Transcend the ideal "Both snagless and hooking performance" The cover jig is a lure that requires performance under extremely harsh usage conditions. There are many types of covers, from natural covers to man-made covers, which change shape during the four seasons. Under such circumstances, it is a good condition for the cover jig to be hard to take root under all circumstances. However, if the number of brush guards is increased in order to improve the snagless performance, the hooking performance will deteriorate. In order to improve this, we thoroughly researched the brush guard from the ground up. As a result, it was found that it is best to efficiently arrange the required number of guards in the horizontally long holes, instead of simply planting guards in the holes of a perfect circle.
