The line eye is separated from the body, resulting in a more natural movement compared to conventional jigs. This design allows for a significantly larger range of motion, realistically replicating the movements of baitfish like sardines. The jig swims with a rolling motion, swinging the body left and right. It also performs reversal slide actions during one-pitch or slow-pitch jerking, effectively triggering reactions from fish. The free-moving structure enables lifelike falling actions, which stimulate the predatory instincts of target species. This unique movement makes it ideal for targeting a wide range of fish, including Isaki, Spanish mackerel, flatfish, rockfish, bluefish, sea bream, and more.
