Satellite Overlay and SonarChart Shading Updated and Expanded

Satellite Overlay and SonarChart Shading Updated and Expanded

For coastal and inland boat owners who want to know as much as possible about depths and bottom structure, Navionics SonarChart™ Shading presents a detailed rendering of the seafloor and lake bottoms. And now it’s better than ever.

Now available within Europe and North America, this update to SonarChart Shading content, derived from a more recent version of SonarChart, incorporates depth data from a massive amount of sonar logs contributed in the past year and offers expanded coverage further from shore. Additionally, satellite imagery has been carefully reviewed and optimized using higher quality images to provide a clearer top-down view and better situational awareness above the waterline.

On our exclusive Platinum+ cartography products, Satellite Overlay and SonarChart Shading forms a single overlay which can be updated using the Navionics Chart Installer. An active subscription is required.

Introduced recently to the Navionics Boating app, customers with an active subscription need only to download their area of interest, turn on the overlay and start exploring.

As coverage areas are released, customers who own the Navionics Boating app and Platinum+ with an active subscription will be able to download the updated overlay.
