In the app you can flip from one chart type to another with a finger tap, and on a MFD you can window SonarCharts side by side with what Navionics sometimes calls their Nautical Charts.

But then again, SonarCharts are always packaged along with regular Navionics charts, and the Navionics Boatingapp he was using also offers a third "Government" chart choice in the U.S.

Apparently not, and Neil fairly points out how much Navionics brags about SonarChart detail in its marketing.
