Review on Enhanced 5 in 1 Stud Finder Wall Scanner - Ultimate Wood Beam, Drywall, Joist, Pipe, AC Wire and Metal Studs Locator with LCD Display - Best Electronic Wall Detector for Precise Edge and Center Finding by Rich Schobinger

Who the hell gave this bullshit 4.5 stars? We found about 15 studs - then when we started drilling it was just drywall! There was a new bolt every half inch. Calibrated about 15 times. When we found hairpins and then drove this piece of garbage back through the territory, suddenly there was no hairpin! As!?!? You'll have better luck just blind drilling through the wall, which we did. I almost knocked that goblin to the ground and hit him with a hammer. but I wanted that return. Also read the instructions. which were clearly written in another language and then translated into English. Maybe hieroglyphs. Don't buy this, it's junk and you'll probably kill yourself by piercing electrical wires, which this fool calls bolts. garbage
