I added "regulators" to guage your reaction Genesis. I'm very pleased to see you did not take the bait.I once bubbled...
. . . Some drivers might wish to service their own cars (or regulators) but are prevented from attending the necessary courses for the same reasons you describe. In addition each manufacturer has his own special tools. . .
Indeed teaching scuba is not Rocket Science and people can be taught to dive withount fullly understanding the infinite details of the sciences involved, just as they can be taugh to drive safely, even if they do not understand the very basics of the workings of the internal combustion engine or change a wheel. Couples have divorced as a result of the (unqualified) husband trying to teach his wife to drive. My mother did not pass her test until I was well into my thirties. I still hate being driven by her (which, thankfully, is not often)!
I always had my regulators serviced professionally, even though I consider I may be more than capable of doing it myself:- One of the first things the police asked following my accident was when and who performed the last service on it. The implication being, if the equipment was at fault and I had serviced it (or not), I would have had only myself to blame.
. . and if I had I died my life insurance companies would have had a field day.
