Enriched Air


The Enriched Air (Nitrox) Diver Specialty Course will qualify you to dive with mixed gas that contains more oxygen (up to 40%) and as a consequence, less nitrogen.  This will allow you increased bottom time dives as you are absorbing less nitrogen and you don't reach your non decompression limit (NDL) any where near as quick as when diving on normal air.  This certification will qualify you to dive on enriched air (nitrox) anywhere in the world.


Course Outline

You will have 2 training dives during this course, where you will conduct all of the planning and gas mixture analysis, and then experience the benefits of the increased non decompression limits.

The Enriched Air (nitrox) Diver course covers:

  • Managing oxygen exposure

  • Analyzing oxygen content in your scuba tank

  • Setting your dive computer for diving with enriched air nitrox

  • Dive planning with different gas mixes
