 Garmin GPSMAP 521 / GPSMAP 521S
The Garmin 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, 3D views and Auto Guidance technology.
VERY IMPORTANT: "S" models have built in sounders and can connect directly to a transducer. Other models will need an external sounder (GSD 21 or GSD 22) AND a transducer compatible with the GSD unit.

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 Sonar
Where applicable, the sounder version, GPSMAP 521s, 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 521 and GPSMAP 521s are also 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.
- 3D Mariner’s and Fish Eye view provides you with 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

NMEA 2000® Transducer Adapter Kit
010-11525-00
With the NMEA 2000 Transducer Adapter Kit, you can save both time and money by upgrading your depth transducer to NMEA 2000 without hauling your boat out of the water. Use our kit to adapt depth information, which is currently provided by an installed Airmar® P19 (or compatible) 200 kHz transducer on a boat, to the NMEA 2000 network. Once adapted, you can observe depth information on compatible Garmin display devices that are connected to their NMEA 2000 network. |
GDL 40 On-Demand Cellular Marine Weather Receiver
Part #: 010-00849-10
The GDL 40 receives data via cellular networks rather than satellites, it can provide weather information at a fraction of the cost. There are no monthly subscription fees, only a small annual activation fee - the first of which is included in the price of the device.
Once you've activated your GDL 40, you can then purchase day passes from the device for just $4.99. A day pass provides you with 24 hours of continuous weather data.
Plug the system into any compatible Garmin chartplotter display and begin accessing on-demand radar, wind speed/direction, surface temperature, warnings, forecasts and much more. Because the system requires you to be within range of a cellular tower, it's an ideal solution for boaters that remain near shore.
In addition to conventional pole or flush surface mounting, the GDL 40 can also be attached to the underside of many fiberglass or wooden decks |
