The Draper 501G Combined Metal Voltage and Stud Detector is a multi-function diagnostic tool designed to locate hidden objects and electrical cables in walls without causing surface damage. This compact detector helps electricians, plumbers, and contractors avoid costly mistakes when drilling or fixing into partition walls by identifying the precise location of concealed hazards. With a maximum depth penetration of 27mm, this detector identifies live or dead electricity cables, metallic water pipes, nails, and other metal objects behind plasterboard and partition surfaces. The integrated stud detection capability allows carpenters and installers to locate timber framework quickly and accurately, ensuring secure fixings for heavy items like wall-mounted cabinets, radiators, and shelving units. Measuring just 120 x 75mm, the detector is compact enough to carry in a toolbox or pocket yet delivers reliable detection across multiple materials. Each unit includes a detailed instruction leaflet to help users get the most from its combined metal, voltage, and stud-finding functions. The detector requires a PP3 9V battery, sold separately.
