QUICK-START DEMONSTRATION
I. Supplies Needed
• A Nail
• A Quarter
•
A Pull-Tab from a beverage can • A Zinc Penny (dated after 1982)
• A Nickel
II. Position the Detector
a. Place the detector on a
table, with the search coil
hanging over the edge.
(or better, have a friend
hold the detector, with
the coil off the ground)
b.
Keep the search coil
away from walls, floors,
and metal objects.
c. Remove watches, rings and other jewelry or metal objects from
hands and wrists.
d. Turn off appliances or lights that cause electromagnetic interference.
e. Pivot the search coil back
toward the detector body.
III. Power Up
Turn Ground Balance knob to
pre-set position.
Press the POWER touch pad.
IV. Wave each Object over the
Search Coil
a.Notice a different tone for each object.
Bass Tone:
Nail
Low Tone:
Pull-Tab
Medium Tone:
Zinc Penny
High Tone:
Quarter
b.Motion is required. Objects
must be in motion over the
search coil to be detected.
V. Press the DISC A-M touch pad
The detector will beep twice
and 3 “R”’s will appear
under the iron indicators.

Swing the search coil slowly,
overlapping each sweep as you
move forward. It is important
to sweep the coil at a consistent
speed over the ground as you
search. After identifying a
target, your sweep technique
can help in identifying both the
location and the nature of the
target. If you encounter a weak
signal, try moving the coil in
short, rapid sweeps
over the target zone;
such a short rapid
sweep may provide
a more consistent
target
identification.
Most
worthwhile
objects
will
respond with a repeatable tone.
If the signal does not repeat
after sweeping the coil directly
over the suspected target a few
times, it is more than likely
trash metal.
Crossing the target zone with
multiple intersecting sweeps at
multiple angles is another way
to verify the repeatability of the
signal, and the potential of the
buried target. To use this
method, walk around the target
area in a circle, sweeping the
coil across the target
repeatedly, every 30 to 40
degrees of the circle, about ten
different angles as you walk
completely around the target.
If a high-tone target completely
disappears from detection at a
given angle, chances are that
you are detecting oxidized
ferrous metals, rather than a
silver or copper object. If the
tone changes at different
