Norihiro Sato, the founder of slow pitch jerk, worked on the development and created a new jig that he carved himself. The pull resistance is further reduced by making it a slightly extended design from the semi-long. Since there is less water biting, controllability during jerk has also evolved better. The goodness of the tide is also improving. The extension design slows down the fall speed, making it even easier to produce during feeding. A fall with a good tempo, combined with good controllability during jerk, creates a synergistic effect and makes a strong appeal to the target. It has an advantage even in situations such as doterra sinks, and it is possible to develop invitations with high fish collecting power regardless of whether it is green or deep sea. Targets are all fish species including yellowtail, amberjack, blackthroat seaperch and root fish.
