Treasure Seeker Metal Detecting Sandals
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.
