Two one-knocker mechanisms synchronize to generate tones of differing pitches. A large chamber in the head amplifies higher pitch sounds created with a stainless-steel bearing while a larger tungsten rattle in a smaller rear chamber generates a lower pitch. This also serves as a weight transfer system, enabling longer casts without tumbling which is a frequent flaw in other top waters resulting in more tangles and loss of casting distance.
