Kellyco GOLD FINDER User Manual - page 13
NOTE:
Decreasing SENSITIVITY will often resolve coil overloading due to highly
mineralized ground.
RECOMMENDATION:
Review Sensitivity, Threshold, iSAT and iMASK sections on pages
15-16.
THRESHOLD dial is used to adjust the background hum sound commonly referred to as
the threshold sound. THRESHOLD tone is continuously heard when
Au GOLD FINDER
is
operating in the ALL METAL mode.
THRESHOLD Dial
iSAT / iMASK dial is a multifunction switch controlling iSAT settings when ALL METAL
mode is selected, and alternately controlling iMASK settings when DISC.1 FAST or DISC.2
DEEP are selected. Default position for both iSAT and iMASK are calibrated at six '6' and are
clearly marked on the Control Panel. Default setting of six '6' should be used and only
adjusted as described on pages 15-16 of this manual.
iSAT / iMASK Dial
The TONE / LED toggle switch provides the User the ability to choose between
audio/visual (single tone/LED) response and audio (multi-tone) response as follows:
-1 TONE LED ON provides User with single tone target response and simultaneous LED
display of FERROUS (Red LED) or GOLD NON-FERROUS (Green LED) target identification;
TONE / LED Toggle Switch
Optimal performance using ALL METAL mode requires a stable THRESHOLD.
Changes in ground mineralization and soil structure may cause a rise or fall in the
background hum. A disruption of THRESHOLD stability may result in loss of target
response to certain metals such as small gold nuggets. You should only adjust iSAT
to maintain the steadiness of the THRESHOLD tone. Adjustment directly affects the
detector recovery speed and THRESHOLD stability.
iSAT consists of ten levels. The default level is six '6' and is clearly marked on the
Control Panel. It is recommended that iSAT be increased when detector is used in
high mineralization and decreased in low mineralization. For more details, please
read SENSITIVITY, THRESHOLD, iSAT and iMASK section on pages 15-16.
iSAT
iMASK is used to eliminate falsing (false signals) caused by ground mineralization or
hot rocks when searching in discrimination modes. Default iMASK setting is six '6'. At
level one '1', iMASK is turned off.
For more details, please read SENSITIVITY, THRESHOLD, iSAT and iMASK section on
pages 15-16.
iMASK
DISC FILTER is used to eliminate undesirable targets when DISC1. FAST and DISC2. DEEP
modes are selected. The default setting for DISC FILTER is ten ‘10’ and is clearly marked on
the Control Panel. Adjust DISC FILTER as needed to eliminate unwanted target responses
(nails, coins, etc.).
NOTE:
DISC.FILTER is functional in the DISC.1 and DISC.2 modes only. DISC FILTER is
non-functional when ALL METAL mode is selected.
DISC FILTER enables elimination of response to undesirable targets. DISC FILTER provides
User with the ability to reject mineralized rocks (hot rocks) and undesirable targets such as
iron and foil which often interfere with detector response.
DISC FILTER ranges between 0-40. The factory default value (optimal starting point) is ten
'10' which is clearly marked on Control Panel.
To use DISC.FILTER, first GROUND BALANCE the Au GOLD FINDER. Select one of the
Discrimination modes (DISC.1 FAST, DISC.2 DEEP). Next, set the DISC FILTER to '0', then
sweep the coil over the undesirable target while simultaneously and slowly turning the
DISC FILTER knob clockwise until no response is heard.
