Dive Rite Rebreathers - Optima FX
The O2ptima FX is a fully closed circuit, constant PO2, electronically-driven rebreather with built-in decompression ability. Unique in the rebreather marketplace, the O2ptima is specifically designed for the rigors of cave diving where immediate surfacing is not possible. The resulting features are also highly desirable for wreck and deep ocean divers.
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 FX delivers excellent work-of-breathing that allows divers faced with strong flow or ripping current to breathe comfortably. Over-the-shoulder counter lungs 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 high impact 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.
