Enriched Air Nitrox

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.


Minimum age: 12

Course prerequisite: enrollment in Open Water Diver

Divers 12 or older can earn a PADI Enriched Air Diver certification as part of their PADI Open Water Diver course. Ask your instructor for more information.


This course requires both knowledge development and in-person training for certification. 

  • When you purchase the PADI eLearning course from our website, the cost covers the knowledge development portion only.
  • There is an additional cost to complete your practical training with a PADI Instructor. Please contact your PADI Dive Center or Resort for pricing. 

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.
