These new ling cod jigs have incorporated an internal rattle into the heavy 8oz head which in results so far have outperformed other jigs 4 to 1 in fishing trials! Lingcod are very aggressive territorial fish and when these jigs come along they really seem to piss off the Lingcod! Ling cod strikes are very ferrocious but when they hit these jigs it seems even Harder! When fishing for lingcod with these jigs we suggest fishing them them right on the bottom, jig them up and down banging them off the rocks to cause more noise and vibration. Make sure to hold on tight as that strike can surprise you! Tight Lines and Bent Rods!!
