Few things have revolutionized recreational diving in the past decade as much as the introduction of Enriched Air Nitrox (EANx).

 Nitrox is nothing more than the air you are breathing right now with some additional oxygen added to reduce the concentration of nitrogen. Breathing less nitrogen provides divers with several benefits. Among them:

  • You enjoy longer no-decompression limits and shorter surface intervals — especially on repetitive dives.
  • You reduce the risk of decompression sickness compared to making the same series of dives using air.
  • Your dive computer (required for the course) should be capable of tracking your exposure to both air and Nitrox. Isn’t it time you started taking advantage of your computer’s capabilities?



Students must meet the following prerequisites:

  • Be certified the Open Water Diver level.
  • Be at least 15 years of age.
  • Be able to answer No to all questions on the PADI/RSTC Medical History form, or secure a physician’s approval for diving prior to the start of the course



What is Involved?

This course involves self study and an informal group discussion, during which you will review the homework and get hands-on practice analyzing cylinders and logging mixtures.



Except as noted, classroom sessions take place either at our Willoughby or Fairview Park locations.


When Can You Start?

Weeknight classes typically run from 6:00 until 9:00. Saturday class sessions typically run from 8:00 until noon. Important: Confirm these times with the store before the start of class.
