Garmin BlueChart® g3 HD - HXPC414S - Mackay - Twofold Bay - microSD™/SD™

The Garmin BlueChart® g3 HD - HXPC414S microSD/SD card delivers high-definition electronic chart coverage for the Eastern coast of Australia, spanning from Mackay to Twofold Bay. Designed for serious mariners, coastal fishermen, and recreational boaters, this chart card provides the detailed bathymetric data and navigational aids required for confident passage through complex Australian waters, whether you're targeting pelagic species offshore or navigating narrow harbor approaches.

BlueChart g3 HD maps are derived from official hydrographic charts and private data sources, integrating depth contours, spot soundings, tidal information, and current data into a single, high-resolution cartographic layer. Coverage extends through all major fishing and cruising grounds including Hervey Bay, Fraser Island, Brisbane, Port Stephens, and Sydney. The HD resolution enables identification of fine bottom features, reef structures, and depth breaks that directly impact fish behavior and navigation safety. The microSD/SD format ensures compatibility with a broad range of Garmin marine GPS units and multifunction displays manufactured over the past decade, from compact chartplotters aboard center consoles to full-featured glass cockpits on larger vessels.

This chart card is essential for anglers working the productive grounds between Mackay and the NSW south coast—regions known for barramundi, trevally, Spanish mackerel, and deep-water snapper. Cruising sailors value the precise coastline detail and anchorage positioning. The small physical footprint (6 x 1 x 8 inches) makes it portable for updating multiple vessels or maintaining backups. Installation is straightforward: insert the card into a compatible Garmin chartplotter, and the g3 HD data loads automatically with no software configuration required.
