The same dive shop that fills my nitrox fills my oxygen.I wonder how you manage this? If you have a solid grasp of what you're talking about, you do know, of course, that there is no oxygen tank where we divers pick up Nitrox.

So we came to the same thing I said before: you trust the guy who filled your tank. End of story.The same dive shop that fills my nitrox fills my oxygen.
There is at least one training agency (obviously not PADI, SDI, or SSI) whose standards dictate that any dive below 100' must use Helium. Their thinking is that the risk of getting narked is too great past 100' without Helium in your mix. Obviously, there are divers who think the same way, or there wouldn't be an agency with those standards.
No, I don't. I analyze everything I breath. Air-100% oxygen.So we came to the same thing I said before: you trust the guy who filled your tank. End of story.
Thanks, plus/minus 0.2% O2 looks nice. But we do not know their SOP how they test it. Like I said, most likely this is done in the air when results do not depend on the flow (as they disclose on pp 13 and 15).Try looking at the manufacturers specs. For instance, page 23:
MO2-865 O2 EII Pro Technical Manual.pdf
And maybe you still believe in Santa? Oxygen analyzers used by divers in dive shops to check tanks are so inaccurate you can use them only to tell if you got air or some kind of Nitrox, and then trust in the guy who mixed it. But if I am already taking extra risk by diving solo, why would I add another risk factor? Risks do accumulate, just like errors.
The only scuba police worthy rule infraction that I saw was the viz sticker placed without an even cursory inspection and that only beacuse he charged for work not done. That is a rules violation in my book.And whose rules were being broken? The Houston scuba police department?
I am interested in understanding different peoples perspective on "scuba rules". Seems like lots of people are inventing lots of rules.
Certification agencies make rules that must be followed by instructors for training dives. Other than that, each dive op is free to make up any (or no) rules they desire. Although some places do have some odd government rules.
Last time I rented a tank the only card I presented was my visa. Even stranger, they asked me what size of tank and I said "a small one, those big ones look too heavy to carry". I definitely did not come across as a diver that knew what they were doing (I was renting the tank to service my regs...).
Who thinks there is such a thing as "standard scuba rules"?
