Why I Upgraded from the free government charts in my Navionics app
A short video demonstrating why I decided to upgrade from the free government charts in my Navionics app to the Navionics SonarChart option. Ridiculously better charts included detailed contours as well as lots of chart customization options - all in the Navionics+ option (the paid upgrade)...soooo worth it (as you see in the video).
