discrimination will be reduced and some non-ferrous targets will
be recovered as such at shallower depths.
RGB LED Meter
The RGB meter is based on LED technology and provides a
reliable visual discrimination analysis in All-Metal Mode and VCO
Multi tone mode.
The RGB meter indicates only Non-Ferrous targets in three basic
colours - Green, Orange and White/Purple.
The three colours represent three different non-ferrous
conductivity ranges.
Green colour indicates only the lowest conductors, such as Gold
coins and small Aluminium fragments.
Orange colour indicates everything between Lead, Copper and
Bronze.
Purple / White colour indicates mostly Silver targets, which are
the highest conductivity non-ferrous targets found in most cases.
In this colour very large metal targets will also be displayed as
high conductors.
Discrimination
This knob sets the level of the discrimination. Rotating the
Discrimination knob clockwise (from 0 to 10) will INCREASE the
level so that Iron is increasingly not detected (but high settings
will result in the loss of potentially good targets). Generally, the
discrimination level should be set as low as possible; to avoid
masking the smallest and deepest desired targets.
Unlike the Discrimination settings in MP V2 and MP V1, this
control in MP V3 needs to be set so that Iron is removed from the
RGB meter readings. Setting the Discrimination level control to
