Au GOLD FINDER
detector has an extremely fast recovery speed which is necessary for
detecting in highly mineralized grounds, areas with hot rocks and/or trashy areas.
To maximize the advantages of the fast recovery speed of the
Au GOLD FINDER
, you
should make wide, sweeping passes of coil over the ground being searched instead and
minimize narrow, quick side-to-side sweeps.
Sweep speed of the
Au GOLD FINDER
is extremely important for accurate target
identification and response. It is recommended that a single sweep (left to right) take
between 1 and 1.5 seconds with a complete left-right-left sweep lasting not less than 2
seconds.
Ensure coil is maintained level over the ground throughout entire sweep keep coil
approximately 2” over the ground avoiding contact with rocks and ground.
Sweep Speed and Target Identification
The
Au GOLD FINDER
is exceptionally sensitive to very small, fine gold targets.
IMPORTANT:
Large targets and targets near ground surface can result in audible overload.
This overload tone resembles a continuous siren sound. When you hear this tone, simply
raise the coil and continue sweeping the area. This will allow the
Au GOLD FINDER
to
recover from overload, process target and provide proper response.
Large or Near-Surface Targets
Falsing is the detector response to undesirable effects such as high ground mineralization,
hot rocks and electromagnetic interference including use of detector in close proximity to
other metal detectors.
Most falsing can be controlled by simply reducing SENSITIVITY and/or THRESHOLD values
until falsing in minimized or eliminated. Please read and become familiar with information
provided in this manual for adjustment of GROUND BALANCE, SENSITIVITY, THRESHOLD,
iSAT and iMASK.
Another type of falsing is the detection of an apparent desirable target with no target
located. This type of falsing is very common when detectors are used in areas containing
rusting or corroding iron, nails, etc. in the soil. The corrosion of ferrous metals (oxidation)
creates a ‘halo’ of oxides around an undesirable target (i.e. nail) resulting in false or falsing
response. The object may have totally decomposed into an oxidized state and when
attempting to dig the target, nothing is found. You do not want to eliminate this type of
falsing as you may be masking small, fine desirable targets.
Detector Falsing
Hot Rocks: It is important to understand that mineralized stones, rocks, cavities in the
ground being searched and/or mineralization of the ground itself can significantly
influence
Au GOLD FINDER
target response.
