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
figure 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 bot-
tom 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 dif-
ficult 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 sys-
tem (see page 28).
