18 Garrett Metal Detectors
you may want to use the manual Ground Balance function
to ground balance slightly positive to enhance detection of
small targets or balance slightly negative to reduce detection
of "hot rocks," terra cotta, clay bricks and saltwater.
Typical Ground Balance Ranges:
80–99: Highly ferrous (magnetite, ferrous oxide minerals,
black sands, hot rocks, terra cotta)
60–80: moderately mineralized soils (red clay, brown clay,
iron-bearing clay minerals, etc.)
20–60: Likely an iron object
0–20: Highly conductive, non-ferrous minerals such as
saltwater
