A special jig head that is perfect for dart techniques using the Coreman worm "Alkali", which continues to produce high catches at the forefront of seabass day games. Even with light power, the jig head rig can be made to dart greatly in the water. While it has the ability to keep the range firmly, it is characterized by low jerking resistance. This is a big advantage as it reduces fatigue even in long games. * The hook is a special Coreman original, CJIG-TF #1/0 (HOOKLABO special order) with an extremely low friction coefficient fluorine resin coat.
