Nitrox

[MMM]

None of the threads below have mentioned that as part of nitrox training, you will be taught the importance of analyzing the tank given to you and the procedures in doing so. So if you can get an op to give you nitrox without a nitrox cert, up to them I guess. But nitrox certs aren't all that expensive (less than $200 when I did mine) and all in all worth the effort since you'll get a couple of dives thrown into that as part of the cost.

If and when I take a nitrox course, I will base what I do afterwards on what I learn there and by talking it over with my instructor.

Um, perhaps you misunderstand me. I certainly will not be trying to get nitrox on Cozumel (or anywhere else) without first taking the course.

Sorry again!

If one doesn't want to get a nitrox computer but still wants to use nitrox after getting certified then the best way to go is to turn your air computer into a bottom timer and ONLY use your new nitrox tables to make sure you don't get lazy with your calculations. This way you always know for yourself and don't rely on your air computer in any way other than as a timer and depth gauge.

I do agree that Nitrox really isn't as safe as some LDS's claim it to be however over the course of a week of diving those small percentages do add up and theoretically make a dif.

Good point. I forgot to mention that as well.

I own my own analyzer. I use it to test all nitrox tanks that I use. I bring it onto the boat with me as well. If you are travelling, it is really nice to bring along your own analyzer. If you have taken good care of it, that will give you an assurance that it is working properly. And you won't need to wait on the boat, while others use the boat's analyzer, assuming that it is working.

You will learn to analyze your tank contents when you pick them up, on land, or before you hook up your reg to the tank, on a boat. You will also be asked to sign a log, stating the oxygen percentage of the tank that you analyzed, and stating what your max depth is for that percentage, both of which you will need to fill in and then sign.

Thank you for an educated response to this question about O2 toxicity.

Why would anyone not dive with enriched air if they had the opportunity. I believe the benefits outweigh the problems associated with enriched air. Cozumel is loaded with Nitrox. $10.00 a tank. A small price for insurance.

Are you sure about that? O2 CNS half-life is 90min and so you would be clear after 9hrs even if you were at 100% of your O2 clock. If you are talking about whole body toxicity you would have to remain at 1.6 PO2 for 7.3 hrs to exceed a daily dose. Do you really do that much diving that it's a concern?

MMM, It is absolutely rediculous to discuss someone diving a mix of gas that they are not trained/educated to do so. Sorry, a bit extreme but not out of the realm, this stuff can kill you if you dont know what your doing! Diving nitrox without being certified is incredibly dumb. Especially in a place like Coz where there are many instances where there are no hard bottoms. If your not trained how do you know what your risks are?

Ok, now I am off my soap box.

Actually, MMM was reacting to a post of mine which he erroneously interpreted as me saying I might be diving nitrox without bothering to get cert'ed for it. I won't be doing that, nor was I ever considering it.

Absolutely true. I agree.
However, most of what you need to know to dive EANX you can learn during the boat ride out to the site.
