The Fish I.D. feature displays fish 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, Fish I.D. displays a small
fish symbol when it thinks a target is a small fish, a medium fish sym-
bol on a larger target and so on.
The sonar's 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 ex-
tending outwards from a group of limbs is the hardest object for the
Fish I.D. feature to distinguish from fish.
You may see fish symbols on the screen when actually, there are no
fish. The reverse is also true. The illustrations on the next page show
how Fish I.D. can actually miss fish that are present.
Does that mean Fish I.D. is broken? No — the feature is interpreting
sonar returns in a specific way to help take some of the work out of
reading the screen. Remember: Fish I.D. is one of the many tools we
provide so you can analyze your sonar returns for maximum fish find-
ing information. This and other features can help you successfully "see"
beneath the boat under varied water and fishing conditions. So, prac-
tice with the unit in both the Fish I.D. mode and without to become
more familiar with the feature. The default for Fish I.D. is off.
