SONAR FEATURES (cont.)
Fish Symbols
The Fish Symbols feature identi-
fies targets that meet certain con-
ditions as fish. The microcom-
puter analyses all echoes and
eliminates surface clutter, ther-
moclines, and other signals that
are undesirable. In most in-
stances, remaining targets are
fish. The Fish Symbols feature
displays symbols on the screen
in place of the actual fish echoes.
There are several fish symbol sizes. These are used to designate the
relative size between targets. In other words, it displays a small fish sym-
bol when it thinks a target is a small fish, a medium fish symbol on a
larger target, etc.
The microcomputer is sophisticated, but it can be fooled. It can’t distin-
guish between fish and other suspended objects such as trotlines, turtles,
submerged floats, air bubbles, etc. Individual tree limbs extending out-
wards from a group of limbs is the hardest object for the Fish Symbols
feature to distinguish from fish.
You may see Fish Symbols symbols on the screen when actually, there
are no fish. Practice with the unit in both the Fish Symbols mode and
without to become more familiar with the Fish Symbols feature.
The default for Fish Symbols is off. To turn the Fish Symbols feature on,
highlight “Fish Symbols” on the “Sonar Features” menu. Press the ENT
key to turn the Fish Symbols feature on. Any targets the microcomputer
determines are fish will be displayed as fish symbols.
Fish Depths
The Fish Depths feature shows the depth of a fish symbol when it ap-
pears on the display. This lets you accurately gauge the depth of targets.
This feature is available only when the Fish Symbols feature is on.
The default for Fish Depths is off. To turn the this feature on, highlight
“Fish Depths” on the “Sonar Features” menu. Press the ENT key to turn
the Fish Depths feature on. (Note: If Fish Symbols is off, turning Fish
Depths on will also turn Fish Symbols on.)
