Enriched Air Nitrox

Do your no-decompression limits stop you from staying under as long as you would like? Then welcome to one of our most popular specialties – the Enriched Air Nitrox course. Diving with enriched air nitrox lets you safely extend your no stop time beyond the no decompression limits for air.

Diving with enriched air means more time underwater – but you need to be certified as an Enriched Air Diver to get enriched air fills. Whether you’re into underwater photography or wreck diving, the Enriched Air Nitrox course helps you get more out of diving by giving you more time underwater.

The course covers the physiology of oxygen and nitrogen; advantages, disadvantages, and risks of nitrox; oxygen toxicity; hazards and precautions of handling oxygen; the concept of Equivalent Air Depth; use of EANx with standard Air Dive Tables; common gas mixing procedures; and more
