your settings (see page 37). The middle of the page contains a right-

the screen are closer to you than those on the left.
Along the right side of the screen is a scale that reects the depth of
the area shown.
The most intense solid colors indicate the strongest sonar returns
(red is the default). The weakest sonar returns appear in the least
intense color (blue is the default).
