volume
Volume is the level of sound emitted by the 
detector when a target is detected. The Volume 
control limits the maximum volume of  
target signals. 
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 pitch depending on the signal strength 
(from a target or ground mineralisation). This 
volume range is proportional to the maximum 
volume setting. 
Speaker/Headphone Volume
The X-Terra 705 is able to save separate 
settings for both the speaker volume and 
headphones volume, switching from one to 
the other automatically as the headphones are 
connected (Accessories, p. 52).
Set the speaker volume without headphones 
connected. Set the headphones volume with 
the headphones connected. Use the simple 
detecting exercise (p. 16) with dierent targets 
to conrm both the speaker and headphones 
volume settings.
  Press Menu/Select 
 and choose  
Volume 
.
  Use the + and – buttons to adjust the 
Volume limit.
  Press Pinpoint/Detect 
 to return to 
detection.
When the detector battery is low (indicated 
by the low battery icon) the speaker volume 
limit will be automatically 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 sooner.

Threshold
When Volume and Threshold settings are used 
together, there is greater control over target 
audio response.
Threshold
When using headphones, it is 
recommended that the volume be set 
so that a loud target signal will not 
damage your hearing.
