Product Description

ShowDown 5.6 Digital Sonar System

With a snappy 8,000W, the uber-advanced, Showdown Digital Fishfinder has the power to provide an incredibly discerning 1/2" target separation, with plenty of juice to run a potent interference rejection system, as well as an infinitely adjustable zoom and auto bottom-lock zoom. Loads of features and functionality usually means a fish finder that's confusing to understand and operate. But ShowDown's simple intuitive operation makes threading waxworms onto your hook seem tricky by comparison. Think operating the ShowDown is easy? Check out the display_vertical, just like the water column. Top is the surface, bottom is bottom, and every signal in between is nothing but your lure surrounded by fish. Brilliant! And since there are no moving parts, batteries last far longer, running as quietly as a yawning minnow. 100% automatic, 100% digital-like a tireless silent assassin. Guys on TV use ShowDown for a reason-they demand the best, and so should you.
