TDI Advanced Nitrox/Helitrox

Ready to Dive Deeper, Clearer, and Longer?

Are your no-decompression limits (NDLs) constantly cutting your dives short? Do you hit the surface wishing you could stay down just a little longer on that incredible wreck or reef?

As a sport diver, planned decompression and helium based mixes aren’t part of the standard toolkit but they’re the game-changer that lets you safely extend bottom time, reduce narcosis, and breathe easier at depth.

The TDI Advanced Nitrox/Helitrox Course is your ticket to true technical diving mastery.

Learn to plan and execute staged decompression dives using the most effective gas choices: enriched nitrox for accelerated deco and helium based mixes (Helitrox) to slash gas density, dramatically reduce nitrogen narcosis, and keep your head clear even at 45 metres.

This course, combined with TDI Decompression Procedures, forms the unbreakable foundation for every advanced technical path ahead, deeper trimix dives, cave exploration, wreck penetration, and beyond.

After these two courses and a bit of real world experience, the stage is set for you to unlock the full potential of technical diving.

Stop leaving bottom time behind. Breathe smarter. Dive deeper. Explore more.

Enroll in TDI Advanced Nitrox/Helitrox today. The deeper you go, the more the ocean reveals.
