Why do I need a Nitrox certification?

[DiveNav]

........... a skill we practiced was taking off your rig at depth, leaving it at the bottom and ascending to surface. .......

In general I do not like to ascend too fast ..... Specially if I am at 100ft ....

When I dive, the gas in my tank is the most important thing .... For me.
That is why I take along an extra Pony

The proper answer you don't need a c-card to dive nitrox, but due to the litigious nature of people these days, a responsible dive shop owner wouldn't sell you nitrox unless you can prove you have been trained. Also, the op should know dive computers don't figure CNS exposure, and he hasn't shown he understands it either.

As the experienced but uneducated diver that I am, the inaccurate and egotistical responses in this thread (such as the one above) amaze me. Self absorbed authoritarians pecking away at keyboards. I had truly hoped for more upon the original post of this thread.
My thanks to the few that posted simple informative effective answers to this post.

Your post lacked so much common sense I thought it was just someone trolling. You can do all sorts of stuff in life that becomes very dangerous when you ignore standards of behavior and training that exist due to past accidents. What do you want a pat on the head that it'll be ok and another tidbit of internet "knowledge"?
Go seek training from someone or just continue to do foolish things without asking for approval, don't expect atta boys for ignoring current standards.

I don't see anything inaccurate (or for that matter egotistical) in his response.

1. The vast majority of dive centers won't sell nitrox, or rent nitrox tanks, to divers who are not qualified to use nitrox. Liability is one factor. Ethics is another. In addition, any dive center that represents a certification agency will have such conduct stipulated as a standard/condition of membership..

The "authoritarians" who you seem to loathe, represent the dive shops that you might seek to obtain nitrox from. As they own their business, they are free to impose whatever policy they wish in respect of sales and service. Such policies are pretty universal really. Whilst free to do what you want within your own little sphere of the world, you are not free to dictate, or judge, how others should act in theirs.... lest you become the "authoritarian" you detest.

2. The issue of CNS exposure is relevant to any discussion on nitrox - and is something that qualified nitrox divers would know about. The existence, or absence, of CNS tracking on a dive computer is irrelevant unless the user understands the information they are given by the computer and what it represents.

By stating "Flamers need not reply" in your original post, you seem to believe that you can prohibit any other board member from expressing an opinion which disagrees with your original hypothesis. That's a pretty weak opener, IMHO. Luckily, the board provides freedom for members to express their opinions freely on any thread they choose, providing that they adhere to the site TOS. You posed a question in your first post - and it is being answered. This is a learning zone... use it.

I don't even know how to respond to this other than asking you to read up on modern dive computers or take a second look at his post??!!
The funny thing is I am supposed to be the idiot here.

Let me put it in another way. If you were given two survivable choices, where there is a high likelihood of encountering additional challenges on your way out, would you rather:

a. give up your capability for creative problem solving but retain your gas

or

b. give up your gas but retain your capability for creative problem solving

Of course this a hypothetical scenario and in the real world choices "a" and "b" are likely not mutually exclusive--but you could encounter situations where a contaminated fill might mess up your mind. I wonder what a free diver at 200' might think...

Perhaps you need to spell it out for me.

I'd support your supposition though.

I just finished PADI's Nitrox 40%. There were no suprises or I didn't know that moments, except for the EAD table. We were informed there will bo NO dives for this cert. I could have bought a book and tables and have been good to go. Glad I got a $30.00 discount anyway.

I just hate when these discussions turn into cross exchanges,

But regardless of your position on this matter, this post is really funny!!!!!

Cheers,
