvolena nulová hodnota, zastávka se nezapočítává.\n\n**Deep stops**\n\nZde můžete zahrnout další hluboké zastávky, abyste omezili tiché bubliny. Postup výpočtu Richarda Pyla se používá ke snížení tlaku mezi začátkem výstupu a hloubkou první dekompresní zastávky na polovinu. V této variantě je nutné zvážit nastavení gradientních faktorů tak, aby nedoÅ¡lo k nasycení středních a pomalých tkání.\n\n**Upozornění: V dneÅ¡ní době se použití deep stops nedoporučuje!

Nechte vítr, aby odstranil nejjemnější prachové částice.\n\nPokud pracujete v interiéru, sypte sorbent do kazety z minimální výšky. Prach ze sorbentu je agresivní a může způsobit korozi. Proto nedoporučujeme pracovat se sorbentem například uvnitř automobilu.\n\nAbyste zabránili propadnutí sorbentu do centrální trubice, umístěte přes otvor kovové diskové víko kanystru nebo jej ucpěte jiným vhodným způsobem. Nasypte sorbent do kazety, dokud nebude přibližně z jedné třetiny plná. Poté kazetu opatrně zvedněte a nechte ji třikrát spadnout z výšky přibližně 1 cm (1/2\"). Tento postup opakujte, když je kazeta ze dvou třetin plná, a znovu, když je zcela plná. Kazeta je zcela plná, když sorbent dosáhne úrovně mezi min. a max. ryskami vyznačenými na středové trubici.\n\nPo naplnění umístěte kovový kotouč a přítlačnou desku s pružinou na horní část sorbentu. Poté sejměte přítlačnou desku a víko a zkontrolujte, zda je povrch sorbentu vyrovnaný a zda se nevytvořily žádné kanálky. Kovový kotouč a přítlačnou desku s pružinou opět umístěte na horní část sorbentu; přitlačte a zajistěte sestavu pojistným kroužkem. Pojistný kroužek musí zapadnout do drážky na přítlačné desce.\n\nNení-li kazeta dostatečně naplněna, zůstane mezi okrajem víka a okrajem kovové mřížky mezera menší než 6 mm nebo menší. V takovém případě přidejte sorbent a poté kazetu protřepejte a uzavřete podle výše popsaného postupu.\n\nPokud je kazeta přeplněna, zůstane mezi okrajem víka a okrajem kovové síťky mezera větší než 17 mm a nebude možné bez nadměrné síly vložit pojistný kroužek.

2řebytečný sorbent čistou lžičkou nebo jiným vhodným nástrojem. Protřepejte kazetu a opět zavřete víko.\n\nPřed vložením kazety do nádoby čističe zkontrolujte, zda je lapač vody suchý. Pokud tomu tak není, vyjměte lapač vody a vysušte jej ručníkem.\n\n**Po každé výměně absorbentu je třeba vynulovat časovač zásobníku Menu / Před ponořením / Reset času zásobníku**.\n\nStack time měří používání skruberu jednoduchým počítáním času stráveného v režimu ponoru. Můžete nastavit, zda se čas stack time počítá na hladině, nebo ne.\n\nPrach ze sorbentu poškozuje textilie, zejména polyamidové a bavlněné tkaniny. Proto po práci se scrubberem okamžitě vyperte ručník, na kterém byla umístěna kazeta, a veškeré oblečení, které bylo vystaveno působení sorpčního prachu.\n\nNepracujte se sorbentem v blízkosti nosných popruhů, lan nebo dokonce kovového horolezeckého či speleologického vybavení. V případě možného kontaktu se sorbentem je třeba lana a nosné popruhy okamžitě zlikvidovat, protože se může výrazně zhoršit jejich nosnost.\n\n**Stav sorbentu před ponořením**\n\nScrubber musí mít dostatečnou absorpční kapacitu pro plánovaný ponor.\n\nSorbent musí obsahovat určité množství vlhkosti, aby mohly probíhat chemické reakce, které umožňují odstraňování CO<sub>2</sub> z dýchací směsi. To znamená, že skruber nesmí být zcela suchý nebo zmrzlý.\n\nV mrazivém počasí uložte rebreather před ponorem do teplého prostoru.

Pokud jste takový kurz úspěšně neabsolvovali, přenechte míchání směsi kvalifikované osobě.\n\nPři manipulaci s kyslíkem dodržujte postupy a pravidla, se kterými jste byli seznámeni v kurzu trimixu a následně v kurzu CCR Liberty. Pokud jste takový kurz úspěšně neabsolvovali, s přístrojem CCR Liberty nemanipulujte.\n\n**3.2.5.1 Diluent**\n\nZvolte diluent, který je schopen z dýchací smyčky vyplavit směs s vysokým obsahem kyslíku. Připravte si ředidlo tak, aby byl parciální tlak kyslíku v největší hloubce vašeho plánovaného ponoru o 0,2 baru nižší než plánovaná nastavená hodnota. Parciální tlak dusíku by neměl překročit 4 bary (doporučuje se 3,2 baru).\nS ohledem na kompatibilitu s kyslíkem a čistotu pro kyslíkovou službu dílů pracujících s ředidlem nepřekračujte v ředidle koncentraci kyslíku 21 % (± 1 %). Minimální koncentrace kyslíku je 5 %.  \nKontaminace diluentu by neměla překročit limity dané normou EN12021:2014. Oddíl 6.2 při použití stlačeného vzduchu pro jednotku.\n\nUjistěte se, že ředicí prostředek byl naplněn kompresorem s řádně udržovanými filtry.   \n\nPlyn musí splňovat požadavky normy EN12021:2014.\nPřípadně můžete použít osobní filtr. Při použití kompresoru se spalovacím motorem zajistěte, aby se výfukové plyny z motoru nedostaly do sání kompresoru.  \n\nSměsi s vyšším obsahem helia představují více výhod z několika důvodů. Směs s nízkým obsahem O2 na hladině v malých hloubkách s nedostatečnou dýchatelností však výrazně zvyšuje rizika.  \n\nPo naplnění napište složení směsi permanentním fixem na štítek (kousek lepicí pásky) a připevněte jej na láhev.  \n\nSpotřeba ředidla závisí na profilu ponoru, četnosti a rozsahu změn hloubky. Kapacita ředidla není omezena časem, ale profilem ponoru. To je třeba brát v úvahu zejména při plánování ponorů v jeskyních. Diluent se spotřebovává především během sestupu. Během výstupu je teoretická spotřeba 

2nulová a jakákoli praktická spotřeba je způsobena především čištěním masky.\nNa základě praktických zkušeností je typická spotřeba ředidla při jednoduchém ponoru do hloubky 40 m přibližně 50 až 70 barů. Tato hodnota se obvykle nezvyšuje delším pobytem ve stejné hloubce.  \n\nVždy si ponechte dostatečnou bezpečnostní rezervu (alespoň 50 barů) pro případ neplánovaných situací. Pokud je tlak v lahvi s ředidlem nižší než 70 barů, neměl by být zahájen ani krátký ponor.  \n\nPodle norem, podle kterých je přístroj CCR Liberty certifikován a označen CE, se nepotápějte do hloubek větších než 40 m. Proto je přístroj CCR Liberty certifikován CE do 40 m.\n\n**Kyslík**\n\nPoužívejte kyslík určený k dýchání. Znečištění kyslíkem nesmí překročit limity dané normou EN 12021, oddíl 6.2 vpřípadě použití stlačeného vzduchu pro jednotku.\n\nDoporučujeme používat kyslík o čistotě nejméně 99,5 %.\n\nSpotřeba kyslíku pro výpočet doby trvání plynu je 1,78 l/min podle normy EN 14143:2014. Uvážíme-li počáteční tlak v lahvi 200 barů a konečný tlak 50 barů v lahvi, vystačí zásoba kyslíku na 253 minut. Při tomto výpočtu se neuvažuje kyslík obsažený v ředidle.\n\nTyto podmínky odpovídají vysoké fyzické námaze během ponoru. Pokud je potápěč během ponoru klidný, spotřeba se výrazně sníží a množství kyslíku i životnost sorbentu se prodlouží. Plán ponoru, který se spoléhá na to, že celý ponor bude probíhat s malou námahou, je nepřesný.\n\nKaždopádně na ponor postačí láhev s kyslíkem naplněná na 200 barů, což značně přesahuje dobu provozu sorbentu CO<sub>2</sub>.\n \nPokud je tlak v kyslíkové lahvi nižší než 70 barů, neměl by být zahájen ani krátký ponor.\n\nPodle platných technických norem je plnění kyslíku na provozní tlak vyšší než 200 barů zakázáno.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#359","type":"component","lock":false,"position":55},{"name":"Divider","data":{"color":"darkGray"},"id":"#360","type":"component","lock":false,"position":56},{"name":"SectionDivider","data":{"title":"3.2.6 Battery charging"},"id":"#586","type":"component","lock":false,"position":57},{"name":"TextBlock","data":{"text":"### <span id=\"3-.-2-.-6-Battery-charging\">**3.2.6 Nabíjení baterie**</span>\n\nPřed nabíjením baterií vyjměte propojky ze zásuvek.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#361","type":"component","lock":false,"position":58},{"name":"TextBlock","data":{"text":"Doporučujeme nabít baterie na plnou kapacitu týden nebo méně před potápěním.

Sejměte hlavu s připojenými sluchátky a HUD.\n8. Vyjměte čistič CO<sub>2</sub> z kazety a bezpečně jej zlikvidujte.\n9. Vyjměte nádobku s čističem z opěrné desky a odstraňte lapač vody.\n\nHlavu s ovládacími jednotkami uložte na čisté, chladné a suché místo.\n\n10. Připravte antiseptický roztok do vhodné nádoby, zbavené mechanických a chemických nečistot. K dezinfekci je vhodná například vana, vana na maltu nebo velká nádoba Tupperware.\n\nPro běžnou dezinfekci použijte 0,5% koncentrovaný antiseptický roztok Divesoft. Při práci s antiseptickým prostředkem postupujte podle návodu.\n\nOpláchněte čistou čerstvou vodou a do vany umístěte hadici, sifon, sestavu vlnité hadice s otevřeným DSV, dýchací vaky a filtr CO<sub>2</sub>. Manipulací se sestavou vlnité hadice a DSV vypusťte vzduch tak, aby antiseptický roztok vyplnil celý prostor (tato nezbytná dovednost se vyučuje v 

2kurzu CCR Liberty). Dýchací vaky zcela naplňte antiseptickým roztokem.\n\nPokud zaznamenáte růst plísní, je nutné provést důkladnou dezinfekci a vyčištění povrchu. Většinu povrchů lze otřít hadrem napuštěným antiseptikem. K čištění vnitřních povrchů vlnitých hadic použijte kartáč na lahve nebo trubky.\n\nPonechte díly v antiseptickém roztoku po dobu jedné hodiny. Po dokončení vyjměte díly a opláchněte je čistou čerstvou vodou, poté je nechte uschnout. Díly nesušte na přímém slunečním světle.\n\nPokud je vyžadována intenzivnější dezinfekce, použijte koncentrovanější roztok (maximálně 2 %) nebo nechte díly v antiseptickém roztoku delší dobu (maximálně čtyři hodiny).\n\nMísto dezinfekce Divesoft lze použít jiný antiseptický prostředek na bázi kvartérních amonných solí, který je kompatibilní s materiály, z nichž je vyroben CCR Liberty. Výrobce zařízení CCR Liberty nezaručuje kompatibilitu jiných antiseptických prostředků než dezinfekce Divesoft. V žádném případě nepoužívejte prostředky na bázi chlóru.\n\nZa normálních okolností není třeba dezinfikovat hlavu, ADV, ruční obtokové ventily a přetlakový ventil.\n\nPokud je nutná důkladnější dezinfekce, lze z hlavy vyjmout kyslíkové senzory a zbývající části omýt antiseptickým roztokem. ADV, ruční obtokové ventily a přetlakový ventil lze dezinfikovat ponořením do antiseptického roztoku.\n\nAntiseptický roztok je vysoce toxický pro vodní organismy.

Proto doporučujeme vyměnit senzory nejpozději do jednoho roku od jejich uvedení do provozu nebo max. 18 měsíců od data výroby.\n\nNicméně, i přes správné zacházení, mohou senzory, vykazovat odchylky nebo omezení i během jejich doporučené životnosti.

Je to jediný přesný a bezpečný způsob, jak odhalit vadný nebo omezený senzor.\n\nVyměněné snímače není nutné vyřazovat.

The trip was organized by the Liberty Divers Club and run by Dirty Dozen Expeditions and was specifically for divers using the Liberty CCR. I signed up for the trip even though I didn't have much experience in wreck diving. However, the idea of exploring the wrecks, particularly the B17 Bomber around the world, had always intrigued me in a mysterious way. I made up my mind to dive the best wrecks in the world.","content":"![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7607820f3a7bdda7c47c604b517414ef5aabad4b_dan-sun-in-bikini-atoll-with-ccr-liberty-family-02.jpg)\n\n**How I got started**\n\nI began my diving journey in 2017 after accepting an invitation from a colleague and quickly became passionate about it. I dived locally in Hong Kong every weekend and traveled overseas for diving almost every month. I was always looking for the best training and gear, and I was especially drawn to sidemount diving because it allowed for extended range and high individualization. As I progressed, I struggled with the weight and fit of multiple tanks. This led me to discover the Liberty sidemount CCR. I was drawn to it because of the user-friendly interface and DiveSoft’s education content. It helped ease my transition into the CCR world.\n\nI fell in love with my Liberty sidemount, and have been ever since. It is reliable and has never failed me during critical training dives or remote trips. Its redundancy helped me to complete a deco obligation without urgent bailout, giving me ample time underwater to solve problems.\n\nAfter three years of diving the CCR Liberty, I had accumulated about 230 dives, in a total of 280 hours. I felt ready to put it to good use.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/51a7349549e467f5de653c0c9845392e735a2738_dan-sun-in-bikini-atoll-with-ccr-liberty-family-03.jpg)\n\nAs a woman in the tech diving community, I initially felt self-conscious and faced many unsolicited pieces of advice and comments. However, with time, I gained confidence and began to appreciate the privileges and support I had in pursuing my passion for diving.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/b509d51b0890deb8b3918b20ce4eb91eb1948c42_dan-sun-in-bikini-atoll-with-ccr-liberty-family-04.jpg)\n\n**Getting ready for Bikini*

2*\n\nPreparing for the Bikini trip for me was a meticulous process, including completing a 60m trimix CCR course, advanced wreck diving training, and a 14-day diving trip to Chuuk as a warm-up. I spent time in Chuuk configuring my equipment to ensure optimal trim and buoyancy for navigating the wrecks in Bikini.\n\nThere was some banging around at the tight corner of the staircase in Chuuk, but the Liberty handled the roughness despite a few scratches and oil stains on the unit.\n\nPacking for a remote trip with the full setup gear was never easy. I managed to utilize the two free 23kg bags of United Airlines, with each suitcase carrying the Liberty and SeaCraft GO DPV. All regs and batteries went into the carry-on and backpacks.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/79de14e96cdd328be75c55e9eefcfd5051e3bb8a_dan-sun-in-bikini-atoll-with-ccr-liberty-family-05.jpg)\n\nYet I underestimated the logistics to Bikini, especially knowing I needed a visa for both Guam and the Marshall Islands as a Hong Kong passport holder. We needed to count stops with the \"Island Hopper\" and hoped our luggage arrived at the same spot.\n\nBut it was worth it when I landed in Kwajalein, the military base which led to Ebeye, a residential area. I learnt about the day-to-day life of a local Marshallese and enjoyed a beautiful stroll on the atoll.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/136b0ed8971f069994a9e341a3ea037e02cc1fa9_dan-sun-in-bikini-atoll-with-ccr-liberty-family-06.jpg)\n\n**Is Bikini worth it?**\n\nMany divers have asked me if diving in Bikini Atoll was worth it, considering the cost and logistical challenges. While it is indeed more expensive and less accessible than other diving destinations like Chuuk, the experience was absolutely worthwhile for me.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/bd29204f2d213933a365c1b87769502e78a4a8d6_dan-sun-in-bikini-atoll-with-ccr-liberty-family-07.jpg)\n\nBikini Atoll is like Chuuk 2.0, with amazing wildlife. It is shielded from currents and wakes, as Chuuk is, but it is better because it is also a sanctuary for juvenile sharks and rays, as well as many \"economically important species\" that have been hunted to extinction in many places.  \nThe weather was amazing, with bright sunlight during the day and the clearest sky to see the moon and stars at night. We went on the Bikini Atoll for an archeological visit - it was surreal as the time froze the moment the lone watchman had to abandon the location.\n\nDespite the smaller number of wrecks, the iconic sites in Bikini, such as the USS Saratoga, were incredibly well-preserved and held a vivid history that made the trip unforgettable. The dentist's, the sick bay and the dive locker live up to their fame.\n\nBehind every iconic wide-angle shot is a photographer squeezed into a tight corner, striving to capture the whole room along with a seemingly effortless diver.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7a139e47182c11b0f0b8063cea5f17d9c0e7ae78_dan-sun-in-bikini-atoll-with-ccr-liberty-family-08.jpg)\n\nAnother of my favorite wrecks is the IJN Nagato, which provides the most iconic studio shot. The illuminated double 16-inch guns at the bottom, the four propellers and two rudders on the top, make for an unforgettable Bikini Atoll postc

2ard shot.\n\nDiving alongside a diverse group of passionate wreck divers in a paradise-like location with rich history is truly exceptional.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/1bc0f257b032786198a1f504b7b6533c13013e6c_dan-sun-in-bikini-atoll-with-ccr-liberty-family-09.jpg)\n\n**So what's next for me?**\n\nI've checked the boxes of Chuuk and Bikini within a year. What's left? There are so many wrecks out there waiting for me - the Red Sea, Croatia, Malta, the Great Lakes, even the HMHS Britannic, and the list goes on.\n\nThis trip has energized and motivated me. It shows the possibilities of life and how rewarding it can be when we aim for something great, take calculated risks, and prepare with focus and intention.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/735de0fa204b5323ce63d323f039875b5e924656_dan-sun-in-bikini-atoll-with-ccr-liberty-family-10.jpg)\n\nI also want to share my passion and knowledge with others. After years of fun diving, I want to become an instructor and in the future, a tech instructor, so I can inspire more divers to pursue their passion and dreams.\n\nI'm already looking forward to the next Liberty Divers Club trip and another epic journey as a team. Will you join me?\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/120b3d0ff126c363d07b6b28ead75b42206605e3_dan-sun-in-bikini-atoll-with-ccr-liberty-family-12.jpg)\n\n**About the Author:  **\n\nDan Sun is a technical diver, sailor and titanium hardware seller based in Hong Kong.

2n\n**Note**: before setting the values for the first time, you can change the metric/imperial units in the User settings to the ones you want.  \n\n### Planner settings\nSelect the type of dive you will be shooting for CCR = Rebreather, OC = Open Circuit\n#### CCR settings\n**SP Descent** - PO2 setpoint to be used during descent in the planner. Note that this is not the variable descent setpoint known from the CCR Liberty setup, but a fixed setpoint for the entire descent until maximum depth is reached.  \n**SP bottom** - setpoint used in the deep part of the dive  \n**SP deco** - setpoint used for ascent. It starts at the exit start point.\n#### OC settings and common settings\nThe following items are common to both CCR and OC.  \n\n**SAC stress** - Surface consumption on the open circuit for the duration of the emergency. Consumption is recalculated for ambient pressure. Set high consumption for realistic planning when a critical underwater problem is being addressed at the worst possible moment. In the case of a CO2 hit, consumption can rise well over 75 l/min. The SAC stress value is calculated into the plan for the time specified in the Stress time item.  \n\n**SAC Deco** - Surface consumption on open circuit after Stress time.\n\n**Stress time** - time during which high SAC stress consumption is calculated. Consider the set length for realistic bailout gas consumption planning.\n\n**Problem solving time** - the time that is added to the time at the bottom in the event of a bailout. This includes time for problem solving such as switching the gas, deploying the buoy, alerting the team, bailing out, etc. \n\n**Loop volume** - the volume of the breathing loop for calculating diluent consumption. For realistic diluent consumption planning, we recommend at least doubling the actual value to account for depth changes while on the bottom and minor gas leaks.\n\n**Metabolic consumption** - physiological oxygen consumption. When adjusting, take into account possible emergency situations, dive conditions and minor gas leaks.\n\n**Ascent rate zones**: set the ascent rates in three different depth ascent zones. Define the depth zones to the right of the imaginary ascent profile shown by the diagonal line. The ascent velocities in each zone are to the left of the imaginary profile.   \nClick on a specific entry and change it in the field below.\n\n**Descent rate**: set the descent rate. \n\n**GF Low/High**: gradient factors for modifying the ascent curve of the standard ascent. GF Low modifies the depth of the first stop (a lower value generates a deeper first stop). GF High determines the degree of tissue saturation at the time of emergence compared to the Buhlmann algorithm. Simplistically, the lower the number, the more conservative. The recommended setting is 40/75.\n\n**BO GF Low/High**: setting gradient factors for bailout ascent. It is assumed that when switching to bailout the diver wants to leave the water faster. For this reason it is possible to set a slightly more aggressive GF.\n\n**END**: Setting the equivalent narcotic depth. Generates a warning if the END is exceeded when using a breathing mixture at a given depth.

Nastavujte vysokou spotřebu pro realistické plánování ve chvíli, kdy je řešen zásadní problém pod vodou v nejhorším možném okamžiku. V případě CO2 hitu může spotřeba vyrůst i hodně přes 75 l/min. Hodnota SAC stress je počítána do plánu po dobu stanovenou v položce Stress time.  \n**SAC Deco** – Povrchová spotřeba na otevřeném okruhu po uplynutí Stress time.    \n**Stress time** -  čas během kterého je počítána vysoká spotřeba SAC stress. Zvažte nastavenou délku pro realistické plánování bailoutové spotřeby plynu.  \n**Problem solving time** – čas, který je přičten k času na dně v případě přechodu na bailout. Je započítán čas pro řešení problému jako je přepnutí plynu, vystřelení bóje, upozornění týmu, vyproštění se apod.   \n**Loop volume** – objem dýchací smyčky pro výpočet spotřeby diluentu. Pro realistické plánování spotřeby diluentu doporučujeme skutečnou hodnotu přinejmenším zdvojnásobit, aby byly brány v úvahu změny hloubky během pobytu na dně a drobné úniky plynu.\nMetabolic consumption – fyziologická spotřeba kyslíku. Při nastavení berte v úvahu případnou nouzovou situaci, podmínky ponoru a drobné úniky plynu.  \n**Ascent rate zones**: nastavte výstupové rychlosti ve třech různých hloubkových zónách výstupu. Hloubkové zóny definujte vpravo od pomyslného profilu výstupu znázorněného šikmou úsečkou. Rychlosti výst  upu v jednotlivých zónách jsou nalevo od pomyslného profilu. \nKlepněte na konkrétní údaj a změňte ho v poli níže.  \n**Descent rate**: nastavení rychlosti sestupu.   \n**GF Low / High**: gradientní faktory pro modifikaci výstupové křivky standardního výstupu. GF low modifikuje hloubku první zastávky (nižší hodnota generuje hlubší první zastávku). GF High určuje míru nasycení tkání v okamžiku vynoření ve srovnání s Buhlmannovým algoritmem. Zjednodušeně lze říci, že čím nižší číslo, tím konzervativnější. Doporučené nastavení je 40/75.  \n**BO GF Low / High**: nastavení gradientních faktorů pro bailout výstup. Předokládá se, že při přechodu na bailout potápěč chce rychleji opustit vodu. Z toho důvodu je možné nastavit o něco agresivnější GF.  \n**END**: Nastavení ekvivalentní narkotické hloubky. Generuje varování při překročení END při použití dýchací směsi v dané hloubce. Optimální nastavení END je 28 – 30 m.  \n**Oxygen is Narcotic**: Určuje, zda je při výpočtu END započítán narkotický potenciál kyslíku.  \n**Deco algorithm**: Vyberte ze dvou dekompresních Algoritmů. ZHL16B je původně určen pro dekompresní tabulky. ZHL16C je původně určen pro potápěčské počítače a je mírně konzervativnější.   \n**Salinity:** Určete v jaké vodě se budete potápět - slaná, sladká nebo definovaná salinita EN 13319 odpovídající přibližně brakické vodě.  \n**Last stop depth**: Určete jaká bude hloubka poslední dekompresní zastávky.  \n**Deco step**: Určete po jak velkých krocích budou plánovány vaše dekompresní zastávky   \n**End pressure**: Bezpečnostní rezerva tlaku v lahvi (kolik musí v lahvi zůstat)\n","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#196","type":"component","lock":false,"position":35},{"name":"TextBlock","data":{"text":"## Cylinders\nNastavení potápěčských lahví a směsí.

