O2PTIMA CM – COMPACT, EXPEDITION-READY REBREATHER ENGINEERED FOR SERIOUS TECHNICAL DIVING

The Dive Rite O2ptima CM is a next-generation, chest-mounted rebreather built for divers who demand maximum reliability, mobility, and mission flexibility in extreme environments. Its compact design shifts the breathing loop off the back and onto the chest, freeing the diver to streamline their profile, carry additional cylinders, or navigate restrictions with confidence. The result is a powerful, expedition-grade CCR system that excels in caves, deep wrecks, and advanced exploration profiles.
The CM’s electronic control system delivers precise oxygen management with redundant monitoring, giving divers stable setpoints and consistent loop performance. The scrubber design promotes efficient CO2 absorption while maintaining low work-of-breathing across depth ranges. Quick-disconnect components and accessible mounting points make field servicing fast and intuitive—an essential advantage for expedition teams operating remote or multi-day dives.
Built around rugged materials and proven engineering, the O2ptima CM integrates seamlessly with sidemount or back-mount bailout configurations. Its modular mounting and compact footprint allow divers to tailor their rig for penetration diving, scootering, or high-capacity decompression. For technical divers seeking a reliable, travel-friendly CCR with exceptional versatility, the CM sets a new benchmark.
