The ever-popular JJ CCR can be seen wherever rebreather divers are. In many ways, it’s somewhat like the 4X4 of the rebreather world. The unit is machined out of solid anodized alloy, and comes with an axial scrubber as standard. When your diving progresses in line with your skill level, there is an option to upgrade the scrubber to a radial model.
You can equip the JJ with up to 4 tanks of 2 to 12 liters of different gas mixtures and it comes with APEKS first stages. A CE rating means this unit is certified for safety by a third-party agency.
You can find more info on the JJ CCR’s specs and features here. Note that there are differences between the CE model and the International model in the manual diluent valve.
Our Overall Review
Things we like:
-
Plenty of options for after-market add ons and additions -
Common unit so easier to find service persons and centers
-
Stands well by itself
-
Three lights on the HUD indicate each cell
-
A good unit for beginner CCR divers
Things we don't like:
The JJ is BIG, not ideal for travel but that said, plenty of divers still find ways around this- Only a back-mounted counter lung option, not customizable like some units
