This is a great tool to locate fish. Spinner Jigs and Trailers create an array of flash in the water, attracting gamefish from greater distances. The connection points create a simulated underwater school of bait-fish. This Pre-Rigged Pro Umbrella Rig comes with a depth chart to ensure you are fishing the depths that you want. This is an excellent tool for striped bass, bluefish, Spanish mackerel, and other game-fish. It can quickly turn a bad day into a productive day on the water.
