Ground Balance Type
General
This is the best Ground Balance Type for use in over 90% of
goldfield soils and uses the conventional automatic Tracking
as found on the previous Minelab models. In Tracking,
General Ground Balance (GB) samples variations in the ground
mineralisation and sets a continuously changing average
of the Ground Balance level. General GB is ideal for most
mineralised grounds and is the preferred Ground Balance Type
for soils which have highly variable mineralisation.
Specific (GPX 5000)
This is a special Ground Balance Type for use in areas of highly
magnetic, iron-rich soils. Use of Specific GB will allow you
to keep the coil closer to the ground, and allows Monoloop
coils to be accurately ground balanced in areas normally too
‘hot’ for their use. The Tracking function in Specific is more
conservative than in General, and will pause on even the
faintest response, removing the risk of 'Tracking out' faint
signals.
It is recommended that you be more active in checking
your GB setting when using Specific in variable soils. Stop
periodically, raise and lower the coil, listen to any variations
and re-ground balance where necessary. Ideally, Specific GB
should only be used in soils that are reasonably uniform or
non-variable.
Note: A different Ground Balance Procedure is required when
using Ground Balance Type Specific. See Ground Balance
Procedure for Specific, p. 56, for more information.
