The features of the Humminbird 587 are state of the art, however the base map called a UniMap, I believe, needs to be supplemented with one of the available accessory mapping programs.

Humminbird offers a series of maps they call LakeMaster. There is one for our region, but it is mainly for inshore freshwater fishing lakes and locations in our area. They also offer a Navionics South, but it is featured as a multi state lake maps. I don’t believe that either of these products would serve your southeast Louisiana salt water marsh fishing.

Try calling the Humminbird support section at 1-800-633-1468 and see what they recommend for the salt water marsh area of Louisiana.
These supplemental mapping programs will run the better part of $150, so just don’t get the first one they recommend. After getting their recommendation, go to a stocking Humminbird dealer and ask to see the recommended map(s) in Humminbird GPS unit. If they have the map, zoom in on your fishing areas and see if it gives you the detail that you want.

That way you will know what you are getting and if it will serve your needs.
