Pilot Fish, you havent been here long, and all i can say is that this has been beaten to death already, AOW doesnt mean Advanced in any sense of the word, just a new range of experiences so you can broaden your horizons a bit. The addage of dive within your level of training or within the type of environment you were trained in does limit you somewhat as to the kinds of places you can dive. My OW training was in a lake, max depth was 36ft, but i went and did shore, boat, cavern, night, deeper than 60ft, zero viz types of dives over the course of my first 30 or so dives. The idea behind the minimum dive count for some AOW type courses is so that you have a chance to work on what you learned in OW training in a similar environment to that in which you learned - get used to breathing underwater, work on buoyancy control and the like before task loading yourself up other stress (depth, lack of light, navigating - properly, searching, recovering etc) inducing factors, which should be where the AOW course comes in. Some people have lots of cards in a very short time, dont do much diving outside instruction, others get out there and dive before getting more cards, some of each of those look great UW, others still look a complete state after 100+ dives, its all relative. Like i said, this subject comes up pretty once per month, in this or the new2scuba section along with "which agency should i do it with?" which makes little difference as its the instructor who determines how well they teach the subject and how well you have to do at whatever skills to sign you off on the card.
