The Baku Baku design uses a head shape with a low center of gravity that creates a resonance as it moves through the water. Its shape also produces a complex flow of water behind the head, which in turn, creates a unique fish-attracting action from the silicone skirt. The introduction of the 3D holographic Kyorin / SCALE BOOST design on the head, along with the 3D holographic eye, further enhances the fish-attracting properties of this soon-to-be classic. The Engetsu Baku sinks quickly and can be used vertically, or semi-horizontal along the bottom with a lift and drop technique.
