And just to take it one step further (sorry if I dont make my point clear, i'm just about leave for work so rushing this post) one only has to have 100 dives, show "experience" in deep diving (could be one 40 metre dive maybe?) and have done rescue and DM to become a PADI instructor...so is the diver that rushes through to Instructor in the shortest time imaginable a better diver than the guy with 400 dives on an OW cert? Maybe in the point that he has done a rescue course but in actual diving ability?If you see an OW diver card, and an AOW diver card, each from a diver you haven't met before, do you honestly expect one to be a better diver than the other?
I know a guy who is a PADI MSDT, TDI Advanced Tri-mix and GUE Tec 2 and Cave 2. I wouldn't dive with him because he is egotistical megalomaniac and I believe this makes him dangerous in the water.
The point is that people get hung up on cards when really attitude and experience should examined when taking into account any divers diving ability.
