I was not impressed with what it offers. The fishing chart shows some detailed depth contours and I have used that screen on many occassions. Other than that I really don't use any other screens that the G2 chip provides.
I was going to get one for my 4212 and after running a boat with one installed on 5208.....I would definitely NOT get one, it slows down the redraw of the chartlotter dramitically making navigation without an autopilot very tough!