The nice thing was that I took the PADI OWD course in Egypt and instead of pool dives, the \"controlled\" conditions were in a beautiful sandy lagoon surrounded by coral. So logically, the AOWD course followed a year later in a similar location.","content":"For the next few years I did s

2ome occasional diving in summer resorts and warm seas. A shift came when I headed to the Austrian Lakes with a group of divers called Kapr Divers. Here I saw something I had only read about up until then. The divers had dry suits, lots of gear and were diving unimaginably deep. When the instructor of Kapr Diver - Petr Slezak asked me if I wanted to learn more about technical diving, there was no waiting!\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7da6803ca587b4d1a1e1b699a6ebf65923d7c9e3_martin-mako-janecek-my-diving-journey-to-ccr-liberty-1.jpg)\nPhoto: René Valvoda, recreational diving at Easter Island\n\nHowever, the very beginning of technical diving was not easy for me. I was motivated by the feeling that technical diving with its principles and doubling of equipment is in principle safer and that it is actually rather a coincidence that I  even survived the years of recreational diving 😊.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c4706bd1adcfeaef11dbdf84a52a62b88cf5a948_martin-mako-janecek-my-diving-journey-to-ccr-liberty-2.JPG)\nPhoto: Kapr Divers, exploration of the Judit Bridge foundations using open-circuit (OC)\n\nMy status as a technical diver opened the way to interesting places around the world and at home. I was never particularly good at history, but adding information and historical context about sunken ships or flooded buildings made the dives themselves a more comprehensive experience.\n\nAnother logical consideration to get to more wrecks and interesting places was the inclusion of Helium-added mixtures.\n\nThe combination of the cost of deep diving with Trimix, and the limited dive time due to the amount of mixtures in the bottles led to logical considerations on how to solve these handicaps. Moreover, despite my best efforts, my surface equivalent consumption (SAC) was above that of my dive partners and I was always the one turning the dive and thus planning it. In 2015, a \"meeting\" was held at Kapr Divers which resulted in the consideration of purchasing rebreathers, i.e. closed circuit breathing apparatus. This would solve the cost of diving with Trimix and partly limit the number of dives with a lot of mixtures. Another advantage considered was the quiet operation underwater and therefore the possibility of better fish observation. The positive impact of the still ideal mix in the rebreathers on overall post-dive fatigue and decompression progress was also an assumed plus.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5a711a60d1e79a052da5ff0e8a48df7b3e2d4242_martin-mako-janecek-my-diving-journey-to-ccr-liberty-3.JPG)\nPhoto: Kapr Divers, team dive with open-circuit to 100m at Attersee\n\nIn the end, the three of us decided: this was  the way to go! One of the reasons was that we just wanted to move up to the next level. The very desire and logical arguments described above were supplemented by the calculation of the return on the considerable sum invested in the rebreather. The result was shocking, and the payback came  after only a few dozen dives with the Trimix, which for us represented a period of about one year with our style of diving.\n\nIt was kind of just a formality  to confirm the choice of which particular device to use . Our consideration led us to the CCR Liberty. Moreover, this instrument could newly boast CE certification, which made it unique at the time. However, the Liberty's uniqueness is much broader than that, and quite crucial in terms of safety and practicality of diving. The device is very well ergonomically designed and all key components are duplicated.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/67e867af57f442170c08821a074aef1cf3a6f134_martin-mako-janecek-my-diving-journey-to-ccr-liberty-4.JPG)\nPhoto: Kapr Divers, diving at Orlík Dam with CCR Liberty\n\nBuying a CCR Liberty and taking the CCR Liberty diver course completely changed my diving options. I started using the Trimix for dives that I had previously done with air. The cost of the dive was completely negligible but  the dimension of the dive with the TMX changed significantly compared to air. Gradually I had the opportunity to visit many other great wrecks and dive sites. Flooded caves were suddenly divable much further from the entrance. But there were also some negative observations. While I didn't have to constantly refill my breathing cylinders during the dive, I again had to keep a number of cylinders in reserve for use as backups to the primary CCR Liberty unit. But this fact was amply redeemed by the wonderful dives that would have been almost impossible using OC technology. Worthy of mention is the breathtaking neck of the German submarine U 455 at 120 meters off Genoa, Italy, the wreck of the tanker Haven there, or the repeated nearly four-hour dives in the iconic French Ressel Cave.  I was also able to spend much more time at the now famous B-17 wreck.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/54f03ee820dad216e155ef49146df508cb6167c1_martin-mako-janecek-my-diving-journey-to-ccr-liberty-5.jpg)\nPhoto: Marian Chachalák, dive with back-mounted CCR Liberty on the B-17 bomber wreck – Vis, Croatia\n\nOver time, I have added the option of diving with the CCR Liberty in the \"back mount\" configuration by purchasing a conversion kit. This allowed me to reduce the weight of the transported gear and increase the agility during dives. This option has been especially useful for dives in narrow caves and wreck penetrations. Despite my initial opinion that this is not a configuration suitable for Trimix diving due to the backup and drysuit inflation solution, I am now enthusiastic about Trimix dives with the need for a two-bottle backup. Especially when diving at Truk Lagoon I appreciated this. The overall weight of the unit for airplane transport allowed the use of a single piece of luggage, and the two backup cylinders provided ample space for dives to depths of around 60 meters. Most air dives were also enjoyable and I appreciated the use of the CCR in this area.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/080fc3234f29ad9e71bf3ffebdb18abb3f6f5502_martin-mako-janecek-my-diving-journey-to-ccr-liberty-6.jpg)\nPhoto: Marian Chachalák, dive with side-mounted CCR Liberty in the flooded Kobanya mine, Budapest\n\nThe last CCR course I took, on the other hand, took me a very big step forward. Under the vision of interesting expeditions, I decided to replace a number of backup bottles with a second \"backup\" CCR Liberty device. The concept is relatively simple, but it has taken me that much further. The primary CCR Liberty dive unit is backed up by a second CCR Liberty unit in a Side Mount configuration. A single bottle of OC backup is already sufficient for this setup in case of a complicated transition between instruments. Overall, this setup of two CCR Liberty and one bottle is sufficient for any depth while maintaining CO2 absorber time in an appropriate planning strategy. The great advantage of this configuration is that Divesoft, as the only manufacturer, has software that provides the decompression profile calculation on both units identically and without the need for an additional computer allows a 

2safe transition from one unit to the other at any stage of the dive.   With this equipment, I have participated in several diving expeditions to identify previously undived wrecks. Apart from discoveries in the Atlantic Ocean around the Faroe Islands or Orkney.  I had the opportunity to be a member of the expedition that successfully identified the WWI German minelaying submarine UC - 55 in the area of the Scottish Shetland Islands. I consider this dive to a depth of 105 metres in the harsh conditions of the North Sea to be iconic and unforgettable.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/1cd3de4f9a6162b2afb3f6aafae4bb4a39783ebf_martin-mako-janecek-my-diving-journey-to-ccr-liberty-7.JPG)\nPhoto: Tomáš Zloch, dive with back-mounted and bailout side-mounted CCR Liberty, wreck of Olsana, Faroe Islands\n\nIn my diving practice I have encountered many divers using different CCR instruments or different configurations of CCR Liberty. I have participated in many emotional debates on the topic of which instrument or configuration is best. Certainly the key takeaway is that something a little different suits everyone, and as long as you are used to your apparatus and configuration, diving responsibly and safely, you are not wrong. For me, Divesoft is the clear choice. Beyond the instrument concept and the constant evolution, I have to appreciate the support I get to enjoy. At the same time, I have also been involved in several small improvements based on my own experience and this is another important factor for me if the manufacturer is inspired by the users.\n\nI wish everyone a wonderful and safe diving in any mode, conditions and equipment\n\n\n\n**About the Author:  **\n\nMartin Mako Janeček  \n[facebook.com/mako.janecek](https://www.facebook.com/mako.janecek)","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":1618178,"hash":"ea5e0de412c60d75f065c39c0a5de50a00ba94ed","id":"cm1yxhmgn82lm0874n5xbb6w1","filename":"martin-mako-janecek-my-diving-journey-to-ccr-liberty-0.jpg","category":"divesoft/","type":"image"},"publishDate":""},"id":"#2","type":"component","lock":false,"position":1},{"name":"BlogArticle","data":{"title":"Moje potápěčská cesta k CCR Liberty ","perex":"Moje první potápěčské zkuÅ¡enosti přiÅ¡li během dovolené, kdy jsem podlehl vábení animátora, který lákal na vyzkouÅ¡ení potápěčského přístroje v bazénu. Příjemné bylo, že jsem PADI OWD kurz absolvoval v Egyptě a místo bazénových ponorů se “kontrolované” podmínky nacházely v krásné písečné laguně obklopené korály. A tedy logicky o rok později následoval AOWD kurz na podobném místě.","content":"\nDalších několik let jsem se občasně věnoval potápění v letních letoviscích a teplých mořích. Posun nastal, když jsem zamířil k Rakouským jezerům se skupinou potápěčů Kapr Divers. Zde jsem viděl něco, o čem jsem do té doby jen četl. Potápěči měli suché obleky, velké množství výstroje a potápěli se nepředstavitelně hluboko. Když se mě instruktor Kapr Diver - Petr Slezák zeptal, zdali se nechci o technickém potápění dozvědět něco víc, nebylo na co čekat!  \n\nÚplné začátky technického potápění nebyly vÅ¡ak pro mě jednoduché. Motivací pro mě byl pocit, že technické potápění svými principy a zdvojením výstroje je v zásadě bezpečnější a že je vlastně spíš náhoda, že jsem roky rekreačního potápění vlastně přežil 😊.  \n\nStatus technického potápěče mi otevřel cestu na zajímavá světová i domácí místa. Nikdy mě dějepis nijak zvlášť neÅ¡el, ale doplnění si informací a historických souvislostí o potopených lodích, či zatopených budovách mě samotné ponory doplnilo na komplexnější zážitek.  \n\nDalší logickou úvahou, jak se dostat k dalším vrakům a zajímavým místům bylo zařazení směsí doplněných o Helium.  \n\nSpojení cenové nákladnosti hloubkového potápění s Trimixem a omezená doba ponorů daná množstvím směsí v lahvích vedla k logickým úvahám, jak tyto handicapy vyřeÅ¡it. Navíc i přes veÅ¡kerou snahu se moje ekvivalentní hladinová spotřeba (SAC) pohybovala nad spotřebou parťáků a byl jsem vždy tím, kdo ponor otáčel, a tím také i plánoval. V roce 2015 proběhla v Kapr Divers „porada“ jejímž výsledkem byla úvaha o pořízení rebreatrů, tedy přístrojů s uzavřeným dýchacím okruhem. To by mi vyřeÅ¡ilo cenovou nákladnost potápění s Trimixem a částečně i limitaci ponorů množstvím směsí. Další zvažovanou výhodou byl tichý provoz pod vodou a tedy možnost lépe pozorovat ryby. Předpokládaným kladem byl také pozitivní dopad stále ideální směsi v rebreatherů na celkovou únavu po ponoru a průběh dekomprese.  \n\nNakonec jsme se tři rozhodli: touto cesto půjdeme! Jeden z důvodů bylo i to, že jsme prostě chtěli postoupit na další stupínek. Samotnou touhu a logické argumenty popsané výše jsme doplnili i o výpočet návratnosti nemalé částky do pořízení rebreathru. Výsledek byl až Å¡okující a nÃ

2¡vratnost vycházela už po několika desítkách ponorů s Trimixem, což pro nás představovalo období okolo jednoho roku při naÅ¡em stylu potápění.  \n\nTak trochu jen formálním krokem bylo potvrzení výběru, jaký konkrétní přístroj zvolit. NaÅ¡e úvaha nás vedla k CCR Liberty. Navíc tento přístroj se mohl nově pyÅ¡nit CE certifikací, což ho v té době činilo unikátní. Unikátnost Liberty je ale mnohem Å¡irší a z pohledu bezpečnosti a praktičnosti potápění zcela zásadní. Přístroj je velmi dobře ergonomicky navržen a vÅ¡echny klíčové komponenty jsou zdvojeny.  \n\nKoupě CCR Liberty a absolvovaní kurzu CCR Liberty diver úplně změnilo moje potápěčské možnosti. Trimix jsem začal využívat i na ponory, které jsem dříve realizoval se vzduchem. Cena ponoru byla zcela zanedbatelná a rozměr ponoru s TMX se oproti vzduchu výrazně změnil. Postupně jsem měl možnost navÅ¡tívit řadu dalších skvělých vraků a potápěčských míst. Zatopené jeskyně se najednou daly potápět mnohem dál od vstupu. Objevily se ale i negativní poznatky. Sice jsem nemusel neustále plnit lahve pro dýchání během ponoru, ale zase jsem musel mít v zásobě řadu lahví pro využití jako zálohy primární jednotky CCR Liberty. Ale tento fakt byl bohatě vykoupen nádhernými ponory, které by s využitím OC technologie nebyly téměř možné. Za zmínku stojí úchvatný vratk německé ponorky U 455 ve 120 metrech u italského Janova, vrak tankeru Haven tamtéž, či opakované téměř čtyřhodinové ponory v ikonické francouzské jeskyni Ressel.  Také u již známého vraku letadla B-17 jsem mohl trávit mnohem delší dobu.  \n\nV průběhu času jsem doplnil možnost potápění s CCR Liberty v konfiguraci přístroje „na zádech“ o možnost varianty Side Mount a to dokoupením konversion kitu. Dovolilo mi to snížit váhu transportované výstroje a zvýšit obratnost při ponorech. Tato varianta se mi osvědčila především pro ponory v úzkých jeskyních a penetracích do vraků. Přes původní názor, že se nejedná o konfiguraci vhodnou pro Trimixové potápění z důvodu řeÅ¡ení zálohy a napouÅ¡tění suchého obleku jsem nyní nadÅ¡ený i pro Trimixové ponory s nutností zálohy do dvou lahví. Především při potápění na Truk Lagoon jsem toto ocenil. Celková váha přístroje pro dopravu letadlem dovolovala využití jediného zavazadla a dvě záložní lahve poskytovali dostatečný prostor pro ponory do hloubek okolo 60 metrů. VětÅ¡ina vzduchových ponorů byla také příjemná a využití CCR jsem v této oblasti velmi ocenil.  \n\nPoslední CCR kurz, který 

2jsem absolvoval mě naopak posunul o hodně velký krok vpřed. Pod vidinou zajímavých expedic jsem se rozhodl nahradit množství záložních lahví druhým „záložním“ CCR Liberty přístrojem. Koncept je poměrně jednoduchý, ale o to dál mě posunul. Primárný potápěčský přístroj CCR Liberty je zálohován druhým přístrojem CCR Liberty v konfiguraci Side Mount. K této sestavě již dostačuje jediná lahev OC zálohy pro případ komplikovaného přechodu mezi přístroji. Celkově tato sestava dvou CCR Liberty a jedné lahve je dostatečná pro jakékoliv hloubky při dodržení času pohlcovače CO2 v odpovídající strategii plánování. Skvělou výhodou této konfigurace je, že Divesoft, jako jediný výrobce má software, který zajiÅ¡Å¥uje výpočet dekompresního profilu na obou jednotkách totožně a bez nutnosti dalšího počítače umožňuje bezpečný přechod z jedná jedné jednotky na druhou v jakoukoliv fázi ponoru.   S tímto vybavením jsem se zúčastnil několika potápěčských expedic, které měli za cíl identifikovat do té doby nepotápěné vraky. Mimo objevy v Atlanstkém ocenu v okolí Faerských ostrovů, či Orknejí.  Jsem měl možnost být členem expedice, která úspěšně identifikovala německou minonosnou ponorku UC – 55 z první světové války v oblasti skotských Shetlandských ostrovů. Tento ponor do hloubky 105 metrů v nelehkých podmínkách Severního moře považuji za ikonický a nezapomenutelný.  \n\nV mé potápěčské praxi jsem se setkal s řadou potápěčů využívajících různé CCR přístroje, či různé konfigurace CCR Liberty. Účastnil jsem se řady emotivních debat na téma, který přístroj, či konfigurace je nejlepší. Rozhodně klíčový poznatek je, že každému vyhovuje trochu něco jiného a pokud je zvyklý na svůj přístroj a konfiguraci, potápí odpovědně a bezpečně, není to Å¡patně. Za mě je Divesoft jasná volba.

Our testing process is so meticulous, it would make NASA engineers proud.","content":"**The Brain of the Beast**\n\nJust like the human brain has two hemispheres, our CCR Liberty features dual control units (CUs). But before these electronic \"brains\" are installed, we put them through rigorous testing that would make your smartphone's quality control look like child's play.\n\nWe connect each control unit to our [specialized testing equipment](https://www.divesoft.com/en/blog/how-do-we-test-each-ccr-liberty) that checks:  \n• Bluetooth functionality  \n• Solenoid communication  \n• Sensor interfaces  \n• Power systems  \n• Handset communication  \n• Display functionality  \n• Firmware operations  \n\nThe units must perfectly measure oxygen, pressure, and helium levels using our calibration devices that simulate real-world conditions. It's like having a flight simulator, but for your life support system.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7b18a3da1663f9947de18aebb8c3ea115fc1be31_divesoft-photo-194.jpg)\n\n**The Oxygen Dance**  \n\nThe oxygen solenoids - crucial components that regulate your breathing mixture - undergo their own baptism. We pressure-test and submerge them in distilled water to ensure zero leakage. We scrutinize each solenoid for proper dosing, like a precision medical instrument.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/8d3588ee30125e8e045a51d2ea96de43d6f9c2af_divesoft-photo-090.jpg)\n\n**Pressure Testing: Going to the Extremes**  \n\nThink 340 meters underwater sounds deep? That's exactly what we test our units for. We subject the head unit to 3.5 MPa of pressure - equivalent to the crushing depths where only the bravest divers venture. Any structural weakness shows up at just 1 MPa, ensuring nothing slips through the cracks.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/12804b3edf597ecf844c5b58a6197f1b1430a0eb_divesoft-photo-196.jpg)\n\n**The Supporting Cast**  \n\nWe put our handsets - your underwater control panels - through a two-stage trial:  \n1. First pressure test without electronics  \n2. Final pressure test at a staggering 30 MPa with all components installed\n\nWe subject the Head-Up Display and Buddy Display to similar scrutiny, while we test the Manual Addition Valves (MAV), Automatic Diluent Valve (ADV), Dive Surface Valve (DSV), and Bailout Valve (BOV) both individually and as part of the complete breathing loop.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/88b8522ea06e26efa2a63465414cb9cfad1ec164_divesoft-photo-201.jpg)\n\n**The Final Symphony**  \n\nOur grand finale involves:  \n• Complete assembly  \n• Visual inspection following our detailed manuals  \n• Sensor calibration  \n• System checks  \n• Component serial number registration  \n• Pre-dive verification  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/0013c5cd71616f2464c93a32f56f116b77d92833_divesoft-photo-200.jpg)\n\n**Documentation: Nothing Left to Chance**  \n\nWe record every single step in a 17-page assembly journal unique to each unit.

This is the reason the Divesoft Lab was created. We are doing our best to ensure the equipment you dive with is thoroughly tested, understood, and the way we make it makes sense and is backed up by real experimental data.","content":"The crown jewel of the Divesoft Lab is Big Bertha, a custom-designed pressure chamber capable of simulating dives to depths of 300 meters. Big Bertha is much more than a simple pressure chamber; it mimics real-world underwater conditions with remarkable accuracy. Every diver has experienced first-hand, the water temperature can have a large impact on your body, we are making sure that the impact it has on your kit is minimal. Variable water temperatures ranging from a near-freezing 1°C to a scorching 60°C allow for [testing in most conceivable environments](https://www.divesoft.com/en/blog/how-do-we-test-each-ccr-liberty).  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7424642264f4a5f1c26f162e55f260030cc32dae_divesoft-lab-01.jpg)\n\nWhat sets Big Bertha apart is its high fidelity simulated respiration system. This system replicates a diver’s breathing cycle, including body-temperature warming and moisture addition to the gas, oxygen consumption, and CO₂ production. Paired with an array of sensors monitoring temperature, pressure, CO₂ levels, and other critical variables, Big Bertha provides an unparalleled evaluation of equipment performance under real-world diving conditions. We use this data to further optimize our equipment’s performance.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/3e13d7a44ad11b8bff661ab010da9295f324bf01_divesoft-lab-02.jpg)\n\nBeyond pressure testing, the lab houses a hydrostatic imbalance testing system. This setup evaluates how water pressure interacts with a diver's breathing apparatus during movement when they assume different positions underwater. The measurements done here are focused on preventing lung damage from hydrostatic imbalances—a potential risk if pressure differences between the diver’s lungs and their rebreather's breathing loop are not within certain levels.  \n\nAnother standout feature of the Divesoft Laboratory is its dedicated setup for analyzing scrubber performance. Scrubbers, which remove CO₂ from the breathing loop in rebreathers, are a critical component of devices like the CCR Liberty. The lab’s equipment allows us to evaluate scrubber depletion, identify potential breakthrough points, and optimize overall performance.  \n\nMoreover, a smaller automated pressure chamber tests the reliability of oxygen sensors under high partial pressures of oxygen. These tests simulate extreme diving scenarios to ensure that the sensors remain accurate and functional in the most demanding conditions.  \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/dd08b3c6739c889d337f2cc72cb6efd9183025c5_divesoft-lab-03.jpg)\n\nThe CCR Liberty rebreather is a great example of how these testing methods translate into superior product performance. This rebreather features dual control units for redundancy, advanced oxygen monitoring, and customizable dive interfaces. Its solenoids and sensors undergo meticulous pressure testing, ensuring reliability even at crushing depths. At Divesoft, every aspect of product development is a blend of precision engineering and an unyielding commitment to diver safety. From Big Bertha’s high-pressure simulations to hydrostatic imbalance testing, the company goes to extraordinary lengths to ensure its products perform flawlessly. Whether exploring a shipwreck, mapping underwater caves, or setting records in technical diving, divers can [trust that their Divesoft gear](https://www.divesoft.com/en/blog/would-you-trust-your-life-to-a-machine) has been tested far beyond the limits they will face.","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":1228119,"hash":"61b8c27499c83e555a14589c9a8ce6f71ce04191","id":"cm4jzozok17db0850uhqy02ye","filename":"divesoft-lab-00.jpg","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

Other scenarios to consider may involve the egress of the victim in difficult surface conditions, but a fair amount of common sense can dictate the best course of action based on what we’ve learned already from manuals.\nIn-water diver safety and rescues have been my focussed goal for many years as an educator, experimenting with multiple concepts, not just for single cylinder divers, but also for twin cylinder Backmount or Sidemount divers, multiple stage/deco cylinder or rebreather divers.\nI would prefer to call it advanced rescue diving techniques, to be an addendum, rather than to replace existing skillsets.\nLet’s assume we have a victim lying on the sea bed, or a wreck or a cave, we wouldn’t want to create another diving incident, by having two casualties, so please make sure you receive the right rescue training using correct diving techniques.  One of the most important skills required for this, is to be able to hover.  This is the balance of neutral buoyancy, without kicking or sculling to maintain position with very little effort.  This is one of the fundamental diving techniques associated with any kind of scuba diving.  Without this, a diver’s brain is less able to deal with anything extra than complex motor skills, determined to keep the body in position within the water column.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/a5c48020678970b7c091c106197a33d754de6fde_garry-dallas-rescue-techniques-02.jpg)\n\nAs with any rescue situation, it is paramount to asses the situation, rather than jumping straight in.   What does that involve?  Well, on open circuit it’s easy to tell if the victim is breathing or not, because there would be bubbles present escaping from the victim’s regulator heading to the surface.   On CCR you have to know what to look for, that would be a rhythmic expanding and contracting movement of the counterlung indicating a tidal volume, which may be quite small when the victim is unconscious.   Also it’s worth noting that if the victim is not in e-CCR mode or using a constant flow unit, the victim is actually metabolising the oxygen in the loop, which may lead to hypoxia and asphyxiation if left for too long.   So it’s vital to know how to add oxygen to the loop in any case.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/23a7a07ad1d1dbe1b57d98d5d77618a8c03b8077_garry-dallas-rescue-techniques-03.jpg)\n\nIn an i

2deal world, buddy checks between each member of team should be done to be more aware of what type of unit they are diving and discuss and/or confirm safety protocols, whilst they go about their business before the dive.   We all know too well, that the complacency is to our own detriment. \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/262eed9910183827c29cd96dc8f4f6862293f148_garry-dallas-rescue-techniques-04.jpg)\n\nIt must be said that ‘gag straps’ here in a rescue scenario, are a very advantageous piece of diving safety equipment. Yes, they may look a bit odd, but your family would be more happy if you gave yourself every chance to come home safely after every dive.  There are always discussions for and against gag straps, but as with every single piece of equipment in diving, there is a gradient percentage of pros and the same to oppose.  When the pros outweigh the cons, then it’s an overall plus!  We can all sometimes take for granted our abilities as competent technical divers, but in the end we can’t breathe water, yet. \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/9e534538f32c34cd72b67ea0deddbe03a8128f11_garry-dallas-rescue-techniques-05.jpg)\n\nGoing back to the observations, it’s about learning as much as possible quickly, before engaging in any rescue attempt.  Establishing the victim is unconscious but breathing, light signalling in front of the victim, waving a hand across the mask, gentle/firm squeezes to the arm or hand, being careful not to jolt the divers position.  It’s clear then they’re unconscious.  Now equipment checks… cylinder valves open, contents gauges check and handset/s check for PO2.  Now where is that O2 MAV… ?  One of the many clever ideas made by Divesoft, was to put the MAVs right next to the mouth, it’s such an accessible place not just for the diver but also for the potential rescuer.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/e7de66ab0dfe18ab4c935e92905f577e5f5b2dc3_garry-dallas-rescue-techniques-06.jpg)\n\nSo let’s discuss the rescuer… the rescue attempt could be done in either warm wetsuit, or cold drysuit environments.  Clearly fixed buoyancy can lend itself here to the victim, simply because a diver could be in trim as a result of that perfect physiology and body fat index with a neoprene covering and nicely trimmed out unit.  Otherwise, air space in the drysuit, could be more tricky to deal with alongside the art of negotiating how much air to add/vent from the wing, as well as the counterlung during ascent.  So here is where the rescuer takes over the entire control of the buoyancy of the combined package of the victim and rescuer.  The rescuer knows exactly where their own buoyancy inflators are, whilst very used to using them and completely accessible to them.  \nThere were generically idillic reasons for giving the buoyancy to the victim, basically in case the rescuer lost grip of the victim, the victim would ascend to the surface. In this case, the possibility the victim may not have sufficient gas for buoyancy to get them off the deck, so the wing is kept empty, since they’re ‘attached’ anyway.\nIn this technique the victim could be ‘attached’ to the rescuer via a large double-ender, connected from the rescuer’s front crotch D-ring, attaching to the victim’s rear crotch D-ring or rear metal frame of the unit.  Both rescuer above and victim underneath are almost sandwiched together facing the same direction, with plenty of room for the rescuer to navigate their hand/arm between them to access the rescuer’s inflators. \n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/4e92cab179153f06829b4bf9d3745860fe330e47_garry-dallas-rescue-techniques-07.jpg)\n\nMost importantly, the rescuer has one hand available to hold the loop firmly in place in the victims mouth, which can be interchanged between left or right hand. Whilst the other hand can be placed on the victims shoulder to steady the positional trim and control both pitch and roll, which in turn vents air from the victim’s drysuit and helps their feet up as and when needed.  All this while the rescuer keeps in their usual comfortable trim.  It would be like picking up any weight while attaching it to your harness D-ring, essentially turning your harness into an effective piece of rescue scuba gear.\nWhilst ascending in trim, venting off excess gas from the rescuer’s drysuit and/or wing, while doing the same for the victim’s drysuit.\nThe expanding gas from the victim’s loop can be vented in a few ways, either letting it vent from the mouth or manually pulling the dump valve if it’s accessible. The PO2 must monitored and maintained, easily done thanks to Divesoft’s MAV positions.\nControl is the key element here, buoyancy and PO2 control. If the unit’s on auto then life is somewhat easier. If it’s only manual, then you have your work cut out. With the help of the ‘third hand’ of the double-ender, significantly makes a rescue easier, whilst maintaining a constant ambidextrous contact of the victim’s loop in their mouth, with the other hand to navigate between rescue diver’s inflation/vents and victim’s counterlung and oxygen MAV.\nAs mentioned earlier, practice doesn’t make perfect, only permanence.\n\nGarry Dallas  \nhttps://simplysidemount.com","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":880493,"hash":"b16f21178342d3d5a8846aa58c66be66cc1d3b11","i

Factors such as the cylinder sizes, depth, and breathing rate play a significant role in determining how long your diving tank will last.","content":"## Key Factors Affecting Scuba Diving Oxygen Tank Time \n\nThe time a scuba tank lasts underwater depends on multiple variables: \n\n1. **Tank Size**: The standard scuba tank size is typically 80 cubic feet of compressed air at 3,000 psi, or a 12-liter tank pressurized to 230 bar. Smaller or larger tanks are available to cater to different diving needs, including smaller aluminum tanks for shorter dives or high-capacity steel tanks for extended underwater explorations. \n\n2. **Depth**: As depth increases, so does the pressure, leading to a higher air consumption rate. For example, the pressure doubles at 33 feet (10 meters) underwater, meaning you consume air twice as fast as at the surface. This is because you need to consume gas at the same pressure as your surroundings \n\n3. **Breathing Rate**: A diver's breathing rate, measured as Surface Air Consumption (SAC), varies based on factors like fitness, stress levels, and underwater activity. A relaxed diver can extend their diving air tank time significantly compared to a stressed one. \n\n![Divesoft rebreather divers](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5b1c8483d492ff8e7e567c4adc7fe46224bc2368_divesoft-photo-056.jpg)\n\n## Calculating Scuba Tank Time \n\nTo estimate how long your diving oxygen tank will take, a scuba tank time calculator can be invaluable. Here's a simplified method: \n\n1. Determine your SAC rate. For example, if you consume 0.5 cubic feet of air per minute at the surface, your SAC rate is 0.5. The same process will work if you like to measure your SAC in liters \n\n2. Factor in depth pressure. At 66 feet (20 meters), the pressure is three times that of the surface. \n\n3. Calculate tank duration.  \n\n- Air per minute = SAC rate × depth pressure. \n\n- Total time = Tank capacity / Air per minute. \n\n- Using an 80 cubic foot tank at 3,000 psi: \n\n A diver with a SAC rate of 0.5 at 66 feet would consume 1.5 cubic feet of air per minute. With an 80 cubic foot tank, they’d have about 53 minutes of dive time (80 / 1.5). \n\n- Using a 12-liter tank at 230 bar: \n\n A diver with a SAC rate of 20 liters at 20 meters would consume 60 liters of air per minute. With 2760 liters in their tank, they would have about 46 minutes of dive time (12*230/60) \n \n## Quick note about rebreathers \n\nIf you decide to dive with a [closed-circuit rebreather](https://eshop.divesoft.com/products/ccr-liberty) your consumption will no longer be determined by your SAC rate, but by the speed at which your body metabolizes oxygen. When using a rebreather, you don’t need to consider the aspect of depth. \n\nIf we use the same calculation we used above, but now for rebreathers: \n\n- Using a 3-liter tank at 300 bar: \n\n A diver with a metabolic consumption of 1 liter per minute will consume the 900 liters of oxygen in their tank in 900 minutes, independent of the depth. \n\nThis number is so high that the diver will frequently be limited by other factors, like scrubber duration or cold exposure, rather than by the gas they carry. This, however, goes beyond the scope of this article. If you want to learn more, you can read our post about our [scrubber duration research](https://www.divesoft.com/en/blog/how-do-we-test-each-ccr-liberty). \n\n![Divesoft rebreather divers](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/f6d8546c95140e38b01937728586f1ede0608aae_divesoft-photo-060.jpg)\n  \n## Scuba Tank Setup and Maintenance \n\nA reliable scuba tank setup is vital for safe and enjoyable diving. Key components include: \n\n**Valve System**: Ensures smooth air delivery. \n\n**Regulator**: Controls the pressure and supplies breathable air. \n\n**Gauge**: Monitors air pressure to track remaining tank time. \n\nPro

2per maintenance of your diving air tank extends its lifespan. Always rinse the outside of your tank with fresh water post-dive and store it in a cool, dry place.\n\n## Enhancing Dive Time Efficiency \n\nTo maximize your scuba diving oxygen tank time: \n\n- Maintain a slow, steady breathing pattern. \n\n- Practice buoyancy control to minimize unnecessary movements. \n\n- Avoid overexertion and stay relaxed. \n\n![Divesoft Analyzer Solo](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/af78e595d510279d65f005d95958e0607a4318c8_divesoft-photo-099.jpg)\n\n## Conclusion \n\nUnderstanding the nuances of your scuba tank, including the standard scuba tank size and variables affecting air consumption, is essential for planning a safe dive. Whether using a single diving tank or engaging in double tank diving, careful preparation and the use of a scuba tank time calculator can ensure a seamless underwater experience. By mastering your equipment and diving techniques, you’ll make the most of your underwater adventures while prioritizing safety.

