If your not set on a new unit since Lowrance doesn't make these anymore you can save some money and have some really great electronics. First a 520c or 522ic on the nose with split screen gps/graph and on the console a 510c Lowrance without gps. These locators have plenty of power and awesome colored detail. You can find these still being offered on Ebay and such and make a really good deal on them. I have a 520C on the nose and a 522I C on the console and have them linked together with an external puck gps ant..we are talking about a limit of $1000 only reason I am throwing this out..In my opinion you can't go wrong with these units.
