The Fish Alarm alerts you to the presence of fish, or other targets not attached to the bottom, in
the water beneath your boat. The Fish Alarm has 3 different settings which correspond to the 3
different size fish targets shown on-screen.
To enable Fish Alarm, use the UP and DOWN arrow buttons to adjust the size return you want to
be alerted to: large fish only, large and medium size fish, or all fish. Then press ENTER to enable
the alarm.
Remember that it is impossible for Fish Alarm sonar to determine if a signal return is a fish or
some other type of object or suspended debris. Any object not connected to the bottom is
normally a fish and is portrayed as a fish symbol. The strength of the reflected sonar signal from a
target is a good indicator of the size of the target, and the fish symbol displayed represents the
strength of the signal reflected from it.
ID is the automatic identification of target returns based on the strength of the returned signal and
other factors. Three options are available: ID "On" displays targets as one of three different size
fish symbols.
The fish symbols may be hollow, indicating that the target is detected in the wide beam only, or
solid, indicating that the target is detected in the narrow beam, and is located directly under the
boat.
