BENCH TESTS
You should conduct bench tests to become more familiar
with your detector’s operation� To conduct a bench test:
1� Place the searchcoil on a flat, non-metallic surface that is
several feet from other metallic objects�
2� Select the ZERO-DISC mode�
3� Pass various metal objects (coins, bottle caps, nails, etc�)
across the searchcoil at a distance of 8 to 10cm� Your
metal detector will audibly and visually identify the target�
4� Perform this test in all the modes available on your
detector� Observe the sounds
as well as the graphics on
the LCD that are made in
each mode�
5� Record the results of your
bench tests and refer to them
when hunting in the field�
Once you have determined how your test targets register
on the Target ID during bench tests, test them in the soil� Bury
your targets at recorded depths to create a "test plot�" Note
how various targets read based upon whether they are lying
in the ground flat or at various angles�
Keep accurate records or surface markers to indicate your
test plot targets and their depths� Try testing these targets
again in several months after the ground has settled, during
periods of extreme drought or after a soaking rain� Take note
of any changes in how these targets are detected�
• If you are new to metal detecting, start searching in areas
with sandy and loose soil to make it easier to learn how to
use your metal detector, pinpoint and dig targets�
• Keep your searchcoil height about 2–3cm above and
parallel to the ground at all times for best detection results�

CORRECT
SWING
INCORRECT
SWING
• Swing your searchcoil parallel to plow lines and the
water's edge� This will minimize the negative effects
caused by uneven ground in plowed fields and varying
amounts of moisture near the water� Do not swing the
searchcoil perpendicular to plow lines and the water's edge,
as this may produce abrupt changes in ground response
that can reduce the detector's performance�
• Walk slowly as you scan your searchcoil in a straight line
from side to side at a speed of about 1 meter per second�
Advance the searchcoil about half the length of the
searchcoil at the end of each sweep�
