Target Edge Mapping
The Target Edge Mapping procedure uses an
'edge detection' technique to locate the outer
edges of a target thereby mapping the size and
shape of the target. Pinpoint and Detection
Modes can also be use used during the
mapping process.
NOTE: Pinpoint Mode is slightly less
sensitive than Detection Mode and may
not work well for extremely weak target
detections. In these instances, use
Detection Mode to map the target. Where
a target is small Target Edge Mapping
may not be required and so proceed to
Target Pinpointing.
Target Edge Mapping Procedure
1. Move the Coil away from the suspected
area of the target and enable Pinpoint Mode
by pressing and holding the Mode Button.
2. Move the Coil to approach the target area
from a variety of angles.
3. When there is a target response, mentally
mark the position on the ground.
4. Continue this process until a clear mental
picture of the target size and shape
is obtained.
Warning: Extreme care must be
taken when mapping the target
to ensure the Coil does not touch
the ground or exposed parts
of the threat.
Target Pinpointing
Having mapped the area of a suspected target,
the Target Pinpointing procedure can be used
to determine the centre of a target.
1. Hold the Coil away from the mapped target
and enable Pinpoint Mode by pressing and
holding the Mode Button.
2. Sweep the coil over the target. The
detector alarm response will increase to
the maximum before reducing when the null
zone on the Coil is directly above the target.
Small Coil movements left and right of the
null causing an alarm response will confirm
the position of the target.
3. When the null point is reached mentally
mark the centreline.
4. Repeat the process with the detector
oriented at 90° to the first sweep. The
intersection of the two lines will indicate the
target location.
5. If necessary, enter Interrogation Mode to
obtain or confirm information about the
target composition.
