A stud finder finds the hidden studs in your wall, allowing you to securely attach objects with minimal damage. Adjusting a Strait-Line stud finder to the wall before looking for studs enables the tool to perform optimally. The procedure is straightforward and does not require any previous experience with a stud finder, regardless of the manufacturer.


Step 1

Tap on the wall with your knuckles until you hear a hollow sound, which indicates the unlikelihood of a stud.

Step 2

Press the stud finder firmly against this area of the wall while sliding the power switch to the "On" position, and then to the "Off" position, and then back to the "On" position. Continue pressing the stud finder against the wall as you hear a series of beeps and see the LED on the stud finder illuminate.


Step 3

Continue pressing the stud finder to the wall until the beeps stop and the LED goes out. Your Strait-Line stud finder is now adjusted to the wall.


To find studs, slide the stud finder laterally until you hear a beep and the LED illuminates. Push the pin-marker knob to mark the presence of a stud. Continue moving the stud finder until you have found as many studs as necessary. Remove the stud finder from the wall and turn the power switch to the “Off” position.


Moving the Strait-Line stud finder too quickly on the wall can lead to a false reading.
