If you like outdoors and exploration like me, you will definitely want to get one of these flip flops that act as a metal detector the next time you head out to the beach.
Not only these metal-detecting sandals look cool, they can disguise what you are doing. Plus, your back won’t hurt from carrying a big-ass metal detector.
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.
