The Luhr-Jensen Rattling Kwikfish K16 are 5 1/2 inch diving plug lures designed for salmon, steelhead, and lake trout. Kwikfish are full-throttle, wide-action, leave-no-doubt lures that challenge game fish small and large alike. Their aggressive action forces a response from fish, often generating the most savage strikes imaginable. This size is great for large steelhead and silver salmon as well as king salmon and lake trout. For maximum success, tune the screw eye on the face of the plug to achieve an even side-to-side action. Using small adjustments, turn the screw eye in the opposite direction that the lure is favoring, until it tracks straight. The Rattling Kwikfish K16 is rigged with size 3/0 treble hooks and dives unassisted to 15 to 17 feet deep.
