How well does your electronic charts identify the various color zones???

[Piscatory Pursuit]

I have heard many complaints from folks about their electronic charts not doing a good job of identifying various color zones like the Green Zones. Is there anyone out there that likes the way their charts identify these zones?

I was on a boat a couple of months ago sporting a Furuno GP7000. It shaded in the green zones etc. exactly how they should be displayed. I think it has more to do with the plotter rather than the chart. It was using C-Map cartography and I still prefer Navonics for much more detailed contour information. I am not working in the Great Barrier Reef area though.
