You make some good points pilot fish and I understand your viewpoint better now.
Since I am a PADI instructor, I can only really speak for the PADI AOW course. With that said, all of my AOW course references are for the PADI program.
I agree that the "Advanced" in the AOW certification is misleading and I think the name of the card should be changed. The PADI program is actually called "Adventures in Diving" but the card issued is "Advanced Open Water". Even PADI does not consider this an "Advanced" certification in the terms so many people think about it. In the context of this course, it simply means expanding your dive education. It is designed to be fun and informative, not challenging.
I do not think it is pointless to take this course immediately following an open water certification because as Len and Duane said, it does provide a review of what you should have learned in OW training and provides additional knowledge and training in a structured/supervised environment. It is not designed to make one an "advanced" diver. The AOW course for example, is nothing more than an introduction to five different specialty areas. The point is to introduce divers to these specialties and show them the different opportnities they have to expand their diving education in the future in areas that interest them.
When I certify AOW students who are new and not very experienced, I make it very clear to them that having this card does not necessarily make them an "advanced" diver. Only time underwater and experience can do that.
Again, the number of logged dives an individual may have is also a very arbitrary number in some ways. For example, someone could have 50 logged dives, but they haven't been in the water for 10 years. Or, someone could have 100 dives that they have logged over the last 10 years.
Another person could have 50 dives that they have logged over the past month. This person is more likely to be more comfortable and "advanced" in the water than the once a year vacation diver. This is not a bad thing, it is a simple fact. Some people are simply more involved in diving than others. Some go through regulator withdrawals after a few weeks, some are happy to dive a few days a year on vacation.
To give a little perspective. I do not dive everyday, but I log anywhere from 200-400+ dives per year. Divemasters here log in the neighborhood of 600 - 800+ dives per year.
Others only have the opportunity to dive on weekends, but they are still diving regularly, keeping their skills fresh and maintaining their equipment. These people can log 100-200 dives per year.
Then there are those fortunate enough to go away on several dive vacations a year. They may get 4 to 5 weeks of vacation diving in, logging on average 10 - 20 dives per trip, so they can easily get 100 dives per year in.
Then there are the once a year vacation divers. They may have been certified for 15 years, but after 15 years, they still only have about 150 logged dives. This category likes to take other types of vacations, have limited vacation time, limited vacation budgets, or simply don't have the same passion for the sport as many of us do. They dive one week a year for 4 or 5 days logging 8 to 10 dives per year. These types of divers are generally not very experienced.
Anyway...I went off on another long-winded tangent...but this is a good discussion!
Thanks for sharing opinions and viewpoints everybody!
