Lowrance, Simrad StructureScan 3D module No Transducer

For the first time, StructureScan® 3D allows anglers to easily see all underwater fish-holding structure and the fish as if they were fishing underwater. Eliminate confusion when fish aren’t on the banks and in shallow, visible cover. Now, a slow idle over a potential area quickly lets you master bottom contours, identify a vertical break or secondary point, and catch more fish in and near the main deep water channel. Transom mount and through hull transducers avalable.
