Nitrox Requirement

[jasondbaker]

I'm not Grumpy but I feel grumpy after being trapped at the MSP airport for 12 hours and counting.

I think the #1 problem with putting new divers on nitrox is that they don't understand the depth limitations.  I was on a boat last week where a relatively new diver had no clue she needed a depth gauge or computer.  The dive master went chasing after her when she decided to explore the deep blue. 

I was also diving with a buddy that had just completed his nitrox class two weeks ago.  He couldn't figure out why his computer was beeping at him when he decided to go to 125ft on nitrox-32.
