Garmin BlueChart® g3 HD - HXUS031R - Southwest Caribbean - microSD™/SD™

The Garmin BlueChart® g3 HD - HXUS031R - Southwest Caribbean microSD/SD card is essential navigation software for anglers and boaters operating throughout Central America's most productive fishing grounds. This high-definition electronic chart covers the northern coast from Cancun, Mexico through the Panama Canal to Barranquilla, Colombia—a region renowned for offshore sport fishing, charter operations, and coastal exploration. Whether you're targeting permit in Belize, tarpon off the Yucatan Peninsula, or deep-water game fish in the Caribbean, accurate, detailed bathymetry and navigational data keeps you safe and helps you locate structure where fish congregate.

BlueChart® g3 HD delivers Garmin's industry-leading vector chart technology with enhanced resolution, 3D bottom contours, and tide stations throughout the coverage area. The microSD/SD format ensures compatibility with a broad range of Garmin marine electronics, from traditional chartplotters to modern multifunction displays and portable handhelds. Detailed bathymetric contours reveal drop-offs, channels, and reefs critical for bottom fishing and navigating shallow flats, while improved coastal detail—including updated buoys, landmarks, and hazard data—provides confidence in unfamiliar waters. The compact card format allows quick installation and backup of multiple regional charts aboard your vessel.

Recreational and professional mariners relying on GPS-enabled navigation in the Southwest Caribbean will find this chart indispensable for route planning, anchoring site selection, and real-time positioning across Mexico's Caribbean coast, Belize, Honduras, Guatemala, El Salvador, Nicaragua, Costa Rica, Panama, and Colombia's northern waters. The microSD/SD compatibility makes it an ideal upgrade or backup chart for existing Garmin systems, and the detailed coverage of the Panama Canal—one of the world's most critical maritime passages—makes it valuable for cruising sailboats and trawlers transiting between oceans. Verify your chartplotter model accepts microSD or SD cards before purchase to ensure seamless installation.
