I feed from a Polaris 900 Ranger and that is the dinner bell for my fish. I never tried a bell, but I would gess it would work. Some of my BG will come when they hear my footsteps on the dock.
A half coffee cup feed might be plenty to start with. Just enough to get them started. No need to waste it if they are not cleaning it up. But it will not take long to get them started eating. Seems like once a few get the idea, the rest sense a feeding frenzy when they realize some fish are eating and they are not.
