I am considering buying a fishfinder, but I don't know much about them. I would like to pay less than $500. I was thinking of getting a color model. I realize this will be mainly opinions, but any info would help. If someone knows where to get reviews for them, that would be great also. It will be mainly used is smaller northern inland lakes and resivoirs for walleye, pike, smallmouth, ect. I have a '96 Bayliner 30ft Ciera cabin cruiser that is already equipped with a chartplotter/GPS unit.
