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 searchcoil
hanging over the edge.
(or better, have a friend
hold the detector, with
the coil off the ground)
b. Keep the searchcoil 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 searchcoil 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
Searchcoil
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
searchcoil 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 searchcoil 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
angles, you may have
encountered multiple objects.
If you are new to the hobby,
you may want to dig all targets
at first. With practice in the
field, you will learn to better
discern the nature of buried
objects by the nature of the
detector’s response.
