I think the big 4 in Mississippi are all HD surveyed on the newest Lakemaster chip. You can go to their web site to check out what lakes are HD surveyed.
You can check out Navionics web app to see the level of detail you will be getting from them. With Navionics, you can get the whole country and free updates to the mapping for a year
