Gpr Detection Threshold; Adjusting Gpr Detection Threshold - Minelab MDS-10 Operation Manual

5. Short‑press the Skyshot button to proceed
to GPR Detection Threshold adjustment
(page 41).
Each short‑press of the Skyshot button will
cycle back through the Start Gate, Stop Gate,
and GPR Detection Threshold settings.
6. Long‑press the Skyshot button to return to the
Detect Screen.
The Start and Stop Gate markers will remain
on the Detect Screen for reference, but will
not be displayed on the Detect Screen if they
are set to 0 or –100.

GPR Detection Threshold

The GPR Detection Threshold setting adjusts the
threshold at which the GPR will give a detection
response (audio, vibration, LED, and red GPR
overlay) for weak targets in the GPR Imagery.
The GPR Detection Threshold setting has a
range from 0 to 100 with a default setting
of 30.
A higher GPR Detection Threshold setting will
result in more detection feedback for weaker
targets, but also more false alarms due to ground
clutter.
A lower GPR Detection Threshold setting will
reduce false detections due to ground clutter,
but will also result in less detection feedback for
weaker targets.
Note that GPR Detection Threshold works similarly
to GPR Sensitivity, however it applies the same
to targets and clutter at all depths, rather than
proportionally increasing with depth, as GPR
Sensitivity does.
Adjusting GPR Detection
Threshold
1. With the GPR Sensor enabled, long‑press the
Skyshot button. Start Gate adjustment will be
displayed.
The Skyshot button
2. Short‑press the Skyshot button twice to
display GPR Detection Threshold adjustment.
Each short‑press of the Skyshot button will
cycle through the Start Gate, Stop Gate, and
GPR Detection Threshold settings.
3. Use the Plus (+) and Minus (–) buttons to
increase or decrease the GPR Detection
Threshold level.
4. Long‑press the Skyshot button to return to the
Detect Screen.
