A good shad shape, an amazing roll action and a special 2-tone technology. The Keitech Shad Impact is the perfect imitation of variuos kinds of minnows. The unsymmetrical body is what creates the good roll action that can be effective for bass. The Shad Impact has 2 kinds material. In the upper side(dark color) there is no salt material and the lower side(light color) has salty material. We find this is the best combination to make the roll action and flash. It also features a slit on the back and belly side for off set worm hooks.
