IN THE FIELD TECHNIQUES
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.

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 a different angles,
ASSEMBLY
Assembling your Challenger Metal Detector is easy
and requires no tools. Just follow these steps:
G
1
Using the supplied bolt and knurled knob,
attach the search coil to the lower
stem.
G
2
Press the button on the
upper end of the lower
stem and slide the
lower stem into the
upper stem.
Adjust the stem
to a length that lets
you maintain a comfortable upright posture, with your arm
relaxed at your side.
Maintain the search coil
about 1 inch above the
ground as you sweep.
G
3
Wind the search coil cable
around the stem. Leave enough slack in the cable to let you
adjust the coil when you are hunting on uneven ground. Then
tighten the knob at the end of the search coil.
Note: To adjust the coil,
simply loosen the knob.
G
4
Insert the coil's plug into
the matching connector on
the control housing. Be
sure the holes and pins
line up correctly.
Caution:
Do not force the
plug in. Excess
force will cause
damage.
To disconnect the
cable, pull on the
plug. Do not pull
on the cable.
