The Megabass DX-Free 3.0 lure features a patented balancing system consisting of a free-moving tungsten ball. The ball has three positions, each serving a specific purpose. In its initial position in the tail of the lure, it allows for accurate and long-distance casting. As the lure is reeled in, the ball shifts to the front, quickly reaching the desired depth. The lure then maintains a stable, high-frequency movement as the ball slightly moves towards the center of the body. With a maximum operating range of 3 meters, this lure is designed to provide optimal performance in any condition.
