With a snappy 8,000 watts, the uber-advanced, Showdown Digital Fishfinder has the power to provide an incredibly discerning 1/2-inch 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.
