• 20% increase in mapping accuracy compared to previous BlueChart generations, delivering more precise navigational details
• Depth range shading across up to 10 distinct depth intervals for rapid visual interpretation
• Contour mapping down to 1-foot resolution for precise underwater structure and seafloor topology
• Auto Guidance Technology that calculates safe routes based on user-defined depth clearance and vessel specifications
• High-resolution satellite imagery overlay synchronized with nautical charts for visual reference at unfamiliar ports and anchorages
• Shallow water shading alerts highlighting low-water zones to prevent grounding hazards
• 3-D viewing capability for enhanced situational awareness of underwater terrain and navigational obstacles

Data Insights

Garmin's BlueChart g3 Vision platform delivers measurable performance improvements for Portuguese coastal navigation. The 20% accuracy increase over prior charting versions translates to more precise depth readings, clearer seabed structure detail, and improved Auto Guidance route recommendations. Users fishing in complex offshore grounds near Lisbon and Porto benefit from the 1-foot contour resolution, which reveals subtle bathymetric features that concentrate fish populations. The 10-tiered depth shading system accelerates decision-making in variable-depth approaches, reducing navigation errors in challenging tidal zones and shallow passages typical of Portugal's Baia de Setubal and northern Costa Verde waters.

Usage Instructions

Insert the VEU479S microSD/SD card into your compatible Garmin chartplotter, fishfinder, or integrated marine GPS device. Update your Garmin device to the latest software version before first use to ensure full feature compatibility and access to all charting layers. Once loaded, activate Auto Guidance in your device settings and configure your vessel's draft and desired depth clearance. Use the depth range shading and 3-D view functions to survey bottom structure before entering unfamiliar anchorages, and reference the satellite imagery overlay for visual confirmation of coastal landmarks and port approaches.
