Shimano BaitRunner BaitRunners have a second and completely independent drag that allows you to fish livebait more effectively. When the BaitRunner lever is pushed forward the normal drag system is completely by-passed. A fish picking up the bait can make an almost friction free run, until the angler flips the lever back, or turns the reel handle, to bring the reel into striking mode. There is also a tension adjustment knob at the rear of the reel.With flow and tension precisely balanced a problem-free run is guaranteed.
