I can appreciate everyone's opinion. My point is, If the industry does not try to maintain some kind of "self policing", the government (State or Federal) will. I don't think that is what anybody wants. Maybe it is? My opinion is I don't want the government (state or federal) involved in yet another facet of my life. I am already legislated and taxed on enough. A shop or an operator can simply state it is their policy not to sell air fills or not to allow someone to dive from their boat if they do not have a certification card, and that is good enough for me. If they get around it and dive from a private boat using their own compressor, it is their responsibility to be trained, not mine. I want no part of their negligence.
