Maptech's new GPS planning and navigation software has the best cartography with all raster, vector, contour 3D, photo, topo, and more
Very easy to install with their new USB flash drive installation.
Pros: I really like the bathymetric 3D Contour Charts and the use of NOAA raster charts. Easy to use and great tech support.
Cons: Limited chart coverage outside the US and Canada. Sometimes it is hard to use on a laptop because of the sun glare. Be nice to have this on a daylight readable screen.
Overall: Finding greatotherwise unknown fishing spots.
