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.

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.
That’s what everyone is supposed to do.I analyze my tanks because I don't know (trust) what is in them until I verify it myself.
Do you know why? What shortcomings do you feel you had in your remote session?My wife and I talked an instructor into doing that a few years back. They wouldn't again.
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.Do you know why? What shortcomings do you feel you had in your remote session?

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