This course gives the technical or extended range diver the ability to increase their safety and enjoyment of dives in the 40m+ range by the addition of helium to their breathing mix.


The course is designed to be run in conjunction with the Technical Nitrox course as a continuous program, but can also be run as a top up to the Technical Nitrox course for divers already qualified at that level. The course covers the dive planning, physiology and skills to utilise the safety advantage of using Helium in the breathing mixture whilst at depth.
