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