The O2ptima is an electronically controlled closed circuit rebreather (eCCR). When we created the O2ptima the design parameters were simple; keep the breathing loop as short as possible, use state of the art proven electronics, and be able to use the MicroPore Extendair cartridge without extra o-rings or adapters.
In the end, we were able to achieve these goals while making the O2p-tima one of the smallest rebreathers suitable for cave exploration. The fact it was designed for cave exploration means it has redundancy options suited for remote environments. We understand one size doesn’t fit all, so in addition to standard features there are a number of options to ensure a proper fit for the person and mission
