Yes, I've experienced that. I was with an OP this fall with my new nitrox cert ready to try nitrox on my own. I had been on nitrox previously on AOW course under guidance of the instructor. Different OP and island. They were very thorough. Well there was no onboard analyzer for customers to use, just go by the label they said. They didn't even want to see my Nitrox cert. This is all pretty new to me, how often do you see lax safety standards?No that would not be option 2. The tanks come from an independent fill station already labeled. You're welcome.

I'd rather not say.Where was this?
I once did a scuba refresher with a woman who had developed an interesting alternative to the two choices listed in this survey. She was a highly experienced diver, and it had not been all that long since her last dives. In the water, her diving skills were excellent, and I saw her dive, I skipped the normal refresher content to work on more advanced diving.
But it was in setting up her gear that things got interesting. She had all her own gear, including an air integrated computer. I gave her the shop supplied tank, she put her gear on it, and she turned on the air. She looked at the computer and commented that it had successfully identified the gas in the tank as 32% nitrox.
I did a double take. What? She repeated that her computer had analyzed the gas and determined it was 32%. I assured her that her computer did not analyze the gas, and that the tank had nothing but air in it. No, she said, I was wrong. The tank had nitrox in it, because that was how she always analyzed her gas, and it was always right.
I told her that the dive shop through which I was teaching that class did not supply nitrox for swimming pool dives, it did not have any of the equipment in the shop to make nitrox, it did not have any regular employees who could make nitrox, I was the only one in the shop who could do it, and I did not put nitrox in that tank. I assured her that at some point in the past she had successfully analyzed a tank of nitrox at 32%, had correctly set the computer for that level, and had forgotten that between trips. She was apparently always ordering nitrox 32 for all her dives on subsequent trips, so the fact that the computer was set to 32% reinforced her false memory that it was reading the mix for her. Luckily, the mixes she had gotten must have all been reasonably close to 32%.
It took a while, but she eventually believed me.
It also shows something else.That's a tragic case of someone not understanding the information their computer was giving them. I've run into that before as well ... particularly with people who do not comprehend what happens to their dive computer once they cross the NDL line. It's almost frightening that these people can dive for so long without hurting themselves ...