There are many ways of dividing up scuba diving. The most common are recreational and technical, by the target of the dive, by the environment of the dive, and much more. Bellow we will explore the different types, and highlight their key features.","content":"## Recreational Diving \n\nRecreational diving is the most common type of scuba diving, designed for enjoyment rather than professional or scientific purposes. Divers typically stay within the limits of open water diving depth, which is generally up to 40 meters (130 feet). This category includes activities like: \n\n### Night Diving \n\nExploring underwater environments after sunset, where specialized equipment like dive lights reveals nocturnal marine life. \n\n### Wreck Diving \n\nInvestigating sunken ships, planes, or other man-made structures, offering a mix of history and adventure. \n\n### Drift Diving \n\nLetting the current carry you along, providing a unique way to explore large areas with minimal effort. \n\n![CCR Liberty diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/0e9ff28f763d135cd08782af86003cc1695cd236_divesoft-photo-189.jpg)\n\n## Technical diving \n\nThe definition of [technical diving](https://www.divesoft.com/en/blog/what-is-technical-diving) can be fuzzy at times. There are multiple schools of thought, but they almost all agree that technical diving involves diving in an overhead environment, an environment in which the surface is not directly accessible. Or when mixtures other than air, or sometimes nitrox, are used. \n\n## Rebreather Diving \n\n[Rebreather diving](https://www.divesoft.com/en/products/ccr-liberty) is a subset of recreational diving that uses advanced equipment to recycle exhaled air, allowing for longer dives and reduced bubble production. This technology is ideal for photographing marine life, exploring fragile ecosystems without disturbing them, or diving for extended periods. \n\n## Scientific Diving \n\nScientific diving involves underwater research and data collection, often conducted by marine biologists, archaeologists, or geologists. These dives require specialized training and equipment to ensure safety while performing tasks such as sample collection, habitat surveys, and underwater photography. \n\n![CCR Liberty diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/bdd08049f7155191bb0994380d616a238a68dbb8_divesoft-photo-186.jpg)\n\n## Cave Diving and Cavern Diving \n\nCave diving involves exploring underwater caves beyond the reach of natural light, often requiring specialized gear and training. Cavern diving, a less advanced version, stays within the light zone and is more accessible to intermediate divers. \n\n![CCR Liberty diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/6a53b1ecf4349e89ecbd0da955b07c6ba55e1993_divesoft-photo-183.

2jpg)\n\n## Deep Sea Diving \n\n[Deep sea diving](https://www.divesoft.com/en/blog/what-is-deep-diving) pushes beyond recreational diving limits, often exceeding depths of 40 meters. This type of diving requires technical training and specialized equipment to handle increased pressure and decompression stops. \n\n## Rescue Diving \n\nRescue diving focuses on training divers to manage emergencies underwater and assist other divers in distress. This type of diving is a critical skill for advanced divers and diving professionals. \n\n## Ice Diving \n\nIce diving takes place beneath frozen surfaces, offering a unique and challenging experience. Divers must cut an entry hole in the ice and rely on safety lines to navigate the cold, dark waters. \n\n## Altitude Diving \n\nAltitude diving occurs at locations above 300 meters (1,000 feet) sea level, such as mountain lakes. The reduced atmospheric pressure at these altitudes requires adjustments to dive planning and decompression. \n\n## River Diving \n\nRiver scuba diving, or simply river diving, involves navigating freshwater rivers, often with strong currents. This type of diving is excellent for exploring unique ecosystems and submerged artifacts but requires careful planning and drift-diving techniques. \n\nDiving is a very diverse sport, and it requires proper training and [equipment](https://eshop.divesoft.com/) to practice it safely.

Also known as a **diving computer** or **scuba dive computer**, this device continuously calculates and displays critical dive information, reducing the risk of decompression sickness. Some computers also allow the divers to 

2store a range of gases used during diving, alerting them about when to switch between them, shortening their decompression time.","content":"## How Does a Dive Computer Work? \nThe primary function of a **dive computer** is to track a diver’s depth and the dive time, applying decompression algorithms, such as the [Buhlmann decompression algorithm](https://en.wikipedia.org/wiki/B%C3%BChlmann_decompression_algorithm) to calculate nitrogen or other inert gas absorption and the decompression profile the diver should follow. This allows for real-time adjustments to a diver’s ascent profile, making dives safer and more efficient compared to traditional dive tables. \n\n## Choosing the Best Dive Computer \nWhen looking to **buy a dive computer**, divers should consider factors such as display readability, battery life, and algorithm options. **Dive computer reviews** highlight popular models, from entry-level devices to advanced **tech dive computers** used for deep or mixed-gas diving. Some well-known brands include Suunto, Shearwater, and [Divesoft Freedom](https://www.divesoft.com/en/products/freedomplus-computers), which is highly regarded among technical divers for its customizability and ruggedness. \n\n![Dive computer](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/60b605819cc0c7cd3cb6c1913427369c2b2b70c5_what-is-a-dive-computer-01.jpg)\n\n## Features of a Dive Watch Computer \nMany modern **dive computers** double as wristwatches, making them convenient for everyday wear. A **dive watch computer** typically includes air and nitrox compatibility, wireless air integration, and customizable alarms. They are however built as a wat

2ch first and a dive computer second. They might be sufficient for easier dives, but serious divers appreciate the readability, reliability and advanced features of dedicated dive computers \n\n## Advanced Dive Computer Software  \nModern **dive computer software** allows divers to log and analyze their dives by syncing data to a computer or smartphone. This also includes pre-dive planning where the diver can verify their dive plan, making sure their gases are sufficient and that their diving computer will take the correct amounts of gas into account when planning a dive. Modern dive computers can also take your surface air consumption (SAC) rate into account when planning dives, making sure that each diver has enough gas, no matter the dive. \n\n![Dive computer](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/3d8162718eaa24483e69eac35c5d2beb7e940bca_what-is-a-dive-computer-02.jpg)\n\n## Dive Computer Accessories \nThe best dive computer accessory is a second dive computer, ensuring redundancy during difficult dives.

These bubbles can cause severe pain, neurological issues, and other complications. \n\n## What is the Bends Caused by Scuba Diving?\nDecompression sickness is caused by badly controlled ascents. When a diver descends, the pressure increases, causing nitrogen from the gas they breathe to more easily dissolve into their tissues. If a diver surfaces too quickly, the rapid pressure decrease causes the nitrogen to form bubbles in the tissues and bloodstream. These bubbles cause the symptoms of decompression sickness. \n\n![Rebreather diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/43d91384968f50b68ebe55ba73da4fb2542dc8a2_divesoft-photo-072.jpg)\n\n## How Do You Get the Bends Diving?\nThe bends occurs when divers: \n- Surface too quickly after a dive. \n- Exceed safe dive times or depths outlined in dive tables. \n- Fail to follow proper decompression stops during deep or prolonged dives. \n- Dive multiple times in a day without adequate surface intervals. \n\nNon diving issues include: \n- Dehydration. \n- Poor physical fitness. \n\n## How long should I wait between diving and flying?\nAfter diving, it is essential to wait enough time before flying to reduce the risk of decompression sickness. The general guidelines are: \n\nWait at least **12 hours** after a single no-decompression dive. \n\nWait **18-24** hours after multiple dives or dives requiring decompression stops. Flying soon after diving exposes you to lower air pressure, increasing the risk of nitrogen bubbles forming in your bloodstream, much like a quick ascend would. \n\n## What Is Decompression Sickness?\nDecompression sickness is a medical condition resulting from the formation of nitrogen bubbles in the body. Symptoms include: \n- Joint and muscle pain. \n- Dizziness, nausea, and fatigue. \n- Skin rashes or itching. \n- Neurological symptoms like confusion or paralysis in severe cases. \n\n\n![Rebreather diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5d3c503908977662655bd048f84503d058a5d98a_divesoft-photo-079.jpg)\n\n## Why Is Decompression Sickness Called the Bends?\nThe nickname \"the bends\" stems from the posture divers often assume when suffering from the condition. Severe joint pain, particularly in the knees and elbows, can cause divers to hunch or bend over in discomfort. \n\n## Long-Term Effects of Decompression Sickness\nWhile many divers recover fully with prompt treatment, severe or untreated cases of decompression sickness can lead to lasting effects, including: \n- Chronic joint pain or arthritis. \n- Neurological damage, such as memory loss or motor function impairment. \n- Pulmonary complications. \n- Death \n\n## How to Treat Decompression Sickness\nTreatment for decompression sickness typically involves: \n- Administering oxygen: Pure oxygen helps reduce nitrogen levels in the body. \n- Recompression therapy: This involves placing the affected diver in a hyperbaric chamber to simulate pressure at depth and gradually reduce it, allowing nitrogen bubbles to dissolve safely. \n- Hydration and rest: Supp

It involves diving to greater depths, exploring underwater caves, shipwrecks, or other challenging environments, and often requires advanced training, equipment, and planning. Technical diving opens the door to deeper underwater exploration but comes with higher risks and demands a higher level of expertise. \n\nThe exact definition of what technical diving is can vary. Some define it as diving with mixtures other than air, some define it as diving in an overhead environment (such as caves, wrecks, or dives where decompression occurs). ","content":"## Key Features of Technical Diving \n\nTechnical diving is distinct from recreational diving in several ways: \n\n- **Depth Limits**: Recreational divers are typically limited to a maximum depth of 40 meters (130 feet). In contrast, technical diving depth limits can exceed 100 meters (330 feet) depending on the diver’s training and the [type of dive](https://www.divesoft.com/en/blog/what-are-the-types-of-scuba-diving) being conducted. Diving to such depths requires careful planning to manage decompression stops, gas mixtures, and equipment configurations. \n- **Specialized Equipment**: Technical divers often use advanced gear, including:   \n\t- Twin tanks or [rebreathers](https://eshop.divesoft.com/products/ccr-liberty) for extended underwater time.  \n\t- Multiple stage tanks with different gas mixes for varying depth levels or for decompression.  \n\t- Redundant safety systems to minimize risk. \n- **Complex Dive Planning**: Tech diving involves meticulous preparation, including detailed dive plans, gas management, and contingency strategies to address potential emergencies. \n\n- **Challenging Environments**: Technical diving often takes place in unique and demanding locations, such as:  \n\t- **Cave diving**: Exploring underwater cave systems requires exceptional navigational skills and specialized training.  \n\t- **Wreck diving**: Investigating sunken ships offers a glimpse into history but can involve tight spaces and unstable structures.  \n\t- **[Deep sea diving](https://www.divesoft.com/en/blog/what-is-deep-diving)**: Descending to extreme depths unveils environments rarely seen by humans. \n\n![Rebreather diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/6a53b1ecf4349e89ecbd0da955b07c6ba55e1993_divesoft-photo-183.jpg)\n\n## Training and Certification \n\nTo embark on technical diving, divers must undergo rigorous training and get appropriate certifications. These certifications teach divers advanced skills, such as: \n\n- Decompression procedures \n- Gas blending for mixed gases (e.g., trimix, heliox) \n- Use of technical diving hand signals to ensure clear communication underwater \n- Emergency protocols for handling equipment failures or lost gas supplies \n\n**Tech Diving Courses** are progressive, starting with entry-level certifications like \"Intro to Tech\" or \"Advanced Nitrox,\" and advancing to specialties such as cave diving or rebreather training. Each course builds on foundational skills, ensuring divers are prepared for the challenges of technical dives. \n\n![Rebreather diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/89ae96a7f1708589fffb555337b4f982fba705b1_divesoft-photo-074.jpg)\n\n## The Role of Technical Diving Hand Signals \n\nCommunication is crucial in technical diving, where voice communication is impossible, and visibility may be limited. Technical diving hand signals go beyond the basic signals used in recreational diving. These signals convey critical information, such as: \n\n- Gas-switch notifications \n- Emergency indications (e.g., out of air, low on gas) \n- Depth or time reminders \n- Navigation instructions in caves or wrecks \n\nDivers must master these signals to ensure effective teamwork and safety. \n\n![Rebreather diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/32cb984085d4ad582d6f39aa821b051534d63cce_divesoft-photo-185.jpg)\n\n## The Allure of Technical Diving \n\nThe appeal of technical diving lies in its ability to take divers where few have ventured. Exploring the depths of a wreck or navigating intricate cave systems offers unparalleled excitement and discovery. However, it’s not for everyone; the financial cost, physical demands, and inherent risks make it a pursuit for dedicated and well-prepared individuals. \n\n## Conclusion \n\nTechnical diving, or tech diving, represents the pinnacle of underwater exploration, offering divers the opportunity to push beyond traditional limits. With the right training, equipment, and mindset, technical diving can unlock incredible underwater adventures, from the depths of the ocean to the hidden chambers of underwater caves. For those seeking to go deeper—both physically and metaphorically—technical diving is the ultimate journey.","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":1126777,"hash":"fe3825115a4295950f67e1b253e44bc7296c8424","id":"cm71qowyei9vz0850rxhmbjk5","filename":"what-is-technical-diving-00.jpg","category":"divesoft/","type":"image","alt":"What is Technical Diving?"},"publishDate":"02/19/2025"},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

The lake spans 46.7 km² and stretches 20 km from north to south, with a maximum depth of 170 meters. It lies at an altitude of 476 meters. Its clear waters attract divers from many neighboring countries. For the [Kapr Divers](https://www.kaprdivers.cz) team from Prague, Czech Republic, Attersee is almost a home site. Just 350 km away, we make an average of ten multi-day trips here each year.  \n\n![Chevrolet Mastery - Martin Mako Janecek](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/06e024d94fa806db0dafa20be5bc076389498003_chevrolet-mastery-50m-photo-martin-mako-janecek-diver-tomas-janulik-1.png)\nIn summer, the shallow, warm waters provide an ideal environment for beginners to develop their skills and observe aquatic life, such as lush plants, perch, pike, and, with some luck, eels. The deeper zones, however, offer fantastic opportunities for technical dives. Depths between 30 and 100 meters maintain low temperatures year-round but often provide excellent visibility exceeding 20 meters. For deeper dives, we choose locations with rocky walls, allowing us to descend quickly. While the underwater rocky landscapes are stunning, this year, our exploration of deeper areas had another purpose: searching for 80-year-old car wrecks.  \n\n![Chevrolet Mastery - Martin Mako Janecek](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/ad45a6c5ac68e8377f175eeab44212653e08352a_chevrolet-mastery-50m-photo-martin-mako-janecek-diver-tomas-janulik-2.png)  \n\n## The History of Attersee and Its Wrecks\nThe area around Attersee has been inhabited for over 

26,000 years, as evidenced by archaeological finds. In prehistoric times, stilt houses stood along its shores, forming small villages. The remains of these stilt dwellings, found in several Alpine lakes, are part of a UNESCO World Heritage Site. Although the lake no longer freezes over in winter, historical records show that it was last completely frozen from January 29 to March 31, 1963. This could explain some of the wrecks, possibly from cars falling through the ice. However, this remains unconfirmed, as does the theory of accidents involving cars plunging off the road into the water.  \n\n![Chrysler - Petr Slezak](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/d829c28dc09fa18211643e77d3efb5577abe239e_chrysler-92m-photo-petr-slezak-diver-maggie-feldekova.png)\n\n## Wreck Diving at Attersee\nThe lake’s southern region hosts several car wrecks, accessible from shore at locations like Wandl and BMW Dixi. To date, we’ve mapped four car wrecks in this area. Two shallow ones (a BMW Dixi and a Jeep) are in depths of 5 and 12 meters.  \n\n![Steyr Baby - Petr Slezak](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/a7de8b3a4e0a2cbd68618de74ad398ac4ce6ec3e_steyr-baby-62m-photo-petr-slezak-1.png)  \n\nThey are nearly disintegrated and will likely vanish entirely in a few years. The most intact and visually striking wreck, in my opinion, is the Steyr Baby, lying at 62 meters. This car, manufactured in the 1940s, is remarkably preserved. It still has its wheels, front window, headlights, part of the steering wheel, and dashboard. It rests on a slope with fine sediment, where one careless movement can reduce visibility to zero.  \n\n![Steyr Baby - Petr Slezak](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/2141ac7da3c6c8e9a776c4484f7efe9d106cc3f0_steyr-baby-62m-photo-petr-slezak-2.png)  \n\nAnother wreck in this area is a Chevrolet Master at 50 meters. While well-preserved, it’s not as intact as the Steyr Baby. Missing its wheels, the wreck shows damage on the passenger door and rear fender, suggesting a possible road accident. A few meters shallower are the remains of a truck, which we’ve yet to explore in detail.  \n\n![Steyr Baby - Petr Slezak](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/4b781e26f4143765501b56bac40b1f5c9282d5bf_steyr-baby-62m-photo-petr-slezak-3.png)  \n\nIn the eastern part of the lake, near Schwarze Brücke, two wrecks lie side by side at a depth of 92 meters. One is a Volkswagen Kübelwagen, a military vehicle produced between 1940 and 1945. The other, leaning against the Volkswagen on its deeper side, is a Chrysler from around 1930.  \n\n![Chrysler - Petr Slezak](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/543bf21da56784a9a16a7acbde9cf527d16eb25a_chrysler-92m-photo-petr-slezak.png)  \n\nDiving in such cold waters and depths requires advanced training, proper education, and reliable equipment. Experience with dry suits and hypoxic trimix gases is essential. For exploring Attersee’s deep waters, our team relies on [Divesoft Liberty rebreathers](https://www.divesoft.com/en/products/ccr-liberty). When diving beyond 60 meters, we streamline logistics by using two rebreathers: one as the primary device and the other as a [bailout](https://www.divesoft.com/en/products/ccr-liberty/bail-out-rebreather).\n\n![Steyr Baby - Petr Slezak](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/75f4d217932b02689c9e7f220bb7b4229950ced1_steyr-baby-62m-photo-petr-slezak-diver-tomas-janulik.png)  \n\nAbout the Author:\n\n[Petr Slezák](https://www.divesoft.com/en/ambassadors/petrslezak)  \n[facebook.com/petr.slezak.kapr.divers](https://www.facebook.com/petr.slezak.kapr.divers)\n\n![Petr Slezak](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7803304cc391e542a1a50ad76faec34bbb042fcb_lake-attersee-petr-slezak.png)  \n\n  \nCzech version:\n\n## Vraky starých aut v jezeru Attersee \n \nPo několika minutách plavání v mělké vodě se dostáváme ke kolmé skalní stěně. Vyměníme si signál OK a zahájíme sestup. Je léto, voda má na hladině 21 °C, ale s přibývající hloubkou teplota klesá. Zato viditelnost se zlepšuje. V 92 m je úplná tma, teplota 5 °C a viditelnost více než 20 m. Kontrolujeme bailout rebreathery a úzkými kužely našich svítilen pátráme kolem sebe. 

2Vydáme se naplánovaným směrem a po pár minutách se ze tmy vynoří obrysy toho, co hledáme. Máme radost, voláme na sebe, což tlumí ústenky a zkresluje helium v dýchací směsi, ale našli jsme to. Vrak starého auta je přímo před námi.  \n \nJezero Attersee je třetí největší jezero v Rakousku. Nachází se ve spolkové zemi Horní Rakousko v oblasti zvané Solná komora. Rozloha jezera je 46,7 km², od severu k jihu měří 20 km. Max. hloubka je 170 m. Leží v nadmořské výšce 476 m. Jeho čistá a světlá voda láká potápěče z mnoha okolních zemí. Pro tým Kapr Divers z Prahy, CZ je jezero téměř domáckou lokalitou. S dojezdovou vzdáleností 350 km k jezeru vyrážíme na několikadenní výlety průměrně dest krát do roka. Mělká a teplá voda je v létě ideálním prostředím pro trénink začátečníků, kteří zde mohou rozvíjet své dovednosti a pozorovat vzrostlé vodní rostliny, okouny, štiky a s trochou štěstí i úhoře. Hlubší zóny přináší skvělou možnost pro technické ponory. V hloubkách mezi 30 až 100 metrů je celoročně nízká teplota, ale zpravidla vynikající viditelnost, mnohdy přesahující 20 m. Pro ponory do větších hloubek volíme lokality se skalnatými stěnami, abychom se do hloubky dostali relativně rychle. Samotné skalnaté podvodní scenérie jsou úchvatné, ale letos jsme se věnovali průzkumu hloubek z jiného důvodu. Hledali jsme 80 let staré vraky. Vraky aut. \n \nOblast okolo jezera byla osídlena dle archeologických nálezů již před 6000 lety. Podél břehu jezera, které má ledovcový původ, stála v prehistorickém období obydlí na kůlech a tvořila malé vesnice. Jejich pozůstatky můžeme na několika místech v jezeře vidět dodnes. Tato kůlová obydlí vyskytující se i na jiných místech v Alpách byla zařazena na seznam Světového dědictví UNESCO. Jezero v současnosti v zimě nezamrzá, ale v historii tomu mohlo být jinak. Důvodem je jednak velký objem, který zabraňuje rychlému ochlazení, ale také obsah minerálů a soli ve vodě. Podle místních kronik bylo jezero naposledy zamrzlé souvislou ledovou pokrývkou od 29. ledna do 31. března 1963.  \nJednou z příčin, proč jsou na dně jezera vraky aut, je hypoteticky i to, že se pod nimi prolomil led. Hypotéza je nepotvrzená stejně jako nehoda na silnici a následný pád do vody. \n \nV jižní části jezera se nachází hned několik vraků aut. Dostupné jsou ze břehu z lokalit Wandl a BMW Dixi. Zmapované máme k dnešnímu dni v této oblasti 4 vraky aut. Ty dva mělké (BMW Dixi a Jeep) jsou již téměř rozpadlé a za pár let z nich pravděpodobně nezbyde již vůbec nic. Jsou v hloubkách 5 m a 12 m. Z mého pohledu nejzachovalejší a na pohled nejhezčí je vrak Steyr Baby v hloubce 62 m. Je velmi zachovalý. Nikdo neví, jak dlouho je pod vodou, ale vyráběl se ve 40. letech minulého století. Dodnes má kola, přední okno, světlomety, část volantu i palubní desku. Leží ve svahu s velmi jemným sedimentem a tak stačí jeden neopatrný pohyb potápěče a viditelnost klesne na nulu.  \nDalší vrak auta v této lokalitě je Chevrolet Master v hloubce 50 m. Je také dost zachovalý, vč. volantu, ale ne tak, jako Steyr Baby. Chybí kola a na pravé straně na dveřích spolujezdce a na pravém zadním blatníku jsou viditelná poškození, takže v tomto případě se spíše přikláním k nehodě na silnici (nachází se přímo u břehu). Jen o pár metrů mělčeji od tohoto vraku jsou zbytky nějakého nákladního auta, ale to budeme muset teprve prozkoumat. \n \nVe východní části jezera poblíž lokality Schwarze brucke jsou v hloubce 92 m dva vraky aut bezprostředně vedle sebe. Leží ve svahu. Ten blíže ke břehu je vrak Volkswagen Kübelwagen, což byl vojenský osobní automobil vyráběný mezi lety 1940 a 1945. Druhý vrak opírající se o hlubší stranu Volkswagenu je Chrysler, model vyráběný kolem roku 1930. \nPotápění ve studené vodě do takových hloubek klade vysoké nároky na trénink a vzdělání potápěčů, jakož i na jejich vybavení.

