2.12 Detecting Fish Schools Aurally
Sometimes you may 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’ve become accustomed to monitoring fish aurally, you should be able
to detect a fish school from a range longer than you can detect it on the screen.
In addition you may judge whether the fish school is approaching or going away;
the tone becomes higher when the school is approaching and lowers when the
school is going away.
