Finding fish has never been easier. The FishMark™ 480 gives you the super-sharp resolution and clarity that tournament pros demand in a sonar, but at far less the cost of most advanced marine electronics. 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. LEI trolling motor transducer bracket included. With 1,500 watts of peak-to-peak power, it has depth capability to 800 feet. 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 separates fish from nearby structure and bottom. The Advanced Fish I.D.™ shows underwater targets in different sizes of fish symbols, and FishTrack™ displays target depth readings above fish symbols. Monitor surface water temperature readings with the trolling motor 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.
