"Light ! Not rise float ! Do not get tangled ! "
Tracy has thoroughly pursued ease of use by maximizing the "fishing" performance of iron plate vibration. By lowering the center of gravity of the body and the dolphin silhouette, we were able to achieve three things: lightness of pulling comfort, difficulty in lifting, and difficulty in entanglement. The lightness of pulling makes it less stressful even when fishing for a long time, the difficulty of lifting makes it easier to attack the bottom, and the difficulty of entanglement makes it less likely to fail in casting. It covers the shortcomings.
