Ground Balance Procedure
In order to achieve good ground balance follow the recommended procedure. The procedure steps through a sequence that
will help you to identify the type of ground you are detecting and its ground noise levels, and then provides the best steps to
manage that noise. Ground is categorised into four types:
`Normal — Ground with very low levels of mineralisation.
`Difficult — Ground that has high levels of mineralisation.
`Conductive — Ground that has high levels of conductivity, often due to high salt content.
`Variable — Ground that has varying levels of mineralisation and/or conductivity from patch to patch.
Quiet ground
1. Quick-Trak
Perform Quick-Trak following the procedure on page 9. This
will help the detector collect as much information about the
ground as possible for an optimum ground balance.
2. Adjust Sensitivity
Adjust the sensitivity level following the procedure
on page 8.
`If the detector is quiet, begin detecting.
`If the detector is still noisy when the coil is pumped up-and-down in the air, then noise is the result of
conductive ground conditions. Continue the steps for conductive ground below.
Conductive ground
3. Change to Double-D coil
Change to the GPX 14 Double-D coil.
4. Quick-Trak
Perform Quick-Trak following the procedure on page 9.
5. Adjust Sensitivity
Adjust the sensitivity level following the procedure on
page 8.
`If the detector is quiet, begin detecting.
`If the detector is still noisy when the coil is swept from side-to-side, then noise is the result of variable ground
conditions. Continue the steps for variable ground below.
Variable ground
6. Change the Ground
Type to Difficult
Change the Ground Type setting to Difficult.
7. Quick-Trak
Perform Quick-Trak following the procedure on page 9.
8. Adjust Sensitivity
Adjust the sensitivity level following the procedure on
page 8.
`If the detector is quiet, begin detecting.
