Some variations of jerkbaits include suspending, floating, and sinking models, as well as lipless and jointed designs. Suspended jerkbaits are effective in colder water when fish are less active, while floating jerkbaits are good for shallow water and topwater fishing. Sinking jerkbaits are useful for deeper water and faster currents, while lipless and jointed designs can be effective in a variety of situations, depending on the fish's mood and behavior.
