Would you find an annual get together of the players in some other sort of fashion to be equally as effective? I go to DEMA because of the parties. Not because I like to party, but because I do far more business on the dance floor than I do the show floor. As I say, BTS is a close second for me, and I do more business at the show than I do at the DEMA show. What would you replace DEMA with?
When we (me and TDI) conducted a survey asking divers what shows they visited and why they went, certainly the social aspect was a high motivator... hardly surprising. To pull an old cliche from under the bookcase here in my office, sales is about chemistry and networking is an effective chemical catalyst.
I'll explain my suggested alternative to exhibiting at trades shows when I see you at BTS. In addition to that strategy, ANY consumer show is going to be more effective for someone selling to consumers! ANY event that offers our customers -- divers, boaters, outdoor enthusiasts, Star Trek freaks, car nuts, whatever -- workshops, seminars, product knowledge AND the ability to BUY is going to be more effective than a straight-up trade event that bars kids (the next generation of divers), non-divers (people thinking about diving), casual divers (qualified leads), and non-professional but avid divers (low-hanging fruit by any definition), is cutting itself off at the knees.
That is just my opinion. I think it's an informed opinion, but I have no current real primary research on which to base it. Perhaps it's time for another survey!?
Anyhow, your situation is a little different in that you sell to clubs, shops, and individual punters. But numbers (money in pocket numbers) don't lie.
