These rigs are specially designed for fishing pike and other large predatory fish. The linked barrel swivels are fitted with top-of-the-line Gamakatsu Treble 13 trebles and guarantee optimum hooking. The rotating barrel swivels offer maximum protection from predatory fish positions and ensure that the fish remain neatly hooked even during head shaking or spinning. Depending on the chosen rig, these are equipped with stainless steel pins that you press into the belly of the softbait and keep them neatly in place while fishing. When you hook a fish, the pins will come loose from the softbait. You can easily screw the head of the rig into the front of your softbait.
