The Jackall TN Lipless Crankbait features a Tungsten Mouth System on the outside lip that allows the lure to stand straight up when it hits the bottom making it perfect for falling through holes in the grass or on yo-yo retrieves. This gives more vibration and a large echoing sound. Also this makes the TN great on slow roll retrives keeping it straight but still putting out vibration. This bait casts like a bullet even in the wind helping you cover water or make ultra long casts when fishing clear water.
