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?




What is Involved?

This course involves self study and a bried classroom session, during which you will review the material 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.
