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.
Realistically for recreational diversRecreational 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.
