The JJ-CCR rebreather has been called ‘the 4 x 4 of the rebreather community’ which in many ways is the perfect description as it is built for all types of terrain and can be adapted to handle the most demanding adventures. The JJ-CCR demands a skilled diver fully aware of the pros and cons of technical rebreathers and was never intended for the sports diving market, it was engineered by professional wreck divers who needed a solid tool to do the job in the deep, dark, and cold waters of the Baltic Sea...

The JJ-CCR has an industry low work of breathing. With its back mounted counter lungs that follow the contours of your shoulders, it will help you to keep a smooth and comfortable breathing pattern. T-pieces milled out of Delrin connect to heavy duty breathing hoses that end in a sturdy DSV (Dive Surface Valve).  The breathing loop has an integrated ADV (Automatic Diluent Valve)...

The standard scrubber unit on the JJ-CCR is an axial scrubber. It holds 2,3 kg sodalime (sofnolime 797). The scrubber unit is easy to lift out of the canister as the attached lid has a lifting handle on top.  The scrubber is attached to the lid by a heavy duty thread.

​

The construction of the scrubber, lid and canister makes re-packing of scrubber as well as surface interval maintenance an easy task!...

The canister is made from hard anodized aluminum and has 4 welded consoles for the attachment of tanks and/or light canisters, etc. The canister has two cylinders that can be filled with compensating weights if needed. The lift handle that is located on top of these cylinders can be lowered to minimize the height of the construction.

The stand which is bolted in the bottom of the canister is made from stainless steel and gives stability and comfort to the user while handling the rebreather on land...

The JJ-CCR is equipped with a state of the art electronics package.  It has a redundant power supply with one battery for the controller, one battery for the HUD and two parallel batteries for the solenoid.  None of the batteries are integrated into the breathing loop.  It has a DiveCAN® communication interface for robust data transmission and easy upgrades, disassembly and repairs.  The JJ-CCR has wet contacts for automatic turn-on...

The JJ-CCR is equipped with a fully adjustable harness designed specifically for the JJ-CCR. The harness is padded in the shoulder and chest area which provides the user with great comfort.  The harness is designed with numerous equipment D-rings so that the user can configure equipment according to task...

The JJ-CCR is a versatile rebreather built for every dive you have in mind. The canister is equipped with 4 sturdy consoles, designed and placed so that diver and team can configure their JJ-CCRs for maximum exploration output...

The JJ-CCR is equipped with excellent hardware for maximum performance and reliability; APEKS US4 first stages and Mi-Flex hoses, machined T-pieces, ADV housing and manual inflation valves to name a few. All components are there for a reason and built to withstand extreme conditions and environments... 

Factory options for the JJ-CCR include the X-tended Range Canister (XRC) and the head cover.

​

The XRC is only for extended range diving and comes complete with stand, handle and radial scrubber.  The canister has been extended in length by 50mm and the stand has been shortened by the same length so the overall size of the unit remains the same.

​

The head cover offers protection of the rebreather head and its vital components during travel...
