Satellite Overlay, offers a top-down view of inland and coastal areas.
SonarChart Shading, gives a unique perspective of underwater topography at a glance. Created from the high-definition contour data within SonarChart, our shading presents a detailed rendering of the seafloor and lake bottoms in varying shades of blue.
Especially helpful in congested ports and marinas, crisp satellite overlay can also help you find hidden features such as backwater channels that might hold fish.
Clearly see channels, drop-offs and other structures over a wide area.
Search the map for visual cues to identify fish-holding structure on inland lakes and coastal fisheries.
