Advanced Nitrox Diver
Enriched-air mixes up to 100% oxygen — the foundation of mix diving.
About The Course
Advanced Nitrox takes you beyond the 40% recreational nitrox ceiling to enriched-air blends all the way to pure oxygen, and teaches you to carry and switch to accelerated-decompression gases.
It is the gas-management half of technical diving and is almost always trained alongside Decompression Procedures as a combined deco package — the moment recreational diving becomes technical.
