NOTE:
Ground mineralization coil size, and ground balance
settings can also infl uence or even reverse the readings. Some
low-conductive metals could make a low tone, and/or some high-
conductive metals could make a high tone. Set to ALL for both high
and low-conductive metals. As long as FINE GEB control is ON,
Variable Audio will be heard.
When prospecting for gold, it is possible to reject a large nugget when se-
lecting to only hear low-conductive metals. The size where a nugget can
be classifi ed as large is not exact as its shape and confi guration can also
be a factor. However, most all small-to-medium sized gold nuggets will
fall in the low-conductive category.
Prospectors should possibly opt
to search while hearing both high and low-conductive metals until a
determination is made as to how targets, including trash, are re-
sponding.
If the gold in the area being searched is predominately small to
medium sized, then searching in low conductivity only will fi nd most gold,
and eliminate most iron trash. Coin hunters can avoid digging small/me-
dium aluminum, foil and small bits of iron trash by using high conductive
only. Relic and beach hunters will ultimately fi nd a way to make use of this
innovative feature. There is much to be learned by extensive fi eld use, but
the possibilities appear to be endless.
MORE about Target Conductivity is listed under VARIABLE AUDIO on
