The ultimate movement trailer combines the best of two worlds for a hard-flapping action. The addition of Zoom's patented Ultra Vibe tails to the back of a traditional chunk-style trailer makes the perfect addition to any flipping jig, swim jig or vibrating jig. Despite the appearance of a slim profile, these tails move tons of water on both the retrieve and the fall, giving the fish a sound profile they haven't yet experienced in this lure class. Salt impregnated. Size = 3".