","perex":"Nitrox diving, also known as enriched air nitrox (EANx) diving, is a form of scuba diving that uses a gas mixture containing more oxygen and less nitrogen than standard air. Traditional compressed air contains approximately 21% oxygen and 79% nitrogen, whereas nitrox typically contains between 32% and 36% oxygen. This alteration in gas composition allows for longer bottom times and reduced nitrogen absorption, making it a popular choice among recreational and technical divers.","content":"![Rebreather diver](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/6a53b1ecf4349e89ecbd0da955b07c6ba55e1993_divesoft-photo-183.jpg)\n\n## Benefits of Nitrox Diving\nOne of the primary advantages of nitrox diving is the reduced nitrogen intake, which lowers the risk of decompression sickness (DCS). Divers using enriched air nitrox can extend their no-decompression limits (NDLs), allowing for longer dives at moderate depths. Additionally, since there is less nitrogen in the gas mixture, divers often experience less fatigue after multiple dives. \n\n## Nitrox Diving Calculations\nDiving with nitrox requires specific calculations to ensure safety. These calculations include: \n\n- **Maximum Operating Depth (MOD):** The depth limit where the partial pressure of oxygen (PPO2) does not exceed a safe threshold, typically 1.4 to 1.6 ppO2 (partial pressure of oxygen) for recreational diving. \n\n- **Equivalent Air Depth (EAD):** A formula that helps divers determine the nitrogen exposure equivalent to diving on regular air. \n\n- **Oxygen Exposure Limits:** Managing oxygen toxicity risks by monitoring cumulative exposure over time. \n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/373feac1ea6abe41b464d3120a0c29839a786072_divesoft-photo-181.jpg)\n\n## Essential Nitrox Diving Equipment\n- **Gas Analyzer:** A handheld [device](https://www.divesoft.com/en/products/analyzers) used to measure the oxygen content in a nitrox tank to ensure the mixture is safe for the planned dive. \n\n- **Nitrox Regulator:** A regulator rated for oxygen-rich environments to prevent ignition risks associated with high oxygen concentrations. \

2n\n- **Diving computer:** A [computer](https://www.divesoft.com/en/products/freedomplus-computers), that can help you track your depth, oxygen exposure and dive time is invaluable for safe diving \n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/0362a462a7b830aa64aa8c70c5d1e0441dcd56f8_divesoft-photo-188.jpg)\n\n## Scuba Nitrox Certification and Training\nTo safely dive with nitrox, divers must complete a **scuba nitrox certification** course. This **nitrox diving course** covers essential topics such as gas composition, physiological effects, dive planning, and emergency procedures. Most major scuba certification agencies offer nitrox training, often available as an add-on to standard open-water certification.  \n\n![Divesoft Analyzer Solo](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/af78e595d510279d65f005d95958e0607a4318c8_divesoft-photo-099.jpg)\n\n## Nitrox vs. Air:\nWhen comparing **nitrox vs. air**, the choice depends on the dive profile. Nitrox is advantageous for reducing nitrogen exposure and extending bottom times, making it ideal for multiple dives per day or prolonged moderate-depth dives. However, nitrox is not suitable for deep diving beyond its MOD (maximum operating depth) due to increased oxygen toxicity risks. Standard air remains the better choice for deeper dives up to the depth of 40 meters.  \n\n## Conclusion\nNitrox diving is a valuable tool for divers seeking extended [bottom times](https://eshop.divesoft.com/freedom-full-trimix-computer/8457) and reduced nitrogen exposure. However, proper training, equipment, and calculations are essential to ensure safety. By obtaining a **scuba nitrox certification** and using the appropriate gear, divers can maximize the benefits of enriched air nitrox while minimizing potential risks.","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":2194805,"hash":"4d8ef826e0568edcc8a556f2bc9feeb68fe4f820","id":"cm7w27ex82d3s0850dr3brivx","filename":"nitrox-diving-00.jpg","category":"divesoft/","type":"image","alt":"What is Nitrox Diving?"},"publishDate":"03/05/2025"},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#21","type":"component","lock":false,"position":17},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/@divesoft_tv","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]","twitterUrl":{"url":"","urlNewWindow":true,"pageId":"cjv3l26tp004p0836i54n4u7a"}},"id":"#1","type":"component","lock":false,"position":18}],"id":"root","idBuffer":"#37","lastCommit":"357f3011-9113-4fe7-b174-c721968a1d32"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cm8ptyp2v9lgb0803u3ba0ha0":{"id":"cm8ptyp2v9lgb0803u3ba0ha0","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[{"type":"id","generated":false,"id":"Tag:cjv3szrcv01bz0836yo8myb0r","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww0t651b710803pcl02cn4","typename":"Tag"}],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cm8ptyp3b9lgi0803wu86q6b7","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cm8ptyp3b9lgi0803wu86q6b7":{"id":"cm8ptyp3b9lgi0803wu86q6b7","name":"Cave diving","createdAt":"2025-03-26T11:17:30.887Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

Unlike traditional open-water diving, cave diving requires specialized skills, advanced training, and specific cave diving equipment to navigate submerged passages safely. This article explores the essentials of cave scuba diving, including the different types, required training, safety precautions, and why cave diving is considered one of the most extreme underwater activities.","content":"![Rebreather diver, cave diving](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/58b56661af83bfc8d3577c391b816976d77303fe_divesoft-photo-050.jpg)\n\n## The Different Types of Cave Diving\n\nCave diving itself is not strictly split into different categories, it itself is a subcategory of SCUBA diving. The most important role of cave diving is played by the caves themselves. Caves in Florida are not the same as caves in France, caves carved out by the sea are going to be different than caves carved out by streams or rivers. There are however a few descriptors that could be used for a cave dive, that most divers will recognize: \n\n- **Freshwater Cave Diving** – Common in karst landscapes, these caves feature crystal-clear water and intricate passageways. \n\n- **Deep Sea Cave Diving** – Involves exploring submerged caves in oceanic environments, often requiring technical diving skills. \n\n- **Exploration Cave Diving** – Pushing the limits of human endurance, this form of diving often involves deep, narrow, or particularly difficult pushes into cave systems. \n\n- **Sidemount Cave Diving** – Using sidemount configurations for better maneuverability in tight spaces. \n\n- **No Mount Cave Diving** – An extreme form of exploration where divers remove their tanks to squeeze through ultra-tight restrictions. \n\n\n![Rebreather diver, cave diving](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c80f20b8f5d2b4541f0994d21cd108dc10e52be0_divesoft-photo-063.jpg)\n\n## Cave Diving Training and Certification\n\nCave diving is not for beginners. It requires rigorous cave diving training from a capable instructor and a certification from a recognized authority. A cave diving course typically includes: \n\n- **Diving in a Cave Environment** – Learning to navigate, plan, and execute dives safely. \n\n- **Cave Diving Equipment Usage** – Mastering specialized gear such as a cave diving rebreather, cave diving helmet, and primary and backup lighting. \n\n- **Cave Diving Reel Handling** – Ensuring a secure route back to the entrance. \n\n- **Cave Diving Rescue Techniques** – Essential skills to handle emergencies in confined underwater spaces. \n\n![Rebreather diver, cave diving](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/6a53b1ecf4349e89ecbd0da955b07c6ba55e1993_divesoft-photo-183.jpg)\n\n## Essential Cave Diving Equipment\n\nTo ensure safety and efficiency, cave divers rely on a comprehensive cave diving equipment list, which includes: \n\n- **Cave Diving Helmet** – Protects against low-hanging rock formations. \n\n- **Primary and Backup Lights** – Essential for visibility in pitch-black environments. \n\n- **[Cave Diving Reel](https://eshop.divesoft.com/products/reels)** – Used to maintain a guide line back to the entrance. \n\n- **Redundant Air Supply** – Often in the form of sidemount or back-mounted tanks. Many divers also opt to use a rebreather as it drastically extends the time a diver can spend underwater \n\n![Rebreather diver, cave diving](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c0bcdee4b6191886dd4470013c14a784bfbcdb95_divesoft-photo-066.jpg)\n\n## How Dangerous is Cave Diving? Understanding the Risks\n\nMany people ask, **\"Why is cave diving so dangerous?\"** The answer lies in the combination of factors such as confined spaces, lack of direct access to the surface, and the potential for equipment failure. **Cave diving fatalities** often result from poor planning, improper training, or failure to follow safety protocols. \n\nHowever, with proper training, a solid dive plan, and reliable equipment, the risks can be mitigated significantly. Modern advancements in **[cave diving equipment](https://eshop.divesoft.com/products/ccr-liberty)** and **cave diving rescue** techniques have contributed to safer cave diving expeditions worldwide. \n\n![Divesoft Analyzer Solo](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/af78e595d510279d65f005d95958e0607a4318c8_divesoft-photo-099.jpg)\n\n## Cave Diving Facts and Expeditions\n\n- The world’s deepest known cave dive took place in the [Hranická Propast](https://en.wikipedia.org/wiki/Hranice_Ab

2yss) in the Czech Republic. \n\n- Some of the most famous **cave diving expeditions** include explorations of Mexico’s cenotes and Florida’s extensive underground river systems. \n\n- The longest known underwater cave system, Sac Actun in Mexico, stretches over 350 km. \n\n## Conclusion\n\nCave diving is an exhilarating and highly technical activity that requires dedication, proper [cave diving training](https://www.divesoft.com/en/instructors), and [high-quality equipment](https://eshop.divesoft.com/). Whether exploring deep cave diving sites, participating in cave diving expeditions, or mastering the use of a cave diving rebreather, divers must prioritize safety and preparedness. While cave diving fatalities highlight the inherent dangers, understanding and respecting the risks make this sport a fascinating yet demanding endeavor. For those ready to take the plunge, a cave diving course with a reputable instructor is the first step toward unlocking the mysteries of the underwater world.","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":941386,"hash":"f268d5e088887d68d02925dff4677a2b566ea457","id":"cm8pugs8bdbdp0850q7o1ahth","filename":"divesoft-photo-062c.jpg","category":"divesoft/","type":"image","alt":"Cave diving"},"publishDate":"03/27/2025"},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#21","type":"component","lock":false,"position":18},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/@divesoft_tv","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]","twitterUrl":{"url":"","urlNewWindow":true,"pageId":"cjv3l26tp004p0836i54n4u7a"}},"id":"#1","type":"component","lock":false,"position":19}],"id":"root","idBuffer":"#38","lastCommit":"3d7d3078-7978-4724-b4f3-562ba6f99c1c"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cm99l1yayeijj0803qpv7qu1f":{"id":"cm99l1yayeijj0803qpv7qu1f","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[{"type":"id","generated":false,"id":"Tag:cly72rlmrv2ht07358rq07kkr","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww05zc1b5d0803zglvz927","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww0t651b710803pcl02cn4","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cmqtb0dz5gcr90826mxwvssx3","typename":"Tag"}],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cm99l1ybheijq0803f2v8qrfm","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cm99l1ybheijq0803f2v8qrfm":{"id":"cm99l1ybheijq0803f2v8qrfm","name":"How to find a diving buddy for your expeditions","createdAt":"2025-04-09T07:03:29.789Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

Not just someone to enter the water with, but someone they can rely on when things do not go exactly as planned. In diving, we call that person a buddy.\n\nWhether you're exploring a shallow reef, completing your first wreck dive, or preparing for a technical expedition, the person beside you plays an important role in your safety, confidence, and enjoyment underwater.\n\nThe best dive partnerships grow through trust, good communication, and time spent diving together.\n\nIf you are wondering how to find a dive buddy you can trust, the strongest teams are usually built long before entering the water. ","content":"### Why Your Buddy Matters\n\nMost divers learn the buddy system during their first certification course.\n\nAt first, it may seem simple. Stay together, check each other's equipment, and help if something goes wrong.\n\nAs divers gain experience, they begin to understand that a good buddy provides much more than an extra set of eyes underwater.\n\nA trusted partner helps with planning, navigation, problem-solving, and decision-making. They help keep dives enjoyable, reduce stress, and often notice things you might miss yourself.\n\nFor technical and CCR divers, the importance of a reliable partner becomes even more obvious.\n\n*“The importance of a dive buddy returned but with new significance;

2 the bailout gas carried by a buddy is factored into my dive/emergency plan, as my bailout is into his.”*\n— Richie Kohler, expedition wreck explorer\n\nThe deeper the dive and the more ambitious the objective, the more important the team becomes.\n\nBut the principle remains the same at every level of diving.\n\n**Trust matters.**\n\n![Two technical divers with rebreathers together as a trusted buddy team](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/caed3c8a07ce0872691d79edba40947d5c6a8113_liberty-models-story-1_1500_1500.webp)\n \n### What Makes a Good Diving Buddy?\n\nMany divers assume the best buddy is simply the most experienced diver available.\n\nIn reality, strong partnerships are usually built on compatibility rather than impressive certifications or logbook numbers.\n\n#### Similar Experience and Goals\n\nDivers do not need identical certifications, but they should feel comfortable with similar types of dives.\n\nA relaxed reef dive, a deep wreck, and a cave exploration all require different expectations. Good buddies understand what they are trying to achieve and share a similar level of comfort in the environment.\n\n#### Shared Approach to Planning\n\nReliable divers prepare before the dive.\n\nThey discuss objectives, review procedures, and make sure everybody understands the plan. Small conversations before entering the water often prevent misunderstandings later.\n\n#### Compatible Equipment and Procedures\n\nFor recreational diving, a good scuba buddy should understand the dive plan, communicate clearly, and stay within agreed limits.\n\nFor technical and CCR dives, compatibility also includes certification depth, unit familiarity, and decompression discipline. A buddy should be trained for the planned depth, understand the equipment being used, and follow a decompression strategy that fits the team plan.\n\n#### Calm Communication\n\nOne of the most valuable qualities in a diving partner is composure.\n\nWhen something unexpected happens, divers who communicate clearly and remain calm often solve problems more effectively than those with the most impressive certifications.\n \n### Trust Is Built on Small Dives\n\nMany divers meet future buddies online.\nVery few build trust there.\n\nConfidence in a buddy usually develops after spending time diving together.\n\nBefore planning a demanding expedition, a deep wreck dive, or a major CCR project, spend time diving together in less demanding conditions.\n\nA controlled shake-down dive at moderate depth can reveal how a potential dive buddy plans, communicates, checks equipment, and reacts when conditions change.\nA simple local dive often reveals more about a potential buddy than dozens of online conversations.\n\nPay attention to how they prepare, communicate, and react when plans change.\nAfter the dive, talk openly about what went well and what could be improved.\nFor more advanced dives, debriefing can also include SAC rates, bubble checks, dive computer data, or Liberty sensor logs.\nTechnical divers often go one step further by practicing emergency procedures together. \n\nLost-unit drills, bailout scenarios, CO₂ breakthrough drills, light failures, and other exercises help build confidence in the team long before those skills are ever needed. \nThe strongest dive teams are rarely formed overnight.\n\nThey are built one dive at a time.\n \n ![CCR divers descending underwater alongside their buddies.](http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/8ac400255f6b0261b4bb176cb2aa34d707f37e8c_libertydiversclub-02.jpg)\n \n### Where to Find a Dive Buddy\n\nFortunately, divers have more ways than ever to connect with like-minded people.\n\nThere is no single dive buddy finder that works for everyone. Most divers find reliable diving buddies through a mix of local dive centres, clubs, training programs, online communities, social media groups, and repeated dives with people they already know.\n\n#### Local Dive Centres and Clubs\n\nMany divers first get to know future buddies during a course, a club dive, or a trip with a local dive centre. Sharing a boat, a training day, or a weekend diving trip is often how long-term diving partnerships begin. \n\nFor recreational divers, local clubs and dive centres are often the easiest way to meet a reliable scuba buddy gradually. For technical and CCR divers, centres that support CCR fills, trimix fills, or technical charters are especially useful places to meet partners with similar training, equipment, and goals.\n\n#### Online Diving Communities\n\nOnline communities such as ScubaBoard and DiveBuddy include dedicated sections where divers look for training partners, teammates, and expedition companions. \n\nFor technical and CCR divers, these communities can also help connect people with similar equipment, certification levels, and dive objectives. \n\nExample request:\n*“Recent Mod 1 certified on SF2 CCR… another CCR or SCCR diver would be great, but happy to dive with OC.”*\n\nWhen posting a dive buddy request, include the date, location, planned maximum depth, unit or equipment configuration, certification level, and dive objective. Clear details help other divers quickly understand whether the plan fits their skills, experience, and equipment.\n\n#### Social Media Groups\n\nFacebook groups, Discord servers, and Reddit communities focu

2sed on scuba diving, technical diving, and rebreathers can be excellent places to connect with local divers.\nSearching hashtags such as **#CCRLIBERTY** can often lead to active discussions, planned trips, and new diving contacts.\n\n#### Liberty Divers Club\n\nThe Liberty Divers Club connects Liberty CCR owners from around the world. Members regularly share dive plans, organize expeditions, and meet for projects ranging from local dives to major explorations.\n \n#### Dive Events and Training Programs\n\nSome diving partnerships start during training.\nOthers begin at events like Operation CCR, EuroTek, TEKCamp, or Divesoft gatherings, where divers meet people with similar interests and future diving goals.\n  \n### Potential Red Flags\n\nNot every diver is the right teammate.\n\nSome habits are worth noticing early:\n\n* Repeated changes to the dive plan without discussing them with the team\n* Frequent late arrivals or last-minute changes without clear communication\n* Showing up without the equipment or information needed for the planned dive\n* Skipping pre-dive checks\n* Modifying life-support equipment without proper validation\n* Competitive or ego-driven attitudes\nReluctance to discuss mistakes or learn from feedback\n\nMany divers prefer to get to know a buddy gradually through regular dives and time spent underwater together.\n \n### Planning Together\n\nGood teams communicate clearly and plan consistently.\n\nTools such as [Divesoft.app] (https://www.divesoft.com/en/app) help divers share decompression and gas plans, synchronize logs, manage checklists, and review dives together. Working from the same information reduces misunderstandings and helps everyone stay aligned throughout a project.\n\nWhether planning a recreational dive trip or a technical expedition, preparation becomes easier when the entire team shares the same plan.\n \n### The Best Dive Teams Are Built, Not Found\n\nAsk experienced divers how they met their favourite dive buddy and you'll often hear a similar story. Most divers prefer to see how someone plans, communicates, and behaves underwater before relying on them during more demanding dives.\n\nThey usually develop through regular dives, honest communication, and mutual respect.\nTraining, equipment, and experience all contribute to safer and more enjoyable diving.\n\nOver time, most divers come to a similar conclusion.

Choosing the right eCCR isn't just about investing in advanced equipment; it's about maximizing safety, performance, and long-term value. This guide is specifically crafted for technically-minded divers exploring eCCR options, seeking clarity on critical differences between top models like the Divesoft Liberty and its competitors. Dive into the specifics and discover exactly what makes an eCCR system superior.","content":"## Why Choose eCCR Over mCCR?\n\n### Automation and Safety\n\nModern diving technology has dramatically enhanced diver safety through electronic control systems. eCCR systems automatically maintain optimal breathing mixtures, allowing divers to focus on situational awareness and reducing the chance of human error.\n\n### Limitations of Manual Systems\n\nManual CCRs (mCCR), while offering precise control, require constant attention—especially during ascent when oxygen management becomes critical. In emergency situations, task-overload can easily distract divers, increasing the risk of dangerous hypoxia.\n![mCCR scheme](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/f406683e3a0020707c92f047820af8aa847badc1_mccr.png)\n\n### Standard eCCR Systems\n\nStandard eCCRs reduce diver workload by automating oxygen injection based on real-time sensor readings. This allows divers to focus on navigation, buoyancy, and situational awareness. However, many commercially available eCCR models do not offer robust backup systems. In the event of an electronic failure—such as a controller or sensor malfunction—there is often no secondary system to seamlessly take over. This lack of redundancy can place divers at risk, especially during deep or extended dives where bailout options are limited.\n![eCCR scheme](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/62fd4235d5a841f8f324e5650de5e53054d1be71_eccr.png)\n\n### Redundancy in Modern eCCRs\n\nConcerns over electronic failures once favored mCCR systems. However, today’s eCCRs, including the Liberty, incorporate robust redundancy, making them highly reliable even in the rare case of individual system component failure.\n![Fault tolerant Liberty eCCR scheme](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/f8eefd171569f4bd2d86861570dcd1a45c84759f_fault-tolerant.png)\n\n### Hybrid CCRs\n\nHybrid systems (hCCR) combine manual and electronic components. While they use the same constant flow orifice (jet) as mCCR—thus being depth-limited like mCCR—they have an advantage in that the electronics monitor the oxygen partial pressure. However, unlike eCCR systems, these electronics are usually not redundant.\n\n![Rebreather comparison chart](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/691df2fd18b9cee1bf0c1c709751c6f93f35

This [type of diving](https://www.divesoft.com/en/blog/what-are-the-types-of-scuba-diving) includes technical diving, commercial diving, and exploration dives that often require the use of mixed gas breathing systems, rebreathers, and advanced decompression procedures. \n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/9afe8396b03aee84844313c2b9e75f8040ba83f0_divesoft-photo-179.jpg)\n\nHow Deep Can You Go Scuba Diving? \n\nThe depth a diver can reach depen

2ds on training, equipment, and the breathing gas mixture used. \n\n**Recreational scuba diving** is typically limited to **40 meters (130 feet)** using standard air tanks. \n\n**Technical divers** using trimix or other specialized gas blends can exceed **100 meters (328 feet)**. \n\n**Commercial and saturation divers**, who work on deep-sea structures, often reach depths of **300 meters (984 feet)** or more while using advanced diving systems. \n\n**The world record for deep diving on an open-circuit scuba system is 332 meters (1,090 feet)**, achieved by Ahmed Gabr in 2014. \n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/85af94cd0f93661c4e96ea399e26df20b489537a_divesoft-photo-192.jpg)\n\nEssential Equipment for Deep Diving \n\nGoing beyond recreational depths requires specialized equipment to ensure safety and manage the physiological challenges of deep pressure and gas narcosis. Some essential equipment includes: \n\n**Mixed Gas Systems**: Deep dives often require breathing gases like **helium-oxygen (heliox)** or **trimix (helium, oxygen, and nitrogen)** to prevent nitrogen narcosis and oxygen toxicity. Some divers have been experimenting with using more exotic gases, such as hydrogen as a part of their breathing mixture. \n\n**Decompression Computers**: These help divers manage complex ascent schedules to avoid decompression sickness (the bends). They do this by using various tissue saturation algorithms, such as the Buhlman model. \n\n**Rebreathers**: Unlike traditional open-circuit scuba gear, rebreathers recycle exhaled air by removing carbon dioxide and replenishing oxygen, allowing for extended dive times by limiting the gas use to the actual metabolic consumption of the diver. \n\n**Deep Diving Suit**: A crucial piece of gear for extreme depths, deep sea diving suits, such as atmospheric diving suits (ADS), protect divers from immense pressure and enable them to operate at depths of **up to 610 meters (2,000 feet)**. These suits are, however, only rarely used and are saved for extreme conditions. \n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/373feac1ea6abe41b464d3120a0c29839a786072_divesoft-photo-181.jpg)\n\nRisks and Challenges of Deep Diving \n\nDeep sea diving presents unique risks that require careful preparation and adherence to safety protocols: \n\n**Decompression Sickness (DCS)**: Prolonged exposure to high-pressure environments increases inert gas absorption in the body, which must be safely released during ascent. It is important to be weary of aspects such as cold exposure and dehydration which can greatly affect the off-gassing time \n\n**Nitrogen Narcosis**: The onset of this effect is highly personal, some divers can start feeling it at depths of **30 meters (100 feet)**, others start to get “narked” at depths of 50 meters (160 ft). Nitrogen can have an intoxicating effect, impairing judgment, reaction time, and coordination.  \n\n**Oxygen Toxicity

2**: High partial pressures of oxygen at depth can cause seizures, which is why [technical divers](https://www.divesoft.com/en/blog/what-is-technical-diving) use hypoxic gas blends to mitigate this risk. Such blends are not usable in shallower depths, since they do not contain enough oxygen to sustain life at lower pressures. \n\n**Equipment Failure**: At extreme depths, standard scuba gear may malfunction with higher probability, requiring redundancy and backup systems. \n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/adbd8c4a15bc716e89a2dcb620bd10c901fb7dcb_divesoft-photo-101.jpg)\n\nThe Future of Deep Diving \n\nAdvancements in technology continue to push the limits of how deep humans can explore underwater. Innovations in [rebreather technology](https://www.divesoft.com/en/products/ccr-liberty), **diving suits, and remotely operated vehicles (ROVs)** are expanding our ability to explore the depths safely and efficiently.

On a glass‑flat morning with perfect viz, it can be tempting to slip beneath the surface on your own schedule—just you and the blue. Yet that same temptation masks the single greatest preventable hazard in recreational scuba: diving alone. Whether you’ve logged five dives or five thousand, decades of incident reports agree on one thing—most diving fatalities involve factors a buddy or group could have mitigated or prevented.\n\nThis article unpacks the real solo‑diving risks, highlights the practical benefits of group diving, and offers actionable diving safety tips that will make every descent safer … and a lot more fun.\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/bc1ef5d15e01f1907c173cadcee0d21c68b30659_divesoft-photo-173.jpg)\n\n<br>\n\n## 1)  Solo Diving Risks You Can’t Ignore\n**Equipment Failure**  \nA blown O‑ring, stuck inflator, or computer blackout can escalate in seconds when you have no backup. A buddy brings an extra air source, redundant gauges, and two extra hands to fix or abort the dive quickly.\n\n**Medical Emergencies**  \nCramps, sudden fatigue, vertigo, or the first signs of decompression sickness demand immediate aid. A partner can share air, assist a controlled ascent, and administer O₂ topside while summoning further help.\n\n**Navigation Errors**  \nCurrents shift, visibility drops, and compasses occasionally fail. Extra eyes on landmarks and shared decision‑making mean the team is far less likely to be swept off course—or can find its way back together if it is.\n\n**Task Overload & Panic**  \nStress compounds rapidly when every issue is yours alone. A calm teammate can spot the early signs of panic, coach you through problem‑solving steps, and keep the situation from snowballing.\n\n**Delayed Rescue**  \nSurface support may not notice a missing solo diver until it’s too late. Buddy pairs and teams have built‑in check‑in procedures that ensure everyone is accounted for on schedule, drastically shortening response times in an emergency.\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/b0b2fb93fa74d034ce25a8dc18cd59c4c617d7ff_divesoft-photo-178.jpg)\n\n<br>\n\n## 2)  The Big Benefits of Group Diving\n#### 2.1  Exponential Safety\nA group multiplies resources: spare masks, extra SMBs, shared tools, and—most important—additional brains making sound decisions. In a three‑person team, any single catastrophic gear failure still leaves two full gas supplies ready to assist.\n\n#### 2.2  Skills Growth Through Observation\nLearning accelerates when you watch others manage buoyancy, run a reel, or shoot a DSMB. Debriefing as a team turns every dive into a compact workshop where you capture lessons solo divers might never notice.\n\n#### 2.3  Stress Buffer and Mental Bandwidth\nKnowing someone has your back lowers background anxiety, freeing mental cycles for better trim, photography, or simply soaking in the scenery.\n\n#### 2.4  Community and Motivation\nHumans are wired for shared adventure. Group diving builds friendships, fosters mentorship, and fuels the positive peer pressure that keeps you training, logging dives, and exploring new environments.\n\n#### 2.5  Access to Advanced Sites\nMany operators require a minimum of two (often three) divers to charter remote reefs, deep walls, or wreck penetrations. Joining a group literally opens doors solo divers can’t swim through.\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/1dc0

25930c87fbdba1011557fbfd2368c37e7ca04_divesoft-photo-113.jpg)\n\n<br>\n\n## 3)  Real‑World Examples (and One Hilarious Cautionary Tale)\n##### The Stuck Inflator Valve – Cenotes, Mexico.\nA diver’s power inflator jammed fully open at 18 m. His buddy, two meters away, disconnected the LP hose and prevented a runaway ascent—textbook save in ten seconds. Alone, it might have ended in a ceiling impact or embolism.\n\n##### Lost in Kelp – California Channel Islands.\nEven with a compass, a solo diver drifted into heavy kelp and spent critical minutes entangled near the surface surge. A passing three‑person team noticed his frantic bubbles, cut him loose, and escorted him back to the anchor line.\n\n##### Sudden Vertigo – Red Sea Night Dive.\nAn experienced photographer became disoriented and began an uncontrolled descent. His group leader spotted the erratic light beam, arrested the descent, and completed a controlled ascent with a safety stop.\n\n##### The Back‑Zipper Blues – Slapy Reservoir, Czechia (Humour Break).\nAn unnamed friend once drove to the Slapy dam determined to enjoy some peaceful me‑time underwater. He parked on a steep roadside, suited up—and discovered the flaw in his plan: a rear‑entry drysuit zipper. With nobody around to zip him up, he stood on the shoulder hitch‑hiking until a curious driver obliged.  \nZipped at last, he scrambled down the slope to the water… when nature called. Hard. Panicked, he clambered back up, eyes bulging, and flagged another passing car to unzip him. He made it—barely preserving his dignity. Business handled, he hitch‑hiked a third time to get re‑zipped, slid down the bank once more, and finally submerged.\nMoral of the story? Even the most routine solo dive can turn into a slapstick epic when you skip the dive buddy system advantages.\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/150a67340da191d522a11cf0e539491c3c6d49ed_divesoft-photo-141.jpg)\n\n## 4)  Practical Group‑Diving Best Practices  \n**Plan as a Team.**  \nAgree on max depth, bottom time, gas limits, turn pressure, hand signals, and lost‑buddy procedures before you splash.\n\n**Assign Roles. **  \nRotate who leads, who navigates, and who runs the safety‑stop timer. Clear roles prevent “someone else will do it” complacency.\n\n**Stay In Formation.**  \nStandard triangle (three divers) or side‑by‑side (two divers) positions keep everyone in sight and within arm’s reach for air‑sharing.\n\n**Use Compatible Gear.**  \nCheck hose lengths, clip points, and gas mixes to avoid surprises. Agree on a common ascent rate and safety‑stop depth.\n\n**Debrief Honestly. **  \nFive minutes on the surface covering what went right and wrong cements learning and deepens trust.\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/7971289ecd9dfe328cf3c9d631b3a077e370cf2d_divesoft-photo-160.jpg)\n\n<br>\n\n## 5)  Counterarguments—and Why They Fall Short  \n**“But I’m a Self‑Reliant Diver”**  \nThat specialty is about redundancy (two regs, two computers, pony bottle), not rejecting buddies. It prepares you for the rare separation, not routine solo dives. |  \n**“Buddies Slow Me Down”**  \nChoose partners with matching objectives and agree on pace. Efficiency comes from planning, not solitude.  \n**“I Dive Solo for Photography”**  \nA patient buddy can hover behind or above you, acting as a safety lookout while you frame the shot—and even model for scale!  \n**“Groups Cause Entanglement”**  \nProper spacing, trim, and situational awareness prevent this.

