Noise Cancel
In many of the locations you will be detecting in, there will be
electrical interference which may cause your detector to
become unstable. NOISE CANCEL is an automatic function on
the Quattro MP where the most stable search channel is found
for the environment you are searching in. It is important that you
select Noise Cancel BEFORE making adjustments to
Sensitivity or Threshold, as an instable environment will lead
you to make unnecessary changes to these other functions. For
this reason a shortcut NOISE CANCEL button (8) is provided on
the main control panel.
You may find that the source of electrical interference may
change during the course of your detecting session, so if your
detector becomes unstable, press the NOISE CANCEL button
again to cancel the interference.
Important: While performing a NOISE CANCEL, it is
important to keep the detector coil motionless, and also
ensure that no metallic objects are moved in close
proximity to the search coil.

Trash Density
The TRASH DENSITY function will enable the user to optimize the
detector for areas that have a LOW or HIGH ferrous trash content.
Use : LOW is the factory preset setting, and will provide the best performance in most areas.
LOW provides the operator with the most precise target ID and allows the operator to create a
discrimination pattern for a specific target that is quite narrow. It also has a slightly better depth
capability in most soil conditions.
Use: HIGH is a specialty setting, suitable for areas with unusually high amounts of ferrous (Iron)
trash, and also areas with highly variable ground mineralization. HIGH setting detects targets at a
faster rate but with less precision, so in areas with a lot of trash, particularly if close together,
HIGH setting is more likely to detect the presence of a "good" target in amongst a number of
rejected targets. In HIGH setting, a greater number of target ID numbers need to be used to reject
a specific target.
