PADI Enriched Air (Nitrox) Diver
The PADI Enriched Air (Nitrox) Diver course is one of the most popular and useful scuba specialities, designed to extend your no-decompression limits and reduce surface interval times.
By learning to dive with enriched air nitrox (a breathing gas with a higher oxygen content than standard air), you can enjoy longer dives, shorter surface intervals, and a more relaxed dive profile, particularly when making repetitive dives.
This course focuses on planning, awareness, and discipline, making it a natural next step for divers looking to increase efficiency and comfort underwater.
