SonarCharts ™ HD bathymetry map
For the benefit of our entire community, Navionics integrates sonar logs recorded by individual users with existing data to generate SonarCharts™, an HD bathymetry map layer which is great for locating fishing areas and revealing more contour detail. The continuous stream of sonar logs shared with Navionics ensures that SonarCharts™ reflects the ever- changing conditions of sea and lake bottoms.
I located some promising areas in the rocks after studying my new SonarCharts™ and landed some beautiful stripers after just a few casts. RICK, USA
