Fish I.D. (Fish Symbols & Depths)
The Fish I.D. feature identifies targets as fish when they meet certain
conditions. The microcomputer analyzes all echoes and eliminates
surface clutter, thermoclines and other undesirable signals. In most
instances, remaining targets are fish. 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 recognizes a target as a small fish, a medium fish
symbol for a larger target and so on.
The sonar's microcomputer is sophisticated, but 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 outward from a group of limbs are the hardest objects 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 also is true.
Does that mean Fish I.D. is broken? No. It is simply 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 many tools we provide so you
can analyze your sonar returns for maximum fish finding information.
This and other features can help you successfully "see" beneath the
boat under varied fishing conditions. Practice with Fish I.D. mode on
and off to become more familiar with it. The default for Fish I.D. is off.
