I agree w/ dhoward... I have been a commercial diver for over 15 yrs and a scuba diver for approx. 20 yrs, however I don't get to scuba dive much anymore. What dhoward said is correct, it is not as easy as getting some Nitrox and going deep. There is a completely separate set of dive tables that you need to follow, and you should know how to figure PP/O2 and know what it means for depth limitations.

I personally never agreed w/the scuba communiuty having acess to mixed gasses, it gets (inexperienced) people into situations w/a limited amount of gas and bottom time and decompression becomes a whole new problem to deal w/. This is just my opinion, I know that thousands of dives are made each year successfully w/no incidents or accidents, but I also know that there are more and more decompression related incidents every year because new and young divers get their certification and feel that it's their ticket to do whatever they want.
