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, for 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 that when switching from headphones to an external speaker, you may need to make minor adjustments to your Threshold and Volume Limit 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: Whenever adjustments to the Gain are required, due to a change of coil or location, make sure the Target Volume is returned to the FP setting first. You can then fine tune to suit the new conditions.
