You are now ready to start detecting:- Briefly switch back to M\LAB Mode and check your
ground balance then switch back to S\FIX Mode and start scanning at approximately the
recommended scan speed.
Super Fix will now produce a high pitch tone for smaller targets, or a low pitch tone for larger
objects - (see item (10) for further clarification). Super Fix’s modified version of the original
“high/low” or “low/high” target audio signal may be heard at any time by simply switching the
MODE switch from the S/FIX position to the M/LAB position.
If you find that as you are detecting you are now receiving too many confusing false signals
probably caused by ground noise, locate one, then switch Super Fix back to M\LAB Mode and
rescan over the signal. Listen closely - then ask yourself this important question -
Would I
normally dig this Target?
If your answer to the above question is
YES it’s a possible target
- Then Super Fix has found
it for you - switch back to S\FIX Mode and proceed to dig and investigate.
If your answer to the above question is
NO its only ground noise
- First recheck your ground
balance setting on the ground surrounding the noise and then switch back to S\FIX Mode and
rescan, while at the same time gently reducing the SENSITIVITY control to a lower setting
until Super Fix ignores this level signal. You have now set a reference level for Super Fix and
all ground noises up this level will be eliminated. Should stronger ground noises still be a
problem then repeat the above procedure to set a new reference level by further reducing the
SENSIRIVTY Control setting up to the point where you reach what you consider to be a
possible target level.
When searching an area in S\Fix Mode where mains interference is normally evident in
M\LAB Mode, you may find that the SENSITIVITY Control can now be set to higher level to
compensate for any sensitivity lost through Super Fix’s interference rejection circuitry. -
This
is the prime reason for the maximum sensitivity available with this control.
From the above it should be clear that the correct setting of the SENSITIVITY Control is
fundamental to the stable operation of Super Fix and the “GOLDEN RULE” is - if it is noisy
then turn it down.

The CHANNEL selection switch:- Select BOTH to hear both high & low tones, Select HIGH
for high tones only, or LOW for low tones only. When one channel is selected in preference to
the other the excluded channel will then produce a threshold null over a target which may be
ignored if the threshold is turned down to silent search. With the combination of a suitable
searchcoil and the LOW tone selected, much of the ground noise and hot rocks can be
eliminated (along with small gold), and the area can then be searched for the larger and deeper
gold nuggets exclusively.
General information:-
9.
Mono coils of all sizes may be used in both the M\LAB and S\FIX Mode and when scanned at
the recommended search speed a Mono coil will pinpoint targets to the centre of the coil. When
pinpointing over a target in S\FIX Mode the coil should be scanned to fully pass across the
target before the return sweep is commenced. DD coils may provide inconsistent response in
S\FIX Mode, and it is recommended to use them in the M\LAB Mode only.
10.
The audio of a detected target as produced by Super Fix will provide a higher pitch tone for
smaller targets, or a lower pitch tone for larger objects, as to which target tone Super Fix
produces is determined by the original target signature as detected by your Minelab detector,
and if it is composed of “high/low” or “low/high” components. For test purposes an Australian
five cent coin will produce a HIGH tone and an Australian one dollar coin will produce a LOW
tone.
The original “high/low” or “low/high” target audio signal may be heard at any time by simply
