CONTROL SETTINGS
Sensitivity (Depth)
Press the MENU touch pad to display
SENSITIVITY on the screen (shown with
factory setting at approximately 75% as
indicated on the Upper Scale), and you can
use the + and - touch pads to adjust the
sensitivity at which your detector will oper-
ate most effectively. These changes will be
shown on the Upper Scale. Although the
instrument’s maximum sensitivity (depth)
is usually desired, this is often not feasible
because of the type of soil over which you
are scanning or because of electromag-
netic or power line interference. Ground
mineralization and other considerations
can limit the detector's ability to interpret
target information. This control option
permits you to achieve a stability that per-
mits maximum detection depth possible
in relation to any specific environmental
conditions.
