Dive Longer and Safer with Nitrox!

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.

Learn why nitrox allows you to make longer dives and how to dive nitrox safely through online independent study. Meet with your PADI Instructor for hands-on practical exercises, then make two (optional) dives.

What you can expect to learn

  • Dive with Nitrox
  • Use an oxygen air analyzer
  • Set your dive computer

Course Equipment Requirements

If you do not own a set of scuba equipment, and you would like to make the two optional dives, you will need to rent gear.

If you own scuba gear, confirm it can be used with nitrox (don’t worry, most modern dive equipment is compatible). If you don’t have the manuals that came with your equipment, your PADI Dive Shop or Instructor can help.

Only certain scuba tanks can be filled with enriched air (you’ll learn more about this in the course). Your PADI Dive Shop will provide dedicated nitrox cylinders for your enriched air dives. Your instructor will also provide an oxygen analyzer.
