StructureScan 3D imaging scans underwater terrain and fish-holding structure to create a high-resolution, 180°, three-dimensional view beneath your vessel. With this unique imaging view, anglers gain a better understanding of where fish and structure are located in relation to their vessel. StructureScan 3D imaging is available on Simrad NSS evo2/evo3 and NSO evo2/evo3 displays, when used in combination with the StructureScan 3D module and 3D transducer.
