About the Display
The FL series flasher display consists of three 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.
