Actually diving doubles is an old thing... But...
It's not you... It's your shop.
If this is as you describe, then they should be ashamed of themselves.
The reality of diving is... Most divers are "look at the pretty fishy" divers, where the gear may cost around $2000 all in (but you could probably get outfitted for less than $1500)? Tech Gear (3 or more sets of regulators, doubles, stages, bailout, lights, reels, etc) you're looking at the neighborhood of $5000 if not more. So It sounds to me like this is a way to find a profit center in "today's economy"?
Tech diving is a very small portion of the diving community as a whole. However, you'll find that on internet forums... this may not be the case.
But take a step back and look... Tec divers so into it... they have to talk about it when they're not diving?? Go figure.
If I'm getting this right, I
think this is a shop that specifically supports some of their divers to move towards GUE Fundamentals.
If that's the case, then I think the OP is overstating the amount of gear being sold to newer divers.
At the Fundies/Essentials level, you don't need three sets of regs or stages or bailouts. For the rec pass the requirements would be BP/W, regs, paddle fins, bottom timer of some sort, an SMB/reel, and backup lights. That's probably going to cost
less than someone geared up in a ProQD, Legends, Slingshots, D9, and C8 eLED light. Even if the BP/W has blue
H's on the harness.
Maybe for the tech pass you'd need doubles (so another wing) and an expensive light. I sincerely doubt anyone who is new is being pushed for a tech pass out of the gate, they are probably being sent away to practice buoyancy and propulsion and ascents and s-drills and shooting a bag first.
Because the OP is being vague about the shop he's complaining about, we can't nail down how much of this is real vs. how much is vague enough so nobody can be sure how much gear we are really talking about.
