Here are 10 sets of brand new Rock Cod Squid Rigs. Our Rock Fish Rigs (3.5 inch bulb squid) are rigged with two bulb squids per set. These rigs take advantage of the natural instinct of a saltwater fish to feed on squid, one of the most plentiful baits in the ocean. With five colors to choose from, these are sure to be a hit with any fisherman heading out to their favorite rockpile, reef, or pinnacle.
