Re: Which Chartplotter do you own?
Garmin gpsmap 420X, the X being weather... discontinued last year.
I don't like garmin in general because of the difficulty of getting maps onto it and the price of the garmin ones, but this one has some decent built-in cartography, plus the satellite weather option, for $400.
The screen is excellent, bright and readable. The maps for most lakes are decent. Unfortunately the map for Lake Superior is an extra $300 plus shipping.
I plan on getting a big screen chart plotter at some point, but right now the garmin is ok.
