Volume Limit

Range: 0–30
Factory Preset: 30
The Volume Limit sets the maximum volume
of target signals. When detecting, the sound
produced by a distant target will be quiet.
As the coil gets closer to the target, the
volume increases until it reaches the Volume
Limit setting.
A high Volume Limit will allow a greater
difference between a small and large target.

The Factory Preset for Volume Limit is set

headphones, use the Volume Limit setting to
reduce the audio volume.

CAUTION: A high Volume Limit setting
might damage your hearing if a large
target is detected.

Volume Gain

Range: 1–30
Factory Preset: 24
The Volume Gain controls the amplification
of a target's audio response, relative to the
target signal strength. The Volume Gain
control is the Audio setting that is most
similar to volume adjustments in other
devices (e.g. radio or television
volume controls).
With a setting of 1 the target signal will not
be amplified. Weak target signals will sound
quiet, medium target signals will sound mid-
range and strong target signals will sound
loud. There will be greater differentiation
between target signal strengths, however,
weak signals will be harder to hear.

With a setting of 15, the audio response
will be partially amplified. Weak to medium
strength signals will sound louder, but strong
signals will not sound much louder than
medium signals as the volume reaches the
Volume Limit.

With a setting of 30, all target signals will
be amplified to a loud audio response. At
this setting there will be less differentiation
between medium and strong signals, but
weak target signals will be easier to hear.
