Side Imaging® Sonar
Your Fishfinder uses Side Imaging®
sonar to provide a wide yet precise
survey of a large area of water,
including

Typically, the Side Imaging® sonar
can search an area that is 240 feet
wide to each side, 480 feet total
coverage, with a depth limitation
of 150 feet. See What’s on
the Side Imaging® Display and
Understanding the Side Imaging®
Display for more information.

Depth capability is affected by such
factors as boat speed, wave action,
bottom hardness, water conditions,
and transducer installation.
