Bench Testing - Garrett Investigator G-500 Owner's Manual

• You may be hunting in an area where you are
plagued with a specific type of trash. You can

to hunt with no other discrimination, detecting
all other metal.
• Just make certain that a potential target does
not fall within any trash segment you have cho-
sen for elimination.

BENCH TESTING

This technique will enable you to test typical
metallic items and to learn about the discrimi-

ably wooden, surface with the searchcoil at
least three feet away from all metal. Make cer-
tain you are wearing no rings or jewelry on
your hands or arms that could be detected.
Turn the detector on and adjust the audio con-
trol for threshold sound. The following tests
should be performed with the searchcoil per-
pendicular to the bench:
