MSilvia:Personally, I think the PADI Master Diver cert is a total waste. Take the specialties for their own sake. If you've taken them, gotten rescue, and have a bunch of dives, why pay more for a card that doesn't teach you anything you don't already know? It's for card collectors, and not worth the plastic it's printed on IMHO.
I'd rather spend my money on a 6th specialty than on a meaningless wallet thickener, and I'd advise anyone else to do the same. Do you want to be a better diver, or pay to be called one?
WOW! I am going to copy this and in the future when someone ask on SB Ill just paste this responce. As I could not have said it better myself.
