The New Pro Senko has been designed with a thicker head area to help it stay on the hook when used with Gary’s Swim Jig or other Shaky-Head style jigs. It still possesses all of the original Senko’s incredible fish-catching action. The Pro Senko also casts like a bullet due to its unique design and gets into the strike zone quickly. Available in a wide variety of colors, there is a Yamamoto Pro Senko up to the task. 10 per pack.
