MapSource BlueChart is Garmin's exclusive marine cartography and was developed to provide you with mapping flexibility and options you've never had before. This line of cartography products is designed to provide interactive viewing of detailed nautical chart data, thereby providing navigators with innovative object-oriented cartography.
These detailed electronic nautical charts look just like paper charts when displayed on your Garmin chartplotter. Features include shading between depth contours, spot soundings, navaids, port plans, wrecks, obstructions, inter-tidal zones, and more. BlueChart offers much larger coverage areas for half the price.
