Panther Martin Spinners are the world's easiest and fastest spinning inline spinners thanks to their signature shaft-through blade design. This simplistic approach minimizes the use of unnecessary hardware on the lure, ensuring proper blade rotation time and time again without fail. The Convex/Concave spinning blade sends out a subtle vibration and flash that predatory fish will find irresistible. The heavy weighted bodies will aid in casting distance and running depth, allowing you to cover large amounts of water with this highly effective presentation. Each Panther Martin Inline Spinner features a razor sharp premium quality treble hook designed to keep fish pinned.
