Enriched Air Nitrox (EANx) Diver

Want to stay underwater longer and explore more while decreasing your interval between dives? Become a NAUI Enriched Air Nitrox diver! This course will teach you how to use Nitrox, a type of breathing gas that contains more oxygen than regular air. This allows you to extend your bottom time and lessen your surface interval, so you can maximize every dive. The course can be taken as a stand-alone program or combined with other NAUI training programs, such as NAUI Scuba Diver or NAUI Advanced Diver.

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!
