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 distin-
guish between fish and other suspended objects such as turtles, sub-
merged floats, air bubbles, etc. Individual
tree limbs extending outwards from a group of
limbs are the hardest objects for the Fish ID
feature to distinguish from fish. You may see
Fish ID symbols on the screen when, in fact,
there are no fish. Practice with the unit when
the Fish ID feature is on and off to become
more familiar with Fish ID. To turn this feature
on, press the menu key until the Fish ID
feature’s menu appears as shown at right.
Now press the up arrow key. This turns the
feature on. To turn it off, repeat the above
steps, but press the down arrow key instead.
The Fish ID feature can’t be used when the X-45 is in the manual mode.
If you turn the automatic feature off, the Fish ID feature will automatically
be turned off, also.
