PINPOINT mode is used to operate the coil motionless above a target. It is useful for locating metal targets
inside houses and cellars and is also widely used to follow underground metal pipes.
Access to PINPOINT screen, then update the detecting threshold with a quick
press (Re-Tune manual).
Pinpoint (Target localisation)
Position the coil barely off the
ground and to the side of the
target. Press
to calibrate
the threshold.
Move the coil slowly across the
target. The loudest sound and
highest audio pitch indicates the
target position.
To narrow the eld of detection and im-
prove the target location: Position the coil
close to the target but not on the center.
Press
to re-tune the threshold then locate
the target as step 1.
AUTO-TUNE ON/OFF: Choose a threshold reset in Automatic mode or Manual
mode:
A.T ON (default mode) : The audio detection threshold is automatically calibrated
to the metal environment or to the soil. With every sweep over the target, the
threshold is lowered in proportion to the level of the target to reduce its detection
zone and thus localise it better in the following pass.
Conversely, if you remain far away from the target for a few seconds, the thresh-
old will rise again gradually until the next pass over the target.
A.T OFF: The audio detection threshold is re-calibrated manually by pressing key
briey (Manual Re-Tune).
