Although I subscribe to your theory of not relying on my GPS entirley, the C-Map is dead on accurate. I have the Standard Horizon GPS with the BIZER C-Map cartridge and the thing has every single buoy/island/depth/marina/etc. etc. etc. It uses the actual map file from the Bizer printed map itself. I actually went to his house and bought it from him. Great Guy, by the way!

I have boated (day/night) winnipesaukee for almost twenty years. The first 18 or so with my eyes and a spotlight. I picked up the GPS as an added tool to navigate. In the past couple of years I have watched it carefully during the day to assess its accuracy. I have been extremely impressed. Every once in a while the display puts me a few feet + or - on the other side of a buoy. That is usually due to satellite issues etc.
