In the current sea bass scene, a small wave (weak wave) type compact vibrator is the standard. It has the highest usage rate among the different types of amplitude, and is more versatile than any other type. Focusing on the lightness and operability that assists games with many rod operations, we pursue "trust that can be continuously thrown" in rivers, tidal flats, harbors, etc. The fast-winding, jerking, lift and fall required for assembling the day game are done lightly, and a stress-free body balance that makes tailing less likely to occur has been achieved.
