Volume Limit is the maximum level of sound emitted
by the detector when a target is detected.
If the Volume is set to maximum, all target signals
will be heard and will sound proportional to the
target size and depth. Maximum limit allows you to
hear the difference between a small and large target,
but may be uncomfortable to your hearing if a large
target is found close to the coil.
If the Volume is set to half-way the target signal is
unaffected for a small target, but is limited for a very
large target.
If the Volume is set to minimum, most targets will
potentially be very limited. A low volume will be
more comfortable on your hearing, but will increase
the risk of missing small targets.
Try using a large and small target to adjust the
Volume to a comfortable level.
Threshold should be reset after adjusting the Volume
level.
The detector is able to produce an extremely high
volume if a large or shallow target is located.
