FISH ID
The Fish ID feature identifies targets that meet certain conditions as fish.
The microcomputer analyses all echoes and eliminates surface clutter,
thermoclines, and other signals that are undesirable. 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 fish symbol on a larger target, etc.
The microcomputer is sophisticated, but it can be fooled. It can't distinguish
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 become
more familiar with the Fish ID feature.
When the unit is turned on for the first
time, the Fish ID feature is automati-
cally turned off. To turn the Fish ID
feature on, press the menu key, then
press the arrow keys until the FISH ID
menu appears. Press the right arrow
key to turn the fish ID feature on. To
turn the Fish ID feature off again, re-
peat the above steps, but press the left
arrow key until "OFF" is highlighted.
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 manual, 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.
