The jigs are developed in such a way that they allure and catch fishes even from a distance or depth of 150 feet or more. Shimano Trevala rods have jigs that drop immediately to the ocean’s bottom with one swinging motion. The color and the form of the jigs are akin to certain fish species, that are being ate up by the base feeders of the ocean. The lively motion of the jigs of Shimano Trevala and other jigging rods in the industry is called action/reaction. This implies that the rod’s jig does not only allure fishes that are searching for food, it also tends to make other fishes attack because of the sudden movements of the jig. The Beginning of the Shimano RodsThe start of the agency that makes Shimano rods took place in Osaka, Japan, in the year 1921.
