GROUND FILTERING

4
MIN MAX
Tips - Metal detectors are
often described or catego-
rized by the amount of
electronic filtering used to
distinguish between the
ground, trash, and valued
metal alloys. Typically the
fewer the filters, the quicker
the metal detector can
respond between several
metals targets close to
each other. However,
detection depth in mineral-
ized ground quickly dimin-
ishes with fewer filters.
Audio discrimination
sounds are not as pro-
nounced with reduced
filtering. The more the
electronic filters the better
the detection depth in
mineralized ground and
audio discrimination
becomes more pro-
nounced. However, more
filters equals slower
responses and several
targets near each other
become difficult to sort out
or respond separately.
Settings from 2 - 6 are
available.

21. Ground Filtering
(High Pass Filters or
Differentiators)
GROUND FILTERING is adjustable with the
DFX. The first two primary filters are contained
within the hardware (electrical parts). The remain-
ing filters are contained within the computer soft-
ware allowing full user adjustment.
The DFX GROUND FILTERING has an adjust-
ment range from 2 through 6. At a setting of 2
SWEEP SPEED is not adjustable (fixed).
Selection of 2 filters allows for the best perfor-
mance in high trash areas of medium to low ground
mineralization. Combined with the RECOVERY
SPEED, and BOTTLECAP REJECTION the DFX
will pull some good targets from previously heavy
hunted high trash areas.
Selection of 3 filters will allow for better depth
performance than 2 in slightly higher ground miner-
alization.
Selection of 4 filters allows for the traditional high
end White's filtering ideal for medium to high
mineralized ground.
Selection of 5 or 6 filters allows for new levels of
filtering for extreme ground conditions. Although
some models have been described as having 6
filters in the past, two of those six were dedicated to
visual indications alone. The DFX 6 filter selection
dedicates all six to ground rejection, discrimination,
and audio detection. For those who search extreme
mineralized ground conditions the DFX with its
multifrequency salt/conductive mineral cancelation
and new levels of ground filtration will provide for
performance levels never before available.
