GPSMAP® 1243xsv with GMR™ 18 HD3 Radome

The GPSMAP® 1243xsv with GMR™ 18 HD3 Radome is a cutting-edge 12" chartplotter and radar combination that seamlessly integrates into your Garmin marine system. Its sleek design, powerful processing, and upgraded IPS display make it a top choice for boaters.

One of the standout features of this chartplotter is its ultra-high-definition scanning sonar. With built-in sidevü and clearvü™ scanning sonars, you can easily distinguish fish from structure with vivid, high-contrast color palettes. Additionally, the GPSMAP® X3 series supports 1 KW chirp traditional sonar capabilities.

For even more advanced sonar capabilities, you can pair the GPSMAP® 1243xsv with panoptix or livescope™ easy-to-interpret live sonar (transducer required, sold separately). This allows you to see all around your boat in real-time, providing a comprehensive view of your surroundings.

The GPSMAP® 943xsv also boasts improved processing power and a slimline design with edge-to-edge glass, making it easy to retrofit in a wider range of dash configurations. The display optics have been enhanced as well, offering improved sunlight readability and visibility from any angle, thanks to 50% more pixels than previous-generation GPSMAP devices.

When it comes to mapping, the GPSMAP® 1243xsv doesn't disappoint. It comes preloaded with Garmin Navionics+ integrated coastal and inland mapping, providing unparalleled coverage and detail. This includes Auto Guidance+™ technology and a 1-year subscription for downloadable daily updates and more on select chartplotters.

If you're looking to enhance your chartplotter even further, you have the option to upgrade to Garmin Navionics Vision+™ premium chart subscription. This includes downloadable high-resolution relief shading, satellite imagery, sonar imagery, and more, giving your chartplotter a fresh look and feel.
