The 12-inch Spin Doctor is the largest and most aggressive in action. Designed for deep-water, big-fish applications, it produces a wide, slow rotation that mimics larger baitfish struggling in the current. This Spin Doctor is ideal for targeting trophy Chinook salmon and is typically used at slow trolling speeds (1.5-2.0 mph). Because of its strong water resistance, it’s best suited for use with heavy-duty gear and larger trolling setups. If you’re looking to draw in fish from a long distance, the 12” Spin Doctor is the ultimate attractor.
