Enriched Air Nitrox Diver

The Course


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




If you’re an Open Water Diver or equivalent who is at least 12 years old, you can enroll in the Enriched Air Diver Specialty course.

The Learning

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 application session you’ll:

  • Discuss managing oxygen exposure.

  • Practice analyzing oxygen content in your scuba tank.

  • Learn to set and use your dive computer for diving with enriched air nitrox.


$180 per person 

Course tuition includes:

  • PADI Enriched Air Diver eLearning

  • Practical application session with one of our professional instructors

  • Certification processing

  • Certification card

Once you complete the eLearning component of the course, stop by or give us a call at 214-227-2494 to register for a practical application session.

Student Agreement: By registering for the Enriched Air Nitrox Diver Course, you indicate that you have read and agree to the course policies, terms and conditions.


The Gear


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 recognizing special cylinder decals. Your instructor will explain other equipment you may need to enjoy enriched air diving.

The Next Step

Your PADI Enriched Air Diver certification can be credited toward your Advanced Open Water Diver and Master Scuba Diver certifications. Stop by or give us a call for the details.

You may want to expand your diving opportunities even more with the PADI Advanced Open Water Diver course, Rescue Diver course, or another specialty course. Ask your Scuba Frisco instructor or divemaster about the possibilities.
