If you are a geek then your first choice for a vacation spot may not be the beach, it's probably to places like the Space Center in Houston, Fan Expo in Canada or the Tokyo Game Show.  But if your vacation plans are to a sunny beach locale then I'm sure your vacation checklist contains items like your smart phone, laptop, and plenty of sunblock.  One more item you need to include on that list are these Metal Detecting Sandals from Hammacher Schlemmer, while you are taking a walk on the beach you can locate hidden treasure.
