Locate fish easily in deeper water with the accuracy and clarity of the SeaFinder 480. The high-detail, 480 pixel x 480 pixel Film SuperTwist display on the 5" screen delivers clear images of what's below the surface, and the 16 levels of gray scale provide excellent picture definition. With 4,000 watts of peak-to-peak power, it has depth capability to 1,500 feet. The high-performance, dual-frequency 50 kHz/200 kHz Skimmer® transducer in the transom has a cone angle of 35°/12°, and it operates at boat speeds up to 70 mph. The FishReveal™ function exposes fish targets hidden in surface clutter, weed beds, thermoclines, and other cover, while the HyperScroll™ function locates and displays fish targets at higher boat speeds. Advanced Signal Processing (ASP™) automatically adjusts your settings for the best sonar picture, and the 16-level Grayline® separates fish from nearby structure and the bottom. The Advanced Fish I.D.™ shows underwater targets in different sizes of fish symbols, and FishTrack™ displays target depth readings above fish symbols. Surface water temperature readings come from a built-in temp sensor in the transducer. The unique display feature lets you combine a panel of sonar data readings with your sonar graph in one easy-to-read display. It also has back-up memory, screen and keypad backlighting and zoom with zoom bottom tracking and easy zoom-in/out control. Every unit is sealed and waterproof, and has selective on/off sonar alarms for shallow water and deep water, along with fish and zone. It comes with a one-year warranty.
