The Jig Rig set with pendulum sinker and Drop-Shot hook is ideal for predatory fish such as Perch, Walleye, and Pike as well as for Trout fishing using the smaller sizes. The pendulum sinker and hook swing freely from the spring-ring creating an unlimited radius of movement. Plastic baits can be skimmed along the bottom with this system. The hooks can be switched out as desired by using the attached spring-rings.
