I understand the birds are 640x640 and stronger pixel count? Are the Lowrance clearer since they use dedicated crystels or is this of no concern. I also understand if I want side scan I must get the GPS. Seems like alot to pay for something I may not get much use out of. Feel free to tell me if I don't know what I am talking about, beacuse I probably don't. Thanks for any information or comments
