C-Map is better than Navionics when used in some niche cases, like fishing in new areas, or worldwide cruising. Navionics is better than C-Map for typical use by recreational boaters due to its local details and community functions. I knew I wanted to use one of them on my boat, but I just couldn’t decide which.Īfter extensive research and testing, I have finally come up with an answer. I actually purchased both products myself so that I could do my own independent comparison as well. In a recent poll on my YouTube channel, I had over 2500 votes, telling me that Navionics is 3x as popular as C-Map.
