Most soil types gives a phase reading of around -87.0. Wetlands can produce higher
phase readings (e.g. -83.0). On soils with high conductivity (where the phase readings are
significantly more than -87), working at high sensitivity may be difficult – the sensitivity in this
case should be reduced. Should the ground balance results be noticeably higher than these
values (e.g. -75.0), there is a high probability that some metal objects are present in the balance
area. The ground balance should be repeated again at a different location a few metres away.
NOTE: If you wish to use the detector with the factory presets, pull the trigger after the main
ground balance screen is displayed. This is very useful if you want to find a clean place quickly,
so that you can perform the ground balance process correctly using the
„
pumping” technique.
A single ground balance process does not guarantee stable operation across an entire
search area or for the whole of a day's searching. It is best to repeat a ground balance process
each time a new area is started or when the detector starts to give false readings. Examples of
new areas would be where field changes to forest, or when moving from a track to wetlands.
The detector will also require a ground balance check when either the program, the
frequency or the hot rock parameters are changed.
NOTE: While data is being prepared for work (« Preparing Data » screen) the search coil must
be raised a minimum of 0.5 m above the ground and away from metal objects. Ground balance
must be done at least 15 m away from other detectors. Not following these guidelines will not
damage the detector, but it will cause the detector to operate less accurately – a proper ground
balance procedure will fix this quickly.
The picture below shows the display in the operation mode.
