Williamson Lures Patented "Hook Lock" system provides perfect hook presentation and maximum strike efficiency. Multiple rigging ports for easy and varied rigging. Swims out of the package at 6 knots, no turning needed and will be excellent if mixed with a spread that uses a Rapala CD Magnum or an X-Rap Magnum.
