DETECTOR SOUNDS
Threshold and Tone
This is the background sound produced by the detector. The level
is set using the Threshold control. The tone of the threshold is
set using the Tone control.
Target Signal
This is the abrupt change of the tone and volume of the threshold
sound when a target is detected.
• The maximum level is set by the Volume control.
• The amount of tone variation is set by the Signal control.
• If the tone falls first and then rises, as the coil is passed
over a target, this generally indicates a small target.
• If the tone rises first and then falls, as the coil is passed
over a target, this generally indicates a large target.
Ground Noise
These are irregular noises that are difficult, or impossible, to pinpoint
when moving the coil over the ground. Ground noise is caused by
the changing chemistry or 'mineralisation' of the ground. When the
Balance switch is set to Tracking these effects are greatly reduced.
Tune Indication
An initial beep sounds then, while the detector is testing the range of
frequencies for the most stable, the threshold may become more quiet
or chattery. Once selection is complete three sharp 'beeps' are given.
Low Battery Indication
If the battery level drops below the desired power to give full function,
a series of signal pulses are given at 0.5 second intervals.
