Ground Suppressor
It is used to eliminate false ground signals in tough
terrains. If you think your device is noisy and you are
getting false signals and cannot get rid of them by
dropping the sensitivity to 25, first set your sensitivity
back to where it was. Then increase the Ground
Suppressor gradually until you get rid of the noise. As
the value is increased, the sensitivity of the device will be
less to high conductors (silver, copper etc.).
Ground Suppressor setting cannot be used in the All
Metal mode and thus cannot be selected.
Ground Suppressor setting is set to 5 in the Beach
mode and to 0 in the other modes by default. It is
recommended to use this setting at the minimum levels
if you are not getting noise from the ground.
To use this setting, after accessing the settings menu,
use the right and left buttons to select the Ground
Suppressor setting and adjust it by the plus (+) and
minus (-) buttons.
