Is this basically the same product as Maptech Offshore Navigator that
uses the raster charts in BSB format? If so, I've been using it for a
long time and highly recommend it. It has very much the same look and
feel as using paper charts only a lot faster, more convenient and lots
of added features. The only negative I have is the inability to zoom
into the same level of detail as a good chart plotter can. I use my
chartplotter side by side with a laptop runing Maptech to get the best
of both worlds.
