PLASTER AND LATH
Due to the uneven thickness of plaster, it may be difficult to locate
studs. It may be easier to identify the metal nail heads in the studs. If
the plaster is reinforced with wire mesh, the hand-held radar scanner
will not be able to reliably detect objects behind it.
TEXTURED OR ACOUSTICAL WALLS AND CEILINGS
When scanning a wall or ceiling with an uneven surface, place thin
cardboard on the surface and scan over the cardboard.
WOOD FLOORING, WOOD SUB-FLOORING AND DRYWALL
OVER PLYWOOD
Due to the thickness of these materials, it may be difficult to detect a
wood stud or joist. It may be easier to detect the metal nails that hold
the materials to the stud or joist.
CARPETING
The hand-held radar scanner cannot detect studs or joists through
carpeting. It may be easier to detect the metal nails that hold the
materials to the stud or joist.
NOTE: Sensing depth and accuracy can vary due to moisture,
content of the materials, wall texture and paint.
