The GPSMAP 546s is a compact chartplotter that features a high-resolution, super-bright 5" (12.7 cm) VGA color display along with an improved high-speed digital design for increased map drawing and panning speeds. It’s ready to go with an easy-to-use interface and a built-in, satellite-enhanced basemap preloaded with all U.S. coastal areas, including Alaska and Hawaii as well as detailed charts for the Bahamas. The GPSMAP 546s also accepts BlueChart® g2 Vision® cards (sold separately) for added features and functionality such as high-resolution satellite imagery, 3-D views and Auto Guidance technology.
Explore the Seas
The GPSMAP 546s comes ready to go with preloaded U.S. coastal area map data. For areas outside the U.S., the GPSMAP 546s has a worldwide basemap with satellite images in place of more traditional maps. The GPSMAP 546s also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the GPSMAP 546s can receive U.S. graphical weather data via optional GXM™ 51 satellite receiver/antenna (sold separately). And with an SD™ card slot, it’s easy to add additional maps without connecting to a computer.
Get Sonar
The GPSMAP 546s comes with a powerful dual-frequency transducer that clearly illustrates depth contours, fish targets and structures whether you’re fishing in freshwater or off the coast. The GPSMAP 546s also is NMEA 2000®-certified for easy connectivity with sensors, instruments and future marine offerings.
Add Extras with BlueChart g2 Vision
With the optional BlueChart g2 Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.
- MarinerEye view and FishEye view provide you a 3-D perspective of map information, both above and below the waterline.
- High-resolution satellite images and aerial photographs help you orient yourself in unfamiliar areas.
- Auto Guidance technology searches through all relevant charts to create a route you can actually follow — one that avoids obstacles, shallow water, buoys and other obstructions.
