5.3.2 Conducting a Magnetometer Scan
Right after activating the “Magnetometer” mode, no sound should come from the device. If you
can hear any sound output, repeat the ground balance. Make sure you hold the device straight
downwards to the ground, as you would do during the scanning process, and run the ground
balance by pushing the
button. After that, the sound output should be silent.
Move slowly forwards, backwards and sidewards, but avoid turning the probe. The probe should
always point vertical to the ground.
DO NOT
pivot, swing or turn around its own axis.
As soon as an acoustic signal sounds, the device has detected a potential metal target right un-
der the position of the probe. In this way it is possible to find small metal objects near the surface
like nails, screws, wires, seals and similar targets.
You should use the operating mode "Magnetometer" to remove such disturbing metal pieces
from the area that you like to scan. The less metals near to the surface, the better your result in
the operating mode "3D Ground Scan". You can also find larger metal targets which are located
deeper underground.
A general rule is: The larger the target, the deeper it can be detected underground.
Also you can use the operating mode "Magnetometer" as a useful pinpointer during the excava-
tions. If you already have dug out a large hole and do not remember where exactly the detected
object was situated, you can simply use the Magnetometer mode to relocate fast and efficient
the target position.
After using this operating mode for a while you should process a new ground balance by push-
ing the
button. To finish the operating mode "Magnetometer" and return back into the main
menu you simply press the
button.
