TYPICAL INDICATIONS
The three-color display on the FL-8SLT can give you a lot of infor-
mation if you know how to read it. A color represents the strength of a
signal. A red color indicates a strong signal, an orange color indicated a
medium strength signal, and green represents a weak signal. The colors
will combine to indicate objects, such as bottom echoes, structure, fish,
and plankton. The way in which they combine, and the speed in which
they do so, tells you what is what.
The following examples illustrate some of the different conditions
that you may encounter and what the display on the FL-8SLT may look
like.
HARD BOTTOM
Under these conditions the bottom will be almost all red, although
you will always see some orange and green at the trailing edge, as in fig-
ure J. A sharp red leading edge tells you that the bottom is very clean. If
you were to move from a hard bottom to a softer -bottom you would see
a change in color to more orange and green. Try not to change the Gain
setting as you move around.
WEEDY BOTTOM
In weedy conditions the bottom can be harder to determine. Figure
K gives you an idea of what it may look like. To find the bottom in weeds
it is important to keep the gain control low. If the gain is too high the
bottom and the weeds will "run together" making it difficult to determine
the actual depth. Some weed beds can be so dense that they will display
as solid red, even at medium gain. If you fish in these conditions often
you may want to add an S-Cable to your system (see page 27).
