Some shops will even tell you that you can't hook up their analyzer to your O2 bottle because you'll burn out their sensor. Bottom line, everyone that dives a lot of Nitrox should have their own analyzer.
Yes! Not just Nitrox, whatever gas you're diving, air, 02, mix...make sure it's what you think it is. I received a "free" unexpected 10/50 top-off when I was expecting 32%....from a place using banked gas. Ooops, wrong whip, eh? It was a while ago, but the lesson stuck.

My most common mistake? Forgetting to bring my overnight bag on dive trips....gear, I got....clothes....ummm...Wal-Mart trip! Well, that, and sometimes I can't find my sunglasses...because I'm wearing them. At least I make my dive buddies feel really smart in comparison
