Greg Myerson developed this sinker based upon the widely-known fact that striped bass, along with many other salt and freshwater species, initially rely on sound to discover prey. Add the RattleSinker™ to your line. Bounce the sinker near the bottom. Fish out of scent range or eyesight will hear this sound, come to investigate and then see or smell whatever bait you are presenting to them. More movement emits more sound and attracts more fish.
