The ambient humidity is too
high.
Sensitivity is too
high/environmental
electromagnetic interference
Too fast or detector probe at
wrong angle.
Using 2 detectors in close
proximity to each other
Sensitivity set too low
Probe is not aligned parallel
to the ground
The detector has found
several different metal
objects.
The detector cannot identify
the target. Sometimes,
oxidized metal also causes a
Action
