Soft and hard. The evolved jigger awakens its predatory instinct. A spinning model of the new Osea Jigger that deeply pursues the essence of jigging, ``manipulating the jig at will'', and has evolved two characteristics. "Quick Jerk" has improved response due to its high elasticity, and is specialized for fast-tempo invitations and sharp jig actions. It is possible to produce accurate jig action even under doTERRA drifting conditions and fast current conditions. By making the tip flexible while increasing the repulsive force, it follows the constantly changing tension, making it easy to grasp the timing of jerk, and adapting to slow and fast combination jerks and small invitations. "Natural Jerk" has excellent flexibility due to its low elasticity, and is specialized for smooth jig action and slow invitations. In addition, even in shallow areas or in situations where the current is slow and the tension is transmitted too directly, it is possible to produce a fascinating jig swimming. The strong bat shows its true value when bent, and it also has the ability to produce a wide sliding action.
