When I was making a map and using Preset style I use my fishfinder (Elite-4 HDI )and notice when I zoom into 100 ft it was ok, but when I went below 100ft to 50 ft it change the map all green with just contour lines ? are they away to be able to zoom down below 100 ft ?
the preset style was 2d vector ? Have not check my Gen 2 Lowrance yet ?
Thanks for any info on this

This is a known problem of all units with Indigo or violet OS like Elite /HDI/Chirp, Hook, if you use a raster.
HDS and Elite Ti have don't have such a problem (other OS).

Thanks
