In-line Spinners work well for northern pike. If you are just looking to catch some pike, the smaller spinners in the 3 to 4 inch range will catch plenty of smaller pike with an occasional big fish, especially during the spring. When you fish with the larger spinners, you won’t catch as many smaller pike, but you will definitely catch some bigger pike. In-line spinners work great in shallower water near weeds, but you can also use them on a Carolina rig to fish these in deeper water.
