Testing the detector
Test your detector using different coin types (penny, nickel, etc.) and
other miscellaneous metal objects such as a nail, a gold ring, a railroad
spike, etc. Always test the detector away from other metals not selected
for testing.
▲
Ground Testing
Do not test the unit indoors on the floor because floors usually contain
metal that may interfere with the detector’s signal or even mask the
signal completely.
◆
In
DISCRIMINATION
or
PRESET
mode, you must move the
search coil over the object—do not move the coil too quickly over
the object and keep the coil 1/2” above the ground when
sweeping.
◆
In
ALL METAL
mode, movement of the search coil is not
required—hold the coil over the object and 1/2” above the
ground.
▲
Air Testing
Follow these steps to test your detector as it lays stationary and you
pass objects over its search coil, as illustrated in the following diagram.

the objects you selected for testing across (and about 4” from) the
coil.
