Using the Wall Scanner
4. Radar View
This scene is suitable to scan for
compound objects (multiple types of
objects) such as voids and iron bars
in a block or brick.
With no display of burial detection
marks, scan results are shown in
waveforms only.
(See "Searching for iron bars in a
block fence" in page 48.)(*)
(*) Some buried objects may not be detected up to the maximum detection
depth depending on their size, shape and material, as well as the material,
condition and internal structure of the wall to be scanned.
