The X-terra 70 is capable of operating
in two different types of grounds,
magnetic (ie. inland parks) and
conductive (wet areas of salt water
beaches). Ground mineralisation
may cause false target signals in all
environments. Ground Balancing
the detector reduces these ground
signals and enables good targets to be
displayed and/or heard correctly.
Ground Balance (Normal)
Ground Balance (Normal) is suitable for
inland use and is operating when the
beach icon is off.
An unbalanced detector in Coin &
Treasure Mode will blank continuously
(if a pattern rejecting –8 is used) or
detect –8 continuously (if a pattern
accepting –8 is used).
An unbalanced detector in Prospecting
Mode will produce a continuous
‘warbling’ sound that differs from the
sharper sound of a real target signal.
Ground Balance (Beach)
Ground Balance (Beach) is suitable for
salt water beach use and is operating
when the beach icon is on.
In Ground Balance (Beach) the X-Terra
70 can Ground Balance any combination
of magnetic and conductive soil (e.g.
a mixture of sand, soil and salt water).
However, ferrous and some low
conductivity targets can be balanced
out. For this reason in Ground Balance
(Beach), Tracking should be used only
when targets are far apart.

Try reducing Sensitivity (pg. 30)
before Ground Balancing.

Ground Balance may not give signifi cant
improvements. Try adjusting Sensitivity
and altering Patterns for best results.
