Md Edge Mapping Procedure; Mapping Multiple Targets - Minelab MDS-10 Operation Manual

MD Edge Mapping Procedure

The MD edge mapping procedure uses Pinpoint
Mode to identify the outer edges of a metal target
when only the MD Sensor is enabled.
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
(steps 2 to 5).
Do not select Pinpoint Mode when
the Sensor Head is above the target.
This may result in the target being masked.
1. Move the Sensor Head away from the target
and enable Pinpoint Mode by pressing and
holding the Trigger button.
The Pinpoint icon will appear on the LCD, and
the audio responses will change.

Mapping Multiple Targets

The Operator may find multiple objects of
interest in close proximity but may want
to locate them separately.
Use the normal target location
procedures to determine the locations of
multiple targets. An irregular shape may
emerge, allowing the centres of individual
targets to be pinpointed within it.
2. Move the Sensor Head to approach the target
area from a variety of angles.
Do not use the short sides of the Sensor Head
(see Sensor Head Null Zone on page 48).
As the Sensor Head approaches the target, the
Target indicators will indicate that the target is
in close proximity.
3. When there is an audio response, mentally
mark the position on the ground.
4. Move the coil away, and approach the target
from another angle.
5. This process continues until a clear mental
picture of the target size and shape is
achieved. The Operator will also be confident
that the target is contained in the mapped
area.
Once the target has been mapped, Pinpoint the
centre of the target (page 50).
