StructureScan 3D imaging scans underwater terrain and fish-holding structure to create a high-resolution, 180-degree, 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. The picture-like, three-dimensional views are displayed on the Simrad NSS evo2 and NSO evo2 echosounders/chartplotters, when used in combination with the StructureScan 3D Skimmer transducer and module.
