The Enriched Air/Nitrox Diver course is the most popular specialty scuba course in the world!  Why? Because scuba diving with enriched air nitrox gives you more no-decompression time, especially on repetitive scuba dives. If staying down longer, getting back in the water sooner and feeling more rested sounds appealing, then don’t hesitate to become an enriched air/nitrox diver.

This is a 2 Phase Certification Course:

PHASE 1: Independent Study / eLearning

PHASE 2: Classroom with an Instructor



You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical training session, and two simulated scuba dives, you’ll:

  • Discuss managing oxygen exposure.
  • Practice analyzing oxygen content in your scuba tank.
  • Dive planning enriched air/nitrox scenarios
  • Set your dive computer for diving with enriched air nitrox.


Most modern scuba equipment and dive computers can be used with enriched air, but your Instructor will let you know if your gear meets manufacturer recommendations and local requirements. However, scuba tanks must meet oxygen service standards and be dedicated for use with enriched air. You’ll practice using oxygen analyzers and recognize special cylinder decals.
