5-in-1 Electronic Wall Detector Stud & Wire Finder

5-in-1 Wall Detector for Accurate Stud, Metal & Wire Location

Need to drill, mount, or renovate with confidence? This 5-in-1 Electronic Wall Detector is designed to help you quickly locate studs, metal objects, and live AC wiring hidden behind walls, floors, and ceilings, reducing the risk of damaging pipes, cables, or structural elements. Its handheld design and clear LED display make it suitable for both professional tradespeople and home DIY users who need reliable, repeatable results.

Engineered as a multifunctional electronic measuring instrument, this detector uses upgraded internal sensors to read changes in material density behind opaque surfaces. It can identify wooden studs, joists, metal pipes, rebar, and live electrical lines, helping you find the stud center with improved accuracy. An integrated alarm alerts you as you approach the target, so you can fine-tune positioning before drilling or fixing. The LED green backlight screen provides clear visual feedback, even in dimly lit work areas.

The housing is made from durable PC/ABS in a practical silver finish, keeping the unit lightweight and easy to handle over extended use. A simple front interface and manual operation mean there is no complex setup: select the mode, place the detector on the surface, and slide it smoothly to locate hidden objects. Powered by a standard 9V dry battery (not included), it is ready to go on job sites, at home, or in workshops without the need for charging docks or cables.
