The ultimate vibration that combines high-dimensional flight and action «CALIBRA" has a stable posture during swimming, wide rolling vibration with a high fish collecting effect, and high castability. In addition to the castability that cuts the wind with the knife edge structure, the sound is strong against the thread and the bass system that has a proven record with large fish is adopted. Rather than a small rattle ball, the balance weight itself with a large mass is moved, and the bass accompanied by the wave due to a strong impact is generated. It is the ultimate vibration plug that breaks the conventional wisdom of vibration plug design.
