Ground Balance
The Ground Balance setting calibrates the
detector to the local ground in order to
eliminate the false signals caused
by mineralisation.
The Ground Balance setting has a range from
−9 to 99, with a default of 0 (zero) for all Search Modes.
Tracking Ground Balance is the recommended and default
ground balancing method for Beach Surf & Seawater mode
and Goldfield General mode.
Ground Balance adjustment is local; only the current
Search Mode is affected by changes to this setting.
You can assign Auto/Tracking Ground Balance as a
Soft Key Action — see page 35.
Ground Balance in the
Settings Menu.
The default Ground Balance setting of 0 (zero) is
recommended for All-Terrain modes because these
locations typically have less mineralisation than gold
prospecting locations.
However, if the ground is generating many noise signals
(and/or the Sensitivity Level is set very low), then using
Auto Ground Balance is recommended.
If the Auto Ground Balance process does not greatly
reduce ground noise (due to highly mineralised ground
or high salt levels), then repeat the Auto Ground Balance
process by sweeping the Coil from side-to-side, rather
than the standard up-and-down motion.
AUTO GROUND BALANCE
With Auto Ground Balance, the detector automatically
determines the best Ground Balance setting after the
balancing process is initiated by the operator.
Auto Ground Balance is the recommended
Ground Balance Method.
When using Beach Modes, Auto Ground Balance is
strongly recommended for best performance.
Auto Ground Balance Procedure
1. Navigate to Ground Balance:
