The Jackall Seira Minnow is Japan?s latest. The ?i-motion? technique was developed exclusively by Jackall pro staff. Kept secret for years, Jackall is now releasing it to the market. When bait fish are not threatened, they swim straight. Jackall engineers have designed a bait to swim with no action needed. Just like real bait fish. Water actually passes through the mouth and exits through the gills like real bait fish which fish actually can sense. Feather on the tail of the rear hook helps to add stability to the lure. This lure has a weight moving system to cast farther and cover more water.
