Hammacher Schlemmer's Metal Detecting Sandals let you locate buried treasure unobtrusively as you stroll the beach.
The sandals have a copper coil built into the right sandal—powered by a 9-volt battery pack that straps to the calf with an elastic band. Using beat frequency oscillation technology that creates a magnetic field, the battery pack alerts you to the presence of metal up to 2 feet underfoot by using flashing red LED lights and either a gentle vibration or a clearly audible buzz.
The sandals have PVC uppers, non-skid soles, and polyurethane foam footbeds. The black sandals come in two unisex sizes.
