The PC-Planner from C-map turns your home computer into the perfect navigational planning tool. By using the same NT or NT+ C-cards you use on your boat, you can now display any electronic chart in full color on your computer screen. Quickly view your chart data, create and edit routes for your next trip, or measure distances between your favorite ports - all from the comfort of your home. C-Map's newly added SelectMarks, designed exclusively for PC-Planner, lets you locate specialized areas such as fishing, diving, and wreck sites. With C-Map's RAM card, you can even download waypoints and routes to your plotter. Note: Check with your chart plotter for manufacturer compatiblity.
