The shapefiles are generated from Reefmaster with an U_Limit of 19. On a HDS 5 gen 2 the colours show up at the 2 km level (2 km on the scale in the right lower corner), on my HDS 7 gen 1 I have to zoom to 200 m before the colours show, and on a Simrad NSE 12 I have to zoom to 20 m, which is way too much to be useful. When I view my vector maps on different units the zoom level at which the colours start showing differs a lot. GOFREE C-MAP (INSIGHT) Genesis & INSIGHT MAP CREATOR Support > IMC Support
