CONTROL PANEL
"Gain" increases, or multiplies, the strength of signals from buried metal objects.
G IN versus THRESHOLD
For maximum detection of the smallest or most deeply buried objects, increase
the Gain. To minimize the weakest signals, reduce the Gain.
"Threshold" controls the detector's audio level. Positive threshold values
increases the audio response of weak target signals. Negative threshold
values suppress sensitivity.
For searching at maximum sensitivity, first set the Gain at a low level. Then
set threshold into the positive region, with a comfortable background-hum
volume level. Then increase Gain to a comfortable level, free of chatter.
Increase Gain to a slight amount of chatter if you can tolerate the chatter
while searching.
For silent searching, set threshold to a negative number, and also reduce
Gain if necessary. Silent searching will result in the loss of some sensitivity.

3. PINPOINT

Pinpoint temporarily engages a no-motion detection mode. Searchcoil
motion is not necessary to detect metal. Any metal within the searchcoil's
detection field will induce a sound. Pinpoint is generally used to determine
the exact location of a target previously detected in Discrimination Mode.
