Here are 12 packs of 3/0 Green/Yellow Rock Cod Feather Rigs. The ROCK COD RIGS are good at catching rockfish. Attach enough weight to the snap swivel so the rig can be lowered to the bottom. For best results, use a lead or metal bar type jig as your weight, or attach small pieces of squid to the hooks themselves. A slow vertical jigging motion will induce the most strikes. From Mexico to the Pacific Northwest and Florida up through Canada, these rigs are widely used by anglers for vertically jigging cod, rockfish, batfish, smelt, croaker, and various similar fish. Swivels attach at each end of the rig. The strengths (lb.- test) of the main line is 60lb and the branch line is 30lb. All rigs are supplied in a convenient " One-Pull" dispenser package.
