Headphone Socket
This is on the underside of the control box and
will accept a standard pair of headphones with a
¼" stereo jack plug. The loudspeaker will be
disabled when a plug is inserted into the
headphone socket. Headphones are particularly
recommended for searching in Non-Motion
mode.

Adjustable Armrest
The armrest is fixed with a screw. Loosening this
with a screwdriver allows the position of the
armrest to be moved back and forwards. Push
the armrest to the position that provides you with
the most comfort for detecting and tighten the
screw.
Using Your Detector
First, switch your detector on by turning the
sensitivity control clockwise. Continue turning
the control until it is at the sensitivity level you
require. Secondly set the desired level of
discrimination.
Remember
discrimination full on your detector will ignore
many valuable targets, for example gold rings
and much modern coinage. When starting out it
is recommended that a medium setting of about
40-50 should be used. This will reject trash
metals such as iron yet still detect all coinage.
The detector will still detect ring pull-tabs and
silver foil. With experience the setting at which
most rubbish is ignored and desired objects are
still found will become apparent. This can only be
determined by trial and error and depends on the
preference of the individual detectorist.
To detect, hold the detector by the handgrip with
your arm in the rest. Lower the search head to
the ground ensuring that it is flat to the ground.
If you feel the length of the shaft or the position
of the armrest are wrong adjust them now.

Keeping the head close and parallel to the
ground, sweep it back and forth in an arc in front
of you. The speed at which you sweep is not
critical but remember that the machine is more
likely to miss targets if you go too fast. Walk
slowly forward as you sweep, allowing the area
searched each time to overlap with that
searched by the previous sweep to avoid missing
targets.
The detector will emit a beep when an object is
detected. The display will also give a target ID
number as described earlier. Repeated sweeps
are recommended to obtain a more accurate
reading.
The object can then be pinpointed either by
pressing the Pinpoint button which switches the
detector to All Metal mode (VK30 only) or by
repeatedly sweeping over it and noting where
the head is when the sound occurs. More
accurate pinpointing can be achieved by
sweeping at 90 from the original direction. The
that
with
the
intersection of the sweeps that produce a beep
is where the object lies.
The target ID system is not infallible. The signals
received from round steel objects, for example a
washer or recent 2p piece, can confuse the
detector. If repeated sweeps over a target give a
wide range of numbers and the number of blocks
shown on the display varies greatly this is the
detectors way of telling the user that one of
these 'problem' objects has been found. The
choice to dig or not is up to the user. Remember
that the display only acts as a guide.
Beach Detection
When detecting on beaches the detector will
produce more false signals especially as you -
near the water's edge. To overcome this, switch
