Sensitivity
MANTICORE is highly sensitive and has an
adjustable Sensitivity setting. Adjusting
the Sensitivity to suit individual detecting
conditions will maximise detection depth.
Sensitivity adjusts the detector’s level of response to
targets and the environment by controlling the amount of
amplification applied to signals received by the detector
(sometimes called 'Rx gain').
Sensitivity is global, and has a range from 1 to 35 with a
default setting of 20.
The Sensitivity Level is displayed on and adjusted from the
Detect Screen.

WHEN TO ADJUST SENSITIVITY
Always choose the highest stable Sensitivity setting to
get the best performance from your detector. Therefore,
before decreasing the Sensitivity setting to eliminate noise,
first Noise Cancel and Ground Balance the detector. Doing
this may resolve the noise problem so you can continue
detecting at the highest possible Sensitivity setting.
RECOMMENDED SENSITIVITY SETTINGS
Some experimentation with the Sensitivity Level may be
beneficial for different detecting locations. For beginners,
start with a low setting and increase it progressively.
Decreasing the Sensitivity may reduce false signals and
interference. This will also improve differentiation between
signals caused by metal targets and soil mineralisation.
EXTREME SENSITIVITY SETTINGS
Some users set the Sensitivity to a high setting (between
31 and 35) with the intent to not miss any targets. This
can be counterproductive, because unless the detecting
conditions are perfect (i.e. completely quiet), increasing the
Sensitivity may cause targets to be masked by noise.

The Sensitivity Level on the Detect Screen
changes to red when an extreme Sensitivity
Level (31 to 35) is selected.
ADJUSTING THE SENSITIVITY LEVEL
Before reducing the Sensitivity, always try to
resolve noise by first performing:
 Noise Cancel (page 57), followed by
 Ground Balance (page 55)
For steps to identify the source of noise, see
"Identifying the Source of Noise" on page 66.
1. Hold the Coil stationary.
2. From the Detect Screen, press () to increase the
Sensitivity Level until false signals occur.
3. Press () to reduce the Sensitivity Level just enough
that the false signals disappear.
4. Sweep the Coil over a clear patch of ground, and reduce
the Sensitivity Level further if there is still some
ground noise.
