STUD SCAN AND DEEP SCAN
Use Stud Scan Mode to find the center or metal studs up to 1.5 in. (38 mm) deep.DeepScan Mode is a higher sensitivity scanning mode that should be used when there are extra layers of wallboard or paneling. To minimize false positives and/or finding other objects further behind the wall that may not be a stud.
In order to get the accurate results, please always start in Stud Scan Mode when looking for studs.

METAL SCAN

Use this Metal Scan Mode to locate and avoid hazards, such as pipes, behind walls and determine if a stud is wood or metal.
