I think for already established divers, we'll probably be traveling less. Less exotic destination, more local dives - Florida, Bahamas, Cancun, etc... Where you still can get good deals - and less than 4 hours away. I think local dive charters in the Great Lakes might actually see more business.
I wonder if on the retail side, you are going to be selling alot less high end brands, and perhaps training alot less new OW students. I can see how the discovery scuba/scuba diver rating might still be wanted.
The economy has not hurt my business, yet. But the number of bad accounts has doubled, if not tripled since two years ago. I am sending so many more folks to collection. And two who has not paid are actually lawyers working in prominent law firms and still earning good money. Go figure.
