SETTING DISCRIMINATION (Notches)
Using only the discrimination of its factory-
set Coins, Jewelry, Relics and Zero operat-
ing modes, the GTI 1500 will more than
satisfy the requirements of almost every
treasure hunter. Many will never require
any other discrimination. Still, this detec-
tor offers more, Custom discrimination, to
tailor a detection mode to any requirement
by setting precise detection "notches."
The Lower Scale contains Discrimination
Segments. Those that are turned on
(darkened) represent targets whose con-
ductivity will cause a "beep" when they
are detected in any operating mode. In
the Zero mode all segments are turned
ON, which indicates that almost every
metal target will cause the "beep" of a
detected target. Through use of the +, -
and ACCEPT/REJECT touch pads, specific
"notches" can be created by turning dis-
crimination segments ON and OFF in any
of the five operating modes.
There are two methods of setting discrimi-
nation in any mode.
