HELPFUL TIPS
WHERE TO SET THE GAIN CONTROL
Set the gain control so as to get a strong bottom mark. If
you don’t see a bottom mark, switch to a deeper range
setting, then turn the gain up until the bottom appears. Good
bottom marks will show all three colors. The leading edge of
the bottom echo should show a solid red band bleeding into
orange. The trailing edge of the bottom mark will bleed from
orange into green. Keep the gain control as low as possible,
especially in weedy conditions, while still showing a good
bottom signal.
HOW TO RECOGNIZE FISH
Any mark that is between the zero and the bottom marks,
but not connected to either, COULD be a fish. Remember that
the colors indicate the strength of the mark. If you see a red
mark, it probably is a fish. The wider the red part of the mark
is, the larger the fish is. An orange or green mark could also
be fish, but we do not know for sure. They may indicate small
bait fish or larger fish off to side of your position. Only if these
marks turn to red can you be fairly sure it is a fish.
AVOIDING TROLLING MOTOR NOISE
Usually a simple grounding wire connected between the
negative trolling motor lead and the negative starting
battery post will eliminate any noise. Use an 18 gauge wire
with a 1 amp fuse. Contact Vexilar service or log on to
