FASTRAK
This feature converts all echoes to
short horizontal lines
on
the
display's
far
right
side.
The
graph
continues to
operate
normally.
FASTRAK
gives
you
a
rapid update
of conditions di-
rectly
under the boat. This makes it
useful for ice
fishing,
or when
you're
fishing
at anchor. Since the unit is not
moving,
fish
signals
are
long,
drawn
out lines on a normal chart
display.
FASTRAK converts the
graph
to a
vertical bar
graph
that,
with
practice,
makes a useful addition to
fishing
at a
stationary
location.
To turn FASTRAK
on, press
the menu
key twice,
then
press
the
key adjacent
tothe'TLJRN FASTRAKON" label. To
turn it
off, repeat
the same
steps.
The
'TURN FASTRAK OFF' label
appears
instead of the "TURN FASTRAK ON"
label.
