High Def detail
SonarCharts™ is an HD bathymetry map featuring extraordinary bottom contour detail, great for increasing awareness of shallow waters and for locating fishing areas at any depth level.
A community benefit
Navionics integrates the continuous stream of sonar logs shared by individual users with existing data to ensure SonarCharts™ reflects the ever changing conditions of sea, lake and river bottoms.
SonarCharts™ is viewable on Humminbird. Lowrance, Raymarine, Simrad and B&G. For other brands and models check our Compatibility Guide. Learn more about GPS chartplotter compatibility, how to view SonarCharts™ and how to record sonar logs (Humminbird and Garmin sonar logs can be processed now; others coming soon).
