I have 2 6500 baitrunners and 2 4500 baitrunners, they are almost the same except the 6500's are a lot bigger. They are just like a normal spinning reel except the have a nice roller bearing on the bail so that the line doesnt get too stressed out on that roller. They have a top drag on the spool, and then the baitrunner, which is a lever towards the bottom of the reel the you turn on. This allows the reel to free spool, it also has a drag in the clicker so you can adjust to heavy current or for bite sensitivity. You can turn off the baitrunner 2 ways, one is by just reeling in, or you can flip it off with the lever. Like I said I have 4 of these reels and I will never get another reel. They do the job for me, and what I fish for. Hope this helps.
