BaitRunner lets you fish with the bail closed and still let the bait swim freely. Just flip the lever to "BaitRunner On" and a secondary drag kicks in so that the reel is in tension controlled freespool. To engage the primary drag to fight the fish, just rotate the handle and the BaitRunner lever will flip to the "Drag On" position automatically. Super Stopper II anti-reverse, Dynabalance wobble-free rotor design.
