I am looking to buy a new GPS/Fishfinder combo unit for my boat. I don't want to break the bank...I would like to stay in the $500.00 range. I want a decent sized color display. There are several manufacturers that seem to have nice systems. I have looked at Humminbird, Lowrance, Garmin and Eagle, and I just can't decide which is going to be the best for my money.

Whichever system I decide to go with, I will need to also get the map chip for the East Coast (Potomac River / Chesapeake Bay).

Does anyone have any suggestions or thoughts about a GPS unit that they have seen in action?

Thanks!

I have heard good things about the Lowrance LMS 522's

Lowrance LMS 522 is a nice looking unit with a lot of bells and whistles. I wonder how it would compare to a Humminbird 757C. Well..here are a couple of the major differences between the two...jeez..this took a little longer than I thought it would..and it's not very pretty either!

The winner of each comparison is denoted by a " *** ". See below....
