About the course

Extend your bottom time, shorten your surface intervals and dive deeper on repetitive 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.

  • Instructors, divemasters and dive shop staff are not physicians and should not be asked for medical advice; only medical professionals can give medical clearance to dive.
  • If you (or your physician) have questions about medical fitness to dive, contact the experts at Divers Alert Network (DAN).
