Metal Detecting Sandals
Sure you might look a bit like a huge dork strolling down the beach in these Metal Detecting Sandals, but you'll also be having the last laugh as they detect buried metal treasures. These high-tech sandals use beat frequency oscillation technology coming from a built-in copper coil in the right sandal that is powered via a battery pack that straps to your calf. All you need to do is take a leisurely walk on the sand and if it detects any metal artifacts like coins or jewelry up to 2' below the surface, you'll be alerted with a flashing red light and gentle vibration or an audible buzz. Most likely you'll find an empty beer can or something, but you never know...
