The extraordinary fish-catching ability of the Panther Martin Spinner has been verified time and time again in the past 5 decades. Its famous convex/concave blades send out sonic vibrations that are proven to attract fish! The weighted body makes it a true countdown lure, and ensures that it'll cast like a bullet for you. Because the blade is directly mounted to the shaft, it spins faster and more easily than other designs. Super-sharp hooks keep fish caught!
