Whether plying the deep lakes for salmon, sinking a ribbonfish for a smoker, or trolling the cold waters of the Pacific Northwest, Penn Fathom-Master® Downriggers are the downrigger of choice due to their reliability and durability. Available in both a 24-inch or a 48-inch boom, Penn Fathom-Master® Downriggers were designed for both freshwater and saltwater use. Made only with the finest materials for corrosion-resistance and performance, Penn Fathom-Master® Downriggers are a common sight on charter boats throughout the Great Lakes and Pacific Northwest, and tournament boats of the SKA. Do you think that these captains would trust their equipment to just any downrigger? They have chosen Penn because it works, day after day, trip after trip, tournament after tournament.