The next ten minutes could save you thousands of euros—and, more importantly, keep you breathing easy when you’re 60 m deep.\n\n","content":"> „There is no perfect rebreather, but you can find the right rebreather for you if you are willing to do a little work.“  \n–Jill Heinerth – Canadian cave explorer, filmmaker and author in article „10 Things to Know Before Buying a Rebreather“, DIVER Magazine, 14. 1. 2019\n\n\n### Why choosing the right rebreather matters\n* **Cost of ownership**: €6 000–€12 000 upfront, plus sensors, sorb, servicing, and annual training refreshers  \n* **Risk of malfunction**: PO₂ spikes, flooded scrubbers, or electronics failures don’t forgive sloppy choices  \n* **Long-term commitment**: You’ll train, maintain, and travel with this unit for 5–10 years—make sure it fits you  \n\n*The initial purchase includes everything you need to dive, but consumables—especially sensors and sorb—shift to predictable, recurring costs. Build them into your yearly budget so your life-support system stays reliable and certification-compliant. Both CCR Liberty backmount and Liberty Sidemount arrive with a full set of four oxygen sensors already installed.*\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/bcf5bf2534af7be17211a76d002b29eaae952932_divesoft-photo-146.jpg)\n________________________________________\n### Key CCR rebreather properties to evaluate\n#### 1 Oxygen sensor type & reliability\nThree independent galvanic sensors are the industry minimum. Look for:\n* Automatic voting logic that ignores a rogue sensor\n* User-selectable calibration set-points (0.7 bar & 1.3 bar)\n* Replace-by date stamped < 12 months out\nLiberty spotlight: CCR Liberty doubles down on redundancy with two totally independent control units, each carrying its own battery, depth sensor, and dedicated O₂/He sensor set—so one side can fail while the other keeps regulating the loop oceanquest.se.\n________________________________________\n#### 2 Scrubber duration & performance\nAsk for the CE EN 14143 scrubber test sheet. Compare:\n* Certified duration at 4 °C / 40 m (cold-water worst case)\n* Sorb material (Sofnolime 797 vs. generic)\n* Axial vs. radial canister design—radial gives more even gas flow\nRule of thumb: ≥ 4 h cold-water duration for serious expedition work.\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/37208aeee117c01c883633411589d47483004fa0_divesoft-photo-057.jpg)\n________________________________________\n#### 3 Electronics, HUD & alarms\nYour brain isn’t enough in narcosis. Insist on:\n* Independent primary & secondary computers\n* Full-colour HUD with peripheral-vision LEDs plus tactile or audible alerts\n* Field-swappable battery packs rated to > 70 dives per charge\n________________________________________\n#### 4 Work of breathing (WOB) & comfort\nLower WOB = less CO₂ retention = lower fatigue. Look for:\n* CE test result ≤ 3.0 J/L @ 40 m & 40 RMV (Liberty has 2.16 J/L only!!!)\n* Counter-lung placement that matches your trim (back-mounted for cavers, chest for photogs)\n* Wide-bore hoses to cut flow resistance\n________________________________________\n#### 5 Redundancy & bailout systems\n*\tBailout valve (BOV) integrated—one bite switches to open circuit\n*\tOff-board gas ports for deco or cave cylinders\n*\tSpare controller orterials\nMarine-grade stainless steel, titanium, anodised aluminium, or Delrin, shrug off salt and drops. Carbon fibre for specific applications.\n\n\n**Need a deeper dive?** See our step-by-step method in [How to choose the right CCR rebreather for you](https://www.divesoft.com/en/blog/how-to-chose-the-right-ccr-rebreather-for-you).\n\n![Nazev](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/116c138e2d24d057f6bac82dc01ed81390efbecb_divesoft-photo-124.jpg)\n________________________________________\n\n### Common mistakes when buying a rebreather\n**Case file**: An experienced diver picked a bargain unit lacking local instructors. Six months later his firmware bricked; shipping to the factory cost €500 and delayed a Red Sea trip.  \n1.\tFocusing only on price—cheap today can be lethal tomorrow.  \n2.\tIgnoring training availability—no instructor, no progression.  \n3.\tUnder-estimating maintenance—annual overhauls average €400–€600.  \n\nIf you avoid just one of these pitfalls, this guide paid for itself—underwater and topside.\n________________________________________\n### Final bubbles\nChoosing a CCR is less about brand hype and more about matching hard specs to your diving reality. Evaluate each property methodically, talk to divers who log serious bottom time, and refer back to the checklist before you part with a single euro. CCR Liberty and Liberty Sidemount set a high benchmark—use it to judge every other unit in the showroom.

Read This First\nBefore we plunge into deep end configurations, nail these fundamentals:  \n**1.\tTraining before hardware** – Agencies like TDI, IANTD, BSAC or RAID insist on an air diluent CCR course (Mod 1) before any helium or cave curriculum. A solid foundation needs to be laid before tackling the hard stuff.  \n**2.\tEntry level Liberty package** – The standard Liberty Backmount with 2 × 3 L cylinders, single HUD, and 2 Liberty handsets meets every agency’s starter spec while lightening the rig for skill drills.  \n**3.\tService & mentoring network** – New CCR divers lean on instructor and dealer support. Divesoft’s certified service hubs in 28 countries slash downtime the first time you flood a handset seal.  \n\nKeep these points in mind as you dive into the advanced chapters below; the engineering that keeps Liberty alive at 300 m also rewards your first 40 m deco dive.  \n\n<br>\n\n## What Makes Deep‑Rated CCR Setups Different?\n\n<br>\n\n<div style=\"margin:10px 0; overflow-y: scroll; background:; padding: 10px\">\n  <table style=\"min-width: 700px\">\n    <tr>\n      <td style=\"padding: 10px\" colspan=\"3\">\n        <h3>Deep-Rated CCR Challenges &amp; Liberty Solutions</h3>\n      </td>\n    </tr>\n    <tr style=\"border-bottom: 2px solid gray;\">\n      <th style=\"padding:10px;\">Challenge</th>\n      <th style=\"padding:10px;\">Why It Matters Below 60 m</th>\n      <th style=\"padding:10px;\">Liberty Engineering Response</th>\n    </tr>\n    <tr style=\"border-bottom: 1px solid gray;\">\n      <th style=\"padding:10px;\">High ambient pressure</th>\n      <td style=\"padding:10px;\">Increases work of breathing (WOB) and can collapse loop hoses.</td>\n      <td style=\"padding:10px;\">Sophisticated design and internal aerodynamics keep WOB < 2.4 J/L @ 100 m.v</td>\n    </tr>\n    <tr style=\"border-bottom: 1px solid gray;\">\n      <th style=\"padding:10px;\">Complex gas mixes (trimix / heliox)</th>\n      <td style=\"padding:10px;\">Precise PO₂ control needed to avoid CNS toxicity &amp; ICD.</td>\n      <td style=\"padding:10px;\">4-oxygen-sensor voting (quad-sensor redundancy) &amp; optional helium FO₂ linearization firmware.</td>\n    </tr>\n    <tr style=\"border-bottom: 1px solid gray;\">\n      <th style=\"padding:10px;\">Bail-out logistics</th>\n      <td style=\"padding:10px;\">Open-circuit deco gas at depth is heavy &amp; costly.</td>\n      <td style=\"padding:10px;\">Integrated Bail-Out Valve (BOV) and dual independent scrubbers enable on-board CCR bail-out.</td>  \n\n\t\t\t\n<br>\n\n## Top Liberty CCR Setups for Deep Technical Diving\n\n### 1. Liberty Backmount – The Expedition Workhorse\n**Ideal For**: Trimix divers on multi stage open water descents, liveaboard operations.  \n\n##### Core Specs:\n*\t2.5 or 3.3 kg radial scrubbers \n*\tDual electronics \n*\tIntegrated BOV \n* **Why It Excels:** Familiar twin set trim, easy cylinder switchover, and a backplate that matches standard DIR harness spacing. \n\t\t\t\n![Liberty Rebreather Diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/b7c7fda60728433f44820a88e9477bd780f372fc_divesoft-photo-190.jpg)  \n\n<br>\n\n### 2. Liberty Heavy – All in One Backmount  \n\n**Ideal For**: Divers who prefer a single back mounted system with integrated diluent and bailout, particularly in DIR/GUE style setups.\n#####\tCore Specs:\n* Electronics & scrubber architecture identical to Liberty Backmount)\n*\tCylinder accommodation: twin 7 L or twin 3 L steels plus 3 L oxygen centre mounted\n*\tIntegrated Liberty Heavy backplate & wing (25 kg lift) for familiar twin set trim \n \n#####\tGUE Configuration – 2 × 7 L diluent + 3 L O₂\n**Pros**: All gases on the back; uncluttered chest D rings for stage handling; single gas switch discipline.  \n**Cons**: Truly deep dives (>150 m) still call for extra off board stages; large diluent volume makes mix changes costly; loop diluent use depletes bailout reserve.  \n \n##### Lightweight Configuration – 2 × 3 L diluent\n*\tDrops ~5 kg from rig weight yet keeps Heavy’s rigid chassis; ideal for travel or training dives ≤100 m.   \n \n##### Versatility & Ergonomics  \n*\tCam bands accept varied cylinder diameters without shims.\n*\tBackplate geometry mirrors standard DIR harness so divers keep muscle memory in the water.\n\n<br>\n\n### 3. Liberty Sidemount – The Tight Passage Specialist or as a secondary rebreather\n**Ideal For**: Cave explorers, wreck penetrations, divers who prefer side mount cylinder distribution.\n##### Core Specs:\n*\t2l oxygen & diluent cylinders \n*\tRequires experience with multi-stage sidemount bailout\n*\tIdeal as a bailout rebreather to backmount or second sidemount unit\n*\t**Why It Excels:** \n> * Streamlined profile keeps the loop off the floor in silty restrictions\n> * Quick clip harness simplifies donning in small inflatables\n\n![Ginnie Springs, FL](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/58b56661af83bfc8d3577c391b816976d77303fe_divesoft-photo-050.jpg)  \n\n<br>\n\n\n### 4. Liberty DUAL (Liberty Backmout + Sidemount or Dual Sidemount) \n**Ideal For**: Record depth attempts, commercial bell standby, filmmakers who simply cannot surface.\n#####\tCore Specs:\n*\tTwo completely independent Liberty heads, loops & scrubbers\n*\tAutomatic master/slave handover on PO₂ deviation >0.2 bar for >30 s\n*\tWeight: 34 kg in dive trim (without cylinders)\n* **Why It Excels**:  \n> * Redundant loop in case of flooding the primary. \n> * True two double brains redundancy: each half can drive its own solenoid & HUD.\n> * Serves as self contained bail out – just one open circuit stage required for all depths.  \n\n<br>\n\n\n![Liberty Rebreather Diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/9afe8396b03aee84844313c2b9e75f8040ba83f0_divesoft-photo-179.jpg)  \n\n<br>\n\n## Configuration Tips for Depth & Duration\n**Cylinder Size & Positioning**\n*\t3 L steel diluent + 3 L O₂ covers 120 m descent with 20 min bottom and full CCR bail out margin.\n*\tPush deeper? Clip on 7 L off board diluent.\n \n**Work of Breathing & Counterlung Placement**\n\n*\tFront mounted counterlungs (FMCL) sit high on the chest, keeping differential hydrostatic pressure minimal and work of breathing (WOB) as low as 1.8 J/L at 100 m — this is why the original Liberty FML remains the benchmark for deep mix dives.\n*\tBack mounted counterlungs (BMCL) trade a slight WOB increase (~0.3 J/L higher in a 30° head up posture) for uncluttered chest D rings, crucial when you stage multiple bailout cylinders during deep descents.\n*\tChoosing FMCL vs BMCL: If your dive plan involves long penetrations with frequent bailout cylinder handling (typical on 150 m ocean drops), many teams pick BMCL for workspace. For maximal respiratory comfort on fixed rope vertical descents, FMCL wins.\n \n**Off Board Diluent Strategy (Critical for Cave Profiles)**\n\t\t\t\n*\tWhy it matters: Cave profiles surge through depth changes, forcing the loop to add gas constantly. An off board diluent stage prevents low volume warnings and keeps work of breathing down.\n*\tStandard setup: 7 L aluminium left clip with QC 6 quick connect hose feeding the diluent MAV.\n*\tAlternative (ADV manifold): Fit the [<span style=\"color:red\">Divesoft Off Board Manifold</span>](https://eshop.divesoft.com/off-board-manifold/8440) to the Automatic Diluent Valve – plug any off board bottle via QC 6 in seconds and swap or share gas under load.\n* Carry a second off board diluent (travel mix) for the shallow exit and as contingency for CO₂ breakthrough bailout.\n*\tDeco marathon? Off board your O₂ too: Plumb a QC 6 hose from the oxygen MAV so you can swap in a fresh high pressure O₂ bottle at the 6 m stop.\n> *\tConnector orientation best practice: “QC 6 on oxygen should be male on the rebreather side, the opposite of diluent, to make misconnections physically impossible,” notes   \n>** Tonda Ptáček**, elite Czech cave explorer.\n*\tDrill it: Practise feather drills and hose swaps so every teammate can donate or receive off board gas.\n\n<br>\n\n\n![Liberty Rebreather Diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/29d0135485d9a2b5e9b96e6c13ac98e0c04c2c90_divesoft-photo-180.jpg)  \n\n<br>\n\n\n## Bail Out CCR: Liberty SM as Redundant Life Support\nUsing a second Liberty Side Mount unit as bailout instead of stacking open circuit stages slashes drag and helium spend on >80 m dives. Liberty’s dedicated Bail out CCR firmware mirrors sensor status from the primary until activation, then runs fully independent once switched.  \nM

2aster this only after a specialised course. The world’s first Bail out Rebreather curriculum was written by Jakub Å imánek (author of this article) in 2023 and is now taught under TDI/RAID.  \n\n<br>\n\n## Conclusion – Choosing Your Life Support Partner\nDeep technical dives demand hardware that feels boringly reliable when everything else gets exciting. Liberty’s modular platform lets you pick the footprint (SM, Backmount, Heavy, or dual) that meets your risk envelope while keeping sensor voting, redundant electronics, and hot swappable batteries common across the line. Compare your mission profile against the tables above, and you’ll descend knowing your CCR is dialed long before you crack open the helium.\nReady to spec your unit?

Controlling the full value chain means we can guarantee:  \n* 100 % traceability of every component—from oxygen sensors to O rings.  \n* Redundant electronics philosophy: no single failure or even multiple failures can disable the life support loop.   \n * [CE & EN 14143 certification](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/docs/fbffa38fbe29542d87ed7a2dfe99e836397998b8_cw-pper-1-04-2025-module-beng.pdf) for temperatures 4 – 34 °C and depths to 100 m (Heliox 10/90).   \n\nOur factory was built from what was originally a carpenter's factory, which was in a desperate state. When the owners Aleš and Lucie bought the building in 2010 they carried out a thorough and costly renovation that turned a complete ruin into a modern, clean and functional world-class facility.  \n\nAles Procháska is a precise and technically minded person. His motivation was to create for himself and his speleo diving community a device that can work in all conditions and can be relied on not only on the way to the far ends of the cave, but especially on the way back. He has equipped the robust and cleverly thought-out design with a unique fully redundant control system that is fail-proof.  \n\nFor inclusion on the European market, but also as proof of Liberty's quality, we have undergone a CE certification process. Laboratory tests in ANSTI in the UK, Military Technical Institute in the Czech Republic and later in our own fully equipped laboratory prove that Liberty can be relied upon in all circumstances.

Rapid iteration lets us fail fast on land—not in the water.\n#### 2 | Material Sourcing & CNC Machining\n* Titanium & marine grade stainless steel are delivered with mill certificates.\n* Five axis CNC mills achieve tolerances to ±5 µm on the Liberty head and connectors and all other milled components.\n#### 3 | Electronics & Sensor Integration\nThe electronics are stress tested and their functionality is verified. [Oxygen sensors](https://eshop.divesoft.com/oxygen-sensor-divesoft-22d/3092) are batch checked in a proprietary pressure chamber that c

2orrelates each sensor’s mV output to partial pressure—allowing the Liberty to reject ‘lazy’ cells automatically.\n#### 4 | Assembly & Functional Testing\nA specially trained and experienced Divesoft technician assembles each unit from the ground up. Once the final quality control checks are completed, the technician passes the unit for final boxing, following a detailed 95-point checklist.  \n\nEach unit has its own station and as it grows, so do the entries in the assembly and service log. It's a kind of \"birth certificate\" of the unit.  \n\nThere is every component that is assembled into the device, its serial number and every operation that is performed with the unit is recorded. In the same way, all data is entered into the digital system. In this way, every operation and component that has ever been inserted into a particular unit can be traced back perfectly.\n\n![Divesoft Factory](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/2baf34d59e1eebdc16a642e3d8a7eac9b343a522_divesoft-photo-253.jpg)\n\n________________________________________\n## Quality Control & Testing Protocols\n#### Depth Simulations on Big Bertha\nLiberty spent countless hours on ‘Iron Man’ inside Big Bertha, a custom pressure chamber capable of simulating 300 m dives. Design of all the components, work of breathing, the sensors, solenoid timings and PPO₂ controls were logged at 50 Hz so anomalies could be spotted long before the design was finalized and the unit reached its final state.  \n\n#### Redundancy Checks\nTwo complete, isolated control boards run in parallel. During testing we force fail each board; the surviving board must maintain loop control within ±0.05 bar. If it can’t, the unit is quarantined for root cause analysis.\n\n![Divesoft Factory](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c25cca5c019e9caac18c8bcddc945964e6f2ca04_divesoft-photo-251.jpg)\n\n________________________________________\n\n<br>\n\n<div style=\"margin:10px 0; overflow-y: scroll; background:; padding: 10px\">\n  <table style=\"min-width: 700px\">\n    <tr>\n      <td style=\"padding: 10px\" colspan=\"3\">\n        <h3>Meet the People Behind Liberty CCRs</h3>\n      </td>\n    </tr>\n    <tr style=\"border-bottom: 2px solid gray;\">\n      <th style=\"padding:10px;\">Name</th>\n      <th style=\"padding:10px;\">Role</th>\n      <th style=\"padding:10px;\">Quote</th>\n    </tr>\n    <tr style=\"border-bottom: 1px solid gray;\">\n      <th style=\"padding:10px;\">AleÅ¡ Procháska</th>\n      <td style=\"padding:10px;\">Co founder & CTO</td>\n      <td style=\"padding:10px;\">“If we can’t measure it, we redesign until we can.” < 2.4 J/L @ 100 m.v</td>\n    </tr>\n    <tr style=\"border-bottom: 1px solid gray;\">\n      <th style=\"padding:10px;\">Ondřej Zouna</th>\n      <td style=\"padding:10px;\">Chief fitter</td>\n      <td style=\"padding:10px;\">“I treat every head like it’s going on my own back.”</td>\n    </tr>\n    <tr style=\"border-bottom: 1px solid gray;\">\n      <th style=\"padding:10px;\">Martin TopÅ¡</th>\n      <td style=\"padding:10px;\">Designer</td>\n      <td style=\"padding:10px;\">“Redundancy is great, but knowing why a component failed is better.”</td>  \n\t\t\t   </tr>\n    <tr style=\"border-bottom: 1px solid gray;\">\n      <th style=\"padding:10px;\">Jakub Å imánek</th>\n      <td style=\"padding:10px;\">Factory Trainer</td>\n      <td style=\"padding:10px;\">“My favourite sound is no bubbles at 90 m.”</td>  \n\n\n\t\t\t\n<br>\n\nName\tRole\tQuote\nAleÅ¡ Procháska\tCo founder & CTO\t“If we can’t measure it, we redesign until we can.”\nOndřej Zouna\tChief fitter\t“I treat every head like it’s going on my own back.”\nMartin TopÅ¡\tDesigner\t“Redundancy is great, but knowing why a component failed is better.”\nJakub Å imánek\tFactory Trainer\t“My favourite sound is no bubbles at 90 m.”\n________________________________________\n## How Our Philosophy Shapes the Product\n#### Safety First\nDual independent power supplies and full sensor voting keep you breathing even in the case of multiple failures.  \n\n#### Modularity  \n* Backmount or sidemount conversions use the same core electronics—future proofing your investment.\nRelentless Innovation  \n* Recent firmware updates have introduced Closed Cylinder Detection, an integrated splash checklist accessible directly on the handset, and the unique bailout CCR mode, among a range of other hardware and software innovations.\n\n#### Real Diver Feedback Loops\nWe work with a large community of test divers.

As you inhale, you’ll float up a bit; as you exhale, you’ll drift down. You’ve been balancing your buoyancy this way since your first Open Water course, and by now you’re really good at it—you can hover in place as if nailed to the seabed. But what if someone took away that locomotive and plunked you into a Shinkansen? That’s exactly the feeling I had on my very first dive with a CCR (Closed Circuit Rebreather).","content":"\n\n## Time to Take the Plunge… But How?\nMy first encounter with a CCR was anything but ordinary. At that time, I was already a technical diving instructor and had been studying CCRs with great enthusiasm for a long time. It happened shortly after I began working for DIVESOFT. The Liberty was still a functional prototype awaiting its first CE certification, and I was prepping it for testing.\n\n## An Anchor Hunt, CCR-Style  \nOur in-house programmer, nicknamed “Termit” (a tireless workhorse and coding elder statesman), owns a boat on the Orlík reservoir. He managed to lose his anchor somewhere in the middle of a cove and asked me for help retrieving it. Of course, we leapt at the chance! AleÅ¡ Procháska suggested we do the job on rebreathers—and I was thrilled… but diving my CCR for the first time while hunting for a lost anchor?\n\n## Assembling the Prototype: First Impressions  \nI set up the unit almost entirely on my own—I knew it inside out. This prototype differed from today’s production Liberty units in several key ways: it featured a front-mounted counterlung (FMCL) instead of the now-common back-mounted style; its electronics ran on two sets of six AA batteries that had to be swapped after every dive; the Automatic Diluent Valve (ADV) sat at the bottom of the counterlung and was completely different in design; and both inhale and exhale counterlungs had large overpressure relief valves. Many solutions were awaiting final tweaks, so prepping the prototype wasn’t without its challenges.\

2n\n## Suiting Up and Diving In  \nAleÅ¡ coached me through a final checklist, and then I donned the rig. My first impression wasn’t great—two bulky counterlungs on my chest and a thick corrugated hose whipping around made me feel clumsy, and the sun beat down mercilessly. But the moment we slipped beneath the surface, all awkwardness vanished. My senses snapped to attention: my eyes darted side to side, my ears strained for silence, and my fingers hovered over the inflator, ready to perform the subtle lung-compensating work I’d spent years perfecting.\n\n## Expectations vs. Reality Underwater  \nI anticipated the hot blast of air from the scrubber, but at first I couldn’t distinguish it. I expected total silence, yet when I focused closely, the sounds reminded me of breathing through a snorkel. The whirr of the solenoid was barely audible—and in shallow water, it threw me off balance when it injected oxygen just after I’d achieved perfect trim.\n\n## The Dive: Crystal Clarity and Quick Recovery  \nIt’s been ages, but I still remember that sunlit, golden water—unusually clear for this spot. We found the anchor quickly, around 22 meters down. I was amazed by the razor-sharp displays on our handheld units, glowing like twin jewels in the dusky depths, clearly showing every vital reading.\n\n## The Ascent Surprise: Mastering Buoyancy Again  \nSurfacing was my biggest shock. I’d anticipated the different buoyancy, the silence, and all the other CCR quirks—but I wasn’t prepared for the pressure in my lungs during ascent. On open-circuit, you simply breathe out and let the excess gas escape. Here, I learned fast that I had to actively purge gas outside the loop or crack the overpressure valves.\n\nI emerged utterly exhilarated.

As you inhale, you’ll float up a bit; as you exhale, you’ll drift down. You’ve been balancing your buoyancy this way since your first Open Water course, and by now you’re really good at it—you can hover in place as if nailed to the seabed. But what if someone took away that locomotive and plunked you into a Shinkansen? That’s exactly the feeling I had on my very first dive with a [CCR (Closed Circuit Rebreather)](https://www.divesoft.com/en/products/ccr-liberty).","content":"## Time to Take the Plunge… But How?  \nMy first encounter with a CCR was anything but ordinary. At that time, I was already a technical diving instructor and had been studying CCRs with great enthusiasm for a long time. It happened shortly after I began working for [DIVESOFT](https://www.divesoft.com/). The Liberty was still a functional prototype awaiting its first CE certification, and I was prepping it for testing.\n\n![Jakub Å imánek](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/f6d8546c95140e38b01937728586f1ede0608aae_divesoft-photo-060.jpg)\n\n## An Anchor Hunt, CCR-Style  \nOur in-house programmer, nicknamed “Termit” (a tireless workhorse and coding elder statesman), owns a boat on the Orlík reservoir. He managed to lose his anchor somewhere in the middle of a cove and asked me for help retrieving it. Of course, we leapt at the chance! AleÅ¡ Procháska suggested we do the job on rebreathers—and I was thrilled… but diving my CCR for the first time while hunting for a lost anchor?\n\n## Assembling the Prototype: First Impressions  \nI set up the unit almost entirely on my own—I knew it inside out. This prototype differed from today’s production Liberty units in several key ways: it featured a front-mounted counterlung ([FMCL](https://www.divesoft.com/en/products/ccr-liberty/ccr-liberty-bmcl-fmcl)) instead of the now-common back-mounted style; its electronics ran on two sets of six AA batteries that had to be swapped after every dive; the Automatic Diluent Valve ([ADV](https://www.divesoft.com/en/products/bovdsvadv)) sat at the bottom of the counterlung and was completely different in design; and both inhale and exhale counterlungs had large overpressure relief valves. Many solutions were awaiting final tweaks, so prepping the prototype wasn’t without its challenges.\

My first impression wasn’t great—two bulky counterlungs on my chest and a thick corrugated hose whipping around made me feel clumsy, and the sun beat down mercilessly. But the moment we slipped beneath the surface, all awkwardness vanished. My senses snapped to attention: my eyes darted side to side, my ears strained for silence, and my fingers hovered over the inflator, ready to perform the subtle lung-compensating work I’d spent years perfecting.\n\n## Expectations vs. Reality Underwater  \nI anticipated the hot blast of air from the scrubber, but at first I couldn’t distinguish it. I expected total silence, yet when I focused closely, the sounds reminded me of breathing through a snorkel. The whirr of the solenoid was barely audible—and in shallow water, it threw me off balance when it injected oxygen just after I’d achieved perfect trim.\n\n![Jakub Šimánek](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/89ae96a7f1708589fffb555337b4f982fba705b1_divesoft-photo-074.jpg)\n\n## The Dive: Crystal Clarity and Quick Recovery  \nIt’s been ages, but I still remember that sunlit, golden water—unusually clear for this spot. We found the anchor quickly, around 22 meters down. I was amazed by the razor-sharp displays on our handheld units, glowing like twin jewels in the dusky depths, clearly showing every vital reading.\n\n## The Ascent Surprise: Mastering Buoyancy Again  \nSurfacing was my biggest shock. I’d anticipated the different buoyancy, the silence, and all the other CCR quirks—but I wasn’t prepared for the pressure in my lungs during ascent. On open-circuit, you simply breathe out and let the excess gas escape. Here, I learned fast that I had to actively purge gas outside the loop or crack the overpressure valves.\n\nI emerged utterly exhilarated. I wished Aleš didn’t have to rush home—I could have floated there until the scrubber ran dry. In the years that followed, however, I more than made up for it.\n\n## From Student to Mentor: A CCR Journey  \nSince then, I’ve logged hundreds—if not thousands—of hours on the Liberty, and I’ve guided countless divers, instructors, and instructor-trainers into the CCR world.

