Real-world use and features

Plan shore-to-shore trips with confidence by visualizing marinas, docks, and ramps, while staying aware of shallow areas and hazards such as shoals, rocks, and wrecks. The added depth detail supports route planning and anchoring strategies, and the integration of tides and currents helps with timing for passages and water levels. Roadbeds, foundations, bridges, brush piles, culverts, and creek channels become identifiable markers for productive fishing or safer navigation, depending on your activity.

Live data and updates

SonarChart Live enables real-time 1 foot bathymetry maps on plotter or mobile, with sonar logs uploaded to Navionics for ongoing refinement. The charts benefit from around 2,000 daily edits drawn from official sources, community contributions, and user surveys, ensuring a dynamic, community-informed dataset. Plotter Sync and Dock to Dock Autorouting deliver additional convenience on select Raymarine models, while Nautical Chart and SonarChart come preloaded for immediate use.

Getting started and ongoing access

Charts are preloaded and ready to use, with daily updates and Community Edits available for one year. This combination supports ongoing refinement and local knowledge sharing, helping you tailor maps to your preferred vessels, routes, and fishing patterns without demanding a complete system overhaul.

Note on expectations

While the data can help inform decisions and improve planning, results depend on conditions on the water and user practices. Navionics emphasizes up-to-date information and community input as a way to enhance situational awareness rather than guarantee outcomes.
