SCREW DRIVE was sublimated into the plug for SW big game, paying respect to the existing freshwater plugs. After repeated a number of tests with target fish for big game, such as flounder, GT, and tuna, what we sought was an overwhelming appeals of "sound and bubbles" that we had not yet seen. The strong sound that cannot be produced by popper, much less pencil, is transmitted farther and deeper inside, and at the same time, the "bubble" that is created leaves the presence and lure's trajectory, playing the role of a fleeing bait fish. After two years of trial and error in the field, we have achieved satisfactory body strength with through-wire, stable casting distance, stable action, and the rotating performance of the prop fin which is the most powerful weapon. The unique "screw bubble sound" of SCREW DRIVE lures big targets in the ocean to the surface of the water.
