The device attaches to the knob of a regular bat. When you swing correctly (hands inside, knob to the ball, extension through contact), the hinge stays locked straight. If you cast, loop, or drop your hands/barrel, the hinge folds or bends , providing immediate tactile and visual feedback.
What Is the Line Drive Pro? The Line Drive Pro is a batting training aid designed to enforce a short, compact, and direct swing path to the baseball or softball. Unlike heavy resistance trainers (e.g., Don Slaught’s RightView Pro), the Line Drive Pro uses a lightweight, collapsible hinge mechanism.
