Suunto HelO2 is an advanced mixed-gas dive computer for divers who use multiple gases such as trimix, nitrox, and oxygen to go deeper for longer. Featuring the Suunto Technical RGBM algorithm and a Multi-gas Dive Planner, the device is designed to make your whole technical diving experience simpler, faster, and more flexible.
Rated to 120 m/393 ft and with full mixed-gas capability, Suunto HelO2 incorporates the Suunto Technical RGBM algorithm. The algorithm extends decompression flexibility into the world of technical diving by allowing continuous decompression.
The algorithm introduces helium tissue groups into the decompression model to enable trimix diving, as well as diving on air and nitrox. It allows you to program eight gases as primary or secondary gases, and enables an oxygen content of 8-100%, and a helium content of 0-92%. In addition to increasing decompression flexibility, the algorithm also reduces your decompression task load by removing the need to constantly monitor a slate and watch.
