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.

FAQs
What makes the O2ptima CM different from other rebreathers?
The O2ptima CM is a chest-mounted, fully electronically controlled closed-circuit rebreather (eCCR), known for its versatility and compact design. It easily attaches to almost any harness and is compatible with sidemount, back-mounted doubles, or single-tank systems. Its modular design allows it to be added or removed during dives for various applications, such as deep ocean dives or overhead environment penetrations.
How long do the consumables last?
The main consumable for the O2ptima CM is the CO2 absorbent. Depending on the type (granular or cartridge), the duration can range between 4-6 hours of dive time under typical conditions. Battery life for the electronics ranges between 30-50 hours.
What type of training is required to use the O2ptima CM?
All rebreathers, including the O2ptima CM, require specific training before they can be used. You must be certified on the specific model to operate it safely. See Dive Rite's O2ptima Instructor Listing to find an instructor.
What are the routine maintenance requirements?
Routine maintenance for the O2ptima CM involves replacing the galvanic oxygen sensors annually and a full service every two years or 100 dives.
Can I switch between granular and cartridge CO2 absorbents?
Yes, the O2ptima CM is designed to accommodate both Micropore ExtendAir cartridges and loose granular absorbents. This versatility allows divers to choose the option that best suits their diving conditions and preferences.
Is the O2ptima CM suitable for travel?
Weighing only 14.4 lbs without the oxygen cylinder or absorbent material, the O2ptima CM is compact and ideal for travel. Its chest-mounted design allows it to be rolled up and stored in a carry-on, making it easy to transport.
