What Do The Colors In The Bottom Light Mean?
Besides depth the bottom light can give you a lot of information. The
width and color content of the bottom signal can tell you what type of
bottom it is.
Ice fisherman can look for movement of color in the bottom signal. If
you see a red line move through the orange or green part of the bottom
signal, it's probably a fish close to the bottom and away from the center
point of the beam angle.
Open water fisherman usually can't see this because the boat moves
too much. You can, however, see changes in the bottom type as you move
along. The wider it appears and the more red in the signal, the harder
the bottom. The narrower it appears and the more green and orange in
the signal the softer the bottom is.
Why Shouldn’t I Use Auto Zoom Mode In My Boat?
You can use the Auto Zoom feature in the open water, but you need to
be aware of what you will see. The Auto Zoom feature is designed to find
the bottom and zoom in on a 6 foot window from there up. As the depth
changes with boat motion, the bottom will change position on the zoom
display. If it gets deeper, the bottom will move off of the screen and no
longer be visible. If the depth gets shallower, the bottom will move up
the display, making your zoom window smaller and smaller. When the
bottom gets to the top of the display or disappears from the bottom of
the display, the FL-18 will reestablish the bottom again. It takes about 5
seconds for the unit to establish a new bottom zoom. If the boat is mov-
ing quickly over large changes in depth, the Auto Zoom feature will not
be able to update the bottom fast enough and the reading will not be con-
sistent.
Why Shouldn’t I Use Bottom Lock Mode For Ice Fishing?
The Bottom Lock feature will not work correctly for ice fishing because
the Bottom Lock feature is constantly looking for depth changes so that
it can keep the bottom locked in place on the zoom display. If a target,
such as fish or your bait, moves into the view with a strong enough sig-
