New Helitrox Course!


I’m happy to announce an exciting new course option: Helitrox. Helitrox is a breathing gas with up to 20% helium. Since helium is virtually non-narcotic under pressure, adding it to our gas allows us to manage or nitrogen narcosis exposure.

I’m offering Helitrox certification as part of the Adv. Nitrox/Decompression Procedures program. I think Helitrox adds a vital, missing piece of the Adv. Nitrox/Deco Procedures course when taught in the Great Lakes. Adv. Nitrox/Deco Procedures trains you to conduct dives requiring staged decompression to a maximum depth of 150′ and use oxygen-rich mixtures as decompression gasses. But we were limited to using air or nitrox as bottom gas. However, using air in the Great Lakes at 150′ is not always a good choice. The cold water and limited visibility can exacerbate nitrogen narcosis even as “shallow” as 150′. With the addition of the Helitrox certification, we can add up to 20% helium to our bottom gas which gives us the equivalent narcotic dose as breathing air at 100′.

I am forming an Adv. Nitrox/Deco Procedures/Helitrox course for September. Contact me (rick@greatlakestechdiving.com) quickly if you’re interested or have questions.
