Add a little rattle to your shake. Jig Junkie rattles add unique sound emitting capability to your jigs (jig must be equipped with a rattle collar or spider strap, sold separately). The sound emitted by the steel balls in these rattles travel great distances though the water. Fish sense the sound emitted by these through "earstones" called otoliths. These otoliths, located just behind the eye socket, are extremely sensitive to sound vibrations that can be detected great distances. We have three colors: clear, red, and black in two sizes: large and small. Fish Junkie jig rattles are packaged in packs of 10 for the angler's tackle box or 100 for the tacklecrafter.
