Garmin GPSMAP 1243 12" Chartplotter GN+

GPSMAP® 1243 Chartplotter GN+

You’re a boater who wants premium features, maps, and charts for your connected helm. This crisp 12" high-resolution chartplotter makes that wish come true.

Get a sharper view from your connected helm with the GPSMAP® 1243 chartplotter. It's high-resolution 12” in-plane switching touchscreen and ultra-sleek design seamlessly integrate into your Garmin marine system, putting full control at your fingertips.

Preloaded Garmin Navionics+™ coastal charts and inland mapping feature Auto Guidance+™ technology (Auto Guidance+ is for planning purposes only and does not replace safe navigation operations) for helping you get where you need to go. Plus, there’s support for optional Garmin Navionics Vision+™ premium map content.

Easily build your marine system — from compatible sonar and autopilots to compatible radar, cameras and multimedia — by using HTML 5.0, NMEA 2000® and NMEA 0183 networking, J1939 for engines, and the Garmin Marine Network.

Add FrontVü™ forward-looking sonar (sold separately). (The ability to effectively avoid forward collisions with FrontVü sonar decreases as speed rises above 8 knots[HT1] ) which can help in avoiding underwater obstructions ahead. Or pair your plotter with your other compatible Garmin devices, such as quatix® smartwatches, wind transducers, wireless remote controls, and more.

Features:

High-resolution in-plane switching touchscreen display offers improved sunlight readability and wide-angle visibility over previous-generation 12” units

Fast and responsive, this robust GPSMAP® system references 10 Hz GNSS (GPS, GLONASS, and Galileo) for accurate positioning and smooth speed as well as COG data

Slimline display borders, edge-to-edge glass, and reduced unit footprint make for easy retrofit in a wider range of dash configurations
