About the Display
The FL series flasher display consists of multiple colors (marks) which appear at various
positions on the screen. Understanding what the colors mean, and the position and size of
the colored marks, is the key to being able to interpret the information correctly.
RED = Strong Strength Signals. Strong signals are generally produced by
significant underwater objects, such as the bottom, heavy vegetation, and large fish.
However, smaller objects, such as bait fish, can display as red if the object is directly
under the transducer.
ORANGE = Medium Strength Signals. Medium signals are produced by
smaller objects and softer bottom types. Also, medium strength signals can be produced
by larger objects in the immediate area around, but not directly under, the transducer.
GREEN = Weak Strength Signals. Weak signals are produced by small
objects, such as light vegetation, bait fish, and even air bubbles or aquatic micro marine
life. Larger objects off to the sides of the transducer can also be displayed as green.
The Zero mark always shows, even
if the transducer is unplugged. This
mark indicates the starting point.
Marks just beyond the Zero
mark can indicate algae,
floating vegetation, or even
“ice noise” caused by thick
ice conditions.
Bottom is generally the
most prominent mark
on the display. Bottom
usually starts with a
wide band of red,
with orange and green
trailing.
READ DEPTH HERE : The current depth
is indicated by the leading edge of
the bottom mark. The depth is 12
feet here.
You read the
display in the clock-
wise direction. The
further around you
go, the deeper the
water.
Fish, bait fish, and
even your lure, will
show anywhere
between the Zero
mark and the Bottom
mark. Here, a weak
object shows about
a foot above a much
stronger object.
Marks beyond the bottom
mark can indicate either
hard objects within a soft
bottom or large objects
well off to the side.
What is What ?
Here are the basics of what you will see on
the display of an FL series flasher.
NOTE: The FLX-28 has a more sophisticated color scheme. See page 24 for details.
