Crank baits come in many different shapes and sizes although most cranks are short, flat, fat and round. These baits have tight wobbling actions that usually dive fairly deep. Crank baits come in various sizes but most are in the 3-5 inch range. Cast crank baits to structure such as rock piles and submerged weed beds.
