Sensitivity; Extreme Sensitivity Settings; Adjusting The Sensitivity Level; When To Adjust Sensitivity - Minelab MANTICORE Instruction Manual

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:

For steps to identify the source of noise, see
"Identifying the Source of Noise" on page
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�
