StructureScan 3D gives freshwater and saltwater anglers a unique, three-dimensional view of fish, structure and bottom contours -- making it easier to understand where fish and structure are located in relation to your boat. With StructureScan 3D, anglers spend less time searching for productive water and more time catching fish. StructureScan 3D is powered by a multi-beam sonar technology that not only produces picture-like, three-dimensional views of underwater structure and bottom contours, but also boosts the performance of two-dimensional Downscan and StructureScan HD imaging, providing views up to 600 feet to each side of your boat.
