Testing indoors
Remove your watch, any rings, etc., so you
are not wearing any metal objects.
Put the metal detector on a table and tilt
the search coil, so it faces upwards.
Switch the metal detector on by turning the
VOLUME button to the 11 o’clock position
and setting the DISCRIMINATION button to
its centre position.
Run a metal object across the search coil in
a steady motion, approximately 5 cm above
it.
If using a coin, the flat surface must face the
search coil.
When the metal detector detects the object,
the sound changes, and the VU meter
needle will move to the left for ferrous
metals or to the right for non-ferrous
metals.
Testing outdoors
Choose a place where you are sure that
there is no metal in the ground.
Position the metal object you want to use as
the test object – remember where you put it
or dig it down so that you can find it again!
Turn the VOLUME button to the 2 o’clock
position.
Press the red reset button.
Turn the TUNE button until the needle
points to 0 and almost no noise can be
heard.
Hold the search coil 2-5 cm above the
ground, and move it slowly from side to
side over the area where you hid the metal
object. The distance between the search coil
and the ground must be constant.
When the metal detector detects the object,
the sound changes, and the meter needle
will move to the left for ferrous metals or to
the right for non-ferrous metals.
Adjusting the discrimination
Once you become familiar with how the
metal detector works, you can adjust its
ability to distinguish between ferrous and
non-ferrous metals, so you will have fewer
false results when detecting. First, the metal
detector ignores tinfoil, then thicker metal
foil and finally metal objects such as ring
pulls from beer and soft drink cans, as the
DISCRIMINATION button is turned farther
clockwise.
Connecting headphones
If you connect headphones to the metal
detector using the socket on the side
of the control box, the built-in speaker
automatically turns off. This saves power
and you can more easily hear fluctuations
in volume when searching with the metal
detector.
Do not turn the volume up too high, as you
may damage your hearing!
