My wife an I were certified for nitrox many years ago, but have seldom dove anything other than air. There were several reasons for this, including the expense of the fills, having to rent or dedicate a tank, seldom doing more than two dives in a day, not owning an analyzer, etc. In the past decade and a half, things have changed a bit, such as banked nitrox and membrane compressors are much more common so you can get fills without dedicated equipment, and less expensive fills. When I have dove nitrox, I was always able to either borrow the shops analyzer or have them test the tanks in my presence.
My question is this, is it practical to dive nitrox without having your own analyzer? I would like to start using nitrox more, and we have a boat trip scheduled for the end of the month which has EAN32 available. I am not sure how practical this would be without having our own analyzer. What does everyone else who do not have an analyzer do, just fall back to using air? At this point, I don't think we would use an analyzer often enough to justify the cost and maintenance.
If you can't analyze the gas , you don't dive it period!
