Discrimination Pattern
Rejected Targets
Discrimination is the detector's ability to
eliminate signals from undesired targets
and accept signals from desired targets.
Each coordinate of the Smartfind
window can be turned white or black
to accept or reject certain targets,
respectively.
White (clear) pixels indicate that those
particular targets are accepted. Black
pixels indicate that those particular
target signals are rejected.
The combination of rejected and
accepted pixels is referred to as a
'Discrimination Pattern'.
The Pattern shown above is the default
Discrimination Pattern of the Explorer
SE. It accepts signals from non-ferrous
coins and rejects signals from most
high-ferrous targets.
Accepted Targets
When an accepted target is detected
(matching the conductive and ferrous
characteristics of coins), the Target
Crosshair will appear in the white (clear)
area of pixels and a target response will
sound.
When a rejected target is detected (not
matching the conductive and ferrous
characteristics of coins), the Threshold
will blank and the Target Crosshair
will remain in the position of the last
accepted target.
Explorer SE offers a range of
Discrimination Patterns which may be
used on their own or in combination.
(Select, pg. 40)
The default Discrimination Pattern
represents the typical characteristics
of non-ferrous coins, a composite of
hundreds of coins from around the world.
Changing Discrimination Patterns
The Explorer SE has four different ways of
changing the Discrimination Pattern to
find only the types of targets you want:
Reduce or increase the amount of ferrous
signals with Iron Mask (pg. 34).
Use a target that you have previously
found to create a Discrimination Pattern
with the LEARN feature (pg. 44).

Select from a preset list of Discrimination
Patterns that correspond to common
desired and undesired targets (pg. 40).
Manually Edit areas of the Discrimination
Pattern (pg. 50).
