Investigator G-500. Specific "notch" patterns
can be created in Mode B by adding or remov-
ing illuminated segments.
There are two methods of setting discrimi-
nation in Mode B:
First Method: Pass the searchcoil over an
object to be accepted or rejected as a target or,
pass the particular target across the face of the
coil about two inches from its surface. If the
segment is displayed on the Lower Scale of
the GTA, that particular target will be detected.
If you wish to reject that type target, press the
DISC touchpad. The segment will disappear,
creating a "reject notch."
If the Lower Scale segment is not displayed,
press the DISC touchpad to illuminate it, creat-
ing an "accept notch," and your GTA detector
will begin detecting targets represented by that
segment.
Second Method: Press the + and - touchpads
to position the Upper Scale cursor above the
26
Lower Scale segment corresponding to the
particular target to be detected or ignored.
Check to make certain there is an appropriate
cursor on the Upper Scale of the Graphic
Display. Then press DISC depending upon
your discrimination choice for this specific tar-
get.
Note: Discrimination notches you have creat-
ed in Mode B will not affect discrimination in
the other mode. Each time the detector is
turned off your Mode B DISC accept/reject dis-
crimination patterns will be retained. All selec-
tions will be lost when you return your detector
to factory-set detection calibrations by press-
ing and holding the POWER touchpad.
There are numerous reasons why you would
want to accept or reject specific targets:
• You may be looking for only one item D a cer-
tain cartridge, for example. You can program
the Investigator G-500 to reject all other types
of metal targets.
