The EANx Diver course enables the diver to dive with enriched air / Nitrox up to 40% oxygen. This allows you to extend the no-stop time for longer dives.
Enriched air, also known as nitrox or EANx, contains less nitrogen than regular air.
Breathing less nitrogen means you can enjoy longer dives and shorter surface intervals. No wonder Enriched Air Diver is the most popular PADI® specialty.
