Humminbird Coastmaster Map Chip

Anyone have experience with this yet? Trying to determine coverage for intra-coastal waters/sounds like we have here in NC. Humminbird has a shaded map on description which appears to indicate some coverage but hard to discern what exactly is covered and how far in.

I just got the Florida chip and am looking forward to using it in my center console bay boat around Tampa and in the Keys. It appears to have a lot of lakes included. hmm
