20. Sweep Speed

(Discrimination section)

Tips -

Typically a competi-

tion or speed hunt would

indisputably be a situation

when an operator would de-

sire the best performance

with a faster loop sweep

speed. Another area well

suited to faster loop sweep

speeds are large areas that

have few metal items near

each other.

Typically high trash areas,

or older areas that deserve

a slower more methodi-

cal search, are ideal for

slower loop sweep speeds.

Settings from 1 - 20 are

available.

The quickness the loop or search coil is passed from

side to side is critical for modern metal detectors

to perform properly regarding detection depth and

discrimination. Sweep Speed is often a personal

preference feature. Individuals may like or dis-

like a particular model based on itʼs required ideal

sweep speed. Additionally an individual may prefer

a quicker sweep speed for a particular area or type

of searching and a slower sweep speed for another

area or type of searching. Most metal detectorʼs

sweep speed is designed into the electrical circuit

and not adjustable.

The SWEEP SPEED of the DFX is adjustable in all

settings except a GROUND FILTER setting of 2.

A GROUND FILTER setting of 2 has a ﬁ xed (not

adjustable) sweep speed.

An adjustment range from 1 to 20 is available. 1 is

the slowest ideal (best performing) loop or search

coil sweep speed, 20 is the quickest ideal (best per-

formance) sweep speed.

SWEEP SPEED regulates the ideal (best perfor-

mance) loop sweep speed by controlling the width

of the target signal the detectors electronic circuit

samples or analyzes. By expanding the sample win-

dow (lower number settings) a slower loop sweep

speed becomes ideal. By narrowing the sample win-

dow (higher number settings) a quicker loop sweep

speed becomes ideal.

RECOVERY SPEED is highly interactive with

SWEEP SPEED and GROUND FILTERING.

Generally faster RECOVERY SPEEDS are better

suited to faster SWEEP SPEEDS. Generally Slower

RECOVERY SPEEDS are better suited to slower

SWEEP SPEEDS. GROUND FILTERING adds

new dimensions to these features. SWEEP SPEED,

RECOVERY SPEED, and GROUND FILTERING

all have a dramatic effect on the way the discrimi-

nation responds to both trash and valued metal

alloys.
