I was watching OLN this weekend and Bill Dance was selling this Underwater speaker system that emits the sound of fish schooling and eating other fish. To me it's about the same thing as a Robo duck. I definately understand the desire to catch more fish, and shoot more ducks, but you have to draw a line somewhere. I think electric powered gismos is best place to draw the line. I am still waiting for the Robo Ducky Feris Wheel to come out!
