The Garmin GPSMAP 1243xsv Chartplotter gives anglers full control at the helm with a responsive 12-inch display, advanced networking, and integrated sonar tools that help you break down structure for walleye, follow bait schools for striped bass, and track offshore contours for tuna. Preloaded Garmin Navionics+ charts on select models support confident navigation across inland lakes and coastal waters, while built-in sonar capabilities on select models (transducer required) reveal what sits directly below your boat. Advanced network connectivity lets you expand your marine system with radar, autopilot, multiple displays, and more, and engine integration supports a wide range of compatible power systems for consolidated data at the helm. Digital switching and OneHelm integrations connect compatible third-party devices into a unified control interface, and remote access features allow you to manage and monitor your marine experience from nearly anywhere.
