Side Imaging® Sonar - Humminbird 598ci Operation Manual

Side Imaging® Sonar
86° 86°
Your 598ci HD SI Fishfinder uses
455kHz 455kHz
Side Imaging® sonar to provide a
wide yet precise survey of a large
20°
area of water, including detailed
200kHz
bottom topography and fish-
60°
83kHz
attracting structure orientation. The
180 Degree Total Coverage
Side Imaging® transducer returns
are processed into an image similar
to an aerial photograph.
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.
The Side Imaging® transducer also
provides down imaging displays on
the screen. See What's on the
Down Imaging™ Display for more
information.
Depth capability is affected by such
factors as boat speed, wave action,
bottom hardness, water conditions,
and transducer installation.
