This Skimmer® transducer works with the StructureScan® 3D module (sold separately) to create a high resolution, three dimensional view of underwater terrain and fish-holding structure. Immediately see where fish and structure are located in relation to your boat, with a picture-like view you can easily pan, tilt, and rotate for the perfect perspective. The included bracket enables easy transom or step mounting, and jackplate or flush-mount step installation are supported via optional mounting kits.
