Pline Diamond Jigs. Choose Between 8oz, 10oz, 12oz, 16oz. Diamond Jigs have been a Saltwater favorite for many years. The versatility of this lure has made it universally effective for almost any type of deepwater jigging application. P-Line has added a holographic laser finish, which gives this particular style of bar even more fish attracting flash. Whether you’re fishing for Halibut in Alaska, Grouper and Cobia in the Gulf, or Ling Cod off the California Coast, you’ll be satisfied with the results of the new P-Line Diamond Bars.
