Garmin GPSMAP 1643xsv Chartplotter with SideVü, ClearVü, CHIRP Sonar and Mapping

The Garmin GPSMAP 1643xsv is a premium 16-inch marine chartplotter combining a Full HD IPS touchscreen, advanced built-in sonar and Garmin Navionics+ mapping. Designed for anglers who want a large, detailed display for navigation and fish finding, it integrates traditional CHIRP sonar with Ultra High-Definition ClearVü and SideVü scanning sonar.

With 1 kW traditional CHIRP sonar capability, built-in ClearVü and SideVü, and support for Garmin LiveScope and Panoptix systems, the GPSMAP 1643xsv delivers detailed underwater imaging and extensive connectivity for advanced fishing boat installations.

WHY THE GARMIN GPSMAP 1643xsv WORKS

• Large 16-Inch Full HD IPS Display: The 15.6-inch diagonal touchscreen features 1920 x 1080 resolution, wide viewing angles and excellent sunlight readability. Its large viewing area is ideal for displaying navigation charts and multiple sonar views.
• Advanced Built-In Sonar: Traditional CHIRP sonar helps locate fish and identify bottom composition, while Ultra High-Definition ClearVü and SideVü provide detailed scanning images below and beside the boat.
• Extensive Marine Connectivity: Two Garmin Marine Network ports, NMEA 2000, NMEA 0183 and support for compatible LiveScope, Panoptix, radar and other marine systems make it suitable for sophisticated multi-device installations.

The GPSMAP 1643xsv is particularly well suited for bass, walleye, musky and multispecies fishing where a large screen makes it easier to monitor detailed sonar images, underwater structure and navigation information simultaneously.
