Eco Pro Tungsten Heavyweight Football Jigs offer many advantages over lead jigs. The football jig is designed to be fished deep, where sensitivity is key. Because tungsten is so much more sensitive than lead, you will feel the subtle changes on the bottom that you would have never felt before. It lets you feel more strikes and catch more fish! Special seal coat painting and super premium needlepoint hooks make the Eco Pro Tungsten Heavyweight Football Jigs the best on the market, period.
