TROUBLESHOOTING
If the detector emits a false signal when in use:
• Sensitivity set too high? Reduce the
sensitivity until the false signal stops.
• Move the search coil slowly.
• Oxidised metal can cause false signals.
• If the signal is not repeated when the search
coil is moved over the target area then the
target usually consists of scrap metal.
If the display indicated several target
categories, or there are several audio
signals at the same time:
• More than one type of metal is present, or
the detector cannot identify the target.
• Can also be caused by oxidised metal.
• Another common cause is high sensitivity.
The detector is unstable and gives false
indications:
• There could be power lines or another
metal detector in the vicinity.
coil is moved, but how the machine is adjusted.
The machine does not adjust automatically to
varying environmental conditions, but must be
adjusted by the user.
Adjusting
Hold the search coil still just over the ground.
The selected area must not contain any metal
objects. Move the search coil repeated over
the area to ensure that it does not indicate the
presence of any metal.
Detection range
The detection range depends on the size of the
target object.
Large objects
When an object is detected the sensitivity
(SENSITIVITY) is shown on the display and an
audio signal is heard. If the signal does not
become weaker when you lift the machine
about 2 cm over the ground then a large or
irregularly shaped object has been detected.
Lift the search coil higher. The indication on the
display becomes reduced and the signal quickly
becomes weaker. Localise the edges of the object
with slow movements at the same height.
Small objects
When an object is detected low sensitivity
is shown on the display and a weak audio
signal is heard. Hold the search coil at the
same height over the ground and move it
from side to side. Note the point where the
signal is strongest and the highest sensitivity
is indicated. Usually the sensitivity indication
changes more than the audio signal. Bring
the search coil closer the ground to precisely
locate the target object. Coin sized objects are
detected when they come within the inner
range of the coil. Care and maintenance For
best results follow the maintenance instructions
for safety, functionality and useful life.
