I would expect a Master Diver to know what their SAC is. I'm talking about any agency, not just PADI. I was certified by PADI many years ago by the way when there were real courses. It's my opinion that all agencies have much less stringent courses now than they have in the past. This is tempered by the instructor who can turn out superb divers with any agency if they are contentious.
