The O2ptima’s design includes minimal risk of a caustic cocktail. Two water traps in the loop along with horizontal, behind-the-head positioning of the scrubber canister create a difficult path for water to travel. An even greater advantage is gained by using Micropore Extend Air scrubber cartridges, which do not contain dust. It is the dust that reacts quickly with water to form a caustic cocktail.

The O2ptima delivers excellent work-of-breathing that allows divers faced with strong flow or ripping current to breathe comfortably. Over-the-shoulder counterlungs  along with the scrubber positioned behind the head means gas has less distance to travel, so the diver does not have to work as hard to “pull” gas through the loop. This also allows the O2ptima to have smaller diameter loop hoses, which minimizes jaw fatigue.

A stainless steel frame and Rhinotec 600-denier polyester cover protects the O2ptima from tight cave squeezes and rolling boats. Hoses, regulators and tanks are kept neatly streamlined and away from potential snags inside a wreck or cave.

Now featuring an all new rear-mounted counterlung design utilizing Divesoft’s multi-function BOV, the O2ptima 2018 CCR has become one of the most streamlined CCR packages on the market. With its horizontal scrubber, the O2ptima boasts an extremely short breathing loop improving performance, safety, and diver comfort. The O2ptima CCR is powered by Shearwater electronics. Utilizing Shearwater’s DiveCan technology, the O2ptima comes standard with a Petrel 2 controller and an independent Heads-up Display (HUD). For buoyancy control, the O2ptima includes the divers choice of the Dive Rite TransPac or TransPlate harness along with their CCR XT wing specifically designed for rebreathers. The O2ptima includes { 20 cuft | 3L } cylinders and valves, but also accepts a very wide range of cylinder sizes from aluminum 13’s (2L) to steel 27’s (4L). Less the cylinders, the entire unit can be carry-on luggage for most airlines.
