4. OPERATING CAUTIONS

Depending on the proximity of electrical wiring 

or pipes to the wall surface, the StudSensor

 

EDGE may detect them in the same manner 

as studs. Caution should always be used when 

nailing, sawing, or drilling into walls, floors, 

and ceilings that may contain these items.
To avoid surprises, remember that studs or 

joists are normally spaced 16 in. (406 mm)  

or  24 in. (610 mm) apart and are 1

1

2

 in.  

(35 mm) to in width. Anything closer together 

or a different width may not be a stud, joist, 

or firebreak. 

Always turn off the power when working 

near electrical wires.

5. SCANNING DIFFERENT SURFACES

Freshly painted walls: 

May take one week or 

longer to dry after application. 

Wallpaper:

 The StudSensor

 EDGE functions  

normally on walls covered with wallpaper or 

fabric, unless the materials are metallic foil, 

contain metallic fibers, or are still wet after 

application.

Lath & plaster:

 Due to irregularities in plaster 

thickness, this tool is not recommended for use 

on lath & plaster.
The StudSensor

 EDGE cannot scan for 

wood studs and joists through ceramic tile or 

carpeting and pad.

Note: Sensing depth and accuracy can vary 

due to moisture, content of materials, wall 

texture, and paint.
