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.
