Tips - Typically a competi-
tion or speed hunt would
indisputably be a situation
when an operator would
desire the best perfor-
mance 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 methodical
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 dislike a
particular model based on it’s 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 detector’s
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 fixed (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
performance) 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
window (lower number settings) a slower loop
sweep speed becomes ideal. By narrowing the
sample window (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.
