EANx Diver

EANx Diver (aka Nitrox)


Do you want to extend your bottom time, lessen your surface interval, and maximize every dive? Become a NAUI Enriched Air Nitrox diver! This course may be taught as a stand alone program or may be combined with other classes such as NAUI Scuba Diver or NAUI Advanced Diver.

This class can be taken in two forms:

  • Private Session
  • NAUI E-Learning

If you have any questions, please feel free to contact us! Of course we have our scheduled classes and checkout dives, but custom options are also available if these don’t fit your schedule. We offer weeknight classes, private classes at your pace and location, and you can do your checkout on our exotic dive trips.


During this course, you will learn how to choose the proper blend of Nitrox for your dive profile, determine maximum depth limits for your Nitrox mixture, analyze your breathing mixture, and plan and safely execute each dive. Your instructor will teach you about 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.

After your exam, you can qualify for the Nitrox recognition card, or go ahead and complete two dives to receive your Nitrox Diver certification card. And, your NAUI instructor can integrate your Nitrox course into your Scuba Diver course!

Available as private traditional class or using NAUI E-Learning “study-at-home”.
