BuoyantC:I also agree with others that it is the instructor (and the dive shop) that makes the difference. As to the comment that PADI is too simplistic, I would answer that if you are only going to remember a percentage of what you were taught, keep it simple enough to remember the important stuff. For example, only a Dr. need be concerned about the difference between pneumothorax vs. mediastinal emphysema. It might be facinating reading to the truly interested, but necessary to be a good diver? Naw.

That has been a long debated question. I first ran into it when becoming a pilot. When I was learning to fly, it was mandatory that pilots do spin training. Put the plane in a spin and recover. Spins scared some people, so they started only requiring stall training as you cannot get a plane into a spin unless you stall it first. Is one method better?? Maybe... who knows.
It is interesting - for fun I've asked a lot of Padi divers how deep you have to be to have a "lung overexpansion injury" and the standard response I get is 33 feet. I've even gotten this from instructors. Scary.
By giving information on the seriousness of a lung expansion injury, I do not feel I am over taxing my students. I don't think their scuba brains are "fully saturated" and the additional info will cause other info to off gas...
but maybe that's just my view.
Of course we also do things like work on buoyancy instead of promote a "peak performance buoyancy specialty". We do basic rescue scenarios instead of a "tired diver tow."
The philosophy of Padi and Naui are definitely different, and I think potential students should be informed of the differences and make their own decision.
