Now available through Navionics Freshest Data updating program is Navionics SonarCharts. SonarCharts provides an alternative perspective for boaters and fishermen who want more detailed depth contours for safer navigation or for targeting productive fishing areas.

We all ask for better cartography. We all want the latest data. Now you can contribute and see the new details the next day. Buoys change, sand bars shift, new rocks and submerged structures are discovered every day. So why not see them all with SonarCharts? The best part of all is it is a completely FREE service. All you need to participate in this program is a Platinum Navionics chart.



Simply upload your sonar logs and within 24 hours the new bathymetric data is on your Platinum chart after using Freshest Data.

It’s fast and easy:

>Record sonar using your GPS chart plotter
>Upload sonar logs to the Navionics World Application
>Navionics integrates the new data with existing data
>Download New SonarCharts within 24 hours!

Even if your favorite lake is not mapped you can now go out, record your sonar data and create maps for that body of water. This process will take a little longer than the 24hrs that the standard process takes. In order to participate in this program all you need is a Platinum Navionics chart.
