Kellyco GOLD FINDER User Manual - page 19
-If detector is stable but too noisy (loud), THRESHOLD should be decreased;
-If detector is unstable (falsing and/or popping), SENSITIVITY should be decreased;
-If detector is unstable (falsing and/or popping) after reducing SENSITIVITY, reset
SENSITIVITY to its default position and make minimal increase adjustment to iSAT until
detector stability is attained.
In DISCRIMINATION modes, THRESHOLD is not functional. SENSITIVITY is used to fine tune
detector stability for changes in ground mineralization and directly affects detection
depth and noise free detector operation.
SENSITIVITY fine tuning
(DISCRINATION modes):
- Set SENSITIVITY to default setting ‘7’;
- Set DISC FILTER to default setting ‘10’;
- Complete GROUND BALANCE procedure;
- Sweep search coil level above ground with no metal present at 3 - 6 cm (1''- 2”)
as if detecting;
- Reduce SENSITIVITY gradually to eliminate any falsing and/or popping while
sweeping search coil.
iMASK eliminates the effects (falsing and/or popping) which are present when detecting
over hot rocks and/or highly mineralized ground while using DISCRIMINATION modes.
The calibrated range of iMASK is ‘1 - 6’ ('1' iMASK Off - '6' iMASK Max). There is no change in
iMASK settings '6 - 10'.
Sensitivity in Discrimination Modes
iMASK is used to eliminate or minimize false signals resulting from detecting highly
mineralized soils or hot rocks when using DISCRIMATION modes.
iMASK has a functioning range between ‘1’ and ‘6’. Selection of iMASK levels above ‘6’ (i.e.
‘7’ - ‘10’) are factory calibrated at level ‘6’ and will not further improve masking.
iMASK default setting is level ‘6’ as indicated on Control Panel. This provides maximum
masking of ground interference often experienced in highly mineralized soils. Selection of
level ‘6’ will provide User with the ability to significantly minimize or eliminate detector
falsing (false signals) which often occurs when detecting over highly mineralized ground.
IMPORTANT:
Default iMASK setting of ‘6’ will result in the inability for the
Au GOLD
FINDER
to detect and respond to very conductive metals such as copper.
RECOMMENDATION:
Au GOLD FINDER
is extremely sensitive to conductive metals such
as copper, micro-jewelry and coins. When using the
Au GOLD FINDER
to detect for
mineralized copper, micro-jewelry, coins and other highly conductive metals, it is
recommended that you set iMASK to ‘1’.
