Typical Target Detection Signals
Deeply buried, large metal mines and small metal parts near the surface can
be differentiated by an audio alarm signal.
Move the search head with continuous speed above the ground surface.
The maximum detection signal is produced directly above the center of the
mine (metal part) and indicated as follows:
a)
Maximum volume of the audio signal.
b)
LEDs on the display are illuminated (length proportional to the strength
of the audio signal)
c)
Vibration in the hand grip.
