Review on 5-in-1 Electronic Stud Finder Wall Scanner by M MARSIAN - Auto Calibration, LCD Display, Sound Warning - Beam Finder for Center Finding Wood & Metal Studs, AC Wire Detection by Amir Tune

This tool is very useful for jobs around the house or anywhere where wires and other important cables run. Finding a cord can be a nasty surprise when you're hanging something up or renovating your home. This scanner is very lightweight, portable and easy to use. Just hang it on the wall and read the display, it tells you exactly where the cables are. The instructions were clear and the package arrived within the estimated time. Overall I would recommend this item.
