Navionics added a cool new feature onto their Platinum+ & HotMaps Platinum cards, SonarCharts Shading. The Sonar Chart Shading takes the one-foot contours and turns them into high definition relief maps in the Satellite Overlay layer. You'll be able to discern depth changes at a glance. #Navionics #SonarChartsShading #1FootContours

For the month of May, the Navionics Platinum+ & HotMaps Platinum are also on sale so great time to pick up a new navigational chip!
