Salt Mineralisation
Salt content in the ground causes a negative
(–) response rather than the positive (+)
response of laterite soils.
A large salt content in the ground will have
a different effect on the detector than other
types of mineralisation. Therefore the detector
needs to use different filtering techniques to
overcome this effect.
Search Coil
The search coil is the circular plate which
is swept across the ground surface during
detecting. It transmits electromagnetic signals
into the ground and receives the response.
Search Pattern
The search pattern is the area of ground
underneath the coil which is being scanned.
Depending on the style of coil (Double D
or Monoloop) and the Coil/Rx setting being
used (Double D/Monoloop/Cancel), different
coils will have a different shaped area being
covered by each sweep.
Threshold
The continuous audible level of sound
emitted by the detector is referred to as the
Threshold. Threshold can be set anywhere
between silent and loud; but a soft audible
level is normally suggested.
Target Signal
This is a change in the tone (pitch) and volume
of the Threshold when a target is detected
and not discriminated (rejected).
Tracking
The function of automatic Ground Balance
where the detector makes continuous
adjustments to the Ground Balance to
compensate for changes in the mineralisation
of the ground.
Tx (Transmit)
This refers to the transmit signals or
electromagnetic pulses, sent into the ground
by the coil.
The GPX Series are high quality, electronic
instruments. Take care of your detector in the
following way:
The control box is water resistant but not
waterproof. Keep all electrical connectors
clean and dry.
The coil may be used in light rain but take care
not to immerse it in water.
The control box and coil should not come into
contact with petrol or other oil-based liquids.
Regularly remove loose dirt and dust from
the control box using a dry paint brush. Clean
the detector shaft and coil with a damp cloth
using a mild soap detergent.
Do not use solvents.
The coil housing will eventually wear
through if you scrub the ground with it while
searching. Use of a replaceable skid plate will
help to protect your coil. Regularly replace
such items as coil washers and skidplates to
increase the life of your detector.
To prevent dirt entering between the coil and
the skidplate, silk tape (e.g. Leukosilk®) may
be used. Silk tape can be found at your local
chemist or drug store. The use of some other
carbon based tapes, e.g. insulation tape, may
result in some loss of sensitivity.
Do not expose the detector to high
temperatures or leave it in the sun for longer
than is necessary. Shading will help protect it.
Do not leave the detector in a closed vehicle,
especially in the sun.
Do not open the control box as this will void
your warranty. All control box, battery and coil
repairs should be sent back to Minelab or a
Minelab authorised repairer.
Travelling with your detector
If you plan on travelling by air, please be aware that certain
airlines have restrictions on the transport of Li-ion batteries.
