It's my opinion that more people should be diving. It's an awesome sport and we should be showing that to everyone. Hell, that's what ScubaBoard is all about.
It's my opinion that people should do whatever they want, and unless they're someone
I want under the water with me, I couldn't care less whether they're diving. Except to the extent that fewer divers means fewer people, on average, crowding up boats and sites
Do you feel that we don't need additional divers? If so, why?
Here you're making a jump that doesn't necessarily follow from your opinion as stated above. If more people should be diving because
they're missing out, that's a problem for them...is it a problem for divers who aren't treating the sport as a paycheck, though? Who is it that
needs more divers, exactly?
And what's implied by the word
need? Without them, we'll see no additional innovation? Our present manufacturers will go out of business and we'll be left diving with what we've got? A bunch of LDSs and some marginal and/or has-been brands will shrink, go belly-up, or be bought by more successful competitors?
But since you asked me why not (personally, I think the person advocating for people to give their money for a cause bears the burden of explaining why), here's what I see. Tech diving has been
exploding in terms of innovation and options as well as in terms of how many divers are doing ever-deeper/longer dives and spending tens (Hell, some of us are spending hundreds) of thousands of dollars to do it. Just look at the latest CCR tech from companies like JJ, ISC, and rEvo; look at the SW Petrel and NERD; look at the DPV tech from SS and Logic Dive Gear; look at the stuff Halcyon and LM are cranking out. We may be looking at a revolution in O2 cell development in the next couple years--and it's not coming from the kind of businesses you're saying do serious R&D work that benefits the sport, it some tiny-ass company in Europe who may or may not give us an actual, workable solid state O2 cell.
Nor are people I see (and again, I'm not a pro, so maybe the people who need to weigh in here are the tech instructors like Doppler) fueling that just guys and girls who've been doing vanilla rec SCUBA for years and years and are now gradually moving into tech. Instead, it's seeming to be the goal of a lot of divers who are either just starting out or are damn close to it. They tend to be motivated, self-directed, and see serious diving as a demanding sport worth their time and attention -- and money. And why not? Unlike recreational diving, it's giving you the tools to go somewhere you might be a genuine explorer, even if it's just some new piece of cave/a tiny or nearly flattened old wreck/or just some ledge at 500' nobody's seen before. Unlike stuff like Everest, there's nobody you can pay to haul you to the top--if you have what it takes, you'll come back, and if you don't you well may not.
These divers spend, per capita, what has to be tens if not hundreds of times more on diving than the average diver. However, they tend not to be interested in the kind of overpriced hand-holding that comes along with the LDS dealer model that's necessary for your average vacation diver.
All in all, I'm not convinced
diving is in need of saving; certainly tech diving isn't. I'm ready to believe the kind of
diver that has traditionally supported a lot of SCUBA companies and small businesses may be an endangered species...but I don't see that as a problem so much as a benefit of there being a lot more useful information and smaller companies available to potential participants.
