It is time to pick a new sonar unit for my new war Eagle 542. I want to spend from 1-400 on a unit. I have already had the Lowrance mark 5x and disliked it very much. I thought my Eagle 480 was a much better unit. I even called Lowrance on the phone while on the water last winter and they could not get the 5x to pick up my jigging spoon on the screen. I want to be able to see it fall in real time to schools of fish...How about some input...Thanks...i have heard good things about the new Garmin and Humminbirds...
