IMPORTANT:
SENSITIVITY, THRESHOLD, iSAT, iMASK are critical settings and must be
adjusted properly to ensure noise-free optimal detector performance. Factory default
positions for each of these settings are marked on Control Panel and offer the User a
baseline starting point for detector use in the field. These settings should be adjusted
according to local ground and environmental conditions in order to maximize detection
performance.
SENSITIVITY, THRESHOLD, iSAT, iMASK
In ALL METAL mode, THRESHOLD (continuous background humming sound) should be
adjusted to be ‘minimally audible’. Improperly adjusted THRESHOLD can mask the signal
of smaller and deeper targets (due to their low audible response) as they are lost in the
THRESHOLD hum.
IMPORTANT:
GROUND BALANCE the
Au GOLD FINDER
prior to detecting in ALL METAL
mode. Failure to properly GROUND BALANCE the detector when using ALL METAL mode
will result in falsing and/or disruption in THRESHOLD stability as the detector responds to
ground mineralization which would otherwise be cancelled out with proper GROUND
BALANCE.
iSAT adjusts the speed that the detector recovers its THRESHOLD hum and negates the
effects of mineralized soils.
IMPORTANT:
iSAT adjustments should be carefully applied to attain detector stability as
any increase in iSAT results in loss of detection depth.
RECOMMENDATION:
Should highly mineralized conditions cause detector falsing and/or
disruption in THRESHOLD hum, lower the SENSITIVITY to regain detector stability. This
should be accomplished prior to increasing iSAT. Should you be unable to regain stability
by reducing SENSITIVITY below default seven '7', reset SENSITIVITY to default position
prior to increasing iSAT.
In low mineralization conditions, decrease iSAT and slow coil sweep speed to enhance
detector detection depth.
In ALL METAL mode, SENSITIVITY behaves similar to THRESHOLD with one important
difference, having too much SENSITIVITY can result in falsing and/or popping sounds.
-Detector is calibrated to be very sensitive to small gold targets;
-Ground mineralization may cause detector overload;
-Adjust SENSITIVITY to a point where detector is unstable and reduce slightly to
optimize SENSITIVITY setting without negatively impacting detection
performance (ex. Detector stability is the same at SENSITIVITY '5 - 8' and unstable
at '9', reduce to '8' and proceed to detect);
Factory default SENSITIVITY setting is ‘7’ and will provide User an effective SENSITIVITY
setting for most mineralization/environmental conditions.
SENSITIVITY, THRESHOLD, iSAT - ALL METAL Mode
Automatic GROUND BALANCE may fail to sequence in the following conditions:
- Metal under search coil when attempting Automatic GROUND BALANCE;
- Ground is too conductive;
- Ground mineralization is too low.
Should Automatic GROUND BALANCE sequence fail to complete, please do the following:
- Change GROUND BALANCE location, repeat Automatic GROUND BALANCE sequence;
- Change to Manual GROUND BALANCE if changing location does not allow Automatic
GROUND BALANCE sequence to successfully complete;
Should Automatic and Manual GROUND BALANCE attempts fail, continue detecting
without GROUND BALANCE as follows:
- Restart
Au GOLD FINDER
;
- Sweep search coil over ground listening carefully for changes in tone as you
sweep;
- If you hear a sound as you sweep coil over the ground, switch
Au GOLD FINDER
to either DISC.1 FAST or DISC.2 DEEP;
- Adjust DISC.FILTER gradually while sweeping coil to eliminate any sound;
- Once sound has been eliminated, proceed to use
Au GOLD FINDER
.
- GROUND BALANCE will remain stable and does not require adjustment once successfully
attained (Automatic or Manual).
NOTE:
DISC FILTER is not active when ALL METAL mode is selected;
