students who price shop on training are not planning on becoming divers, because certification is usually the very cheapest part by far about being a diver. (It should not be, but it is. Unfortunately the only people charging significantly more for OW tend to teach overly long self-aggrandizing courses, so the more expensive courses tend to get a bad name because the instructor is just ego teaching.)
If the students are trying to, or have to, spend as little as possible to get a license, they are certainly not going to spend any more to actually go diving, since they already achieved the goal.
I think all this may be true for some, but is completely wrong for others, so as general statements, these are worthless.
I price shopped for my OW cert - hard. I paid $300, but that included everything except for me providing my own snorkeling gear, which I was free to use what I already had or buy from anywhere I wanted. That is the cheapest I have ever seen a COMPLETE (except for snorkeling gear) OW cert package for, and I shopped on and off for 2 years before I was finally able to get 'er done.
It's been 5 months since I completed my OW cert and I now have all my own gear, including (so far) 1 tank and 1 pony. And I have completed 2 additional certs, so far, and am in the middle of a combined course right now that would give me 5 more full certs, if I want to pay the registration fees for them all (I'm only going to actually claim 2 of them). And I think I will take the class to get the TDI Nitrox cert (already have SDI Nitrox) this weekend. And have logged 20 dives, so far (counting the 4 OW cert dives).
The reason your statements are wrong for me (and, I would guess, at least some other people) is that I REALLY WANT to dive. And I'm on a limited budget. So, I price shopped hard in order to be able to afford the class. A very nice and unexpected Christmas bonus allowed me to go on a spree for a bunch of gear (all used or Closeout specials). Without the bonus, I would still have bought a few of the things and still be working on scrounging the rest.
I also think it's pretty lame to attribute bad motives or instruction to a shop strictly based on the price of the class they offer. You know, some businesses DO operate on the principle that starting a customer off as cheap as possible will bring them into the fold and good customer service will keep them there.
Just because the stats for a $99 class shows higher attrition than a $500 class doesn't mean that the $99 class is turning out any less real divers. It might just mean that the $99 class is turning out as many (or more) real divers and ALSO turning out a shload of people who at least now have some exposure to scuba diving, even though they never do it again.
If a shop could train two people at $500 each and they become "real" divers, what is wrong with training those same two people plus 8 more at the same time, all for $100 each, as long as they provide the same quality of training? Maybe one or two of those 8 extra people will turn out to be a "real" diver, too, and isn't that better for us all, in the long run?
I think, instead of complaining about shops offering cheap classes, if anyone is concerned about classes that are turning out incompetent divers that are nevertheless certified to go diving all on their own (with a similarly skilled buddy), maybe it would be better to focus on what the standards are that are producing this situation. Maybe there should be an intermediate level of certification that allows you to dive, but only with a certified DM as a guide?
And maybe DM certification should be stratified into DMs that are certified to lead dives of only divers with full certifications and a higher level for DM that allows leading dives that include people with that intermediate OW cert. Or maybe just additional standards for DMs, with no stratification. If a DM goes out with people with full certs, they don't have to even get in the water. But, if they are leading a dive that includes anyone with the intermediate "guided dive only" cert, the standards require that they get in and lead any of those people that will follow them.
Regardless, if the certification is that "you are now certified to be capable of diving all on your own (with a similarly skilled buddy)" and the current standards are resulting in MANY divers that really, simply, are not actually capable of doing what they are "certified" to do, then it seems that either the cert needs to change, the standards need to change, or both. It's not something to fix by getting rid of $99 classes.
Also, why NOT have some Scuba Police? If an agency wants to gain or maintain a reputation for producing solid, capable divers, why not have a few instructor examiner type people whose job is travel around to dive sites and offer divers some incentive to take a quick test. If the diver is found to completely fail, then it's a demerit on the Instructor license of whoever certified them. Enough demerits and you have to go through Instructor remediation. Enough more and you lose your Instructor license. Obviously, done with some intelligence. You wouldn't want to ding an instructor for a student that trained 5 years ago and has done nothing since, and now it turns out they are a bad diver. That's not (necessarily) the instructor's fault. Anyway, it seems like maybe the WRSTC should be doing this, so they can ding anyone that is part of any agency that is accredited by them.
