Setting the Volume
of Target Signals
The Volume control is used to adjust target signal
volume.
As you turn this control clockwise, the volume of target
signals will increase.
At the most clockwise position, the volume is set at the
maximum / loudest, position.
If the Volume is set to maximum, all target signals will
be heard and will sound proportional to the target
size and depth. Maximum 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.
A low volume will be more comfortable on your hearing,
but you may risk missing small targets.
Try using a large and small target to adjust the Volume to
a comfortable level.
The detector is able to produce an
extremely high volume if a large or
shallow target is located.
Protect your ears!
Sensitivity
Sensitivity is the detector's level of response to its
environment and to targets. The Sensitivity control
allows you to adjust the level of sensitivity to suit the
ground conditions in which you are detecting.
Auto
At the most anti-clockwise position this control 'clicks'
into the Auto position. In this setting the Excalibur II will
automatically select its optimum level of sensitivity to
suit the detecting conditions.
Auto is a suitable sensitivity setting when detecting on
wet sand, on concentrated black sand, or in the water.
Manual
Turning the control clockwise will 'click' the Excalibur
II out of the Auto setting into Manual. As you continue
to turn this control in a clockwise direction the level of
sensitivity will reduce. At the most clockwise position (1)
the Excalibur II is at 'minimum' sensitivity.
Adjusting the sensitivity manually is suitable when
detecting on the beach and on very quiet/stable
(unmineralised) ground, where the ground conditions do
not change often.
The detector with a high Sensitivity setting will
detect deep targets but may respond to unwanted
noise and ground signals. A high Sensitivity setting
is recommended for stable conditions with low
interference.
The detector with a low Sensitivity setting will ignore
unwanted noise and ground signals, but may miss deep
targets. A lower Sensitivity setting is preferable for very
variable, 'noisy' conditions or high trash areas.
