Optima Rebreather
O2ptima CM
Manufacturer Dive Rite
Building on the success of the O2ptima CM, the 2nd Generation O2ptima CM streamlines the unit into as compact a package as possible. Over six inches (15cm) have been removed from the top to bottom distance, allowing divers of all shapes and sizes to enjoy the O2ptima CM in every environment, from a single tank liveaboard trip to cutting edge global expeditions.
The loop was reimagined to streamline the gas path and further improve work of breathing. 3d counterlungs minimize gas turbulence and reduce the overall profile while maintaining a 6.5 liter loop volume. 35 degree fittings have replaced 90 degree elbows, creating a more direct gas path through the unit. Wider bore loop hoses with increased corrugation allow greater flexibility and less restriction on gas flow. All of these elements combine to bring work of breathing down to nearly 1 joule in a laboratory testing environment.
The O2ptima CM is available with either a Petrel 3 or Nerd controller in Black SuperFabric, or red, blue, OD green, pink or white Cordura.
Made in the USA.
*Due to the reduced length of the 2nd generation, a scooter ring is not necessary for most divers.
*The skid plate is an optional accessory recommended for those diving in tight spaces.
