The Bouncing Betty is a lead-free alternative to steelhead and salmon drift fishermen, Carolina rig bass fishermen and slip sinker walleye fishermen as well. The very dense rubber provides the weight necessary to get lures and weights to the bottom fast while maintaining just a bit of "spring" that keeps it from hanging up in the rocks. Four sizes suit a wide range of conditions and depths. Hangs-up less and drifts in slow currents better than lead sinkers Perfect for Carolina rigs in rocky conditions
