Double D
This is the best option for areas of medium to very high
mineralisation. It is also excellent for pinpointing, as the target
response is strongest from the centre of the coil.
The search pattern in Double D is the conventional blade or
wedge shaped signal through the centre of the coil.
Mono
This setting may be used in most locations of low to medium
mineralisation. Mono is also suitable for locating small nuggets
with Soil/Timings set to Sensitive Extra in the LCD menu.
Using a Double D coil, running in Mono will often increase
the sensitivity of the detector but may also be a little more
unstable in heavily mineralised ground. Pinpointing (p. 77) is
not centred in the middle of the coil, but to the left side, and
may give a complex signal when the target is very close to the
coil. It is recommended you use the left edge of the coil to
pinpoint shallow targets.
Cancel
This setting provides a receive field that is particularly stable
in areas of electrical interference. This position is ideal for
detecting close to suburbia or where the Tune function
has difficulty selecting a quiet operational channel (e.g.
near power lines, phone towers or under poor atmospheric
conditions).
Pinpointing in Cancel will be to the left side of the coil and
signals may be complex if the target is close to the coil. In
Cancel, sensitivity and depth are slightly reduced. You may be
able to increase Rx Gain (p. 63) if using Cancel.
The detector will not detect targets if Cancel is used with
a Monoloop coil.
Tip: Commander
Monoloop coils can be
used on the GPX Series
with excellent results. For
maximum stability we
recommend their use in
conjunction with the Coil/
Rx switch in Mono.
