Learn how to record sonar logs using your Humminbird, Lowrance, Raymarine, Simrad, B&G, and Garmin equipment (video). Save to any card and upload. Plotter Sync is a simpler alternative, but the easiest, most impressive and automatic process is with SonarChart™ Live described below!

SonarChart Live!

Use your plotter/sonar or mobile device to create personal 1 ft/0.5 m HD bathymetry maps in real time with SonarChart Live. See webinar and this video.

Upload from your boat!

Raymarine Wi-Fi device users don’t need to remove a card from their plotter to upload sonar logs. They can do it directly from the boat using Plotter Sync. This advanced feature also allows transfer of routes/markers, download of new areas and updates (webinar), and activation of a new Navionics+ card. Raymarine MFD and Dragonfly PRO users can more conveniently perform sonar log uploads with SonarChart Live.


See the HD results!

Check the processing status of your sonar logs and see them on the map! New sonar log data normally takes about a week to be integrated within SonarChart, but may sometimes take longer based on data process variables. Once ready, see the new SonarChart on plotter by updating charts via daily updates. On mobile, just tap Menu>Update All. See the latest charts on our Chart Viewer.
