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 color, even at minimum gain. To find depth
in these conditions it is often helpful to read the display
backwards. In the counter-clockwise direction, look for the
bottom by first finding the trailing edge of the signal. Further
into it, you’ll see the main part of the bottom mark and then
the leading edge , as in figure K. If you are in weedy
conditions often, you may want to add an S-Cable to your
system (see page 23). This cuts down your output power
allowing for clearer readings in shallow weedy water.
SEEING FISH
The FL-10 sees a fish as a target, much like the bottom. It
has a leading edge, a width, and color content. Refer again
to figure J. If the range control is set to the 20 foot scale, then
the fish is just over three feet above the bottom. It is a fairly
wide mark and is made up of all three colors. This should be
recognized as a significant fish, something you may want to
catch. The marks that appear just above this fish are smaller
and there is no red. Here is where target identification gets a
bit trickier. Since we do not know the position of the targets
