Review on 🔨 Upgraded 5 In 1 Beam Finder Wall Scanner Detector - Quickly Locates Wood, Metal, Studs, Pipes, Rebar, Joists, Live AC Wires - Enhanced Visibility with Large Clear LCD Display by Robert Blair

When trying to hang a wall mirror in my house, I made the mistake of driving nails into 2 different walls and hitting the beam both times, and now I have to I cover the flat hole and the damaged paint. Wish I had bought this little thing before I did. But now that I have it, I have successfully hung my mirror in a good place. Note to self: Always use this helpful nail finder before hanging anything again! It's good quality, easy to calibrate and use, and the instructional video was very helpful.
