SCALE BOOST Durable Elastomer Tail (3 x Included) Sinking and Floating Models 99mm - 3.9in Arriving from its proving grounds in Japan, the battle-tested BT BAIT is now available in North America in both slow-sink and floating models. The multi-jointed swimbait has three hard body sections and a durable elastomer tail that produces natural swimming action regardless of speed on retrieve. Boasting Shimano’s SCALE BOOST technology to conjure an incredibly lifelike appearance, the BT BAIT is perfect for finesse enthusiasts who enjoy "matching the hatch" with a light spin or bait finesse system (BFS).
