SENSITIVITY + AND –
These controls change the detector's sensitivity;
higher settings enable detection of deeper
targets. At power-up, the detector is pre-set to
75% of maximum sensitivity. At minimum, the
sensitivity is 35% of maximum. With each press of
the + or – touch pads, the sensitivity level is
displayed on the bar graph on the left of the
display. Upon reaching the minimum or maximum
sensitivity setting, the detector will beep twice.
While higher levels of sensitivity enable detection of deeper targets,
operation at high levels of sensitivity make the detector m

to suppress interference or false signals from soil minerals when necessary.

This mode is a ground-balanced All Metal
motion search mode. This mode offers the
maximum amount of sensitivity under most
ground conditions. The search coil must be in
motion to detect metal. One monotone sound
is
emitted.

The Sensitivity control works like a course adjustment in this mode.
The Threshold control works like a fine adjustment in this mode.
The AUTO TUNE mode must be ground-balanced to eliminate interfering
signals from soil minerals. See the section on ground balancing for a
description of this procedure.
