Side Imaging® Sonar
Your 700 Series™ Fishing System
uses Side Imaging® sonar to provide
a wide yet precise survey of a large
area of water, including detailed
bottom topography and fish-
attracting structure orientation. The
Side Imaging® transducer returns are
processed into an image similar to an
aerial photograph. Typically, the Side
Imaging® sonar searches an area
that is 240 feet wide to each side,
480 feet total side coverage, with a
depth limitation of 150 feet. See
What’s on 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.
