I came from another industry in decline to join this one. That being the Aviation industry. They too are crying about losing pilots and people not flying as much blah blah blah (of course they also have a heavy-handed Fed agency that doesn't much help their issue).
Neither that one nor this one are for everyone. Money AND leisure time are the key to any hobby. Right now, I think its fair to say that everyone is pretty cautious about where they spend either of those. Bang for the buck.
Good service standards, good product standards and good safety records are by far the most important to attracting and retaining the right people for this sport. That if anything is what should be promoted industry wide IMHO.
After getting to the end of the thread, I was thinking the same thing. I've been involved in recreational aviation since late 80's and if good diving were available in eastern Nebraska at the time, I might have dove more! Since the late 80's the recreational side of aviation has also taken a large dump and most of the participants blame costs. A small Fixed Base Operator in TX recently went 2 weeks with $1 a gallon fuel, and the demand was through the roof, leading to a supposition that it was indeed costs keeping pilots grounded. Then there's a study that indicated if aircraft and fuel costs from 30-40 years ago were adjusted for inflation, well, they're about the same.
At one of out local airports here (Thun Field - Puyallup, WA), a guy took over the local fuel concession and pilot shop and appears to have turned it around. He's got the cheapest fuel around and built out a shop where pilots can get a cup of coffee and hang out. It's neat, inviting, and they have a great staff.
I'm not saying that cost is the overall driving factor in diving, I don't think it's got a whole to do with the industry - people are going to spend money, it just depends on their interests. Personally, I've been spending more time diving this past year instead of flying (and my aviation log show's it!), with limited free time, folks have to make decisions on where to spend time.
I think the LDS situation is probably the biggest issue in capturing new converts to the sport. Make the LDS an inviting environment and staff appropriately. Folks just wandering in to a shop don't want to be intimidated by over inflated egos behind the glass counter. We had a local shop that had no counter - just kitchen table of sorts, where customers felt at home and could just hang out. No cash register for the most part , all transactions were done on iPads and that concept seemed to work, at least from that aspect. The shop didn't survive, but that particular concept seems to work well.
Back to the previous post, presenting a good service in a welcoming environment is going to go far in capturing and keeping new divers. As they say, "all politics are local", and this is most likely true for the LDS.
