In order to produce the small sardines that Spanish mackerel likes to prey on, we devised an embedded swivel "pierce system" that can minimize the distance from the body to the blade. As a result, we succeeded in reducing the total length by about 9%. In addition, it is necessary to be able to keep winding without stress all day long in order to stick to the catch. Every detail has been devised to reduce winding resistance. "TG RUNNER" overturns conventional wisdom. Please try the jig that sticks to the catch anyway with the on-site principle.
