Underwater Metal Detectors

The underwater metal detector assists the search and recovery diver by enabling him to detect metal objects beneath any substrate under water. Usually, objects being sought have been silted over, or, in time, have settled into the soft bottom where they become obscured from view. Without the aid of a metal detector, the diver must physically probe the bottom using his hands to feel for objects. Depending on the sze of an object, the metal detector can scan and detect deeply below the surface. Quite often, underwater evidence searches involve guns which can be easily detected by a metal detector. The recovery of evidence that may have been thrown in the water is critical to many investigations, and often leads to the apprehension of the perpetrator involved. An assignment to recover evidence is just one of the many tasks performed by an underwater search and recovery police diver.
