Iâve tried a few budget stud finders in the $20â40 range, and most were unreliableâone didnât work at all. This one, however, is flawless. It comes with 2 AA batteries, so itâs ready to go right out of the box. It immediately located studs with an audible tone, and also detects wires and metal. I especially love the built-in marking hole in the centerâit makes it easy to pencil your spot without guessing. Excellent tool and well worth the price.
