The Hybrid Edge square bill enables the MB-63F to dive to depths of 3 to 5 feet while creating a dynamic swimming action with a tight wobble that's irresistible to trophy fish. The one-piece internal molded weight within the Macbeth concentrates the lure's center of gravity to allow it to recover faster while running true during various retrieval speeds. The Hybrid Edge square bill also provides durable performance that's ready to tackle the gnarliest of natural and artificial environments as it deflects off structure in anticipation of the next big bite.
