The TDI Helitrox Diver course is an alternative to the traditional TDI Decompression Procedures course, but can also be taught as an upgrade for divers who have already gained their Decompression Procedures certification. As well as covering all of the in water content and theory of the Decompression Procedures course, students will gain the additional theory and dive planning considerations needed when planning dives using Helium, and conduct at least two dives using Helitrox to a maximum depth of 45m.

What Will You Learn?

There are many benefits to using Helium as a breathing gas, as well as a few additional considerations that need to be taken into account. This course will explain why deep divers use Helium and teach you to plan and execute decompression dives utilising up to 35% Helium in your primary gas mix.

The majority of our Helitrox Diver courses are run in combination with the TDI Advanced Nitrox course, so please check out our Combined Courses page for more details, along with upcoming course dates.
