Side Imaging Technology: How It Works
(1197c SI Combo models only)
Side Imaging sonar uses two very precise sonar beams that are directed to either side of the boat and
“illuminate” the bottom contour, structure, and fish, and display results in a “picture-like” image.
• Side beams are extremely narrow from front to back, and provide “thin slices” of the bottom for
high resolution imaging.
• Side beams can search an area that is 720 feet wide (360 to each side), with a typical depth
performance of 150 feet when the side beam frequency selection is set for 455 kHz..
The main benefit of Side Imaging sonar to anglers is that it provides an overall survey of a large area of
water. This gives you a better understanding of the bottom topography and how structure is oriented for
more efficient fishing. Saltwater anglers pick up precise details of popular fishing structure like wrecks,
reefs, humps and drop-offs, as well as being able to spot bait balls in open water. Freshwater anglers can
see fish-attracting structure such as timber, stumps, rocks and creek beds.
