Innovative design allows the Spin Doctor to roll properly and effectively at speeds from near zero to speeds upwards of 4 mph. This speed tolerance has revolutionized Great Lakes Salmon Trolling by allowing fisherman to integrate highly effective rotators into their spread of spoons and plugs. Long gone are the days of having to choose between an all Dodger Program or all Spoon Program. With the Spin Doctor, you can always include the effectiveness of a rotator in your spread. Charter Captains across the Great Lakes make sure that a Spin Doctor is deployed into their spread.
