The extremely small silhouette and tight action of the high density tungsten are effective against hairtail fish. In addition to the basic one-pitch jerk, the ability to attract hairtail fish with short pitch lifting and tension fall is a noteworthy point. Also, like the original model, the ultra-high density tungsten body with a specific gravity of 18.15 has an extremely compact silhouette, which means it has a high bite-inducing ability for hairtail fish that prey on small baits. The color lineup has also been reorganized to suit hairtail fish, making this a series that can be strongly recommended for hairtail fish jigging using tungsten jigs, which are becoming mainstream in bays all over the country.
