Garrett Metal Detectors Infinium LS - Manual (Page 26)

Increase the Discrimination setting only as needed
in order to reduce saltwater detection. Typically, a
setting of three or less is sufficient. Do not be con-
cerned about missing targets due to the increased
Discrimination. Rather, the stable operation achieved
with this slight increase in Discrimination will ensure
the best possible target detection for this saltwater
environment.
Land searches
When searching near wire fences, metal buildings,
etc., make sure that you scan the searchcoil paral-
lel to the structure. This will minimize the interfering
responses caused by the metal structure.
Prospecting
Gold and other precious metals can be found in
various forms with the Infinium LS. You will most likely
be searching for nuggets, but gold can also be found
as lode or hard rock deposits in a vein, usually mixed
with other minerals. The Infinium LS can also be used
to locate placer deposits in streams or dry sand.
Since working vein or lode gold can require
expensive tools or technology and placer deposits
must be panned for recovery, these forms are some-
times unsatisfactory for metal detector hobbyists.
Recovering a nugget, however, is as simple as putting
it in a treasure pouch.
