Audio Tone
Adjusting the pitch of the Threshold.
Audio Tone is the pitch of the Threshold emitted by
the detector.
Large, deep targets produce a different response to small,
shallow targets. It is important to adjust the Audio Tone to suit
the type of target you are searching for.
A high Audio Tone setting may help identify small targets from
ground signals, but a low Audio Tone setting may allow deep
target signals to stand out.
Everyone’s hearing is different and you may find that you hear
targets better in a particular range of Audio Tone. Try using
a large and small target, and adjust the Audio Tone until you
find a setting that produces the most obvious signal response
for your hearing.
