The WG 18 Handheld Metal Detector is very effective for locating even tiny metal objects that may have been concealed, or even ingested within body cavities, with pinpoint accuracy.  It incorporates Linear Detection Technology, which allows all metals to be detected at any angle. The WG 18 has a fully adjustable detector to allow for "maximum find capability." It also features a two-position rocker switch or "Turbo Control," to the left of the on/off switch. In the forward position this switch enables the operator to fully adjust the detectors sensitivity by turning the "Turbo" or sensitivity adjustment knob. The operator can then conduct a super high sensitivity search sweep of the subject. However, when the operator wishes to continue the search to the lower leg and foot area, the operator simply switches the "Turbo Control" to the back position. This now allows the WG 18 Handheld metal detector to eliminate large amounts of static metal in flooring (i.e. re-bar or steel beams), walls and ceiling, while still being able to detect, for example, a hand cuff key or a small piece of razor blade in the shoe or sock area, accurately and reliably.
