Wow, what a thread! After reading through it I feel compelled to chime in as a newbie to the board.
I first dove solo without any (as in zero) training at 16 y/o in Lake Michigan in 1977. Dropped off from a Whaler and later picked up. Over the side I went, over weighted and without any BCD. No SPG, no depth gauge, just a tank of air and a wetsuit, mask and fins. I loved it but struggled to regain the surface even though a MVP sprinter. Probably should've died then, looking back. Did OW and AOW via the University of Iowa for PE credit in 1980. These courses were a quarter long and intensive. We dove in quarry water with enough vis to barely see our wrist compasses for nav. It was fun. But after getting AOW I did ten or so dives at various sites in the Midwest and then dropped out for the past 25 years.
Flash forward to the present. I just got back into the sport when our 8 y/o daughter received a Make a Wish trip (very mixed blessing) to the Atlantis Resort in Bahamas for a dolphin swim and I realized I had to dive while there. While I like my LDS and the instructors (PADI), the courses (retaking due to my prolonged absence) are not nearly as intensive as the originals.
But I will make this observation from my peculiar personal history: New divers typically have a (short term) reason for getting certified. Originally, mine was a simple desire to learn and explore (thanks Jacques Cousteau!). This time, it was getting on a charter boat with renewed skills. I believe (as has been said) most OW divers are doing it for the tourist diving alone. That said, I can't personally fault PADI or any other organization for making it as simple as possible to accomplish safely. I believe it's up to the instructors to create an experience that (1) educates the students to safety and efficiency in diving, and (2) provides the students with a new perspective on the sport - one which promotes an interest in taking it further intellectually, similar to what a professor might do with a university student.
It's up to you educators, not PADI or NAUI or YMCA or any other formal organization. It's up the the individuals who instruct us. And then it's up to us. That's what is compelling about the Harvard vs. OSU analogy raised earlier. My (personal) example would be law school. The courses are essentially the same across the accredited board to obtain a Juris Doctor degree. It's the instructors methods that make the difference in the end, not the price of the degree or the hall you sat in and whether it was covered in ivy. And then, it's what the student/graduate does with it.
I get what I can from my local instructors. I get a lot from this board, too. And then it's trial and (hopefully not much) error. I'm in the middle of my second AOW course - 25 years later! I'm enjoying it. It's a bit over-priced for 5 dives with a few specialty programs, but I consider the extra a donation to the much appreciated LDS (thanks Pam!).
But what I am interested in is what you experts would recommend in terms of course work and training to someone with less than 50 dives. The AOW course (or program, whichever), is pretty clearly not a big step. I'm assuming the Nitrox course is much the same. It does kind of piss me off that it's $250 to obtain cert to use it. Now that seems like a scam. Correct me if I'm wrong.
And thanks for all the useful info!
