I'm hoping to get some recomendations for a unit for the front of my boat (16' Tracker).....I fish only larger ponds and small lakes with the boat so i very rarely have the motor going (once all last year, of course most of these waters are electric only) I have a small humminbird at the wheel but its really not working well and was just going to invest in a better one to work off the trolling motor since thats where im always at.  I've got about $450 to spend and really dont know what would be a good one to put up there....Im guessing i wont need GPS,  Color would be a good thing and a good readable screen in the sun....Any guidance is appreciated
