Enriched Air Nitrox

This specialty allows you to purchase and breathe Enriched Air Nitrox (EAN), a mix of breathing gas with a higher concentration of Oxygen than air. This course allows you to use mixes with up to 40% oxygen. When you use Nitrox, you cannot go as deep due to physiology, physics, and partial pressures. You can, however, extend your dive time and find that you are far less fatigued after diving. Often nicknamed “nitrox”, “EAN”, “enriched air”, or “geezer gas”.
