Tip - A threshold hum
is recommended as
it often fades over
rejected targets providing
information about targets
and ground conditions.
If the constant noise
bothers or distracts you
and reduced AUDIO
THRESHOLD doesn't
help, select SILENT

5. Silent Search
The ability of the detector to be operated without
the threshold or background hum that is normally
heard continuously during operation. The
instrument is silent until a target is detected.
Select SILENT SEARCH with the ARROW
controls and use the ENTER control to turn
SILENT SEARCH ON or OFF.
To function, SILENT SEARCH requires AUDIO
DISC ON and MIXED MODE OFF. SILENT
SEARCH "ON" will automatically override both
AUDIO DISC and MIXED MODE menu selection
to perform the silent search function regardless
of your AUDIO DISC and MIXED MODE
selections. See chart on left side of this page.
In Pro Options the Discriminate feature can
be used to accept all metal targets while using
SILENT SEARCH. It is not possible to achieve
a non-motion searching mode with SILENT
SEARCH ON. When SILENT SEARCH is
ON the all metal pinpointing mode continues to
produce a threshold. This may not be noticed,
as once the pinpoint mode detunes for better
target center locating the threshold is not present.
However, releasing, re-squeezing, and holding the
TRIGGER with the loop at waist level a threshold
will be noted. Press ENTER.
