Troubleshooting Guide
Problem
Reason
Suggestion
The detector
displays or
sounds
without
detecting any
target
1. The detector may
receive interference
and false signal from
broadcast antenna and
other electronic lines
2. The humidity of
environment may be
extremely high
1. Change searching place
2. Wait for some time to
check again
The detector
sounds false
signals.
1. Sensitivity set too high/
environmental
electromagnetic
interference
2. Sweeping the detector’s
search coil too fast or at
wrong angle
3. Using 2 detectors in
close proximity
1. Reduce sensitivity
2. Sweep the search coil
more slowly and hold
the detector correctly
3. Keep two detectors at
least 6 meters(20’) apart
The detector
does not
detect
anything
1. Sensitivity set too low
2. Target range is
eliminated
3. Search coil is not
parallel to the ground
1. Increase sensitivity
2. Recover all target range
3. Adjust the search coil
angel to be parallel to
the ground
LCD display
multiple target
categories or
emits several
sounds at once
1. There may be over one
kind of metal targets
2. The detector can’t
identify the target.
Sometimes, oxidized
metal also causes the
excursion of target
arrow and tone.
1. Reduce the sensitivity to
eliminate the detection
of the deeper target
2. Sweep the search coil
with different angles
The detector
does not
function.
1. Five-pin cable not
connected well
2. Dead battery
1. Re-plug it properly
2. Replace batteries
