When visiting the Cayman Islands to check on your bank account, you’ve been known to mix a little business with pleasure and slip in a scuba dive or two. And since your flights out there are usually impromptu (no one ever plans to transfer that much money at once), you don’t always come prepared with your Sony Cyber-Shot TX200V Waterproof Camera. Pick up a TAT7 IPhone Scuba Case ($85.00) while you’re there and turn your iPhone into an underwater camera. Made from clear polycarbonate, the Scuba Case features double gaskets on a hinged open bottom that allows you to submerge your iPhone up to 100 feet. Three buttons on the back let you access photo and video controls. But if you want to post that pic of your fund manager surrounded by a pack of agitated stingrays, you’ll have to wait ‘til you’re dockside. This underwater device is only for point and click.
