Calibrate on the Wall
Place the finder flat on an empty section of wall, press the button and wait for it to calibrate. See best stud finders.
Scan and Mark
Slide slowly across the wall, mark where it signals the edge, then scan from the other side and mark the other edge.
Confirm
Studs are typically about 16 inches apart on center; confirm with a second scan or a small nail.
Avoid Wires and Pipes
Use a model with live wire detection and be careful near outlets and plumbing.
