SpotlightScan™ Sonar delivers a new level of angler-controlled, surround-scan views to provide picture-like images of key fishing areas on your HDS Gen2 or HDS Gen2 Touch fishfinder/chartplotter display. Similar to the way a scanning spotlight reveals objects in the dark, SpotlightScan™ Sonar clearly pinpoints structure and fish targets ahead and around the boat, so anglers save valuable time on the water and maintain focus on the most productive fishing spots – all without disturbing these areas before you have a chance to fish them.
