Lowrance, Simrad StructureScan 3D Transom Mount Transducer

The StructureScan 3D transducer produces three-dimensional scans of underwater terrain and fish-holding structure to create a high-resolution, 180-degree, three-dimensional view beneath your boat. 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.
