Garmin BlueChart® g3 HD - HXSA001R - South America East Coast - microSD™/SD™

The Garmin BlueChart g3 HD HXSA001R is a high-resolution marine chart card designed for detailed navigation along South America's east coast. This microSD/SD chart provides precise bathymetric data, coastal features, and port information from the Golfo de Paria through Tierra del Fuego, covering Trinidad and Tobago, major river systems including the Río de la Plata, Río Uruguay, and Río Paraná, plus the Falkland Islands. Built on Garmin's proven BlueChart g3 HD platform, this cartography delivers the detailed offshore and inshore navigation support serious cruisers and fishing expeditions demand in this region.

BlueChart g3 HD charts combine satellite imagery, official hydrographic survey data, and extensive coastal detail to produce navigational accuracy where it counts most. The HXSA001R card encompasses critical anchorages, reef systems, river channels, and depth contours essential for safe passage in variable tropical and temperate waters. Coverage extends to major port facilities and settlement areas, enabling reliable waypoint planning and route optimization for extended South American coastal operations. The microSD/SD format ensures compatibility with a broad range of Garmin chartplotter and GPS units, from recreational fishing boats to expedition-capable vessels.

This chart is engineered for mariners who operate regularly along the South American east coast—commercial fishermen, cruisers undertaking multi-month passages, research expeditions, and charter operations. Navigators in this region face dynamic coastal conditions, narrow river channels, and remote anchorages where standard charts lack sufficient detail. The HXSA001R addresses these challenges with high-resolution bathymetry, current information, and coastal hazard data that enable confident piloting in both familiar and unexplored waters. Whether transiting the Río de la Plata near Buenos Aires, exploring the Brazilian coastline, or operating in the Southern Ocean approaches near Tierra del Fuego, this Garmin chart provides the situational awareness required for safe and efficient passage planning.
