My Thoughts on the JJ-CCR

The JJ-CCR is a rebreather which follows the KISS principle of  "Keep it simple."  This rebreather works well for a regular sports diver who is a technology enthusiast, as well as more complicated Trimix dives.  The largest operational areas in my opinion is it's use for wreck diving and cave diving.

The JJ has a Can-Bus system and monitors the sensors. If the deviation of the individual sensor values ​​is too great, they are colored in color on the handset. Furthermore, the JJ has an HUD, where the diver can read his PPO2 via a flashing line.  As with any ECCR, the JJ also has a solonoid, which feeds the oxygen to the desired PO2, which is usually between 0.7-1.4 PP02.  The JJ can also be controlled manually with manual add buttons.  The JJ has standard a Shearwater Petrel 2 as a controller to the HUD can also be connected to a Shearwater NERD.

The JJ-CCR has a very sturdy construction, this is reflected again by the aluminum tube stand.  In addition, the device has two radially sealed O-rings on separable screw connections, as well as the central control unit in the head of the unit. The breathing comfort is realized at the JJ because of the counterlungs.  With the back mounted counterlungs, which is more natural for breathing, it makes the work of breathing easier than other rebreathers.   The JJ is known for its robustness and reliability, the CE rating allows you to dive with the device in depths down to - 100m, as well as the above mentioned areas of application, so the JJ is for me an all-rounder which defies any challenge.
