Want to dive deeper, think clearer, and stay sharper underwater? The TDI Helitrox Diver course at Stuart Scuba is an exciting step into technical diving for divers who want more depth, more control, and a safer, more refined deep diving experience.

Helitrox is a powerful gas blend that uses helium to reduce nitrogen narcosis and improve mental clarity on deeper dives. This course teaches you how to plan and execute staged decompression dives using helium and nitrox, allowing you to dive up to 150 feet / 45 metres with greater awareness, improved gas strategy, and stronger technical skills.

For divers who want more bottom time without feeling foggy or fatigued, Helitrox can be a game changer. Whether your passion is spearfishing, deep reef hunting, wreck exploration, or preparing for more advanced technical diving, this course gives you real-world decompression training and a strong foundation for the next level.

At Stuart Scuba, our goal is to help divers build confidence, precision, and safety through skill-based training that works in real diving conditions. The TDI Helitrox Diver course is ideal for divers who are curious about technical diving but are not quite ready for full Trimix training just yet.
