GPSMAP 521

The GPSMAP 521 is a compact chartplotter that features an ultra-bright 5” QVGA color display along with an improved high-speed digital design for increased map drawing and panning speeds. It’s ready to go with a built-in, satellite-enhanced worldwide basemap and an easy-to-use interface designed to help you navigate the open waters with ease. The GPSMAP 521 also accepts BlueChart® g2 Vision cards for added features and functionality such as high-resolution satellite imagery, 3-D views and Auto Guidance technology.

View Satellite-enhanced Worldwide Basemap

The GPSMAP 521 basemap contains worldwide satellite images in place of traditional maps. The GPSMAP 521 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the GPSMAP 521 can receive U.S. graphical weather data via optional GXM 51 satellite receiver/antenna. And with an SD card slot, it’s easy to add additional maps without connecting to a computer.

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-dimensional 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.
