SETTING DISCRIMINATION
(Selecting Notches)
Many investigators will never require any type
of discrimination. They will be searching for all
metallic targets that might prove to be evi-
dence or looking for any metallic object that
might turn out to be a buried weapon. Still, this
detector offers precise controls that enable an
operator to tailor a detection mode to his or her
specific requirements by setting accept/reject
"notches."
The Lower Scale of the Graphic Display con-
tains 24 segments. Those that are illuminated
(or, displayed) represent conductivities of the
targets that will be detected (with an audible
signal sounded) in the individual operating
modes.
In Mode A, for instance, all 24 segments are
shown, which indicates that every metal target
will be accepted and recognized by the
Additional Information
Any personal preference adjustments you
have set in the Investigator G-500 with the var-
ious operating functions will be retained when
the detector is turned off. Because ground
and/or atmospheric conditions can vary from
place to place, it may be necessary for you to
readjust DEPTH (Sensitivity) occasionally.
Remember!
You can restore instantly the precise factory-
set levels of all its controls. Just hold down the
POWER touchpad for approximately ten (10)
seconds until you hear a "beep."
HEADPHONE JACK
The headphone jack on the Investigator G-500
is located at the rear of the removable battery
pack under the armrest. Headphones are a
valuable accessory for any metal detector to
mask interference from outside noise. They
permit you to hear small and deep targets that
might be missed when using only audio from
the detector speaker. Headphones are particu-
larly essential when you are hunting where
