DISCRIMINATE MODE
Mode Selections
When you touch the POWER touchpad,
your GTI 2500 is ready to hunt in a
Discriminate/Coins operating mode with
threshold, sensitivity (depth), tone and
other controls preset at the factory, as
shown in the GTI Screen's upper center as
you step through the Menu. As explained
in the following pages, settings can be
easily changed through regulation of the
(+) and (-) touchpads.
In its Discriminate mode the GTI 2500
functions like most other detectors and
must be moving slightly for detection to
occur. Microprocessor-controlled DSP cir-
cuitry of the GTI 2500, unlike that of ordi-
nary detectors, however, adapts automati-
cally to the speed of any movement. This
means that your searches will have the
same high degree of accuracy whether you
are scanning rapidly to cover a large area
quickly or moving slowly over a location
with multiple targets. Automatic circuitry
is designed to provide precise ground bal-
ance at any speed.
