Can someone explain how and why you'd want a bait clicker on your casting reel? I looked at an Abu Garcia (forget the model) with a bait clicker switch, but the best I could tell, the bait clicker part only "did something" if your drag was loose enough that a fish could pull out line and make it click. Which seemed to imply that you had to tighten the drag before you could reel anything in. So I shied away from it and bought a different Abu Garcia model that didn't have the clicker. But now upon reflection, I'll bet I didn't understand how the whole bait clicker mechanism is supposed to work, because it seems silly that you'd have to adjust the drag with a fish on. So what's the benefit other than the obvious audible indicator of a bite?
