Course Overview
The PADI Enriched Air (Nitrox) Diver course is the most popular PADI specialty worldwide, and for good reason. By diving with enriched air—which contains more oxygen and less nitrogen than standard air—you can safely extend your no-decompression limits. This means more time underwater, especially on repetitive dives! Many divers also report feeling less tired after diving with Nitrox. If you love staying down longer and getting back in the water sooner, this is the course for you.
