The X-Terra detectors are highly sensitive and
therefore have a wide sensitivity adjustment
range. It is important to set the correct
sensitivity level for your detecting conditions.
Sensitivity is the detector’s level of response
to a target and its environment. Real targets
are interpreted as distinct beeps. Interference
or false targets are interpreted as
crackling or
popping noises.
Tiny ferrous junk targets may be detected
when the sensitivity is set to a high level. The
detector will also be affected by minerals in
certain soils and signals from other electric
appliances
.
Some experimentation with the sensitivity
may be required for different areas. For
beginners, start with a low setting and
increase progressively.
Decreasing the X-Terra’s sensitivity may
help stabilise the detector, reducing false
signals and interference, and assisting in
differentiating between signals caused by soil
mineralisation and those of metal targets.
Choose the highest stable sensitivity setting to
ensure the detectors’ optimum performance.
For beach detecting, a setting below 10
may be required. In high trash areas, such
as modern parks, a setting below 6 may
be required, especially when searching for
shallow coins (X-Terra 50 settings).
X-Terra 30
Sensitivity range = 0-10
Factory preset = 6
X-Terra 50
Sensitivity range = 0-20
Factory preset = 12
The highest sensitivity settings,
(7-10 = X-Terra 30)
(15-20 = X-Terra 50)
should only be used in the quietest,
most stable conditions.
