Download the Lowrance dat file

This file (called RMMDL.dat)must be extracted  and be renamed to insightmapcreator.dat, and placed in the insightmapcreator folder to replace the existing file. Be sure to back up your old one. The new one contains codes and icons for Bottom hardness, structure, new vegetation colours etc. These are all linked from GME via shpdefault.dat and the anglingcharts skin.
