The GIANT DOG-X SW is a real impact pencil that can appeal to underwater targets with flashing by performing a rolling dog walk accompanied by a shimmy. The hydro gills on the body generate sound and splash while cutting through the water surface during turns. Combined with the flashing during the shimmy, this lure has a powerful impact, like a fleeing baitfish, and can turn neutral fish into a feeding state. The weight setting, specifically for saltwater, derived from considering water engagement and action, generates a responsive action to rod work even on the wavy sea surface. It creates shimmy turns and splash sounds without jumping out of the water even during high-speed dog walking, appealing to marine fish. Furthermore, the increased weight has further improved casting distance. It boasts overwhelming fishing power even when targeting surface boils (nabura). Megabass GIANT DOG-X
