Had some time to use Sonar Chart Live on my GPS/Sounder yesterday. I was around Kiawah and noticed on my sonar charts (1ft contour fishing charts) on my mapping card that there were navigational contours, but no sonar chart contours. So did some crossing patterns and pretty much mapped a good bit of the area. I have uploaded these into an update and should be available for others to update their chart cards in a few weeks! Really easy to use feature, goes into updates, and you can use the info right then and there! Use every tool to your advantage!
