Flatlander, I launched the PVC feeder at high noon on Monday. It is tied off the end of my pier in 9' deep water. I will let you know when I evaluate it. I agree with Bob's comments, but I have been trying to feed by hand and only carp have been responding. I'm hoping this feeder will get the fish feeding around the pier, then I will try and get them feeding on floating feed and then I will spend the big buck for the automatic feeder. And the feeder will pay for itself once I have bream, catfish and crappie all eating at the table. I do have cedars and willows weighted down around the pier. Anyway, that's my hopes and game plan. And yes, this is a private lake. But my brother n laws is on a public lake (Richland Chambers) and it really works well.
