PINPOINT
MENU
Targets buried very deep can take on values close to the surrounding ground, to the point that they are
most often rejected as the ground itself. The Gold Field and Relic programs allow you to go deeper when
searching for native gold in mineralized ground or for large masses at depth, as they only reject the local
ground to which you have adjusted precisely by Grabbing. Ground compensation is therefore a priority
in both these programs. Occasional ground variations and large mineralized stones with a different value
from the surrounding soil may make the device react. Set them aside for future reference.

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.

Choose a threshold reset in Automatic
mode or Manual mode:
A.T ON
: 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
(default mode) : The audio detection threshold is re-calibrated manually
by pressing key briefly (Manual Re-Tune).
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 field 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.
