Get the most power and resolution you can buy. I have heard decent things about the birds, but I use lowrance in my boat.
he's not so much a Lowrance snob that he wasnt thinking of buying one of my birds. i got two of them and love them. if you have the money get a 787 or higher with gps. i got nothing agains Lowrance though. they are all good finders and get the job done if you take the time to learn how to use them.
