This bait imitates a floating smelt. It floats at 45 degree and the body rolls by waves and winds, so you do not need to make any movements by rods. Let it drift and it automatically gives the fish a image of dying smelt. For better hook penetration, the stem extension does not let the hook touches the body. The hook also works as pendulum so the body rolls more. We put the TMC MORPHO FIBER on the tail part. The Morpho Fiber is a structurally colored material that mimics the mechanism that causes the scales on the wings of the Morpho Butterfly to show color. Its natural and delicate self-illumination and its movement attracts fish. Painted a orange mark as a indicator so you can spot the bait.
