DETAILED OPERATING INSTRUCTIONS
Set the Tone control
• Adjust the Tone control until the threshold is at a comfortable tone
for your hearing. Interpretation of the target signals involves
understanding the difference between the rising and falling tone
and volume of the threshold in response to different targets.
HINT Setting Tone to a high pitch may be more fatiguing, but is more
suitable for identifying the faintest target signals.
Set the Signal control
The human hearing is sensitive to changes in tone, so the operator
is more likely to hear a target signal when both the volume and the tone
change rather than volume alone.
The Signal control gives the operator the ability to choose between a
target signal that has a large variance of tone, or one which has less
variation.
High variance can give the operator more signal definition to interpret,
however in highly mineralised ground this high variance of signal may
cause confusion and a lower setting is preferred.
Soil switch
Use this switch to optimise the detector's ability to detect in different
ground conditions (see page 24 for full description).
Coil switch
Selection of different positions of this switch, changes the electromagnetic
field of the coil thus giving better performance in certain environments
(see page 25 for more information).
Double D has the coil operate in a conventional Double D search
pattern with all the same advantages and disadvantages.
IMPORTANT
You will need to
re-ground balance every time you
select a new position for either the
‘Soil’ or ‘Coil’ switches.
