An original assist line designed with the concept of appealing underwater! This assist line is color-tuned to around 480nm of visible light, which is said to be the easiest color to pass through underwater. Just like the jig itself, the assist line can be used as part of the silhouette to appeal more strongly to the target, increasing the reaction distance of the fish. In other words, it is an assist line designed from a completely new concept that makes it possible to appeal to fish further away. It is possible to create various assist hooks with two patterns: one with fluoro core and one with knot type.
