Review on 🔎 Kuled M79 3-in-1 Multi-Function Stud Sensor Detector with LCD Display and Sound Warning - Wall Scanner for AC Live Wire, Wood, Metal - Deep Scanning by Paul Walton

Works great and the instructions are quite simple. I've been watching videos too, but if you're like me and have never used any of these: 1) Hold the nail finder up to the wall before turning it on. 2) Press and hold the side button until it beeps and hold it down while searching for nails 3) Locate the posts by slowly moving the viewfinder along the wall in a horizontal direction. If he beeps, you've found him!
