Ground Balance Procedure
A complete Ground Balance procedure is recommended below� This guides you through
the ideal steps to deal with a number of different ground conditions�
The procedure is a sequence of steps that will help you to identify the type of ground you are detecting, and then provides
the best steps to manage that noise� Ground is categorised into three types:
` Normal — Ground with low levels of mineralisation�
` Difficult/Variable — Ground that has medium to high levels of mineralisation, or varying levels of mineralisation and/or
conductivity from patch to patch�
` Conductive — Ground that has high levels of conductivity, often due to high salt content�
START `
Normal (Quiet) Ground `
1. Set the Ground Type to Normal.
2. Quick‑Trak.
3. Adjust the sensitivity.
` Begin detecting.
` If the detector is still noisy when detecting, continue the steps below for difficult/variable ground.
Difficult/Variable Ground `
4. Set the Ground Type to Difficult.
5. Quick‑Trak.
6. Adjust the sensitivity.
` Begin detecting.
` If the detector is still noisy when detecting, then noise is the result of conductive (salty) ground conditions�
Continue the steps for conductive ground
CONTENTS
Set the Ground Type to Normal by pressing the
Ground Type button�
Perform the Quick‑Trak procedure
the detector collect as much information about the ground as
possible for an optimum ground balance�
Adjust the sensitivity level
Swing the coil close and parallel to the ground when adjusting
the sensitivity in order to remove ground noise�
Set the Ground Type to Difficult by pressing the
Ground Type button�
Perform the Quick‑Trak procedure
Adjust the sensitivity level
Swing the coil close and parallel to the ground when adjusting
the sensitivity in order to remove ground noise�
