FASTRACK
The FasTrack feature converts
all echoes to short horizontal
lines on the right side of the
display. The graph continues
to operate normally. FasTrack
looks similar to a flasher, mak-
ing it useful for fishing at an-
chor. Since the unit isn’t mov-
ing, fish signals are long lines
on a normal chart display.
FasTrack converts the graph
to a vertical bar graph that, with practice, makes a useful fishing accessory.
To turn FasTrack on, press the MENU key, then press the key next to the
“Sonar Controls” label. Now press the key adjacent to the “More” label until
the “FasTrack” menu appears. Press the key next to that label. Finally,
press the CLR key to erase the menus. To turn FasTrack off, repeat the
above steps.
GRAYLINE
®
An easy way to determine the relative strength of echoes is by using the
Grayline feature. This feature “paints” gray on targets that are stronger
than a preset value. This lets you see the difference between a hard and
soft bottom. For example, a soft or muddy bottom returns a weaker signal
which is show with a narrow or no gray line. A hard bottom returns a strong
signal which causes a wide gray line.
Grayline also helps determine the strength of target echoes. If you have
two targets of equal size, one with gray and the other without, then the
target with gray is the stronger signal. This helps distinguish weeds from
trees on the bottom, or fish from structure.
Grayline is adjustable. Since it
shows the difference between
strong and weak signals, ad-
justing the sensitivity may also
require a change in the Grayline
level. The level chosen by the
GlobalMap 2000 is usually ad-
equate for most conditions.
Experiment with your unit to
find the Grayline setting that’s
best for you.
