The FLEX2 CCR, designed and built by iQsub and distributed by SubGravity, brings the proven X-CCR canister, scrubber, and head technology into a true sidemount rebreather. The standard unit includes a radial scrubber with up to 4.5 hours of runtime, the SM BOV Neo (or SM DSV) bailout valve, a removable O2 cell cartridge, Click-Lock keyed connections on every breathing hose and counterlung, Manual Addition Valves (MAVs) for both O2 and diluent, an Automatic Diluent Valve (ADV), Shearwater DiveCAN Petrel 3 controller, Shearwater HUD, oxygen first stage regulator, and three O2 cells as standard equipment.
The electronics package consists of the world-renowned Shearwater controller (Petrel 3 handset, with NERD 2 available as an option), which interacts with the Shearwater SOLO control board residing in the head of the unit. The two independent batteries are completely external to the breathing loop, sealed in their own compartments on either side of the head.
Configuration flexibility is the core of the FLEX2 design. Run it with two on-board cylinders, an oxygen-only on-board cylinder, or no on-board cylinders at all. Your gas configuration adapts to the dive instead of the other way around.
