Description

O2ptima CM

The most versatile tool for underwater exploration.

The simplicity of the O2ptima CM results in limitless possibilities of use. The O2ptima CM is fully compatible with whatever open-circuit system you’re currently diving: sidemount, back mounted doubles, or a single tank. The chest-mounted design easily attaches to almost any harness using four bolt snaps. This rebreather can be quickly added or removed for any mission. Add it to your single tank rig for a deep ocean dive and remove it later for a shallow open circuit reef dive. Use it in place of a stage bottle to greatly extend your penetration distance in an overhead environment. Remove and stage it underwater for later decompression or to navigate tight restrictions… The possibilities are endless and the O2ptima CM has been used for cutting edge exploration and world class expeditions all over the globe.

The design parameters for the O2ptima CM were simple and included:

  • Keep the breathing loop as short as possible.
  • Use state-of-the-art electronics.
  • Be fully compatible with the ExtendAir CO2 Absorbent Cartridge.

All of these parameters were achieved in a rugged and durable package with the smallest profile possible.

Dive Rite has committed to ensuring that it is one of the most reliable, capable, and high performing rebreathers on the market. The O2ptima design continues to evolve as units are tested, refinements are made, and new technology becomes available. We are certain that this unit will provide you with many unforgettable hours exploring your underwater world.

The O2ptima CM breathing loop is one of the shortest of any rebreather on the market. 12 inch (30 cm) loop hoses come standard with 10 inch (25 cm) hoses available for an improved fit on smaller divers. The hose diameter and lengths have been specifically chosen to provide the best balance of comfort and low work of breathing.

The O2ptima CM uses two integrated, chest-mounted counterlungs with 6.4 liters of total loop volume. This choice of position keeps them as close as possible to the diver’s lung centroid. This design provides for incredibly low work of breathing in a variety of diver orientations. There is an internal water trap located at the bottom of the exhalation counterlung, which makes dewatering the loop easy.

The outer bag of the counterlung contains a zippered storage pouch on the front for stowing accessories. Under this pouch is an attached line cutter sheath.

The O2ptima CM comes standard with a Dive Rite DSV. This DSV has been completely redesigned from the ground up so that it has an exceptionally low work of breathing in the most compact design possible. Two high performance mushroom valves are utilized to ensure one way gas travel.
