Track
Tracking Ground Balance follows the
changes in ground conditions and constantly
adjusts the Ground Balance while detecting.
As Tracking Ground Balance constantly
updates the Ground Balance automatically,
repeated passes over a target may result in
the detector balancing to the target instead
of the ground, diminishing the target signal.
It is recommended that Tracking Ground
Balance is toggled off when a target is
detected.

Balance.
While Tracking Ground Balance is activated,
the Tracking icon and current Ground
Balance value will be displayed. The setting
scale will also become animated.
