Fortunately, I am in an industry that gets very busy during emergencies and I will be spending as much as I can afford at local businesses especially dive shops. Unfortunately I may have to wait until they reopen after the current crisis.
 
I cant help but feel kind of bad when thinking of shopping for stuff I don’t absolutely need. Some people out of jobs right now won’t even have the funds to buy groceries. I guess I’m lucky in some way.
 
The same way you would test a known tank????

I analyze my tanks because I don't know (trust) what is in them until I verify it myself.

the point is, you, as the tester, already know the answer....

That’s what everyone is supposed to do.
 
So if I have my own analyser or borrow one and analyze/label on screen, would that be good enough?
My wife and I talked an instructor into doing that a few years back. They wouldn't again.

Do you know why? What shortcomings do you feel you had in your remote session?

There were none. Of course I had the nitrox tanks and the analyzer. He refused to do it later for a guy who dives with us. Nitrox course is a little bit of nonsense really. You can learn all you need to know to safely dive nitrox in about 10 minutes.

Recreational nitrox can be summarized as follows:
1) Choosing a max ppO2 (typically 1.4 for OC active, 1.6 for deco - but that's for later)
2) Calculating the MOD based on (1) and adhering to it
3) Programming a DC for the gas oxygen content and the max ppO2.
4) Calibrating an O2 gauge and then measuring a cylinder
5) Labeling measured cylinder
6) Recording parameters (o2%, MOD, cylinder information, etc.) in log at gas provider
7) monitor accumulative o2 exposure (for rec divers, this requires A LOT of diving)

While I don't think that 10 minutes is enough, I do think that some background is important (EAD for example; oxtox is a function of time, ppO2, and genetics; etc.). But in reality, the items above is pretty much what people are going to take away from a course. We hopefully can agree that there are risk factors in not adhering to industry practices.
 
Something to think about in terms of helping a LDS. We had one suddenly close. Any air fill cards were worthless. If you had equipment at the shop and could prove it was yours you got it back. If you had paid for stuff and not got it yet you lost the money. You were able to get some cert cards because it was PADI and the instructors could work as independents at their own expense.

Not saying don't do something to help but it should be disposable money.

1.4 is still too high for the active portion of OC diving, but otherwise I agree
