Side Scanning Sonar

[Big Water]

It's pretty obvious that where you find bait balls, you're catching fish. This past weekend at Olcott the fish turned off like a light switch during high sun. However, we hit a massive bait ball and the riggers started popping. Since the bait balls are pretty scattered, I wondered how much benefit there would be to a side scanning sonar????? If these things really shoot out 200-300 feet, you could see when you're passing one and turn to intercept it. Anyone use one? Results?

Thanks,

Doug
