SENSITIVITY
The VANQUISH Series detectors are highly sensitive and have
adjustable sensitivity� Setting the correct sensitivity level for
individual detecting conditions will maximise detection depth�
Always choose the highest stable sensitivity setting to ensure
optimum performance�
The Sensitivity Level indicator on the display shows the
current Sensitivity Level� Each bar represents one level�
The Sensitivity Level indicator (540 shown) showing
maximum sensitivity (level 10)
To Adjust the Sensitivity Level
1� Hold the coil stationary, then use the Sensitivity Plus
button to increase the sensitivity until false signals begin
to occur�
The Sensitivity
adjustment buttons
2� Reduce the sensitivity level by pressing the Sensitivity
Minus button, just enough that the false signals
disappear�
3� Sweep the coil over a clear patch of ground, and reduce
the Sensitivity Level further if any ground noise is
encountered�
Excessive Noise
Sometimes, excessive noise is encountered whilst detecting�
This can be caused by environmental electromagnetic
interference (EMI) from sources such as power lines, mobile
phone towers, or other metal detectors�
If noise is a problem, try the following steps in order until the
noise is eliminated�
1� Move away from local sources of Electromagnetic
Interference (EMI)�
2� Restart the detector, and wait for the automatic Noise
Cancel process to complete�
3� If restarting the detector does not eliminate the excessive
noise, then try reducing the Sensitivity Level�
Automatic Noise Cancel
VANQUISH Series detectors have an automatic Noise
Cancel process that occurs every time the detector is
powered on� It calibrates the detector so that excessive
noise is not experienced�
For best results, the coil should be held stationary just
above the ground until Automatic Noise Cancel is complete
(indicated by two large dashes displayed on the Target ID
Number field)�
IRON BIAS
The Iron Bias feature is set to High by default, allowing
the detector to correctly classify large or complex ferrous
targets, such as rusty nails or bottle crown caps, as ferrous,
which can be more easily rejected�
The VANQUISH 540 allows the Iron Bias level to be set to
Low� This allows the detector to better identify coins amongst
dense ferrous trash�
Set Iron Bias to Low (540 only)
The VANQUISH 540 Iron Bias is returned to its default setting
each time the detector is powered on�
1� Long‑press the All‑Metal button for approximately 2
seconds�
The All‑Metal button
(long‑press for Iron Bias)
2� The Iron Bias Indicator will appear on the display to the
left of the Target Identification Number to indicate that
Iron Bias is set to Low�
The Iron Bias Indicator
3� To return the Iron Bias setting to High, Long‑press the
All‑Metal button for approximately 2 seconds� When Iron
Bias is set to High, The Iron Bias indicator is off, and no
icon is displayed�
