It is invited by the rotation of the screw and the slight vibration of the tail.
The design is similar to Masu-no-Koeda, but the action is completely different.
The two front sections are connected by a metal shaft, and by setting a screw with the mounting hole offset from the center line on the shaft, the vibrations caused by the unbalanced rotation are transmitted to the two rear sections connected by a thread, causing the tail to vibrate finely.
The thin resin screw rotates firmly even in a dead slow roller ring, appealing to trout with its visual sense, water movement, and slight vibration of the tail.
