Md Pinpointing Procedure - Minelab MDS-10 Operation Manual

MD Pinpointing Procedure

After the target edges have been mapped, the
MD Pinpointing procedure is carried out to
precisely determine the centre of the target.
If the target contains metal, and the metal in the
target is sufficiently small, the area mapped will
also be small, therefore it is easier to identify the
centre of the target.
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 find the centre
of 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 mapped
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.

2. Sweep the coil over the target.
If the target contains metal, the MD audio
response will increase to the maximum
pitch when the sensor heard is immediately
adjacent to the target centre.
3. When a response is heard, mentally mark the
centreline.
4. Repeat the process with the detector oriented
at 90° to the first position. The intersection of
the two lines will indicate the target location.
5. To disable Pinpoint Mode and return to
Detection Mode, release the Trigger button.
Once the MD target has been Pinpointed, it can
be Interrogated (page 51).
