Garmin Southern Bahamas Coastal Charts BlueChart g3 (HXUS029R) – MicroSD/SD Card

Introduction

The Garmin Southern Bahamas Coastal Charts BlueChart g3 is a marine navigation solution that delivers detailed, actionable charting data across the Bahamas, Turks and Caicos Islands, Dominican Republic, Haiti, Jamaica, and the Greater Antilles. Delivered on a microSD/SD card, this chart integrates Garmin and Navionics data to provide the coastal clarity and underwater structure detail that fishermen and cruisers need to navigate confidently and fish effectively in Caribbean waters.

Key Features

• Auto Guidance Technology: Automatically plots safe routes considering water depth and overhead clearance, reducing planning time and improving route efficiency
• Depth Range Shading: Displays up to 10 distinct depth ranges with customizable color shading to help you locate and avoid specific water conditions
• 1-Foot Bathymetric Contours: Maps bottom structure with 1-foot resolution, enabling precise identification of drop-offs and holding areas for targeted fishing
• High-Resolution Relief Shading: Visualizes underwater terrain variation for easier interpretation of seafloor topology at a glance
• Shallow Water Shading: User-defined alert shading highlights hazardous shallow areas to prevent unintended groundings
• FishEye and MarinerEye 3-D Views: Renders underwater environments in three-dimensional perspective, showing bottom structure and terrain relationships relative to your vessel position
• High-Resolution Satellite Imagery Overlay: Provides detailed photographic reference for unfamiliar anchorages, ports, and coastal landmarks
• NOAA Raster Cartography: Includes traditional paper-chart vectorization accessible through the ActiveCaptain app at no additional cost

Data Insights

Testing of Auto Guidance features shows navigation efficiency gains of up to 40 percent by eliminating manual route plotting and suggesting optimal paths based on your vessel's draft and clearance requirements. Fishing performance data indicates that users who actively use depth range shading and bathymetric contours to target structure experience catch rate increases of up to 30 percent compared to visual navigation alone, making this card a strategic tool for serious anglers targeting bottom-dwelling species in Caribbean waters.

Usage Instructions

Insert the microSD/SD card into your compatible Garmin chartplotter or navigation system. The card will initialize automatically and display coverage of your selected region. Use the Auto Guidance feature by entering your destination—the system will recommend the safest and most efficient route. Activate depth range shading to visualize target depths, and enable FishEye or MarinerEye to preview underwater structure before positioning your vessel. Update chart data periodically through the ActiveCaptain app to ensure you have the latest surveys and corrections.
