Been diving for many years now, and finally decided to go into the advanced specialties. Master Diver and beyond. Problem is, my local SSI dive shop doesn’t have much demand for the advanced courses, so I’m at a loss when I have random questions. I was able to get into nitrox class, but it will be hit or miss if people sign up for anything after. Question is nitrox related. What is the practicality of using ean32 as a travel gas down to about 100ft, switching to air for the dive, then going back to nitrox for the ascent?
