10. Detector Sounds
Start –up music. When you first turn the detector on, there is a short tune during the detectors
‘start-up’ sequence. Wait until this tune has finished before pressing other buttons or starting
to detect.
Threshold. This is the slight background ‘hum’ which is there during detecting.
Target Signal. This is the signal given by the detector when a metal target is located and not
discriminated out.
Conductivity Tones. When searching in the COIN or COIN/JEWELRY mode, the target signal
will vary depending on the conductivity of the metal the target is made from. If the target is made
from a highly conductive metal, the tone of the signal will be higher pitch, if the target is low
conductive, the tone of the signal will be of a low tone.
Ferrous Tones. If searching in RELIC or ALL METAL modes the target signal will vary depending
on the ferrous content of the target. If the target has a high ferrous content like pure iron, the tone
of the signal will be a low pitch, if the target has a low ferrous content, the tone of the signal will
be of a higher tone.
Null. If you pass across a target which is discriminated out, you will notice that the threshold will
momentarily go quiet and return again once you have passed the target.
Pinpoint. Passing across a target in pinpoint, the target signal is quite short and ‘clipped’ in its
response.
Overload. If passing across a large or shallow target, the detector will give a continuous buzzing
sound indication the target signal is too strong to interpret.
Low Battery Signal. When the battery power is exhausted, there will be a short tune and
shortly after a longer tune will announce the detector is switching off.
11. Using Your Quattro MP
Sweeping the Coil
The Minelab Quattro MP will perform at its best when
the coil is kept close to the ground. This will increase
detection depth and response to small objects.
Becoming practised at sweeping the coil is very
important, as a variation in coil height at the end of
each swing can cause confusing sounds and reduce
detection depth. Each sweep of the coil should slightly
overlap the last one. This will ensure thorough ground
coverage.
When an object is detected, the Minelab Quattro MP
emits an audio response and visually displays a target
classification on the LCD.
