Digital multi-detectors Pyle

LED/Audio, 9V, 250g The PMD24 uses electronic signals to locate the exact position of studs, AC wires and metal through drywall, concrete and other common materials. Once the edge of a stud has been detected, the PMD24 emits audio and visual signals (LED Display) that allow you to narrow in on the center of the stud. The PMD24 locates metal objects and live conductors as well. Felt cushioning allows the PMD24 to easily slide across walls without damage. The visual and audible indicators alert you to the presence of conductive metal or live voltage. Ideal for use in the field or at home. Adjustable sensitivity for detecting studs or metal/voltage. Powered by 9V battery (not included)
