DiveRite Rebreather O2ptima CM

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. Made in the USA.
