21. Ground Filtering

(High Pass Filters or

Differentiators)

(Discrimination section)

Tips -

Metal detectors are

often described or cat-

egorized by the amount of

electronic ﬁ ltering used to

distinguish between the

ground, trash, and valued

metal alloys. Typically the

fewer the ﬁ lters, the quicker

the metal detector can

respond between sev-

eral metals targets close to

each other. However, de-

tection depth in mineralized

ground quickly diminishes

with fewer ﬁ lters. Audio

discrimination sounds are

not as pronounced with

reduced ﬁ ltering. The more

the electronic ﬁ lters the

better the detection depth

in mineralized ground and

audio discrimination be-

comes more pronounced.

However, more ﬁ lters

equals slower responses

and several targets near

each other become dif-

ﬁ cult to sort out or respond

separately. Settings from 2

- 6 are available.

GROUND FILTERING is adjustable with the

DFX. The ﬁ rst two primary ﬁ lters are contained

within the hardware (electrical parts). The remain-

ing ﬁ lters 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 (ﬁ xed).

Selection of 2 ﬁ lters 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 ﬁ lters will allow for better depth

performance than 2 in slightly higher ground miner-

alization.

Selection of 4 ﬁ lters allows for the traditional high

end Whiteʼs ﬁ ltering ideal for medium to high min-

eralized ground.

Selection of 5 or 6 ﬁ lters allows for new levels of

ﬁ ltering for extreme ground conditions. Although

some models have been described as having 6 ﬁ lters

in the past, two of those six were dedicated to visual

indications alone. The DFX 6 ﬁ lter selection dedi-

cates 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 ﬁ ltration will provide for

performance levels never before available.
