Nitrox Enriched Air

Nitrox Enriched Air Specialty

The Nitrox Enriched Air Specialty is the most popular specialty course in the world.
Reason is that diving with enriched air allows you to stay longer under water. This is due to the lower Nitrogen content, allowing you longer bottom times, especially on repetitive dives.

Besides staying longer under water you can also get back into the water faster, which sounds attractive if you would like to make a 2nd deep dive. 

This course can be easily combined with any other specialties such as Deep 40, Wreck Diver, or Digital under water Photography.
