455/800 kHz Skimmer DSI imaging transducer

This Lowrance Mark-5x DSI Fishfinder incorporates innovative DownScan Imaging Sonar technology into an affordable stand-alone fishfinder. Exclusive DownScan Imaging on the Lowrance Mark-5x DSI fishfinder displays photo-like views under the boat, making it easier than ever to choose the best place to drop a line. DownScan Imaging exposes thermoclines, clearly distinguishes between large predators and schools of baitfish, reveals bottoms as hard or soft, and allows you to easily recognize structures like ledges, vegetation, and wrecks that were once muddled below the water. 455/800 kHz Skimmer DSI imaging transducer has 4,000W peak-to-peak/500W RMS power, down-looking crystal, internal temperature sensor, a maximum depth of 200', and impressive bottom readings at boat speeds up to 40 mph (optimum images appear at speeds under 8 mph). The Mark-5x DSI fishfinder includes adjustable backlit screen and keypad, TrackBack for accessing multiple pages of sonar history, and simplified easy-to-use menus. Also features bright-white 5" 480 x 480 pixel Film SuperTwist LED display with 16-level grayscale for maximum visibility and contrast.
