Certain areas of the world provide spectacular dives at depths deeper than 39 metres but you may not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas, and with a maximum depth of 55 metres, so you don’t have to miss those dives! The TDI Extended Range Diver Course provides the training and experience necessary including proper techniques, equipment requirements, and hazards of deep air diving, to competently utilize air for dives up to 55 metres/180 feet that require staged decompression, using nitrox mixtures or oxygen during decompression.

Why upgrade to Helitrox? 

While you can still do a course to certify you to 55m on air (we even offer it), the diving community has generally shunned this practice as the availability and acceptance of trimix has become almost universal. Adding some helium to your bottom mix lowers your Equivalent Narcotic Depth (END) which reduces the amount of Nitrogen Narcosis you experience at a given depth. This, in turn, increases your safety as your reaction times, situational awareness, decision-making ability, and cognitive ability are less affected. The other benefit of a little helium is that it also lowers your gas density, making it easier and more efficient to breathe at depth. If you're in a cave environment and want to dive below 40m, then Trimix is mandatory by most training agencies worldwide.
