Ground Balance - Minelab EQUINOX 600 Instruction Manual

Ground Balance

Ground Balance reduces noise caused by ground mineralisation, allowing good targets
to be detected more clearly.
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 for all Park, Field, and Beach Mode search profiles.
Tracking Ground Balance is the recommended and default ground
balance method for Gold Mode.
Ground Balance adjustment is local; only the current Detect
Mode Search Profile will be affected by changes to this setting.
Manual Ground Balance
Ground Balance can be manually adjusted until the minimum
amount of ground signal is heard.
1. Press the Settings button to navigate to the Ground Balance
setting in the Settings Menu.
2. Raise and lower the coil repeatedly over a clear patch of soil
that does not contain any targets.
Listen to the audio response to interpret the result of the
Ground Balance; a low tone indicates that you should increase
the Ground Balance value and a high tone indicates that you
should decrease it.
3. Press the Minus (–) and Plus (+) buttons to manually change
the Ground Balance value until the minimum amount of
ground signal is heard. The Manual Ground Balance value is
shown on the Target ID Display.
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.
Using Auto Ground Balance is the recommended Ground Balance
Method.
1. Press the Settings button to navigate to the Ground Balance
setting in the Settings Menu.
2. Press and hold the Accept/Reject button throughout the Auto
Ground Balance process.
The Tracking Ground Balance icon on the LCD will
begin to flash rapidly.
3. Raise and lower the coil repeatedly over a clear patch of soil
that does not contain any targets. Observe the Ground Balance
value updating dynamically on the Target ID Display, as the
audio reduces in response to the ground.
4. The response will be stabilised when the value in the Target ID
Display settles on a single value.
5. Release the Accept/Reject button.
The default Ground Balance setting of 0 is
recommended for Park, Field and Beach Modes
because these locations typically have less
mineralisation than goldfields.
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.
