The unique wobbling and rolling action of the spoon makes the trailer move seductively, so the Caro System effectively appeals to horse mackerel just by reeling it in. It can hit areas that a single jig cannot reach, and it creates unprecedented vibrations, so it is effective against horse mackerel that tend to get tired of single jigs. In other words, just cast and reel it in, and no difficult actions are required, so anyone can easily catch horse mackerel with this Caro.
