sensitivity
The X-Terra 705 is highly sensitive and has
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
indicated by distinct beeps and should stop if
the coil is held stationary. Interference or false
targets are interpreted as crackling or popping
sounds and generally continue when the coil is
held stationary.
Tiny ferrous junk targets might 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 electrical
appliances.
Some experimentation with the Sensitivity
scale may be required for different areas. For
beginners, start with a low setting and increase
it progressively.
Decreasing the Sensitivity of the X-Terra 705
may stabilise the detector, reducing false
signals and interference, and assisting in
differentiating between signals caused by soil
mineralisation and those of metal targets.
Always choose the highest stable Sensitivity
setting to ensure optimum performance. Do
this by holding the coil stationary; increase the
Sensitivity until the detector becomes unstable;
then reduce the Sensitivity by one or two
settings until it is stable.
For beach detecting, a setting below 15
may be required. In high trash areas, such
as modern parks, a setting below 9 may be
required, especially when searching
for shallow coins.
