To Manage Ground Noise:
Perform a Ground Balance� To achieve the most thorough Ground Balance, follow the full‑length Ground Balance
`
Procedure
(page
17)� To rapidly balance to the ground, follow the Quick‑Trak Ground Balance Procedure
In variable ground, use the Difficult Ground Type setting

Conductive Ground Noise
Conductive soils commonly occur when the soil contains salts� The effects of conductivity are most noticeable after rain when
salts are dissolved in water and become conductive� Ground may be conductive (salty) without any obvious environmental signs�
If a detector is sensitive enough to detect small gold, then it is also likely to detect low levels of conductivity�
To Identify Conductive Ground Noise:
To verify that noise is due to conductive ground, hold the coil 1 metre (3�3 feet) above the ground� Tilt the coil so that it is
parallel to the ground (horizontal) and then raise and lower the coil in the air between knee and shoulder height� If you hear
noise that correlates to the coil movement, then noise is likely due to conductivity in the ground�
To Manage Conductive Ground Noise:
`
Use a Double‑D coil with the Double‑D mode set to Conductive Ground Cancel
