In this tutorial, we learn how to use a stud finder to locate your wall studs. First, you will use your stud finder tool and place it against a wall. It will go off when it has found the edge of a stud. Place the finder against the wall then slowly move it until the red light on the top beeps. Move it around to make sure you know exactly where the stud would be located. The finder will go off wherever the edges of the studs are to help you pinpoint exactly where the stud is. You could get wrong readings, or just use a nail to poke through to see if the stud is inside.
