I went to a seminar last January, much to Fishkillers recommendation. The presenter was Lance Valentine. His first statement was " fish where there are fish" and " it may or may not be where the other boats are". But lets admit it its tough to look for fish. Everyone wants to get a line or two in the water as soon as they can. He had a LOT of information on how to set up your sonar to get the best information. But this is Key.
