Vexilar LC-8 - Manual (Page 13)

Unlike open water use, the direction in which the transducer is
pointed is very critical. You want your bait to be located in the dead
center of the cone sound, directly under the transducer. This way you
can see very small baits at low gain settings and also see fish come in
from all sides. If you are not using the Ice-Ducer system, the trans-
ducer must be attached to an adjustable arm so that it can be manual-
ly pointed directly at the bait. Sometimes it helps to attach a bubble
level to the transducer so that you know when it's straight.
After your system is properly set up, adjust the gain until you see
your bait. You may need to readjust the gain control to keep the bait
in view. This is due to the changing condition and position of your
bait. If you are using a swimming bait or a lure that darts to the side
as it's jigged, you will see the signal change as the bait moves.
Sometimes it may even disappear if the bait goes out of the cone of
sound.
