This feature enables the Blast Bone Jr. to remain in the ideal position and close to structure much longer, allowing bass to strike with pinpoint accuracy. The single-joint body design gives the Blast Bone Jr. a better range of motion, allowing the lure to move with a degree of up, down, left and proper movement. The addition of the soft tail provides an appealing swimming action and acts as a rudder to slow and stabilize the lures underwater movement.