It was during a demo event held occasionally by one of the local dive centers. At the time, I wasn’t sure if rebreather diving was the right path for me—I thought OC trimix was probably the highest level I’d ever go. Still, I was curious to experience it firsthand. Since the dive center was offering try-dives with rebreathers, I figured—why not? Why not try something different?\nAt the event, there were two different units available. I had the chance to try both in a pool after a quick introduction to how they functioned. Before that day, I had always thought of rebreathers as extremely complicated, overly sophisticated, and difficult to understand. But once I saw the units in person, I realized they weren’t nearly as intimidating as I had imagined.","content":"![Jakub Sláma](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/8f2634cb41622d3a63ccaf1ff10b74d1386ff8a3_divesoft-photo-029.jpg)\n\n## Very Different Than Expected  \nThat first pool session was eye-opening. The pool was around 3 meters deep, and I started off kneeling on the bottom before experimenting with my buoyancy. I just looked up and relaxed. The first thing I noticed was the silence. It struck me immediately. That silence was the very first sensation I remember from diving on a rebreather. Suddenly, my perception of the underwater world shifted I hadn’t realized just how loud open circuit actually was. From that moment on, I always noticed the noise of OC diving.\nThat also explained why my underwater photos often had fish tails in them—once the fish heard me, they’d swim away. Now that I dive mostly with a rebreather, especially as an underwater photographer, the fish come to me. When you’re on a rebreather, you can hear OC divers approaching from far away. That contrast—between silence and noise—was one of the key sensations I remember from that first try-dive.\nThe next thing I noticed was buoyancy control. At the time, I already had several hundred OC dives under my belt, and I’d often heard that the better you are on OC, the harder it is to adapt to a rebreather. But during that first dive, buoyancy felt surprisingly natural. I didn’t fully understand what the handset was showing me—PPO2 readings of sensors were not as familiar as they are now—but that didn’t matter at the time. What mattered was how I experienced the underwater world.\n\n![Jakub Sláma](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/fc7063dae59e65fc699b07c4e9c8c2e49abaf47a_divesoft-photo-114.jpg)\n\n## An Experience That Changes Everything  \nWe go diving to absorb the underwater world, and I immediately recognized how much better a rebreather allowed me to do just that. It was the beginning of what I now think of as truly “ZEN” underwater moments. Diving became an escape—no phones, no stress, a quiet exploration in weightlessness. It opened up a whole new dimension.\n\n![Jakub Sláma](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/6d6681e5b7f87bf9e1de2d46f591edc106efd511_divesoft-photo-25.jpg)\n\n## The Initial Experience Down the Line  \nLater on, I came to appreciate the practical benefits of rebreathers too: dramatically extended dive times, warmer breathing gas that kept me comfortable on longer dives, the silence, and simpler gas logistics with 

2no underwater gas switching. These were just bonuses on top of the transformative experience.\nEventually, I found myself enjoying the entire process of rebreather diving—from prepping the unit to being part of the rebreather community, exchanging experiences, and reaching sites most divers never get to see. The rebreather extended my range and gave me access to truly rare underwater locations.\nI would absolutely recommend that anyone try a rebreather at least once, even if you don’t plan to get one. The experience itself—how different it feels—is well worth it. Try it and see where it takes you.\n\nAuthor: Jakub Sláma","showTags":false,"showDate":false},"id":"#3","type":"component","lock":false,"position":2},{"name":"Image","data":{"firstImage":{"recommendedSizes":{"width":"1000","height":"1000"}},"secondImage":{"recommendedSizes":{"width":"1000","height":"1000"}}},"id":"#7","type":"component","lock":false,"position":3},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#6","type":"component","lock":false,"position":4},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":7}],"id":"root","idBuffer":"#8","lastCommit":"4fdbf2e6-4206-4392-96b9-2b7199ce73b2"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cm9cmcoo1fcrp0803vl5desvj":{"id":"cm9cmcoo1fcrp0803vl5desvj","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[{"type":"id","generated":false,"id":"Tag:cjv3szrcv01bz0836yo8myb0r","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww05zc1b5d0803zglvz927","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cmfp50qhi00lk08324ek37f9g","typename":"Tag"}],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cm9cmcoojfcrw0803dsui6xh9","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cm9cmcoojfcrw0803dsui6xh9":{"id":"cm9cmcoojfcrw0803dsui6xh9","name":"CCR safety rules and procedures","createdAt":"2025-04-11T10:03:08.658Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

With the right mindset and an instructor who refuses to cut corners, anyone can master these checks and enjoy safer, more rewarding dives.","content":"### 1. Pre-Dive Preparation  \nA rigorous pre-dive preparation process is non-negotiable. Whether you use a paper checklist or, as many [Liberty CCR](https://www.divesoft.com/en/products/ccr-liberty) owners do, the [Divesoft.App](https://www.divesoft.com/en/app) on your smartphone, step through every assembly and function test systematically. The Divesoft.App not only guides you through each valve, sensor calibration and line routing with photos and descriptions, but it even calculates expected voltages for your oxygen cells—flagging anomalies before you submerge. Crucially, it enforces a positive- and negative-pressure leak test to verify loop-integrity: flooding a CCR underwater is irreparable and forces an immediate bailout.\n\n**“We may be able to prevent as many as 90 % of fatal rebreather accidents by merely using and adhering to a checklist and doing it for every dive.**”  \n— Jill Heinerth, Rebreather Training Council: “[Why and how do you use checklists?](https://rebreathertrainingcouncil.org/safety-initiatives/checklists/why-use-checklists/jill-heinerth-2/)”\n\n![Jakub Slama](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/85994740161003539ddb838a8690b120f320e6f5_divesoft-photo-026.jpg)\n\n### 2. Splash-Entry Checklist\nJust before entering the water, perform a splash-entry check. On [Liberty CCR](https://www.divesoft.com/en/products/ccr-liberty)s this is built into the unit’s software: verify cylinder valves are fully open, setpoints displayed correctly, the ADV, MAV and BOV are functioning, and your bailout system is armed. Back-mounted units allow you to cycle through this on your wrist-mounted console; side-mount setups typically have the checklist in front of you on a tablet or slate. This step ensures all vital systems are “go” before gravity takes over.\n\n![Rebreather divers](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/43a578fa69b84a210251ac72188b3b540ebe391a_divesoft-photo-230.jpg)\n\n### 3. Pre-Breathing Sequence  \nA five-minute pre-breathing on the loop remains standard to confirm oxygen injection and loop integrity. However, relying on it to validate scrubber performance is misleading. In a randomized, single-blind study led by Dr. Simon Mitchell, 90 percent of divers failed to detect a partially failed or absent CO₂ absorbent during a five-minute prebreathe—highlighting its insensitivity to real scrubber faults.  \nUse prebreathe to check work-of-breathing, PO₂ response, and loop-comfort—but never as proof of a correctly packed or effective scrubber.\n\nThe primary study is:\n\nDeng C, Pollock NW, Gant N, Hannam JA, Dooley A, Mesley P, Mitchell SJ.\n“The five-minute prebreathe in evaluating carbon dioxide absorption in a closed-circuit rebreather: a randomised

Here just a short characeristics\n\n**Avoid Complacency  **  \nEven a perfectly functioning CCR can lull you into autopilot. Maintain constant vigilance—skip nothing.\n\n**1. Avoid Distraction**  \nKeep your focus on the dive; minor interruptions can cascade into major errors.\n\n**2. Be a Disciplined Diver**  \nFollow procedures consistently, even when conditions are calm.\n\n**3. Be a Thinking Diver**  \nContinually assess and adapt; don’t rely solely on routine.\n\n**4. Always Know Your PO₂**  \nMonitor your partial pressure of oxygen frequently—both high and low extremes are life-threatening.\n\n**5. Don’t Be Cheap**  \nDon't skimp on sensors, sorbent or helium. Don't prolong their lifespan just to save money and lose a life.\n\n**6. CCR Is Your Primary SCUBA**  \nYou have CCR, so dive with CCR even where it's not absolutely necessary. If you don't dive with it regularly, you'll lose the habits you've learned.\n\n**7. Practice Bailout Periodically **   \nRehearse switching to open-circuit bailout until it becomes reflexive. Practice other life-saving scenarios.\n\n**8. Assume Devices Will Fail**  \nDesign your dive plan around redundancy and conservative bailouts. \n\n**9. Accept That Emergencies Will Happen**  \nMental rehearsal of worst-case scenarios sharpens your response under stress.\n\n**10. Do Not Start with Known Failure**  \nIf any component fails a pre-dive or in-water check, stand down and resolve it.\n\n\n![Rebreather divers](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/bc1ef5d15e01f1907c173cadcee0d21c68b30659_divesoft-photo-173.jpg)\n\n### Choosing the Right Instructor  \nNone of these procedures matter without solid instruction. Seek an instructor who:\n\n* **Emphasizes Theory & Practice:** You should fully understand gas dynamics, sensor operation and failure modes before your first open-water dive.\n* **Insists on Checklists:** Every step must be done in order, every time—no shortcuts.\n* **Fosters Critical Thinking:** Training scenarios should include simulated failures to build decision-making skills under pressure.\n* **Protects No-Go Zones:** Depth and decompression limits must be conservative; your instructor should never rush you.\n\nWith careful preparation, systematic checks and a vigilant mindset, CCR diving is no more difficult than mastering any advanced technical skill—it just demands respect for its complexity. By following these rules and choosing a rigorous instructor, you’ll unlock the silent, extended dives CCRs promise while keeping every excursion safe and enjoyable.\n\n\n________________________________________\n\nAuthor: [Jakub Å imánek](https://www.divesoft.com/en/about-us/jakub-simanek)","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":1086367,"hash":"cba11723cb878f2cbd1a46df01a8ad414edff1ea","id":"cmdrb2iwo0ppj0850drnxxfz6","filename":"divesoft-photo-167-0.jpg","category":"divesoft/","type":"image"},"publishDate":"08/05/2025"},"id":"#2","type":"component","lock":false,"position":2},{"name":"ProductShowcase","data":{"backgroundColor":"#ffffff","isTextDark":true,"isImageRight":false,"image":{"recommendedSizes":{"width":"485","height":"485"},"mimetype":"image/png","size":1301657,"hash":"43e9e651a9f52d00f08256ebeafeddc32164c11f","id":"cm737a5egjeyt08505ycj0rdm","filename":"divesoft-app-202502-01.png","category":"divesoft/","type":"image"},"imageMobile":{"recommendedSizes":{"width":"510","height":"510"}},"isTitleH1":false,"title":"Divesoft.app","subtitle":"Plan your decompression, gasses, utilize checklists, check your logs + more.","description":"All for Free.","hideDescriptionOnMobile":false,"areButtons":false,"firstTitle":"Learn more >","firstUrl":{"url":"/en/app","pageId":"ckfccnc4a98bx0788f7enal83"},"secondTitle":"Configurator >","secondUrl":""},"id":"#21","type":"component","lock":false,"position":4},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/@divesoft_tv","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]","twitterUrl":{"url":"","urlNewWindow":true,"pageId":"cjv3l26tp004p0836i54n4u7a"}},"id":"#1","type":"component","lock":false,"position":5}

Even if you have years of open-circuit experience, much of what you’ve learned will only partially transfer. Instead, you’ll face an array of new skills, concepts, and procedures. To take this step, you already need to be comfortable in the water: navigating, moving with control, managing buoyancy, and calmly handling basic emergencies. Being “at home” underwater is essential, because CCR training will demand your full focus on the new challenges rebreathers bring.","content":"![Rebreather course](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/6b8620e5812346f54bb4c2e250a2fd3842a649ad_divesoft-photo-031.jpg)\n\n### The Theory: Building a New Foundation\n\nBefore you enter the water with a CCR, you spend significant time in the classroom. The theoretical part of the training covers the principles and science behind the equipment:\n\n* **CCR systems**: Understanding how closed and semi-closed circuits work.\n* **Construction and components**: What makes up a rebreather, and the function of each part.\n* **Physics**: Critical for grasping how CCR behaves differently from open circuit.\n* **Physiology**: Oxygen and CO₂ management, gas density, human limits, decompression.\n* **Chemistry**: How scrubbers work and why CO₂ absorption matters.\n* **Electronics and controls**: Familiarity with the unit’s displays, alarms, and logic.\n* **Dive planning with CCR**: Dealing with bailout strategies, runtime limits, and contingencies.\n\nThis background knowledge is vital. You are not just learning how to use a new piece of kit—you’re learning how to understand and trust the machine that will sustain your breathing in places where surfacing is not an option.\n\n![Rebreather course](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/f6d8546c95140e38b01937728586f1ede0608aae_divesoft-photo-060.jpg)\n\n### The Practice: From Dry Runs to Real Dives\n\nOnce the theory is in place, training moves into practice.\n\n* **Dry preparation**: Assembly, disassembly, maintenance, and using [checklists](https://www.divesoft.com/en/app) for pre-dive tests.\n* **Confined water sessions**: Initial dives in a pool or sheltered water.\n* **Open-water dives**: Progressing to controlled environments and eventually real diving scenarios.\n* **Skills development**:\n1. Entries and ascents with a CCR  \n1. Mastering buoyancy in a new way (counterlungs change everything)  \n1. Monitoring and adjusting PO₂  \n1. Manual control of PO₂  \n1. Exercises to internalize CCR principles  \n1. Emergency responses—hypoxia, hyperoxia, hypercapnia, floods, electronics failures\n\nEmergency drills make up a large part of [CCR training](https://www.divesoft.com/en/instructors). Different agencies teach multiple approaches—sometimes in parallel, sometimes tailored to their philosophy. Manufacturers also influence training: for the Liberty CCR, Divesoft appointed Jakub Šimánek to define unit-specific training standards. Over the years, he has prepared dozens of instructors and instructor-trainers, shaping consistent practices around this unit.\n\n![Rebreather course](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/e2e47795cbcf77

2dab89da30c8f99e0aab45cb61c_divesoft-photo-155.jpg)\n\n### Why Training Matters\n\nExperienced rebreather divers often emphasize that solid training is what allows you to safely unlock the potential of a CCR. These perspectives align with what training agencies and the Rebreather Training Council (RTC) stress: CCR diving is a discipline of precision, redundancy, and planning. The unit itself may be robust—“Liberty is certified to the highest international standards, which is a peace of mind for technical divers”—but it’s the diver’s preparation that makes the difference.\n\n![Rebreather course](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/73b9146a1bb5083a2ff0a52a1cb7d42e0f6d7174_divesoft-photo-218.jpg)\n\n### What to Expect as a Student\n\nExpect to feel like a beginner again. You’ll spend long hours repeating drills, sometimes until they feel automatic. You’ll analyze problems, solve them, and then solve them again in different ways. You’ll learn to slow down, think ahead, and make decisions based on gas management, PO₂ monitoring, and unit behavior.\n\nThe process can be humbling—but it’s also rewarding. By the end of the course, you won’t just know how to dive a CCR. You’ll understand the why behind every procedure, and you’ll have the confidence to handle the unexpected.\n\n![Rebreather course](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/919e170df0f7f5629d963da0b977b526c53073fc_divesoft-photo-225.jpg)\n\n### A Gateway to Exploration\n\nWhen training is complete, a CCR opens doors to dives that were once beyond reach—longer bottom times, quieter encounters with marine life, and the ability to explore caves and wrecks with a different margin of safety. As one review put it, “For deep technical and exploration, [Liberty CCR](https://www.divesoft.com/en/products/ccr-liberty) is among the most robust and configurable”.\n\nBut reaching that point begins with training: structured, demanding, and transformative. If you’re ready to start, prepare to relearn diving from the ground up.\n\n[The previous article](https://www.divesoft.com/en/blog/what-is-a-rebreather-do-i-need-one-as-a-recreational-diver) can help you with that.  \n\n* [Jakub Å imánek](https://www.divesoft.com/en/about-us/jakub-simanek), Divesoft Factory IT\n","showTags":false,"showDate":false,"image":{"mimetype":"image/jpeg","size":800870,"hash":"d8d11a4b6426c0dd3c2e61f61df67d211e10e7df","id":"cmeijmu0ia56a0850wj5p5erl","filename":"divesoft-photo-159-1.jpg","category":"divesoft/","type":"image","alt":"Rebreather diver, Adam Prochaska"}},"id":"#3","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#7","type":"component","lock":false,"position":3},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/channel/UCHI2-kHmfoUlAdhQXPKl8lA/featured","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":5}],"id":"root","idBuffer":"#10","lastCommit":"9deed358-2481-4040-b2af-d79b12ddac8c"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cm9cmdlxcfcsp0803p0d518jj":{"id":"cm9cmdlxcfcsp0803p0d518jj","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[{"type":"id","generated":false,"id":"Tag:cjv3szrcv01bz0836yo8myb0r","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww05zc1b5d0803zglvz927","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cmfp50qhi00lk08324ek37f9g","typename":"Tag"}],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cm9cmdlxrfcsw08036zlor12o","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cm9cmdlxrfcsw08036zlor12o":{"id":"cm9cmdlxrfcsw08036zlor12o","name":"Most common diving mistakes: this could save your life!","createdAt":"2025-04-11T10:03:51.759Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

Yet beneath the surface, danger always lurks. Decades of accident reports consistently reveal one uncomfortable truth: most diving accidents are caused by human error. In fact, between 60–80% of all diving incidents could have been prevented with better preparation, decision-making, or awareness.\n\nThis article summarizes key findings from recent studies and highlights the most common mistakes divers make – and how you can avoid them.","content":"## How often is human error to blame?\nSeveral independent reports agree: human mistakes dominate as the root cause of diving incidents.\n\nA comprehensive review of 185 fatal accidents involving Czech and Slovak divers (1965–2025) found that the overwhelming majority were caused by poor decisions, inadequate preparation, or ignoring personal health. Only a very small percentage were due to pure equipment failure ([Hovorka & Belica, 2025, Smrtelné nehody českých a slovenských potápěčů](https://swarm.craa.cz/wp-content/uploads/2025/08/Smrtelne-nehody-ceskych-a-slovenskych-potapecu-1965-2025.pdf)\n).\n\nThe British Sub-Aqua Club Annual Diving Incident Report 2023 recorded 355 incidents (113 overseas), with human error present in more than 70% of cases. Fatalities were most often linked to rapid ascents, poor gas planning, or panic underwater ([BSAC, 2023](https://www.bsac.com/document/bsac-diving-incidents-report-2023/1bsac-diving-incident-report-2023.pdf\n).\n\nGlobally, the Divers Alert Network (DAN) Annual Diving Report has repeatedly shown that around 80% of both fatal and non-fatal incidents include human error as a primary or contributing factor ([DAN Annual Diving Reports](https://dan.org/research-reports/publication-library/?utm_source=chatgpt.com)\n).\n\n## The most common mistakes that cost lives\n#### 1. Poor planning and decision-making\n\nMany accidents begin before the diver even enters the water. Choosing a site beyond one’s training, ignoring weather or current conditions, or planning dives that exceed safe depth or gas reserves are recurring patterns.\n\n#### 2. Inadequate equipment checks\n\nSimple oversights – forgetting to open a tank valve, skipping the buddy check, or diving with poorly maintained gear – are frequent triggers of emergencies that could have been easily prevented.\n\n#### 3. Panic and poor problem-solving underwater\n\nWhen something goes wrong, panic can turn a minor issue into a fatal one. Studies show that divers often fail to apply their training in stressful situations, leading to uncontrolled ascents, out-of-air situations, or drowning.\n\n#### 4. Ignoring health and fitness\n\nUnderlying health conditions – especially cardiac problems, obesity, or poor physical fitness – are a common factor in fatal diving accidents. In many cases, divers underestimated their limitations or continued diving despite clear medical contraindications.\n\n## What this means for divers\n\nThe message from all these reports is clear: diving is not inherently dangerous, but divers can make it dangerous. By recognizing how often human error leads to tragedy, every diver can take steps to reduce their personal risk:\n\nRespect your training limits and gain experience gradually.\n\nNever skip equipment checks and buddy procedures.\n\nPractice emergency drills until they become automatic.\n\nTake health and fitness seriously – your body is your life support system.\n\n## Final thoughts\n\nWhile diving equipment continues to evolve and become more reliable, the greatest safety improvement lies in human behavior. Paying attention to these lessons, learned through hundreds of accidents, could literally save your life.\n\nStay safe, dive smart, and remember: prevention is always easier than rescue.\n\n![Jakub Šimánek](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/04858315661f20be66bd9081f6aa87c258732ca3_foto-clanek-mistakes-2.jpg)\n\n\nAuthor: [Jakub Šimánek](https://www.divesoft.com/en/about-us/jakub-simanek)\n\n“Images featured in this blog are for illustrative purposes only and may not represent the actual products, services, or situations described.”","showTags":false,"showDate":true,"publishDate":"09/01/2025","image":{"mimetype":"image/jpeg","size":1800183,"hash":"0e806cece324b6f63990e77400812175747fa4ba","id":"cmf18imuifnwz08504trr0ja7","filename":"foto-clanek-mistakes-1.jpg","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

In today’s article, we will **focus specifically and practically on planning a closed-circuit rebreather (CCR) dive for beginners.**\n\n","content":"> “After my first 10 hours on a rebreather, I was a real expert. Another 40 hours of dive time later, I considered myself a novice. When I completed about 100 hours of rebreather diving, I realized I was only just a beginner.”   \n> — **Richard Pyle**, reflecting on the steep learning curve of rebreather diving [blog.padi.com](https://blog.padi.com/tec-dossier-jonas-samuelsson/#:~:text=Open,%E2%80%9D)\n\n![Rebreather diver](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/c31a11b0ab59b4f733f46f8823ad8ba92870ca7a_dsc-1609-2-enhanced-nr-full.jpg)\n\nWhen diving, everything is interconnected, and the plan must form a coherent whole. It is therefore essential to establish a clear starting point. Naturally, the starting values are depth and bottom time. We generally dive to different depths for varying lengths of time. While we usually have a clear idea of the intended depth, determining bottom time is not always simple, as it is often limited by available gas supply and the required decompression obligation. Sometimes we must use the method of halving the interval, choosing a bottom time that fits within our gas reserves. When we talk about gas supply in closed-circuit diving, we mostly mean bailout gas. Especially for beginners, it is not assumed that dives will be carried out at the limits of rebreather gas capacity. The simplest scenario, of course, is when we have a very specific bottom time required to achieve our goal.\n\n\n### Starting Point – Depth and Time\n\nTo make things clearer, let’s plan a wreck dive. This is simple because wreck dives usually begin from a boat, descending down a line directly to the target depth. Time is then spent at roughly the same depth, give or take a few meters (unless it’s a very large wreck). Let’s assume this wreck lies at 35 meters. I chose this depth deliberately, as I consider it the maximum for air diluent CCR diving.\n\nHow long do we need to spend at the wreck? Suppose the wreck is 50 meters long. The typical swimming speed of a technical diver ranges from 10 to 15 meters per minute. Since we’re not racing but rather observing and exploring, we’ll choose a more conservative value—5 meters per minute. To swim around the 50-meter wreck, that gives us about 20 minutes.\n\n\n### Choosing the Setpoint\

2n\nTo plan decompression, we must first decide on the setpoint—the partial pressure of oxygen during the CCR dive. Looking at CNS exposure tables, we find that at a PO2 of 1.3\n\nbar, the maximum exposure is 180 minutes. This is more than enough for our purposes. A higher constant PO2 would not be safe. Lower setpoints are used for dives deeper than 50 m or under demanding conditions (currents, cold water, heavy workload).\n\nFor descent, we use a lower setpoint, as high PO2 is unsuitable at the surface and would rise dangerously during descent. A common descent setpoint is 0.7 bar. With the [Liberty CCR](https://www.divesoft.com/en/products/ccr-liberty), we can also set a “descent setpoint” that increases proportionally with depth, saving oxygen. For example, this could be set at 0.4 bar.\n\n### Gas Selection\n\nIn this example, we will use air as the diluent, since the article is aimed at beginners. Nitrox is not suitable as a diluent because it would exceed our planned setpoint. However, nitrox is better suited as bailout gas. At the planned maximum depth of 35 m, the pressure is 4.5 bar. At a maximum PO2 of 1.6 bar for the bailout cylinder, this gives us nitrox 35 (1.6 / 4.5 = 0.35). We will use the standard nitrox 32.\n\n\n### Ascent Planning\n\nWe now know enough to plan ascent and decompression. The best tool is a decompression planner. A good choice is divesoft.app, which provides advanced CCR dive planning. Using gradient factors 40/75 (a conservative and safe setting), the result is a single stop at 6 m for 2 minutes (with ascent speed of 9 m/min).\n\n\n### Gas Management\n\nGas planning for this dive is straightforward. Diluent is calculated by multiplying depth pressure and loop volume, then conservatively by 2.5. In our case: 4.5 bar × 10 liters × 2.5 = 112.5 liters. In a 3-liter cylinder, that is 37.5 bar. We also know dives should not begin with less than 100 bar.\n\nOxygen is even simpler. Total dive time is 27 minutes. At a conservative consumption of 2 liters/min, that equals 54 liters, or 18 bar in a 3-liter cylinder.\n\n\n### Scrubber Duration\n\nWe must also consider scrubber duration. The minimum duration is 2 hours 47 minutes, even under heavy workload and cold water. Our 27-minute dive is well within this.\n\n\n### Plan B – The “Shit Plan”\n\nThe most important aspect of CCR planning is preparing for emergencies where the unit cannot be used to ascend. This could be a flooded unit or (although unlikely with Liberty) a total electronics failure.\n\nAt any point, we must be able to ascend on open circuit. We need sufficient bailout gas to cover the remaining bottom time plus a safety margin (usually 3 minutes), with breathing rates elevated due to stress—often 50 liters/min. Hypercapnia, very relevant in CCR diving, must be considered.\n\nOn open circuit, PO2 will decrease during ascent, so decompression will be less efficient than with CCR. Adding 3 minutes bottom time and switching to open circuit extends decompression to a 1-minute stop at 9 m and 9 minutes at 6 m.\n\nCalculating gas use for this profile: 2076 liters of nitrox 32 are required. In a 12-liter cylinder, that is 173 bar; in an AL80, it is 187 bar.\n\n\n### Conclusion\n\nThis example shows that even a relatively short, simple dive can become bailout-gas-limited in an emergency. If air were used instead of nitrox, gas supply would not suffice. Always plan dives carefully to avoid unpleasant or dangerous situations\n\nAuthor: [Jakub Šimánek](https://www.divesoft.com/en/about-us/jakub-simanek)\n","showTags":false,"showDate":true,"publishDate":"09/26/2025","image":{"mimetype":"image/jpeg","size":3591367,"hash":"74a7474b18a92a2baef49c5016766117af8bb0a4","id":"cmg0q69meqyub08506ue6gu50","filename":"dsc00263-160.jpg","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"Image","data":{"firstImage":{"recommendedSizes":{"width":"1000","height":"1000"},"mimetype":"image/jpeg","size":3591367,"hash":"74a7474b18a92a2baef49c5016766117af8bb0a4","id":"cmg0q69meqyub08506ue6gu50","filename":"dsc00263-160.jpg","category":"divesoft/","type":"image"},"secondImage":{"recommendedSizes":{"width":"1000","height":"1000"},"mimetype":"image/jpeg","size":25097796,"hash":"c31a11b0ab59b4f733f46f8823ad8ba92870ca7a","id":"cmg0q8uy5qyvt0850pp96ddc8","filename":"dsc-1609-2-enhanced-nr-full.jpg","category":"divesoft/","type":"image"}},"id":"#7","type":"component","lock":false,"position":2},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

Here’s what every Liberty user (and CCR diver in general) should adopt as habits.\n\n##### a) Rinse, flush, and dry\n\n* **Rinse external parts with fresh water** immediately after surfacing. Salt and debris can creep into small gaps, causing corrosion or salt crystals that lead to leaks.\n\n* **Flush breathing hoses / loop with fresh water**(diluent side, if permitted by your loop design) to remove saltwater or contaminants.\n \n* **Flush counterlungs

