the response to good conductors such as
coins and fine jewelry. In Standard mode,
the response to poor conductors can be
eliminated effectively; however, if these
objects are too close to the searchcoil,
a detection response may occur. The
response to good conductors, although
somewhat diminished, remains relatively
strong. Some jewelry such as rings and
thin gold necklaces are found in the
middle of the conductivity range, so it's
important to dial in only the amount of
elimination needed for the search area.
Standard mode permits a very slow
searchcoil sweep, making it particularly
effective for pinpointing targets. It provides
the deepest possible detection and is
most useful in areas with little trash.
Discrete Trash Elimination is a search
mode exclusive to the Sea Hunter Mark
II. It is similar in operation to detectors
with a Motion Discrimination mode in that
it provides more precise and enhanced
