Move it around slightly, and maximum sound
will be heard when the target is directly
beneath the center of your searchcoil. This
increase will be further reflected in the Upper
Scale of your Graphic Display. Illumination of
the scale's segments, from right to left, will indi-
cate how close you are to your target.
For most effective electronic pinpointing place
the searchcoil on the ground directly above
your target. Press and hold the PINPOINT
touchpad. Scan back and forth across the tar-
get, maintaining searchcoil contact with the
ground. You will notice an even more distinct
audio sound when the target is directly
beneath searchcoil center.
You can also watch the Upper Scale illuminate
from right to left to indicate signal strength.
Maximum reading attained toward the left will
indicate exact target location.
Depth Measuring

Recovery
Locating your target precisely will enable you
to recover it quickly by digging the smallest
hole possible. This is accomplished first by pin-
pointing. You can then utilize another function
of the Investigator G-500 for measuring depth.
Pinpoint targets by first drawing an imaginary
"X" on the ground with the searchcoil at the
place where maximum sound occurs. You'll
notice that the searchcoil must be moving
slightly and that you cannot maintain detection
sound with the searchcoil held completely still
above your target. This is called Manual
Pinpointing, and it is satisfactory for many
operators.
There is another more exact method of pin-
pointing, however...
Electronic Pinpointing
Precise pinpointing is an important capability of
your Investigator G-500. When you press and
hold the PINPOINT touchpad, the searchcoil
can remain steady, directly over your target.
