10 Inch

The 10-inch Spin Doctor is a favorite for targeting larger fish, especially king (Chinook) salmon. It creates a stronger, wider rotation that generates more water displacement, helping attract fish from greater distances. This size is best suited for slower trolling speeds (1.5-2.5 mph) and is often paired with flies, meat rigs, or whirly gigs  setups. Its larger profile works exceptionally well in deeper waters and murky conditions where fish rely on vibration and movement to locate bait.
