EnviroDive Services presents the newly revised and updated

“Blending Oxygen Enriched Air”

 In the days when nitrox was just catching on, the diving industry found itself in a dilemma. Instructing eager divers how to dive nitrox was easy enough, the bottleneck was in the mixed gas supply. Basically, there were very few shops where newly certified nitrox divers could get their scuba cylinders filled.

 Often with all of the misinformation surrounding nitrox blending, divers found that before they could get a nitrox fill they had to have their nitrox dedicated cylinder (and valve) oxygen serviced….usually at a considerable expense. Unfortunately, many nitrox divers found that getting nitrox was not worth the problems encountered at the dive shops.

 Near hysteria and paranoia surrounded the almost cult like mysteries involved in nitrox gas blending. Clearly, it was past time for a well-researched and comprehensive manual on gas blending. This need resulted in the EnviroDive manual on “Blending Oxygen Enriched Air.” This time tested manual was the foundation for subsequent manuals on gas blending published by “Best Publishing” and PADI/DSAT.

Blending Oxygen Enriched Air - Cover art

 As the world leaders in nitrox gas blending, EnviroDive Services is excited to offer our customers an instantly downloadable copy of the original - but revised and up to date - “Blending Oxygen Enriched Air” manual for the low price of $7.99

 A lot of the original issues surrounding nitrox were based on closely guarded secrets designed to protect the few businesses with the knowledge of nitrox gas blending. Nitrox gas blending became an industry driven by myths……Until EnviroDive Services published the “Blending Oxygen Enriched Air” manual.

 Easy to read and understand. Get the facts. Find out for yourself what is myth and what is real. Be safe. Get your copy this minute. What are you waiting for?
