@Angelo Farina you bring up some interesting points. I wasn't around (as a diver, at least) in the halcyon days of yore, so I can't comment on the training back then. I have heard stories of it, though, and a few things come to mind. First, the hardcore training of old definitely seemed to have some items/skills in it of dubious value. Second, the physical fitness and mental toughness required for some of the old training acted as a filter of sorts on who decided to pursue dive training in the first place. I'm guessing that students - and thus, ultimately, certified divers - were disproportionately young, fit men. Third, and very much related, is that most students and divers were people who were serious about diving.
Was that the best model? Perhaps in some ways. Perhaps not in others. We need to find a balance between making dive training accessible while also keeping it as safe as possible. To be clear, I'm certainly not arguing that we weaken standards and dumb down the teaching so that anyone can become a diver. In fact, I'm for strengthening standards. But somewhere along that spectrum is the proper balance point. I can't tell you where, exactly, it is though.
The way I see it, one of the major problems is with dive marketing and its downstream impacts on students and dive pros. Because in many ways the marketing is either driving the standards or is at least related to them. Despite what the training agencies - and, let's face it, it's predominantly a PADI thing - want people to believe, no, not everyone can or should become a diver. We don't necessarily need to filter out all but the most hardcore people. But we also need to be realistic about the fact that while rec diving is relatively safe, it comes with the potential for some extreme consequences. It irks me to no end when I see people sign up for OWD certification courses who have no business doing so. I'm talking about people with severe fear of the water, with major anxiety issues, people who cannot swim, etc. We've all seen and dealt with those students. Some of them work hard and actually earn their certification. Some of them drop out. A lot of them, however, manage to squeak by and get certified because the standards bar is set so low and because instructors are trained in such a way as to churn out certified divers.
I won't pretend I have the answers, and there are lots of folks on these boards who have been at it far, far longer than I have who have a ton more insight. But for starters, at the very least, I think training agencies need to get a much better handle on the quality control of their instructors. Snow, for example, should never, ever have been allowed to become an instructor. I'm surprised she even made it through her DM training.
We also need a Flexner Report of sorts when it comes to dive schools, and a lot of IDC mills need to tighten up their game or be shut down.
The prerequisites to become a dive pro need to be strengthened. Divers should have a LOT more experience before they are allowed to make the transition to pro. No more zero-to-hero crap.
Students should not be taught on their knees, ever. We need to stop overweighting students just to get them to the bottom/platform so they can do the skills, get out, and move on to the next dive. We need to stop allowing students to bicycle kick and hand scull their way through the water. All these things make for sloppy diving and lead students to believe that sloppy diving is fine. It's not. If we want to have a culture of serious divers, we need to cultivate that from the very start.
Not everyone is cut out for diving.
Almost everyone can learn to dive. But we need to let students know - and demonstrate it through every step, action, and approach we take - that it will take work and dedication on their part.
