Target Volume
The Target Volume controls the strength of target signals
and at settings above 8 it will slightly increase the volume of
the threshold as well. This is useful for very windy conditions,
people suffering from hearing loss, or when using external
speakers. With the audio amplifier built into the Li-Ion battery
pack you can plug a speaker directly into the battery, and set
an appropriate level of amplification using the Target Volume.
Be aware when switching from headphones to an external
speaker; you may need to make minor adjustments to your
Threshold (p. 33) and Volume Limit (p. 52) controls.
The Target Volume can be used as an Audio boost in quiet
conditions and can also be used to reduce, or smooth out,
ground noise signals in highly mineralised soils. This is a
powerful feature and will work in conjunction with the
Stabilizer control, giving you the ultimate in fine tuning ability.
A bit of experimenting may be required to find the optimum
combination in different conditions.
Note: If you are using the Target Volume to control ground
signals and adjustments to the Rx Gain are required (due to
a change of coil or location), make sure the Target Volume is
returned to the Factory Preset setting first. You can then fine
tune to suit the new conditions.
Tip: A lower Target Volume
is recommended in high
trash areas.
