Enriched air, also known as Nitrox is the favourite gas amongst deep divers: By adding oxygen to the breathing gas and reducing the nitrogen load in your body, you gain longer bottom times. A lower nitrogen load is especially desirable if you do several dives within one day for example on a liveaboard.

You gain the biggest benefits from this course when combined with the Deep Specialty. The nitrox course is land-based, and as such does not include dives unless combined with another course or fun dives. On this course you will learn to use and analyse enriched air as a breathing gas, to plan your dive and dive your plan with nitrox, and understand how nitrox affects you beneath the surface.
