Hello All,
I do agree with many in this forum in that I have been diving Nitrox since the early 90's although I do not feel any different after the dive. (Just me) I know that N2 is not hammering my body. I think most feel the facts are in that Nitrox is, when properly trained in it's use, a far better way to dive. Long-term exposure to shallow repetitive diving on air has been proven to have some serious side effects (Ask any long term fish collector) I know a personal friend who has suffered from the effects of it. I have dove Nitrox for quite some time and have had no ill effects. And you can dive Nitrox deep just not the std 34 or 36 mix which has its limits, but for the most part many diver do not exceed the 130 FSW mark any way. Give it a try "You'll Like it" I do recommend the NAUI course and book. It is very well written and easy to understand. (I am a book worm)
