PINPOINT
Pinpoint is to find the center or the exact location of a detected target.
IMPACT
is a motion detector (except for the static modes). In other words, you are required
to move the search coil over the target or the target over the search coil in order for the
device to detect the target. The pinpoint mode is a non-motion mode. The device continues
to give a signal when the search coil is kept stationary over the target.
Ground balance should be performed properly in order to ensure precise pinpointing. It is
recommended to perform ground balance again before performing pinpoint operation on
changing ground structures.
In the pinpoint mode, estimated target depth is shown on the display. In the pinpoint mode,
the signal tone increases in pitch and volume as the search coil approaches the target. In
this mode, the device does not discriminate or give target IDs. If the device is in the vibration
mode, the speed of vibration will increase as you get closer to the center of target.
To perform pinpoint:
1)
After a target is detected, move the search coil aside where there is no target response
and pull the trigger back.
2)
Keep the trigger pulled and bring the search coil closer to the target slowly and parallel
to the ground.
3)
Signal sound becomes stronger and changes in pitch while getting closer to the target
center and also the number indicating target depth on the display decreases.
4)
Mark the position which provides the loudest sound using a tool or your foot.
5)
Repeat the above procedure by changing your direction 90°. Actions to be performed
from a couple of different directions will narrow the target area and provide you with the
most exact details of the target location.
