Side Imaging Technology: How It Works
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 look out to a range of 360 feet to each side, with a total side
coverage of 720 feet, with a depth limitation of 150 feet.
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.
