Stanley Stud Finder Instructions

Updated February 21, 2017

When installing shelves or hanging art, mirrors or other heavy items, it is best to hammer nails or screw attachments into a solid stud rather than a hollow wall section. Electronic stud sensors such as the Stanley Stud Finder give off electric signals to detect studs in the wall, and alert the user when a stud has been found. The Stanley Stud Finder is appropriate for finding wood or metal studs in bare, painted or wallpapered walls.

Open the battery compartment in your stud finder and add a fresh battery if necessary. Stud finders generally don't come with batteries included.

Hold the stud finder firmly vertically against a hollow area of wall.

Hold down the "ON" button once to select ½-inch stud depth detection, twice to select 1-inch depth detection and three times to select 1 ½-inch depth detection.

Wait for the stud finder to calibrate, and continue holding it still and steady against a hollow area of wall. The LCD screen will display the word "CALIBRATING." When the finder is ready to use, it will beep, and the screen will display the word "READY."

Slide the stud finder in a straight line along the wall. As the unit approaches a stud, bars will display on the screen. When it detects the edge of a stud, it will beep. Mark the wall to indicate this edge.

Keep sliding the unit across the stud. It will turn off and stop beeping when it reaches the other edge. Mark the wall to indicate the other edge of the stud. The centre of the stud is between the two markings.
