FALSE SIGNALS
nugget country and with practice you'll be able to
recognize a lot of it. Nails for example will respond
with two beeps across the length of the nail (end
to end), but only one beep when the search coil is
swept at right angles to the length of the nail. Also,
most trash is shallow and comes in bigger sizes than
nuggets. Hence it will sound different especially in
the Auto Tune Mode. Trash will sound off over a
larger area of the coil, the tone will be louder and
the pitch will increase more, starting out at a low
beep, increasing to aloud squeal.
5. ELECTRICAL INTERFERENCE: Caused by radio/TV
stations, power lines and other detectors operating
at the same frequency. SOLUTIONS: Move farther
away from the source. Lower sensitivity. Reduce
sweep speed. Use Auto-Tune mode. Wrap the
search coil cable tightly around the stem. In some
buildings electrical interference may be so
noticeable that you'll have to lower the sensitivity
or go outside just to bench test your Gold Bug.
6. DIGGING TOOL: If you're carrying a digging tool
in one hand, your Gold Bug may sound off each
time you swing the coil beneath it. SOLUTION: Hold
it behind your back or up above your waist.
