– Objects lying at an angle in the wall
– Metal surfaces and moist areas; if in a wall, these may be displayed as objects under
certain conditions (e.g. high moisture content).
Please note that concrete requires several months to dry out completely.
– Cavities in a wall; these may be displayed as objects
– Proximity to devices that generate strong magnetic or electromagnetic fields, e.g. mo-
bile phone base stations or generators
Before drilling, sawing or routing into walls, refer to other sources of informa-
u
tion to ensure that you eliminate hazards. Since the measuring results can be influ-
enced by ambient conditions or the wall material, there may be a hazard even though
the indicator does not indicate an object within the sensor range.

The maximum measuring depth is 8 cm. Any deviations from this value are described in
the individual wall types and views.

other homogeneous materials. It displays plastic pipes and metal objects as well as elec-
trical and other cables. Cavities in masonry or empty plastic pipes with a diameter of less
than 2 cm may not be displayed.
Wall Type <Concrete>

well as electrical and other cables in drywalls (wood, plasterboard, etc.). Filled plastic