2** (both inhalation and exhalation bags) with clean fresh water, then drain and let them dry thoroughly.\n \n* **Keep the scrubber canister open** or ventilated while drying, but never let scrubber granules go soggy or be left wet.\n\n##### b) Disinfection of the breathing loop\n\nBecause your loop and counterlungs become an extension of your lungs, microbes matter. In between dives (especially over multiple dives in a day) you should:\n\n* **Remove any fluid** from exhaust hoses or water traps,\n\n* **Use a mild, CCR-safe disinfectant** to treat the breathing loop, DSV, BOV, and counterlungs (e.g. virucidal/disinfectant solutions recommended by manufacturer or known safe agents).\n \n* **Rinse thoroughly with fresh water** afterwards, to avoid residual chemicals.\n\n##### c) Inspect and lubricate O-rings and seals\n\n* Each time you assemble or disassemble components (lungs, covers, ports, valves), inspect all accessible O-rings for nicks, cuts, deformation, or hardness.\n\n* Use a proper oxygen-compatible lubricant (thin film) on O-rings. Don’t over-lubricate — excess grease can attract grit or degrade over time.\n\n* Replace O-rings that show any sign of wear.\n\n##### d) Battery care and power management\n\n* Maintain optimal battery charge levels. Avoid deep discharges or leaving cells entirely flat for extended periods, as this degrades capacity over time.\n \n* If your CCR uses removable or rechargeable batteries (for electronics, controllers, displays), store them partially charged if storing the unit long term.\n \n* Monitor battery voltage and state-of-health — if cells begin to show early degradation, schedule replacement sooner.\n \n##### e) Desalination after saltwater dives\n\n* After diving in seawater, especially in warm tropical conditions, thoroughly flush all metallic, anodised, or exposed parts (bolts, housings, manifold, external parts). Salt crystals accelerate corrosion and may cause tight spots, galvanic behaviour, or leak paths.\n\n* In humid, salty environments, even storing in protective bags doesn’t completely spare salt creep — ensure full rinsing.\n\n##### f) Wing / buoyancy bladder\n\n* Don’t forget your wing (lift bladder). Rinse it internally (inflate partially, flush inside), disinfect internally (if geometry allows), rinse, and ensure it is dry (or at least moisture-free) before storage.\n\n* Inspect internal seam lines, inflator hoses, inflation/deflation valves for salt deposits or evidence of wear.\n\n##### Why this user care matters\nAs the training site RebreatherPro notes:\n\n*“If you take the time to keep up with day-to-day maintenance then you will reduce the possibilities of failures, but also help to make it work more efficiently and extend its life.”* \n[Rebreatherpro-Training](https://www.rebreatherpro-training.com/general-rebreather-care-and-maintenance-ptf342?utm_source=chatgpt.com)\n\nIn short: diligent user maintenance doesn’t replace factory service, but it reduces the risk of sudden failures, extends component life, and keeps your unit in shape until its scheduled professional servicing.\n\n### Part 2: Authorised / Factory Service — What, When, and Why\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/85533c1865d4e16522e9369da6ec66d50b93a719_photo-daniel-valek_1000_600.webp)\n\nNo matter how careful you are, certain maintenance tasks are better left (or required by warranty) to authorised service centers or factory technicians. A CCR is life-support equipment, and many internal parts are not accessible or advisable for user servicing. Here’s how to structure your service schedule and what to expect, with some Divesoft-Liberty–specific guidelines.\n\n##### Why professional service is essential\n\nWhen you’re heading off to a remote dive destination, you can’t afford to discover a cracked counterlung, a failed O-ring, or misadjusted regulators right before your first dive.\nRegular professional service is your guarantee of reliability — professionals will disassemble, inspect, pressure-test, replace wear parts, verify alignment, and ensure all parameters (e.g. intermediate pressure, electronics, solenoids) are within specification.\n\n

2Indeed, many CCR manufacturers stipulate service intervals. For example, an authorised Poseidon service center states that Poseidon CCRs must be serviced at least every two years (104 weeks) by qualified personnel. \naltalena.com.au\n\n##### Divesoft / Liberty service guidelines\n\n[Divesoft publishes](https://www.divesoft.com/en/support/ccr-liberty-rebreather/service-operations?utm_source=chatgpt.com) a schedule of recommended services and quoted parts for the Liberty. Some highlights (as of current published data):\n\n*  Replacement of corrugated breathing hoses every 5 years for loop hoses (backmount) or side mount, as salt aging/creep may degrade hose materials. \ndivesoft.com\n\n*  Replacement of intermediate pressure (IP) hoses and high pressure (HP) hoses every 5 years (or per configuration) \ndivesoft.com\n\n*  Regular service of MAVs, first stages, OPVs with sealing components, cleaning, relubrication, and pressure testing. \ndivesoft.com\n\nAlso, the Divesoft service operations page includes cost and scope for many of these tasks — e.g. full refurbishment, replacement of hoses, cleaning + disinfection, etc. \n[divesoft.com](https://www.divesoft.com/en/support/ccr-liberty-rebreather/service-operations?utm_source=chatgpt.com)\n\n##### Recommended service intervals (general CCR practice, adapted)\n\nBelow is a realistic schedule (you should always follow Divesoft’s latest manual recommendations):\n\n| Interval               | What to do                                                                                                              | Reason / notes                                                                           |\n| ---------------------- | ----------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- |\n| **Annually**           | Full inspection, cleaning, seal replacement, pressure test, electronics check, flow checks, solenoid clean, calibration | This is the “basic tune-up” that catches wear early                                      |\n| **Every 3 years**      | In addition to annual tasks: consider battery replacement (if applicable)                                               | Batteries (especially lithium or rechargeable packs) degrade over time even with low use |\n| **Every 5 years**      | Replace all breathing hoses (corrugated loops), replace IP/HP hoses, bulkhead O-rings, solenoid O-rings                 | Hose material ages, loses elasticity, becomes susceptible to leakage or collapse         |\n| **On fault detection** | If any abnormal readings, sensor drift, leaks, crack, corrosion, etc.                                                   | Don’t wait until next scheduled service — schedule immediate inspection                  |\n\n\n\nNote that some service centers (for other CCR brands) recommend doing the full body service every 36 months (3 years) as a baseline. For example, East Coast Divers describes a 36-month service involving disassembly, cleaning, inspection, and replacement of recommended parts. \n They also note that for heavy use, you might shorten that interval. \n[East Coast Divers](https://ecdivers.com/equipment-service/ccr-rebreather-service/?utm_source=chatgpt.com)\n\n##### Example: what a Liberty full service should cover\n\nAlthough I don’t have the full internal Divesoft service checklist (your “attached documents”), based on what Divesoft publishes, the service should include:\n\n* Disassembly of MAVs, first stages, OPVs, cleaning, replacing all sealing parts, relubrication, assembly, and underwater pressure test\n\n* Disassembly, cleaning and inspection of the ADV (membrane), replacing O-rings, testing\n\n* Cleaning + disinfection of gas paths and components exposed to breathing gas\n\n* Calibration of electronics, firmware update, sensor diagnostics\n\n* Replacement of recommended hoses (if 5-year threshold), replacement of sealing / O-ring kits\n\n* Inspect structural components (frame, backplate, manifold), connectors, wiring, cable terminations\n\n* Final leak test, functional test, full certification and service report\n\nIf any wear or damage is found beyond tolerances, the service center should contact you to approve additional repairs or part replacements.\n\n##### Consequences of skipping or delaying service\n\n* Increased chance of in-dive failures (leaks, O-ring blowouts, sensor faults)\n\n* Degradation of hose materials, leading to microcracks or collapse under pressure\n\n* Corrosion or salt intrusion in internal passages, leading to restrictive flow or malfunctions\n\n* Warranty invalidation (many manufacturers require regular authorised servicing)\n\n**Loss of trust in your own equipment — the last thing you want is a failure during an expedition**\n\nAs a diver put it on a forum:\n\n*“Note, just because a manufacturer offers parts for sale, it does not mean that you can get parts in a timely manner … Shearwater will not send you parts to fix their products.”* \n[scubaboard.com](https://scubaboard.com/community/threads/rebreather-service-self-or-factory-only.652384/?utm_source=chatgpt.com)\n\nThat is, in remote locations, you may 

2not be able to source critical spare parts — so you must rely on the fact that your CCR is already fully serviced and trustworthy.\n\n### Final Thoughts\n\nOwning a CCR Liberty (or any advanced CCR) is an investment — in performance, freedom, and safety. But that investment only pays off if you match it with proper maintenance discipline and regular professional servicing.\n\nUser-level care after each dive (flushing, disinfection, inspection, lubrication, battery care) is your first line of defense\n\nProfessional service at scheduled intervals is your safety net, ensuring that hidden wear or degradation is caught and corrected\n\nSkimping on service is like skipping oil changes on a high-performance engine — sooner or later something will go wrong at the worst possible moment\n\nIf you’re headed off on a remote dive trip, you don’t want to discover a cracked counterlung, a leaking hose, or failed electronics right before your first dive. Regular servicing is your insurance.  \n\nAuthor: Jakub Å imánek","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":2832782,"hash":"b93224652d9b0106128b15aa09f5eba9480a4ed3","id":"cmgermaawue8s0850mld5ju7y","filename":"titulka-photo-daniel-valek.jpg","category":"divesoft/","type":"image"},"publishDate":"10/02/2025"},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#21","type":"component","lock":false,"position":5},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":{"urlNewWindow":true,"url":"https://www.facebook.com/divesoft/"},"youtubeUrl":{"url":"https://www.youtube.com/@divesoft_tv","urlNewWindow":true},"instagramUrl":{"url":"https://www.instagram.com/divesoft/","urlNewWindow":true},"contacts":"**Divesoft s.r.o.**  \nHálkova 2495  \n413 01  Roudnice nad Labem  \nCzech Republic  \nTel.: +420 416 857 057  \nE-mail: [email protected]","twitterUrl":{"url":"","urlNewWindow":true,"pageId":"cjv3l26tp004p0836i54n4u7a"}},"id":"#1","type":"component","lock":false,"position":6}],"id":"root","idBuffer":"#25","lastCommit":"37e21045-046c-4601-8288-0350ec7f527c"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cm9cnfr52fd98080350l77m3z":{"id":"cm9cnfr52fd98080350l77m3z","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[{"type":"id","generated":false,"id":"Tag:cjv3szrcv01bz0836yo8myb0r","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cl28w8de8gdo20858cjkbufee","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww05zc1b5d0803zglvz927","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww0t651b710803pcl02cn4","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cmfp50qhi00lk08324ek37f9g","typename":"Tag"}],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cm9cnfr5nfd9f0803ub46t5lg","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cm9cnfr5nfd9f0803ub46t5lg":{"id":"cm9cnfr5nfd9f0803ub46t5lg","name":"CCR diving certification courses: how it goes and what you need to know","createdAt":"2025-04-11T10:33:31.451Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

Note: each training agency (e.g., DIVESOFT, partner instructor groups) may tailor it, but the structure should meet or exceed [RTC] (https://rebreathertrainingcouncil.org/?utm_source=chatgpt.com) (or equivalent) standards.\n##### Prerequisites\nBefore enrolling, divers are typically expected to have:  \n* Advanced Open Water (or equivalent)\n* Nitrox certification (Advanced Nitrox with stage cylinder recommended)\n* Strong buoyancy control and trim\n* A minimum number of logged dives often 30–50 (100 recommended)\n* Recent diving activity\n* Medical clearance as required  \n\n**These ensure you’re ready for the cognitive load and risks CCR introduces.**\n##### Course Phases \n1. 1.\t**Classroom / Theory**  \nTheory is meant to prepare you for whatever the real world underwater has in store for you. You should be able to understand and fully grasp the principles of rebreather diving.\nYou will study diving p

2hysiology (O₂ toxicity, CO₂ retention, hypoxia), gas control, loop mechanics, electronics, failure modes, emergency decision trees, and dive planning (diluent, bailout, decompression).\n2.\t**Confined Water / Pool Work**  \nIn the pool, you will get used to new equipment that is so different from the device you are used to. In the confines of the pool, you will be safe and confident enough to try everything you need before you are exposed to the other influences of the real underwater world.\nUnder instructor supervision, you practice:\n* Loop pre-breathing, flood management, purge/clear procedures\n* Manual PO₂ control (if applicable)\n* Bailout drills (switching to open circuit)\n* Buoyancy and trim control with full loop\n* Simulated failures (sensor dropouts, flooding, etc.)\n3.\t**Open Water Dives**  \nUnder the supervision of an experienced instructor, you will learn everything you need to know for self-sufficient diving with a rebreather in real conditions.\nYou’ll execute a series of 8 dives —progressing in complexity and depth (commonly to 30 m for entry-level). Tasks include:\n* Detailed pre-dive checklists\n* In-water loop monitoring and adjustment\n* Controlled ascents and gas switching\n* Emergency responses (e.g. high PO₂, cell failure, flood)\n* Post-dive checks, maintenance, sensor calibration, and data logging  \n4.\t**Certification Debrief & Final Assessment**  \nYou will be evaluated on theory, skills, emergency handling, and dive logs. The instructor confirms that you are competent and comfortable to proceed.  \n\nTimeframe is often **5–7 days**, depending on your pace and local conditions.\n________________________________________\n\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/b94b00c7cfd405d94377f1a943bb10a1e8234ebd_ccr-classes.jpg)\n\n### Risks & Reality: Why Rigorous Training Is Non-Negotiable  \nCCR diving introduces hazards not encountered in open circuit: **hypoxia, hyperoxia, hypercapnia, CO₂ retention, sensor failure, flooding, loop failures**. Because of these, every CCR diver relies heavily on systematic habits, checklists, and overlearning of critical drills.\n\nAs experienced technical diver and educator Phil Short once put it:  \n*“Training is not just about learning to operate the machine — it’s about learning to think like a rebreather diver.”*  \n— **Phil Short, explorer and diving educator** [(source)](https://www.tdisdi.com/?p=48407&utm_source=chatgpt.com)  \n\nThat mindset — cautious, methodical, and self-aware — is what turns complex equipment into a safe tool for exploration.\nTherefore, your instructor, training syllabus, and continued practice after certification are your real life-zone of safety.\n________________________________________\n### The Path of Progression  \nOnce certified as an entry-level CCR Air Diluent Diver (40 m), you can progress to:   \n1.\t**CCR Air Diluent Decompression** (30 m)  \n2.\t**CCR Air Diluent Decompression** (40 m)  \n3.\t**CCR Trimix** (60 m) — introduces helium and decompression management  \n4.\t**Advanced Trimix** (100 m+) — for deep exploration and technical diving  \n\n\nEach step builds upon experience logged on your rebreather and expands both knowledge and confidence.  \n\n##### RTC & ISO: The Framework Behind Quality CCR Training  \n[The Rebreather Training Council (RTC)](https://rebreathertrainingcouncil.org/?utm_source=chatgpt.com) brings together major training agencies to align minimum curricula and safety expectations for rebreather courses. RTC also works with manufacturers via CRISAG to align diver training and equipment considerations. Crucially, RTC holds Category C liaison status with ISO/TC 228 WG 1 (Diving Services) and contributed to drafting the ISO rebreather diver training standards now in force. rebreathertrainingcouncil.org+2rebreathertrainingcouncil.org+2\n\nCurrent ISO standards for CCR diver training:  \n* ISO 24804:2022* — Rebreather diver training: No-decompression diving. Competencies for rebreather dives to 30 m without mandatory decompression using nitrox. iso.org+1\n* ISO 24805:2022 — Rebreather diver training: Decompression diving to 45 m. Competencies for dives requiring decompression to 40 m on nitrox or to 45 m on trimix. iso.org+1\n* ISO 24806:2023 — Rebreather diver training: Decompression diving to 60 m. Competencies for decompression dives to 60 m using helium-containing mixes. iso.org\n* ISO 24807:2023 — Rebreather diver training: Decompression diving to 100 m. Competencies for decompression dives to 100 m using helium-containing mixes. iso.org\n\n(As background, RTC had earlier published its own Level 1–3 technical standards; many agency syllabi map closely to these levels and now align with ISO.) rebreathertrainingcouncil.org+1\n\n**Why this matters**: ISO/RTC alignment gives students and operators a common language—depth/gas limits, core skills, evaluation criteria—so your certification’s implications are clear when you travel or join new teams.\n\nExplorer and educator** Jill Heinerth** puts it plainly:  \n*“Training agencies have the opportunity to set the ground rules right from the beginning and guide divers to recognize that the general safety rules have been developed from practical experiences.”* [intotheplanet.com](https://www.intotheplanet.com/)\n\nThat culture—standards, repeatable habits, and instructor accountability—turns complex equipment into a safe tool for exploration.\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/af5c388ad5437f1d425c18bab48edad23eb3c5b7_8460-divesoft-dna-divesoft-nitrox-analyzer-app-02.png)  \n\nTraining on Liberty: What to Look for\nIf you choose to train using the [Liberty](https://www.divesoft.com/en/products/ccr-liberty) rebreather, here are some criteria to keep in mind so your training is meaningful and future-proof:\n•\tUnit-specific instruction — CCR certification is machine-specific. If your training is on [Liberty] (https://www.divesoft.com/en/products/ccr-liberty), that’s the unit you should continue to use (or do a crossover for others).\n•\tRedundancy & failure simulation — your course should include drills for sensor dropouts, loop flooding, solenoid malfunctions, etc.\n•\tMaintenance & c

2alibration training — you should learn to inspect, replace, and calibrate O₂ sensors, scrubber media, and seals.\n•\tExtended scenario dives — look for courses that go beyond ideal conditions (currents, limited visibility, off-gassing complexity).\n•\tEmphasis on human factors & non-technical skills — your course should also teach judgement, situational awareness, communication, and error recognition.\nPost-certification, commit to regular practice, maintain checklists, retrofit firmware updates, and engage with the [Liberty / CCR community to stay sharp.] (https://www.facebook.com/groups/104210749916042)\n________________________________________\n\nFinal Thoughts & Advice\nCCR Liberty diving holds tremendous promise — elegance, efficiency, and deeper exploration. But it is not a shortcut. The safety margin in rebreather diving is less forgiving than ever, so you must:\n1.\tChoose a training provider that adheres to or exceeds RTC / ISO standards\n2.\tBe ready for intensive theory, hands-on confined water, and challenging open-water drills\n3.\tTreat checklists and emergency procedures as sacred\n4.\tPractice regularly after certification\n5.\tRespect your limits, and expand gradually\nDive safe, stay curious — and let Liberty open new windows into the underwater world.\n\n\nAuthor: Jakub Å imánek","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":647608,"hash":"9f1abb59838a49a01fa222cd19f9ae12101d8e67","id":"cmgyrza0s0hyx0850fo7vlxwx","filename":"titulka-ccr-classes.jpg","category":"divesoft/","type":"image"},"publishDate":"10/13/2025"},"id":"#2","type":"component","lock":false,"position":2},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#9","type":"component","lock":false,"position":3},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":4}],"id":"root","idBuffer":"#11","lastCommit":"62218c15-ec4d-4cdf-8ee1-72cfd235564e"}},"annotations":[],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"Page:cm9coazvwfdk10803da2ixhdm":{"id":"cm9coazvwfdk10803da2ixhdm","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[{"type":"id","generated":false,"id":"Tag:cjv3szrcv01bz0836yo8myb0r","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cl28w8de8gdo20858cjkbufee","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:clw52z09zlclk0735mxb7v53p","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cm5ww05zc1b5d0803zglvz927","typename":"Tag"},{"type":"id","generated":false,"id":"Tag:cmfp50qhi00lk08324ek37f9g","typename":"Tag"}],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cm9coazwffdk80803qwzztu2b","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cm9coazwffdk80803qwzztu2b":{"id":"cm9coazwffdk80803qwzztu2b","name":"Life-changing experience: why you should try CCR diving","createdAt":"2025-04-11T10:57:49.119Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

That’s what closed-circuit rebreather (CCR) diving offers: freedom, time, and a connection with the underwater world that open-circuit scuba can’t match. For me, it was more than just a new way to dive — it was a life-changing experience that redefined everything I thought I knew about the ocean.","content":"From the first moment I learned about rebreathers, I was fascinated. I still remember being sixteen when the Dräger Dolphin appeared on the market — that small white box that promised longer bottom times, shorter decompression, warm breathing gas, and almost no bubbles. It was a semi-closed circuit system, and at the time, I knew almost nothing about rebreathers except what I had read in old Svazarm* diving manuals. Those books, written during the socialist era, were my first window into the world of technical diving, and they sparked a passion that would later define my life.\n\nWhen the yellow Inspiration rebreather was introduced, it completely blew my mind. An electronically controlled, fully closed circuit system that optimized the use of breathing gas, allowing deep, long dives — it was like something out of science fiction. I devoured every article, every bit of literature I could find, preparing myself for the day I would finally dive with one.\n\n![Dan Sun wreck diving](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/4a30559a951d7aa57465cdfce1be56d3b2f751f0_0n2a6580-enhanced-nr.jpg)\n\nThat day came when I got the chance to dive with the first functional prototype of the [Liberty rebreather](https://www.divesoft.com/en/products/ccr-liberty). It was a dream come true. Suddenly, I had access to adventures that would have been difficult, extremely expensive due to helium costs, or even impossible with open-circuit scuba. Theoretical knowledge is one thing, but the first-hand experience of buoyancy control, silence, and freedom that the [Liberty](https://www.divesoft.com/en/products/ccr-liberty) provided was something else entirely.\n\nI’ll never forget one of my first dives as a CCR diver — exploring a wreck at 30 meters with an air diluent. I spent nearly an hour inside and around the wreck, fully immersed in the experience. Normally, such a dive would require at least an hour of decompression, but this time my decompression lasted only twelve minutes. I was amazed — it felt like breaking the rules of physics, like bending time itself.\n\nYears later, as a seasoned CCR instructor trainer, I still felt the same sense of wonder. I remember diving the Spiegel Grove wreck at 40 meters with my friend [Joe Bosquez](https://www.youtube.com/watch?v=WILI-2KPKSs). With us was a group of recreational open-circuit divers. At first, the wreck was crowded, bubbles everywhere, but after a short while the noise faded and the place became ours alone. We drifted silently among massive goliath groupers, sharks, turtles, giant barracudas, and moray eels — the kind of peaceful, intimate underwater encounter that only rebreather diving can offer.\n\nAbout forty minutes later, a cloud of bubbles appeared above us — the same recreational divers returning for their second dive. They stayed for a brief moment before surfacing again. When our bottom time finally ended, we met them on the deco line and surfaced together. The contrast was striking: while they had just begun their second short dive, we were ending a single, long, relaxed, and unforgettable one.\n\n![wreck diving truck lagoon bikini atol](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/5c63badb12df8e78dc51d9c5992d15be2cad20b6_0n2a8348-enhanced-nr-edit.jpg)\n\nThat’s the magic of CCR diving. It gives you time — time to explore, to observe, to breathe in silence and become part of the underwater world rather than just a visitor. It’s more than a technical upgrade; it’s a transformation in how you experience diving itself.\n\nIf you’ve ever dreamed of staying longer below the surface, of exploring the ocean as freely as possible, CCR diving is a life-changing experience you should try. It opens a new world — one of silence, precision, and endless discovery.\n\n*Note: *“Svazarm” (Union for Cooperation with the Army) was a Czechoslovak organization active during the socialist period that trained civilians in various technical and military-related disciplines, including diving, aviation, and radio operation. Its diving manuals were among the first sources of underwater knowledge for many Czech and Slovak divers.*\n\n\nAuthor: [Jakub Å imánek](https://www.divesoft.com/en/about-us/jakub-simanek)","showTags":false,"showDate":true,"publishDate":"11/11/2025","image":{"mimetype":"image/jpeg","size":990049,"hash":"c7247dac333d189c52caf45683931d31a732f2f5","id":"cmhudijjfatpf08507egaidb5","filename":"titulka-experience.jpg","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

Choosing the Right Instructor — The Key Step in the Process\nThe first and most important step is finding a certified Liberty instructor. Without an instructor, it is not possible to order the unit or complete the mandatory CCR training.\nWhere can you find instructors?  \nDivesoft maintains an up-to-date list of certified instructors on its website:  \n👉 https://www.divesoft.com/en/instructors\n\n**Why is choosing the right instructor so important?**\n*\tYour instructor is your guide to the technology. They explain the differences between Liberty versions (Backmount vs. Sidemount), help assess your needs, and advise on suitable configurations.\n*\tThey help with the setup. This includes selecting cylinders, scrubber type, electronics, accessories, and bailout solutions.\n*\tThey submit the order. After you finalize your configuration on the Divesoft website and send it in, both you and your instructor receive a copy. The instructor reviews it and places the final order with Divesoft.\n*\tThey provide the mandatory training. Purchasing a CCR without proper training makes as little sense as buying an aircraft without a pilot license. Good references and mutual trust are crucial.\nHow to choose an instructor\n*\tCheck experience and references\n*\tConsider their specialization—caves, wrecks, deep diving\n*\tHave a consultation to see whether their teaching style suits you\n*\tIdeally select someone who can support you long-term, not just during the course\n\n![CCR Liberty](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/dcf5c65227bd952f48f27afffec53c62ecf5831f_dsc09523-32.jpg)\n________________________________________\n## 2. Choosing Your Liberty Model\nLiberty is a modular system available in two main versions:  \n\n**Backmount (BM) Liberty**\n*\tIdeal for technical and wreck diving\n*\tWorn on the back\n*\tExtremely stable and balanced platform  \n\n**Sidemount (SM) Liberty**\n*\tPopular in cave diving\n*\tVery compact\n*\tExcellent maneuverability in restricted spaces\n\n\n**Pre-built Sidemount Liberty units in stock  **  \n\nIf you want to avoid waiting, Divesoft often keeps pre-assembled Sidemount Liberty units in stock.\nThese can be delivered very quickly—often within just a few days.\n________________________________________\n## 3. Configuring Your Rebreather\nOnce you have an instructor, you’ll work together to configure your unit.\n[The Divesoft online configurator](https://www.divesoft.com/en/ccr-liberty?config=eyJ0cmVlSWQiOiI2Mjk3M2NmZmRlYWMzNWUzMDQ4MmFlYzAiLCJub2RlR3VpZHMiOltdLCJkZXRhaWxOb2RlR3VpZCI6IiIsInNldHVwRGV0YWlscyI6e30sImRldGFpbFNldHVwIjp7InF1ZXN0aW9uR3VpZCI6IiIsImFuc3dlckd1aWQiOiIifSwiYWNjZXNzb3J5Q2F0ZWdvcmllcyI6e30sImRldGFpbEFjY2Vzc29yeSI6eyJjYXRlZ29yeUd1aWQiOiIiLCJxdWVzdGlvbkd1aWQiOiIiLCJhbnN3ZXJHdWlkIjoiIn19&step=nodes

You fill in your configuration according to your instructor’s recommendations.  \n2. You submit the form to Divesoft directly from the configurator.  \n3. A copy is automatically sent to the customer, who will send it to the selected instructor.  \n4. The instructor places the final order with Divesoft.\n\nThis ensures you receive a configuration tailored to your experience, diving style, and long-term goals.\n\n![CCR Liberty](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/45ebcfdd93c85c4b157570022863f7e5dc2812c2_dsc02994-22.jpg)\n________________________________________\n## 4. Production and Delivery — How Long Does It Take?\nDivesoft manufactures Liberty units based on each customer’s chosen configuration.\nThis means:\n*\tPre-built Sidemount Liberty units can be delivered almost immediately.\n*\tCustom configurations require several weeks for production.\nLead time varies with factory workload\nDuring periods of high demand, production queues can be longer. Your instructor will tell you the current delivery estimates.\n________________________________________\n## 5. Handover and Training\nOnce your unit arrives, the final steps include:\n*\tInstructor handover of the rebreather\n*\tInitial setup and system orientation\n*\tMandatory CCR Liberty training, which is essential for safe operation\nOnly after completing the training are you fully prepared to use your Liberty rebreather responsibly.\n________________________________________\n## Conclusion\nBuying a Liberty rebreather from Divesoft is a coordinated process built around working with a certified instructor, ensuring every diver receives a unit tailored to their needs and the knowledge to operate it safely. From choosing an instructor, through configuration, to production and training—everything is designed to provide you with both a world-class rebreather and the necessary support.\nIf you are considering purchasing your own Liberty, the first step is to select an instructor and arrange an initial consultation. This begins your journey toward one of the most advanced rebreathers available today.\n\n\nAuthor: [Jakub Å imánek](https://www.divesoft.com/en/about-us/jakub-simanek)\n","showTags":false,"showDate":true,"publishDate":"11/24/2025","image":{"mimetype":"image/jpeg","size":397313,"hash":"86e082e660c4096d5ae7580ae668036865db59c0","id":"cmid53m50g9w108508mpzmn5z","filename":"titulka-purchase.jpg","category":"divesoft/","type":"image"}},"id":"#2","type":"component","lock":false,"position":1},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yqs3tp71"},"id":"#3","type":"component","lock":false,"position":7},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":8}],"id":"root","idBuffer":"#9","lastCommit":"ff38de58-6ccd-4c3f-83fd-eb6b19684aed"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:cm9cobgg4fdlc0803ulfp6mjh.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cm9cobgg4fdlc0803ulfp6mjh.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cm9cobgg4fdlc0803ulfp6mjh.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:cm9cobgg4fdlc0803ulfp6mjh.annotations.0":{"key":"title","value":"Liberty rebreathers purchasing process: what to expect when you order","__typename":"PageAnnotation"},"PageTranslation:cm9cobgg4fdlc0803ulfp6mjh.annotations.1":{"key":"perex","value":"The **[Liberty rebreather](https://www.divesoft.com/en/products/ccr-liberty)** rebreather from the Czech company [Divesoft](https://www.divesoft.com/) ranks among the world’s top [CCR systems](https://www.divesoft.com/en/blog/5-basic-principles-of-rebreather-and-one-extra).

