Review on Advanced 5-in-1 Stud Finder Wall Scanner with Intelligent Microprocessor Chip and HD LCD Display - Locate Studs, AC Wires, Metal Studs, Joists, and Pipes with Precision by James Cabot

A very handy tool for the homeowner, especially for those who love DIY. When trying to identify the hairpin in my video, an electrical wire was found that we were unaware of. This is accurate and shows the center of the hairpin and its tip with arrows. You have to press and hold the button on the side, wait for the screen strips to scroll up and down, then place it on the wall and see how it detects the stud or electrics.
