Occasionally you will be preoccupied with other tasks and unable to
concentrate on watching the sonar picture. In such cases it would be
a good choice to use the audio function. This function enables you to
monitor echoes from fish schools and seabed through the built-in
speaker.
After you become accustomed to utilizing the audio function, you
should be able to detect a fish school from a range longer than you
can detect it on the screen.
