A JJ-CCR Rebreather is designed and built to exceed the expectations of skilled exploration divers. The JJ-CCR has been called "the 4 x 4 of the Rebreather community" which is in many ways a consistent description as it is built to handle all types of harsch environments and can be adapted to handle the most demanding adventures.
This is the new JJ-CCR CE-Edition, launched in August 2014. Equipped with a Petrel computer, a digital HUD, manual supplemental O2 and diluent valves with the option of feeding in external gases. The rebreather comes ready to fly right out of the box. Fill it with gas and sofnolime and serious adventures is just about to begin. The philosophy behind the JJ-CCR is to keep it simple; K.I.S.S. simple... The JJ-CCR has a robust construction with minimalistic detail work. It gives the diver a versatile rebreather, still very easy to handle as well as to deal with before and after operations. It is a rebreather built by divers and diving engineers. All components has a purpose and every detail can be justified in order to perform as a system helping the diver to reach his goals. The JJ-CCR is equipped with state of the art electronics and computing but it will still demand a skilled diver fully aware of the Pro´s and Con´s of technical rebreathers.
The JJ-CCR is an extremely versatile rebreather which is helping JJ-CCR divers to reach fantastic places.

On board gas duration
|
|
Oxygen: The on board oxygen supply will last 252 minutes, if the diver consumes
1.78 liter of oxygen per minute.
3 liter x 200 bar = 600 liter - 25% reserve = 450 liter
Diluent: The duration depends on the depth and activity of the diver.
3 liter x 200 bar = 600 liter
