Trolling does not have to be a real drag with Fish Seeker! At 2.0 mph (0 .44 m/s), you can choose any trolling depth from 5 to 80 feet (1.5 to 25 m). Use for salt or fresh water fishing with 6-25 pound test line. A good replacement for outriggers and heavy lead ball sinkers. Simply choose the right setting for desired depth, let out enough line and troll at slow speed. Fish Seeker will flip over with each strike so you will fight only the fish, not the gear. Great for Salmon, Trout, Steelhead, Walleye, Crappie and Striper. Not for use with deep diving lures.