Stay safe and precise with Divesoft.","content":"\n\nClosed-circuit rebreathers (CCRs) have expanded the boundaries of what divers can safely explore — deeper depths, longer runtimes, and environments once considered unreachable.\nBut with this advanced technology comes a new level of responsibility: **proper equipment selection and preparation.**\n\n“*Rebreathers are nothing more than tools to allow you to remain underwater for an extended period.*”\n**  \n— Jeffrey E. Bozanic, Mastering Rebreathers (Second Edition)**\n\nTools, however, are only as reliable as the diver who maintains and configures them. This guide focuses on the supporting equipment that ensures your CCR diving is safe, efficient, and fully under control.\n\n### In-Water Equipment: Beyond the Rebreather\n#### BCD / Wing System\n\nUnlike open-circuit setups, a CCR diver must be ready for the unlikely — but potentially critical — **flooding of the rebreather unit.**\nA fully flooded loop or scrubber can instantly add up to **10 kilograms of negative buoyancy**, which must be compensated for by your buoyancy system.\n\nUnfortunately, most manufacturers underestimate the lift required for CCRs, offering wings that are simply too small.\nChoose a **BCD or wing with generous lift capacity**, stable geometry, and a durable bladder to remain positively buoyant even if your unit floods completely.\n\n#### Dive Computers\n\nThe [Divesoft Liberty CCR] (https://www.divesoft.com/en/products/ccr-liberty)\nis built with** full redundancy** — dual controllers, dual displays, and dual power supplies.\nFor most dives, that’s all you need. However, many experienced technical divers still carry a [Divesoft Freedom](https://eshop.divesoft.com/products/computers-freedom?currency=CZK)\n computer as an **independent backup**, especially on expedition-level dives.\n\nThe Freedom provides an additional, fully autonomous depth and decompression reference — because in technical diving, redundancy equals safety.\n\n#### Gas Analyzers\n\nEven for recreational CCR diving, a gas analyzer is an absolutely essential piece of safety equipment. **Every diver must personally analyze the gas mixture** in their cylinders and verify the actual oxygen and, when applicable, helium content.  \n\nAs Jeff Bozanic emphasizes, “*You must personally analyze or directly observe the analysis of the breathing gas you will be using.*”\nAn unknown or incorrectly analyzed mix can lead to hypoxia, hyperoxia, or serious decompression errors.\n\n![Divesoft DNA nitrox analyzer](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/144ef43e23c45711d9631c192eb2563c7d9b2280_dna.jpg)\n\nBeginning CCR divers should at least own a nitrox analyzer, such as the [Divesoft DNA] (https://www.divesoft.com/en/products/analyzers/dna).  \nHowever, it is better to invest directly in a combined He/O₂ analyzer, such as the [Divesoft He/O₂ Analyzer] (https://www.divesoft.com/en/products/analyzers/analyzer-he-o2) or the more compact [Divesoft SOLO] (https://www.divesoft.com/en/products/analyzers/analyzer-solo).  \nEven if you start diving with a plain air diluent, you will very soon progress to deeper CCR dives where trimix anal

2ysis becomes essential — requiring accurate measurement of both oxygen and helium content.\n\n#### Fins: Precision and Buoyancy Balance\n\nFin choice is more than comfort — it directly impacts your **trim and propulsion contro**l.  \nFor CCR and technical diving, **shorter, wider fins with stiff blades** are ideal. They deliver precise feedback for techniques like the frog kick, modified flutter, or back kick, enabling fine positioning without disturbing silt or fragile environments.\n\n##### Fin buoyancy matters:\n\n* In cold water with a drysuit, heavy rubber fins offset the positive buoyancy of drysuit boots, maintaining a balanced horizontal trim.\n\n* In warm water and wetsuits, heavy fins cause the legs to sink. Choose lightweight or neutrally buoyant fins for a stable, efficient posture.\n\nA well-trimmed diver conserves gas, reduces workload, and optimizes scrubber efficiency — improving both safety and performance.\n\n#### Surface Marker Buoy (SMB / DSMB)\n\nEvery CCR diver should carry a Delayed Surface Marker Buoy (DSMB) — it’s not optional.\nWithout bubbles to mark your position, a DSMB is your only visible link to the surface.\n\nIt serves several key purposes:\n\n1. Emergency ascent signaling: alert surface support in the event of an equipment or gas issue.\n\n3. Marking your ascent line: useful in open water or poor visibility where no fixed line is available.\n\n1. Decompression in currents: provides a stable reference point while maintaining your position in moving water.\n\nChoose a **high-visibility DSMB** (orange or yellow, minimum 1.5 m) and a **reliable reel or spool**. Practice deployment frequently, including from depth and while neutrally buoyant.\n\n“*Evaluate the conditions before every dive; ensure that they fit your personal capabilities*.”  \n**— Jeffrey E. Bozanic, Mastering Rebreathers (Second Edition)**\n\nFor diving to greater depths, you need a rope that is long enough to be able to **release a buoy from the bottom or from the deck of a wreck**. This is necessary if you lose your bearings and cannot return to the ascent rope. \n\n**The only option then is to rely on a line with a buoy**. The [Divesoft reel] (https://www.divesoft.com/en/products/others/reels) is a perfect and reliable choice that will suffice for all conceivable dives. It has saved the lives of many divers in this way.\n\n![Divesoft reel](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/cccb9fed46ba9390518faf2109cb2904fafb6525_reel.jpg)\n\n#### Bailout Configuration: Your Last Line of Defense\n\nIn CCR diving, your bailout system is your true safety reserve — a fully independent life-support system.\nIt must allow you to ascend safely on open circuit, from the deepest and most demanding point of your dive, with all decompression stops completed.\n\n##### Sizing and Gas Planning\n\n**Always plan bailout gas for the worst-case scenario**.\nThat means considering depth, decompression time, current, stress, and elevated SAC rates.\nBailout gases are **for emergencies only** and should never be consumed during normal operation.\n\nExperienced CCR divers maintain several bailout cylinders with different gas mixes — typically deep, intermediate, and decompression gases — and select the right combination for each dive.\n\nFor example,   \n— I personally use a total of six different tanks: an air tank for simple dives to 30 m, Helitrox 30/30 for dives to 40 m or as travel/deco gas, 15/60 and 12/80 for great depths, and finally EAN50 and oxygen as decompression mixtures.\n\n##### Regulator and Hose Routing\n\nClean routing and reliability are key:\n\n* Hoses should **run along the cylinder** for a streamlined, snag-free setup.\n\n* **Use a swivel turret first stage** or angled ports for flexibility and tidy routing.\n\n* The [Divesoft Technical Adapter] (https://www.divesoft.com/en/products/others/apeks-technical-connection) for Apeks DST \n provides perfect hose alignment for CCR bailout systems.\n\n\n##### Additional Utility Connections\n\nA well-equipped bailout first stage can do more than deliver breathing gas.\n* An **inflator-style quick-connect hose** adds valuable versatility:\n\n- Serves as an **independent drysuit inflation source** if onboard diluent isn’t accessible.\n- Can **connect to the Manual Addition Valve (MAV)** for manual oxygen addition when needed.\n\n* Add **high-flow connectors like Swagelok or Omniswivel** to connect on-board and off-board gas in case of loss or for complex dive profiles.\n\nThis setup ensures full control over loop oxygen and buoyancy — even when operating on bailout gas.\n\n“*Failure to plan for bailout is planning to fail. Redundancy is not optional — it’s what keeps you alive when everything else stops working.*  ”\n**— Jeffrey E. Bozanic, Mastering Rebreathers (Second Edition)\n**\n\n### Service and Spare Parts: What Keeps You Diving\n\nA well-prepared diver’s toolkit is as important as the rebreather itself.\nHaving the right parts and tools on hand can turn potential dive cancellations into minor delays.\n\n**Recommended Service Kit**\n\n* O-rings and seals (oxygen-compatible)\n\n* Spare oxygen sensors, properly calibrated and stored\n\n* Lubricants: oxygen-safe (e.g., Krytox®)\n\n* Tools: hex keys, spanners, O-ring picks, flow meters, IP gauges\n\n* Hoses and valves for O₂, diluent, and bailout systems\n\n* Disinfectants: iodine-based or Virkon S®\n\n* Spare batteries and cables for HUDs, handsets, and analyzers\n\n“*Properly caring for equipment after every dive will extend its usable life, preserve its value, and, most importantly, minimize the chance of failure during a dive.*”  \n**— Jeffrey E. Bozanic, Mastering Rebreathers (Second Edition)**\n\nDivesoft’s Philosophy: Precision in Every Breath\n\nAt Divesoft, we believe that safety begins long before you enter the water.\nFrom Liberty CCR systems with full redundancy, to Freedom dive computers and gas analyzers, every product is engineered to support your dive with precision and reliability.\n\n\n![](https://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/af5c388ad5437f1d425c18bab48edad23eb3c5b7_8460-divesoft-dna-divesoft-nitrox-analyzer-app-02.png)  \n\n\nAuthor: Jakub Šimánek","showTags":false,"showDate":true,"image":{"mimetype":"image/jpeg","size":397950,"hash":"31975e7693d9a9ba9df36050e6a2592d73822fd6","id":"cmh39kawx2i960850nldgnr40","filename":"titulka-equipment.jpg","category":"divesoft/","type":"image"},"publishDate":"10/27/2025"},"id":"#2","type":"component","lock":false,"position":4},{"name":"ProductShowcase","data":{"componentTemplateId":"cm9h4wr6ugjv10803yq

C

2ousteau’s shows and was tempted to try diving myself. At that time, it was practically impossible in our country, but later the opportunity arose. I tried it and found that it was exactly what I enjoyed. From that moment on, I stopped pursuing other sports, even those that were interesting and technically demanding, like paragliding. It became clear that diving was the right sport for me.\n\nFor me, diving is primarily unlimited movement in complete calm. I enjoy observing underwater life, but what truly draws me even in lifeless terrain or deep inside a cave - is the act of diving itself. It’s like walking in the woods or on a mountain trail, but with breathing apparatus, a computer, flashlights, a compass, guide lines, and other technical equipment. This interest in well-prepared, perfectly functioning technology is the second aspect of diving that captivates me. I like knowing every detail and being able to control it.\n\nOne unforgettable experience showed me that neither duration nor depth, nor even the equipment, determines a dive’s significance. While snorkeling in Norway, above the Arctic Circle, a killer whale swam up to me while hunting herring. It looked at me, and when it saw my clumsiness and inability to stun a herring with a fin stroke, it turned and gave me one. That day, we had herring for dinner. I had heard that killer whales share their food, but seeing it firsthand was incredible\n\nCurrently, I focus on automated testing of diving equipment. Our laboratory allows us to measure parameters and test breathing apparatus and other gear even at depths a diver could never reach. These machines can withstand extreme conditions and help identify areas where equipment needs improvement or modification.\n\nMy journey with Divesoft started simply. I noticed that certain technical equipment didn’t exist or could be improved, so I began making it myself. Friends wanted to try it, and from there, founding Divesoft and manufacturing it professionally was the natural next step. For me, a diver should never feel limited by equipment. That’s why CCR is my choice, I can dive as long as I want, not just until my gas runs out.\n\nDiving plays a fundamental role in my life because I’ve combined my hobby with my profession. When I’m not diving, I work on developing diving technology and when I’m not working, I can dive. It feels like the right choice. After work, I enjoy working in the workshop, where I can work on something that combines mechanics, physics, electronics, and programming. I imagine the ideal relaxation as precision work and the process of finding solutions.\n","contact":"","images":[{"id":"1","image":{"mimetype":"image/jpeg","size":712211,"hash":"61484d4be63ae875fd3661e898eace659705f550","id":"cmlgfwrdolmcv0800crv1ua97","filename":"prochaska.jpg","category":"divesoft/","type":"image","alt":"photo of Aleš Procháska, Company Co-Founder from Divesoft"}}],"equipment":[{"id":"1","title":"Liberty <light>Heavy</light>","eshopUrl":{"url":"/en/products/ccr-liberty","pageId":"cjv3rpryz00iw0836lc0zx81j"},"image":{"mimetype":"image/png","size":5119796,"hash":"306f09c9913b45581e7a0c11c698358833067623","id":"cmnq5f3mqhznk0800xitdqu7w","filename":"liberty-heavy.png","category":"divesoft/","type":"image","alt":"Liberty Heavy"}},{"id":"2","title":"ANALYZER He/O<sub>2</sub>","eshopUrl":{"url":"https://www.divesoft.com/en/products/analyzers/analyzer-he-o2"},"image":{"mimetype":"image/png","size":3203637,"hash":"c291e73219753bfa13df291c799813b3c9f0990c","id":"cmnq5h86hhzpb0800r68torxv","filename":"heo2.png","category":"divesoft/","type":"image","alt":"Analyzer He/O2"}}],"activeTab":"1"},"id":"#2","type":"component","lock":false,"position":1},{"name":"JsonLD","data":{"jsonLD":"{\n  \"@context\": \"https://schema.org/\",\n  \"@type\": \"Person\",\n  \"@id\": \"https://www.divesoft.com/en/about-us/ales-prochaska#person\",\n  \"name\": \"Aleš Procháska\",\n  \"givenName\": \"Aleš\",\n  \"familyName\": \"Procháska\",\n  \"jobTitle\": \"Company Co-Founder\",\n  \"knowsAbout\": [\n    \"Cave diving\",\n    \"Trimix diving\",\n    \"CCR diving\"\n  ],\n  \"worksFor\": {\n    \"@type\": \"Organization\",\n    \"@id\": \"https://www.divesoft.com/#organization\",\n    \"name\": \"Divesoft\",\n    \"url\": \"https://www.divesoft.com/\",\n    \"logo\": \"https://www.divesoft.com/assets/divesoft/images/logo.svg\"\n  }

Once I tried scuba, it quickly became my new favorite sport. What I enjoy most is the space-like feeling underwater: quiet, peaceful, weightless. Especially on closed circuit, everything slows down in the best way. The most memorable dives for me have been caving in Sardinia, walking kilometers deep into the cave system, passing through multiple siphons with sand and crystalclear water. It’s a mix of exploration and concentration that I find addictive. I’m most at home in the dark. Think Czech dams, where every dive feels like a night dive. And that suits me perfectly. I spend most of my time on Czech dams like Slapy and Orlík, where you can see everything from old house foundations to trees and big catfish hiding in the roots. I’m happiest when I can dive every week. For me, diving is the ultimate form of recreation, no matter the conditions. Weekend dives on local dams, a safari boat on the Red Sea, or caving in zero visibility, it all has its own charm.\n\n

2My Divesoft story began when I was a Freedom diver and a bit of a nitpicker. A friend introduced me to AleÅ¡ Procháska, and in 2017 I became part of the Divesoft team. I enjoy the variety: general software development, troubleshooting real hardware, and helping with the more complex support cases. \n\nAs for gear, I’ll recommend any sidemount wing, as long as you can clip a Liberty eCCR SM onto it. 
 If I’m not at my desk, you’ll probably find me somewhere near the water. Outside of diving (and anything involving water), I clear my head by rock climbing or doing anything that has to do with rocks. And when I want to switch off completely, I read Tom Clancy novels.\n","contact":"","images":[{"id":"1","image":{"mimetype":"image/jpeg","size":849525,"hash":"75b6fdc6f3083e7955d697f56ee8b22f884b545b","id":"cmlgfotcwlm140800kawiduut","filename":"hecko.jpg","category":"divesoft/","type":"image","alt":"photo of Jakub Hečko, Chief Technical Officer from Divesoft"}}],"equipment":[{"id":"1","title":"LIBERTY <light>LIGHT</light>","eshopUrl":{"url":"https://www.divesoft.com/en/ccr-liberty","mediaData":{"mimetype":"image/jpeg","size":50745,"hash":"6c22b8a5eba20aaf637c4d14496dc84fca8db4cd","id":"cjxc5i4lo079407760imjcn2n","filename":"sidemount-.jpg","category":"divesoft/","type":"image"}},"image":{"mimetype":"image/png","size":902116,"hash":"bcdd815c30b6f23dc503851747d0970a20d5b6aa","id":"cmo9uzcp90m9h08003z0wvkqs","filename":"render13.png","category":"divesoft/","type":"image","alt":"Liberty Light"}}],"activeTab":"1"},"id":"#2","type":"component","lock":false,"position":1},{"name":"JsonLD","data":{"jsonLD":"{\n  \"@context\": \"https://schema.org/\",\n  \"@type\": \"Person\",\n  \"@id\": \"https://www.divesoft.com/en/about-us/jakub-hecko#person\",\n  \"name\": \"Jakub Hečko\",\n  \"givenName\": \"Jakub\",\n  \"familyName\": \"Hečko\",\n  \"jobTitle\": \"Chief Technical Officer\",\n  \"knowsAbout\": [\n    \"IANTD CCR Trimix Diver\",\n    \"ASTD Technical Cave Diver\",\n    \"Software development\",\n    \"Hardware troubleshooting\",\n    \"Technical support\"\n  ],\n  \"worksFor\": {\n    \"@type\": \"Organization\",\n    \"@id\": \"https://www.divesoft.com/#organization\",\n    \"name\": \"Divesoft\",\n    \"url\": \"https://www.divesoft.com/\",\n    \"logo\": \"https://www.divesoft.com/assets/divesoft/images/logo.svg\"\n  },\n  \"url\": \"https://www.divesoft.com/en/about-us/jakub-hecko\",\n  \"image\": \"http://foxer360-media-library.s3.eu-central-1.amazonaws.com/divesoft/75b6fdc6f3083e7955d697f56ee8b22f884b545b_hecko.jpg\",\n  \"description\": \"Jakub Hečko joined Divesoft in 2017 as a Freedom diver and now works as Chief Technical Officer, contributing across software, hardware troubleshooting, and complex technical support.\",\n  \"mainEntityOfPage\": {\n    \"@type\": \"ProfilePage\",\n    \"@id\": \"https://www.divesoft.com/en/about-us/jakub-hecko#profile\",\n    \"headline\": \"Profil Jakuba Hečka\",\n    \"url\": \"https://www.divesoft.com/en/about-us/jakub-hecko\",\n    \"about\": {\n      \"@type\": \"Person\",\n      \"@id\": \"https://www.divesoft.com/en/about-us/jakub-hecko#person\"\n    }\n  }\n}"},"id":"#3","type":"component","lock":false,"position":2},{"name":"Footer","data":{"copyrights":"Copyright © 2019 Divesoft LLC All rights reserved.","facebookUrl":"","youtubeUrl":"","instagramUrl":"","contacts":"**Divesoft, s.r.o.** Hálkova 2495 413 01 Roudnice nad Labem Česká republika Tel.: +420 416 857 057 E-mail: [email protected]"},"id":"#1","type":"component","lock":false,"position":3}],"id":"root","idBuffer":"#4","lastCommit":"60e87f27-6571-4aff-88fe-083196d088e7"}},"annotations":[{"type":"id","generated":true,"id":"PageTranslation:cmdilhy9s0c8s0832dmjjmmzz.annotations.0","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cmdilhy9s0c8s0832dmjjmmzz.annotations.1","typename":"PageAnnotation"},{"type":"id","generated":true,"id":"PageTranslation:cmdilhy9s0c8s0832dmjjmmzz.annotations.2","typename":"PageAnnotation"}],"language":{"type":"id","generated":false,"id":"Language:cjv3kwvoj000u083611381c6o","typename":"Language"},"__typename":"PageTranslation"},"PageTranslation:cmdilhy9s0c8s0832dmjjmmzz.annotations.0":{"key":"title","value":"Jakub Hečko","__typename":"PageAnnotation"},"PageTranslation:cmdilhy9s0c8s0832dmjjmmzz.annotations.1":{"key":"perex","value":"","__typename":"PageAnnotation"},"PageTranslation:cmdilhy9s0c8s0832dmjjmmzz.annotations.2":{"key":"image","value":"null","__typename":"PageAnnotation"},"Page:cmdipepgt00xb08322to2saio":{"id":"cmdipepgt00xb08322to2saio","type":{"type":"id","generated":false,"id":"PageType:cjv3l213x004f08366hjufttp","typename":"PageType"},"tags":[],"translations({\"where\":{\"language\":{\"id\":\"cjv3kwvoj000u083611381c6o\"}}})":[{"type":"id","generated":false,"id":"PageTranslation:cmdipepix00xi0832mp22d5hu","typename":"PageTranslation"}],"__typename":"Page"},"PageTranslation:cmdipepix00xi0832mp22d5hu":{"id":"cmdipepix00xi0832mp22d5hu","name":"ECHO Quick reference","createdAt":"2025-07-25T10:54:08.312Z","content":{"type":"json","json":{"content":[{"name":"Header","data":{"products":[{"title":"Accessories","description":"Backplates, Consumables.

It cannot be used to analyze mixes containing other gases, including, for instance, mixes prepared using anything but pure gases or mixes in which air has been replaced with pure nitrogen (without atmospheric argon).\n\n* The physical and chemical principles of the sensors used do not guarantee that the sensors will be selectively sensitive to a specific gas (oxygen, helium); there are a number of gases to which the sensors respond. Therefore, the gas composition shown by the analyzer does not mean by itself that the real composition of the mix is equal to the displayed values. \n\n* The displayed mix composition is invalid unless the mixing technology ensures that there are no other gases present in the mix except air, pure oxygen and pure helium. \n\n* The analyzer is not a certified measuring instrument. The results of measuring are only informative and it is not possible to use such results where a certified measuring instrument is required. \n\n* When analyzing mixes in situations where the incorrect composition of the mixes could cause material damage, injury to health or threaten human health or life, for example in the case of breathing mixes for diving, the results of the analysis may not be used as confirmation of the correct mix composition. In these cases, the analyzer can only be used as an aid for increasing the probability that such incorrect mix composition will be detected before its use. \n\n* The correctness of the mix composition must be established by the technology used to prepare it. The correct preparation of breathing mixes for diving (nitrox – oxygen-enriched air, trimix – a mixture of air, oxygen and helium, heliox – a mixture of oxygen and helium) requires special knowledge and experience which is possible to gain, for example, through an appropriate course. A failure to apply such knowledge c

2an lead to an incorrect mix, even though the results of the analysis are seemingly correct. Such a situation can also be the result of a failure to take into account the influence of temperature and compressibility, an insufficient blending of the mix and other factors. \n\n* Please remember that the analyzer can be broken or damaged and that the oxygen sensor is by its nature subject to ageing and thus its properties deteriorate. Therefore always verify the measured data in another way, such as by precise preparation of the mix, another analytical method, etc. In addition, the measured value must be subject to critical assessment using a common-sense approach and if it differs from the allowable variation of mixing accuracy, it must be considered invalid.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#52","type":"component","lock":false,"position":8},{"name":"Divider","data":{"color":"darkGray"},"id":"#54","type":"component","lock":false,"position":9},{"name":"TextBlock","data":{"text":"### <span id=\"00.-ECHO-likes-to-breathe\">**00.

Measuring principle**</span>\n\n\nThe described measuring principle is valid only for mixes of air, oxygen and helium.  \n\nAn electrochemical sensor is used to determine the oxygen content. The voltage at the sensor’s output is proportional to the oxygen content in the analyzed mix. The sensor has a limited service life and the proportionality of the dependence of voltage on the oxygen content changes over time; therefore, it has to be regularly calibrated. It is possible to choose between single-point, two-point and three-point calibration. Single-point calibration is fast, especially if air is chosen as the calibrating mix. For greater accuracy of the measurement, two-point calibration is used with two different mixes, typically air and pure oxygen. For strongly hy

2poxic mixes, i.e. mixes containing less than approximately 15% oxygen, three-point calibration is recommended. In this case, the third calibration gas should be a gas with zero oxygen content, i.e. pure helium or argon.  \n\nHelium content is determined on the basis of measuring the speed of sound in the analyzed mix. The speed of sound depends on the content of helium and oxygen, and the temperature of the mix. The dependence of the speed of sound on pressure is small and can be disregarded under normal atmospheric pressure.  \n\nAt 0º C the speed of sound is approximately 970 m/s in pure helium, 330 m/s in air and 315 m/s in pure oxygen. Raising the temperature by one degree increases the speed of sound by 0.175 %. The speed of sound in the mix is described by a non-linear function of temperature, oxygen content and helium content.  \n\nThe content of helium is determined by measuring the speed of sound, temperature of the mix and the content of oxygen. When measuring the concentration of helium, it is therefore necessary to have the oxygen sensor correctly calibrated or to know the oxygen content and enter it into the instrument.  \n\nThe speed of sound is measured directly as the time it takes for an acoustic impulse to travel between two microphones. This measurement is performed alternately in both directions to make it possible to eliminate the influence of the gas flow-rate in the probe on the calculation. The acoustic impulses are heard as weak “clicks” from the probe in the helium-measuring mode.  \n\nGas is delivered to the analyzer from a sampler connected to the compressed-gas tank and the gas flow is controlled using a nozzle to provide the volume needed for the analysis.","textLarge":false,"imageOnRight":true,"image":{"recommendedSizes":{"width":"420","height":"280"}},"imageMobile":{"recommendedSizes":{"width":"750","height":"500"}}},"id":"#55","type":"component","lock":false,"position":16},{"name":"Divider","data":{"color":"darkGray"},"id":"#60","type":"component","lock":false,"position":17},{"name":"SectionDivider","data":{"title":"3.

Calibration of the oxygen sensor**</span>\n\nThe oxygen sensor’s properties change over time and it is therefore necessary to recalibrate it. We recommend that such calibration be performed at least once a month. ECHO analyzer has a built-in barometer sensor, which corrects itself. If you require the most precise results, calibrate the sensor before each measuring.\n\n**NOTE:** Solid state O2 sensor calibration interval is 6 months, or if value in ambient air significantly differ from expected - when accounted for humidity - see table at the end of this chapter.\n\nCalibration of the sensor is performed as either single-point or two-point or three-point. \n\nDuring **single-point calibration**, the content of oxygen in air, which is known and constant (20.95 %), is measured by the sensor. The calibration constant of the sensor is set so that the instrument displays 21.0 % (after rounding).\n\n**Two-point calibration** proceeds in the same manner as single-point calibration, but uses two calibration gases – pure oxygen and air. Two-point calibration is more arduous as it requires the use of oxygen. However, it provides more precise results during measuring.\n\n**Thee-point calibration** is recommended only for measuring hypoxic mixes, containing less than approximately 15 % oxygen. In this case, the third calibration gas should be a gas with zero oxygen content, i.e. pure helium or argon.\nThree-point calibration before measuring mixtures with a higher oxygen content can, on the contrary, lead to inaccurate measurements.\n\nThe values displayed on the device screen and the availability of advanced functions are limited.

The corresponding END is then calculated automatically.  \n•\tThe same logic applies to other parameters such as PO₂ limits, END, or gas density.\n\nConversely, if a specific gas composition is entered, the application calculates the usable depth range and the gas properties at the selected depth.\n________________________________________\n**Gas Mixing**  \nTo prepare a gas mixture, enter the existing gas in the cylinder at the bottom of the screen.
