VOLUME
Volume is the level of sound the detector gives 
when a target is detected. The volume control 
limits the potential loudness of target signals. 
The X-TERRA has proportional target signal 
volume. The sound produced by a distant 
target starts softly. As you get closer, the 
volume level increases rapidly until it reaches 
the maximum level that has been set.
The sound produced by the detector in 
pinpoint or ground balance will vary in volume 
and tone depending on the signal strength 
(from a target or ground mineralisation). This 
volume range is proportional to the maximum 
volume setting. 
The X-TERRA is able to save separate settings 
for both the speaker volume and headphone 
volume, switching from one to the other 
as soon as the headphones are connected 
(Accessories, p. 72).
Set the speaker volume without headphones 
connected. Set the headphone volume with 
the headphones connected. Use the exercise 
(p. 22) with different targets to confirm both 
the speaker and headphone volume settings.
When the detector battery is low (indicated by 
the low battery icon) the speaker volume limit 
will be reduced. This saves battery power and 
extends detecting time. 
You may choose to override this and increase 
the volume limit, but you then risk the 
detector shutting down earlier.
