Pinpoint

Pinpoint is to find the center or the exact location of a detected target.
RACER 2
is a motion detector, 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 still over the target, too.
Ground balance should be performed properly in order to ensure precision of pinpointing.
It is recommended to perform ground balance again before performing pinpoint
operation on changing ground structures.
In the pinpoint mode, estimated target distance information 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 distance 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 position.
