NAUI Enriched Air Nitrox Diver Course

Extend your bottom time, reduce nitrogen exposure, and enhance your diving experience with the NAUI Enriched Air Nitrox Diver Certification Course.

Enriched Air Nitrox (EANx) is a breathing gas mixture containing a higher percentage of oxygen and less nitrogen than regular air. By reducing the amount of nitrogen absorbed by your body during a dive, Nitrox allows divers to enjoy longer no-decompression limits on many dives and may help reduce post-dive fatigue.

Nitrox has become the most popular specialty certification among recreational divers and is widely available at dive destinations around the world. Whether you enjoy reef diving, wreck diving, underwater photography, or multiple dives in a single day, Nitrox can help you maximize your underwater adventures.

Benefits of Diving with Nitrox

• Longer no-decompression dive times

• Reduced nitrogen absorption during dives

• More conservative diving profiles

• Potentially less post-dive fatigue

• Increased safety margin when diving within air dive tables

• Ideal for repetitive diving and dive vacations
