A medal detector comes useful in treasure hunting, searching for land mines, detecting weapons such as knives, and also in detecting foreign metal bodies in food. It makes use of electromagnetic induction to detect metal.
One fun way to make use of a metal detector is to comb the beach for some unexpected finds. Most to be found in the beach are coins and jewelry. There are commercial metal detectors available specifically for this hobby.
