Recreational Nitrox Gas Blending Course

EnviroDive wrote the book on gas blending...The PADI/DSAT book!

As more divers understand the benefits of using Nitrox, the need for a ready supply of the gas mix increases. This is good news for diving facilities that can supply this demand. Divers who enroll in a Nitrox course are investing in themselves.

As Nitrox is a relatively new field, there are a lot of myths and misinformation. "Isn’t mixing Nitrox dangerous?", "What about the expense?", "Will I ever recover the cost of setting up a Nitrox mixing station?", "Don’t I need special equipment that has to be cleaned in a laboratory?". We are going to explore these questions and more. Armed with the facts, you can make informed decisions on what is the best gas blending system for your dive shop and how to safely mix Nitrox. We think that you will be pleasantly surprised.

This Enriched Air Nitrox (EANx) Gas Blending Program was specifically developed for people at the dive shop level. As such, we have three objectives:

  • To direct you in the safe methods of blending Enriched Air Nitrox (EANx)
  • To inform you as to what types of gas blending systems are currently available.
  • To provide you with the correct information, so that you can choose what system would provide the best return on investment for your situation.

This comprehensive, one day course of instruction will utilize classroom training, hands on experience, and a comprehensive manual for future reference.
