RS PRO RS-LA101 3 in 1 Stud, Metal and AC Voltage Finder

Introducing the RS PRO RS-LA101 Stud Detector, which has been designed to detect metal or wooden objects embedded within building and construction materials. This 3 in 1 stud tester uses electronic signals to locate the edges of studs, joists or live wires through drywall and other building materials, ideal when drilling is required to ensure that these areas remain undamaged and untampered with. This simple but effective detection tool improves efficiency when trying to locate embedded items and reduces guesswork, unnecessary and accidental drilling and even damage to drill bits.

Features and Benefits:

  • This RS PRO cordless 3 in 1 metal, stud and AC voltage detector is an ideal unit for the detection of items embedded in building materials

  • This device uses electronic signals to accurately pinpoints metal or woodwork objects to avoid accidental damage through drilling and reduces unnecessary holes and guesswork to locate embedded objects

  • Once the edge or a metal or wooden beam has been detected, the detector sounds an audible alarm and illuminates on the unit to highlight detection of an object

  • It detects metal or wooden studs from 0-38mm through drywall

  • Live AC wires can be detected from 0-50mm through drywall

  • The detector is handheld and powered by a 9V battery

  • Supplied with a 9V battery and gift box


A stud finder or detector is a device that has been designed to detect embedded or deep-lying objects like ferrous and non-ferrous metals, wooden substructures and live cables within building materials like drywall, bricks and concrete. These types of devices are often used to eliminate guesswork and accurately pinpoint objects when need to drill or bore out holes within the building materials for further construction or building. If a live cable accidentally gets drilled into, it could cause electrocution or pose a risk of fire, which is why it is important to ensure that such embedded objects are accurately pinpointed to ensure no damage is done. A device this like is essential for those working in the following industries:

  • Cable and wiring installation

  • Building and construction

  • Electrical systems installation
