Minelab x-terra manual Ground balance range = Factory preset =

50

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.

Ground balance range = 0-20

Factory preset = 6

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).

When detecting on the beach, adjusting ground balance may not give significant improvements. Try adjusting sensitivity and altering patterns for best results.
