The microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as turtles, submerged 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 a 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- 28 is in the manual mode. If you turn the automatic feature off, the Fish ID feature will automatically be turned off, also.
