How to Use a Strait Line Stud Finder

Updated February 21, 2017

Strait Line is a brand of stud finder that is common in many hardware stores today. Stud finders are used to locate studs behind the drywall. It is sometimes necessary to find the studs for hanging pictures from the wall. When something is going to be hung with a lot of weight, it is necessary to find a stud to support the weight. Typically studs are located every 16 or 24 inches on centre across any wall. Using a Strait Line stud finder is no different than using any other type of stud finder and is the first step toward installing something onto the wall.

Flip the Strait Line stud finder over and open the back battery door at the base of the tool. Insert one 9-volt battery onto the battery connector. Close the battery door.

Move the switch on the back of the unit from off to on. Set the stud finder flat on the drywall and hold in a steady position for about five seconds. Listen for the beeping to stop and the upper red LED light to turn off.

Slide the stud finder in either direction to begin scanning for studs. Move slowly in a straight line along the wall until a stud is located. Listen for a beep and look for the red LED indicator to turn on when a stud is found.

Press the pin marker button on the top of the stud finder to mark the spot of the stud. Continue down the wall, moving the stud finder in a slow straight line. Mark all the other spots where studs are located.


When holding the stud finder in place for five seconds before beginning, it is important that it is not over a stud so it can correctly calibrate. If the stud finder is beeping continuously during calibration, it may be over a stud. Move it five inches in either direction, turn off the unit and begin the calibration again. The stud finder must always be in contact with the surface. The unit may turn off if it loses contact with the surface.
