Dive Rite O2ptima CCR

About the Course

First produced in late 2005, the O2ptima CCR has been a leader in the rebreather market for almost two decades. The O2ptima features a rear-mounted counterlung design that greatly reduces the diver’s work of breathing. The breathing loop was kept as short as possible by utilizing a horizontally-mounted scrubber canister positioned behind the diver’s head. This also contributes to maintaining the lowest possible work of breathing, which increases diver comfort and reduces fatigue. Mounting the scrubber canister at the highest point of the loop has the additional advantage of reducing the likelihood of water entering the scrubber. This, combined with the use of the ExtendAir CO2 Absorbent Cartridge, greatly reduces the likelihood of a painful “caustic cocktail.” These features are the reason why the O2ptima CCR has been used for cutting edge exploration and world class expeditions all over the globe for years.
