OPTIONAL CHARTS FOR THE LOWRANCE HDS SERIES
~ Captain Paul's response to: ~ Steve A ~
The Lowrance HDS series come with a base map that is what the map name implies, a basic map of the entire U.S. coastline. Most uses opt for one of the accessory maps that are designed for the unit.
They feature the “Lake” maps, but as you surmised that these lake maps do not cover the Louisiana Marshes. For that you will need one of the other programs that are basically marine charts. One of the HDS 5 models offer a Lowrance Insight mapping system. (HDS-5M). That is one of the options you may find that is available as a separate option if you did not get the “M” model.

Navionics offers their Platinum SD/907p+ or their MSD/907P+. These Coastal charts are not cheap as they cost about $400, so go to a stocking Navionics dealer and check out the details on the maps before you plunk that kind of money. You can get an idea by viewing the Navionics web site at

Other maps may do, so do your homework before investing in such a system.
