FISH l.D.
The Fish l.D. feature identifies
targets
that meet
certain conditions as fish.
The
micro-computer analyses
all echoes and eliminates
surface
clutter,
thermoclines,
and other
signals
that
are undesirable. In most
instances,
remaining targets
are fish. The Fish l.D. feature
displays symbols
on the
screen in
place
of the actual fish echoes. There
are fourfish
symbol
sizes:
tiny,
small, medium,
and
large.
These are used to
designate
the relative
size between
targets.
In other
words,
it
displays
a small fish
symbol
when
it thinks a
target
is a small
fish,
a medium fish
symbol
on a
larger target,
etc.

suspended objects
such as

etc. Individual

wards from a
group

object
for the Fish 1.0. feature
to

from fish.

symbols
on the screen when
actually,
there are no
fish. Practice with the unit in both the Fish

pears
and the sonar screen returns. Echoes will continue

the
screen, however,
the surface clutter at
the
top
will no
longer
be
displayed. Any
targets

as fish
symbols.
Remember,
the Fish l.D. feature can't be used when
the Ultra III is in the
