Shirasu that large horse mackerel and rockfish prefer to prey on. Shirasu, which is a general term for fry of sardines and sand lances, is a good bait fish because of its weak swimming ability. This "TIDE BEAT" was developed by paying attention to the weak vibration of Shirasu. By thoroughly verifying the small shad tail and finishing it extremely thinly on the body, we realized a high response enough to take action just by falling. In addition, it has an outstanding hooking rate because it easily bends in the mouth. The large carved ribs on the body, which are well-established in the peckering series, firmly grasp the water one by one to convey even slight changes in the tidal current to the angler's hand, making it easy to keep the range even when setting a heavier rig.
