Metal Detector

During crime scene searches, it is sometimes necessary to locate small metal objects (i.e. bullets, cartridge cases, etc.) that are not visible due to long grass, snow, being underground, etc. These objects can frequently be located by using a metal detector.  The image below shows the metal detector in use to locate cartridge cases in grass.
