I can relate to having lots of self-taught time in addition to what's required for the classes. I read everything I can get my hands on related to diving and still feel that I'm just scraping the iceberg.
As to Doc Intrepid's comments, they're well-taken. I guess I'm trying to understand the PADI approach before becoming too critical (I'm up for IDC/IE next month, and I'm trying to align a little more with their mindset in preparation. It's an interesting exercise, since I do things very differently in practice - much more safety-oriented, BP/W with long hose, no snorkel, etc...)
What's really in question is just what the minimum standards should be for each cert level. I mean, do warm water reef divers need to be DIR-F and have certs in Cavern and Trimix? I like the populist approach, all the while acknowledging that it left me pretty hungry for more theory and practical application, which I've done on my own at each certification level. I think the committment to continuing education is part of the process of professionalization, and I'm not really sure that replacing some of the more arbitrary components of basic scuba training would be helpful in that regard.
Interesting thread. Lots of issues and as many opinions as there are members reading it.
