FISH ID
The Fish ID feature identifies targets that meet
certain conditions as fish. The microcomputer
analyses all echoes and eliminates surface clut-
ter, thermoclines, and other signals that are un-
desirable. In most instances, remaining targets
are fish. The Fish ID feature displays symbols
on the screen in place of the actual fish echoes.
There are four fish symbol sizes: tiny, small,
medium, and large. These are used to designate
the relative size between targets. In other words, it displays a small fish
symbol when it thinks a target is a small fish, a medium 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 ID feature to
distinguish from fish.
You may see Fish ID symbols on the screen when actually, there are no
fish. Practice with the unit in both the Fish ID mode and without to be-
come more familiar with the Fish ID feature.
To turn the Fish ID feature off, press the MENU
key, then select “SONAR SETUP”. Now choose
“FISH ID” from this menu. Press the left arrow
key to turn the fish ID feature off. To turn the Fish
ID feature on again, repeat the above steps, but
press the right arrow key until the “ON” is high-
lighted. Any targets the microcomputer deter-
mines are fish will be displayed as fish symbols.
Remember, the Fish ID feature can’t be used when the unit is in the manual
mode. If you turn the Fish ID feature on when the unit is in the manual
mode, the microcomputer will turn the automatic feature on. If you turn
automatic off when the Fish ID feature is on, the Fish ID feature will be
turned off also.
FISHTRACK™
The FishTrack feature shows the depth of a fish symbol when it appears
on the display. This lets you accurately gauge the depth of targets. This
feature is available only when the Fish ID feature is on.
