what the different between using Nitrox and Normal Air to dive???

[ianr33]

As for trimix on scuba you are not going deep enough or staying long enough to run into the problem with helium or the benefit of the nitrogen in the mix. So I do not understand why you would even bother with it?

You don't buy much Trimix do you?

He2 ?

Got confuzzeled with all the O2's and N2's floating about.

Narced from too much N2 I guess

I'm baffled that in the age of internet and instant information that there is as much ignorance as there is in this thread.

If what the navy says doesn't line up with the science, then something is wrong. The simplified view of oxygen that you hold is the weak link. I bet you still haven't read any of those studies.

And no, I've done a fair bit of research, talked to many people, and done some diving myself to reach the conclusions of how I dive. And if something more compelling was presented, I'd change. I've done that plenty of times, and I'll do it again.

The Navy is doing the research and using the science that applies. They also read all the other research that is out there. Go to the Panama City facility and you will see they are doing a lot more then just "a fair bit of research". They are also talking to more qualified people then just sport divers!

I have used trimix in saturation diving but not for scuba. While I think it is a much better and safer idea then using nitrox I just do not see much benefit to using it on scuba. I also do not see any down side either to using it on scuba as I do with nitrox.

 

[FWADIVER]

You could still tox on hypoxic trimix despite you claiming you think its safer than nitrox, which goes to show even further you have no idea what you are talking about.

I didn't say you don't USE it,I said you don't BUY it.

If you did you would find Trimix has some significant di$advantage$.

Please, please, please tell me you know that it's ppO2 which is the problem not fO2, you are seriously starting to worry me now!

Read the studies that Rainer posted. Learn some more about scuba trimix and nitrox. I know its tough, but I'm sure you can find the time to do that. The motivation, otoh...
