Meet the GPSMAP 1243xsv 12" Combo — a high-performance chartplotter with SideVü, ClearVü and traditional CHIRP sonar, built for U.S. and Canada waters. This No Transducer bundle delivers premium navigation plus expandability for a complete marine system.
Stunning display and precise positioning
New high-resolution in-plane switching touchscreen offers improved sunlight readability and wide-angle visibility. The 10 Hz GNSS (GPS, GLONASS and Galileo) delivers precise positioning, smooth speed and course data, with a slimline, edge-to-edge glass design for a clean dash look.
Powerful sonar and charting
Integrated Ultra High-Definition SideVü and ClearVü scanning sonar with vivid color palettes helps distinguish fish from structure. Supports live sonar devices and 1 kW CHIRP traditional sonar for real-time detail. Preloaded Navionics+ coastal charts and inland mapping cover the U.S. and Canada, plus Auto Guidance+ technology (for planning purposes only and does not replace safe navigation operations) to help you get where you need to go. There’s also support for optional Navionics Vision+ premium map content.
