Ground balancing the detector reduces
false detections and enables good targets
to be displayed and heard correctly.
Ground balance settings affect both normal
discrimination detection and pinpoint
operation.
If there is difficulty ground balancing in
an area with the X-Terra 50, try reducing
sensitivity
(pg. 44).
The X-Terra 30 has a fixed ground balance
that allows adequate operation over most
types of soils.
The X-Terra 50 has an adjustable
ground
balance
which helps in compensating
for false signals.
When the detector is unbalanced, it will
detect targets, but it may also register false
detections due to ground mineralisation.
These false detections are displayed as -9
in all metal or two dashes when using the
factory preset patterns. This will cause good
targets to be displayed only briefly and with
clipped sound.
When detecting on the beach, adjusting
ground balance may not give significant
improvements. Try adjusting sensitivity
and altering patterns for best results.
Ground balance range = 0-20
Factory preset = 6
