The Jackson Sea The Mackerel Rigged is a quality shad that features an integrated, very sharp hook. This makes the shad super fast and easy to use. The shad is an imitation of a mackerel, a popular prey among many saltwater predators. Due to the large paddle tail the shad moves through the water with a great action. Several rings have been added to the shad, which are ideal for attaching a stinger, for example.
