Testing and fitting of batteries
Set the VOLUME button (4) to its centre
position.
Push the OPERATE/BATT TEST button (11) to
the BATT TEST position.
If you cannot turn the metal detector on,
or the needle on the VU meter (5) is not in
the green field between the 3 and 6 marks,
replace the batteries.
Turn the VOLUME button to the OFF
position so that it clicks.
Push the battery cover and slide in the
direction of the arrow.
Remove the old batteries and insert 6 new
1.5 V AA alkaline batteries.
Ensure the battery poles match the
markings in the battery compartment.
Replace the battery cover.
Preparation for use
Loosen the adjustment knob (8) for the
search coil and tilt the search coil so that
it is parallel with the ground when you are
standing with the metal detector in working
position. Tighten the adjustment knob.
Loosen the adjustment knob (6) on the
shaft and adjust to the required length.
Tighten the adjustment knob.
The search coil should be 1-5 cm above the
ground.
About the metal detector
The metal detector’s search coil, together
with its controlling electronics, can detect
objects made of iron or ferrous metals, as
well as objects made of non-ferrous metals
such as gold, silver, copper, platinum,
aluminium, lead and zinc, when it is moved
slowly over the metal object.
No metal detector is 100% accurate, and
its effectiveness depends on, among other
things:
• The angle of the metal object in relation
to the search coil.
• How deep the metal object is buried.
• The amount of iron in the metal object.
• The size of the metal object.
• How rusty the metal object is and
whether there are rust particles in the
ground around the object.
Adjusting the transmitter and
receiver
Start by matching the metal detector’s
transmitter and receiver to one another so
that any fluctuations on the VU meter and in
the sound produced are consistent.
Push the OPERATE/BATT TEST button (11) to
the OPERATE position.
Switch the metal detector on by turning the
VOLUME button to the 11 o’clock position
and setting the DISCRIMINATION button
(10) to its centre position.
Hold the search coil around 30 cm above
the ground at a suitable distance from
metal objects.
Press the red reset button (3) and slowly
turn the TUNE button (2) clockwise or
anticlockwise until the needle is at the 0
mark on the VU meter. Now release the red
button.
