It shimmies, it darts, it swims, it runs for its life only to be overtaken and mauled by big king salmon. That's the life of a J-Plug. With free sliding swivel-chain rigging located in the head of the lure, the buoyant body is allowed the freedom to swim with the reckless abandon that draws the attention of predators, even at the fastest troll speeds. The color selection is vast and includes a wide array of Everglo finishes for attraction at day break and sunset, when salmon are most active, along with deep water depths where visibility is limited at all times of day.
