Metal Detecting Sandals.If you think it’s a little bit nerdy wandering around a beach waving a metal detector from side to side a solution is now at hand, well feet actually; the Metal Detecting Sandals (white socks optional).
These are the sandals that can detect metal while you walk, allowing you to find buried artifacts while strolling the beach. A copper coil built into the right sandal is powered via a battery pack that straps to your calf. Using beat frequency oscillation technology, the ring creates a magnetic field; when a metal object is underfoot–up to 2′–it distorts the field and the battery pack alerts you to the presence of metal using a flashing red light and either a gentle vibration or a clearly audible buzz.
