Jackall TN Lipless Crankbaits feature a Tungsten Mouth System on the outside lip that makes the lure stand up right when it reaches the bottom and creates more space inside the bait. More vibration and greater sound are created when this occurs. This system is well balanced for slow retrieves when severe conditions need more finesse. This bait casts quickly covering water efficiently. Jackall lures are created with the latest technologies in production and field testing. This ensures these lures are extremely effective with all kinds of gamefish around the world.
