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% to 100%, and a helium content of 0% to 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.
Suunto HelO2 multi-gas Dive Planner €“ part of the updated Suunto Dive Manager PC software €“ is designed to simplify the planning of dive profiles, gases, and back-up plans. The easy-to-use graphical planner allows you to try variations of depth, time, gases, and partial pressures without having to continually recalculate. The planner calculates all changes instantly and presents the results on an easy-to-read graph.
When ready, you can simply transfer information relating to planned gases, and other dive-critical data, from the PC to your dive computer with the included USB cable €“ removing the need to copy all the calculations onto a slate. The dive planner also gives you gas mixing instructions for your planned dive, which you can print out and take to a dive shop if you're not mixing yourself.
The Suunto Multi-gas Dive Planner enables you to plan dive series based on your actual dive profiles €“ not planned dive profiles €“ making the plans for later dives in the series more accurate. The planner also allows you to compare the planned dive and the actual dive by supporting the analysis of up to eight gases. This also helps you pinpoint elements of both your planning and diving that may need some fine-tuning.
