Suunto HelO2 is the first dive computer from Suunto with full mixed gas capability. It is rated to 120 m/393 ft and incorporates the new Suunto Technical RGBM algorithm. Based on the RGBM algorithm developed by Dr. Bruce Wienke, widely recognized decompression scientist, the Suunto Technical RGMB algorithm extends decompression flexibility into the world of technical diving.

The algorithm introduces helium tissue groups in the decompression model to enable trimix diving, as well as diving on air and nitrox. It allows eight gases to be programmed as primary or secondary gases, and enables oxygen content of 8-100%, and helium content of 0-92%. For the technical diver, the great benefit of the algorithm is that it provides more flexibility and reduces task load when decompressing by removing the need to constantly monitor a slate and watch.
