Fisher
has designed this metal detector with a 13 kHz which will
make it a
great metal detector for coin, Jewelry, relic and even gold
prospecting.
The Fisher F70 metal detector has advanced software based motion
discrimination with notch for searching trashy areas.
The double-filter discrimination mode of the Fisher F70, makes this
metal detector worth its weight in gold.
It
distinguishes between unwanted metal objects, like aluminum and
nails,
from the more desirable metals. Plus, a two-digit setting
number
displayed on the LCD monitor of the Fisher F70, indicates
the type of
ground mineralization from wet salt to magnetite and
other black iron
minerals.
