StructureScan® 3D allows anglers to see fish, structure and bottom contour in a stunning 3-dimensional view. StructureScan® 3D imaging scans underwater terrain and fish-holding structure to create a high-resolution, 180°, 3-dimensional view beneath your boat. With this unique imaging view, anglers gain a better understanding of where fish and structure are located in relation to their boat. StructureScan 3D works exclusively with HDS Carbon and HDS Gen3 series displays.
