detection by factory-set discrimination.
You can then use the ACCEPT/REJECT
touchpad to eliminate these pesky pieces
of junk, no matter which Discriminate
mode you are using. Just move your
searchcoil across one of them, watch your
Upper Scale for its response and push
the ACCEPT/REJECT touchpad. The Lower
Scale notch vanishes, and you'll have
no more trouble from that type of trash
metal. With the GTI 2500 you spend less
time digging trash and more time digging
coins!
Custom discrimination enables you to
design your own coin-hunting mode. Any
Custom discrimination selections you make
will be retained in the detector's memory
even after the instrument has been turned
OFF.
Find even more coins by combining the
deepseeking capabilities of the GTI 2500's
All-Metal mode with the discrimination of
the Discriminate/Coins mode. When you
detect a deep target in the All Metal mode,
examine the target ID on the display
panel and/or switch to the Coins mode
