when laying flat in the ground and large pieces of iron, large pieces of lead, lead
mini balls, lead musket balls, lead loom weights, bronze buckles, bronze weights,
bronze artifacts, etc.
NOTE: Mineralization, coil size, and ground balance settings can also
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 Gnd Bal is turned on,
both high and low tones wil be heard.
When prospecting for gold, it is possible to reject a large nugget when
selecting to only hear low-conductive metals. The size where a nugget can
be classified as large is not exact as its shape and configuration 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 responding. If the gold in the area
being searched is predominately small to medium sized, then searching in low
conductivity only will find most gold, and eliminate most iron trash.
Coin hunters can avoid digging pull tabs, foil and small bits of iron trash by using
high conductive only. Relic and beach hunters will ultimately find a way to make
use of this innovative feature. There is much to be learned by extensive field
use, but the possibilities appear to be endless.
MORE about Target Conductivity is listed under VARIABLE AUDIO on page

IMPORTANT -
The Conductivity Toggle only functions when the Ground Balance
Toggle is ON. If the Ground Balance Toggle is in the OFF position,
you must set the Conductivitiy Toggle to either ALL or LOW. If the
toggle is set to HIGH with Ground Balance OFF, there will be NO
SOUND on any target.
