Course Description

The Enriched Air Diver course is one of the most popular specialty scuba courses because scuba diving with enriched air Nitrox gives you more no-decompression/bottom time especially on repetitive scuba dives. If staying underwater longer and getting back in the water sooner sounds appealing, then don’t hesitate to become an enriched air diver.

Learning Environment (eLearning)

For simplicity TSC conducts the Enriched Air/Nitrox course online as an eLearning course. This means students can sign up for the Enriched Air course whenever they want and complete the academic component in their own time. Once the eLearning component is completed students will need to come into the TSC store located downtown Toronto and complete some paperwork and learn how to analyze enriched air tanks using an O2 analyzer.


If you’re an Open Water Diver who is at least 12 years old, you can enrol in the Enriched Air Diver Specialty course. Note that in some regions the minimum age is older than 12.

What You Will Learn

Students will learn why diving with air that has higher oxygen and lower nitrogen content provides more bottom time, along with enriched air equipment considerations. During a practical session students will:

  • Discuss managing oxygen exposure.
  • Practice analyzing oxygen content in your scuba tank.
  • Set your dive computer for diving with enriched air Nitrox.


The enriched air course includes the online eLearning course. Dedicated instructor in-store to teach the use of an O2 analyzer. PADI certification card upon completion.
