What type of materials will the STHT77406 Stud Sensor scan through?

Surface Differences

The Stud Sensor 200 will scan through common building materials, Including:

• Gypsum drywall

• Plywood sheathing

• Hardwood floors

• Linoleum over wood

• Wallpaper

The scanner cannot scan through:

• Carpeting

• Foil faced materials

• Ceramic tile

• Cement or concrete

• Metal & plaster walls

Wallpaper

There will be no difference in the function of the Stud Sensor 200 on surfaces covered with wallpaper or fabric unless the coverings used contain metallic foil or fibers.

Ceilings

When dealing with a rough surface such as a sprayed ceiling, utilize a piece of cardboard when scanning the surface. Run through the calibration technique described earlier with the piece of cardboard too, to assure best performance of the unit. Also, it is particularly important in this application to remember to keep your free hand away from the unit.

Note: The thickness, density and moisture content of the surface material will affect the sensing depth.
