As a downrigger fishing weight, the Chrome Shark downrigger weight is the most effective cannonball ever made, its ability to track perfectly in deep water is unparalleled. But more importantly the Chrome Shark has emerged as a top contender against the leading attractors. The Shark cannonball is designed to attract fish to your lure from distances well beyond their visual range. It accomplishes this by targeting the lateral line of game fish, functioning on several levels; by creating and transforming energy into signals similar to those produced by baitfish. The highly polished concave facets on the sides of the Chrome Shark are the key to this ability.
