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

Garmin GSD 21 Sounder
(click here for more info)
The GSD 21 is a remote, black-box sounder that transmits 500 watts at 50/200kHz. It’s designed specifically for use with the GPSMAP® 2006 and GPSMAP 2010 series units (including color versions) to provide SONAR capabilities to these units |
Garmin GSD 22 Sounder
click HERE for more info
The GSD 22 is a powerful remote sounder that plugs directly into the Garmin Marine Network for use with our network chartplotters — or into the new Garmin CANet™ for use with the new series chartplotters. Ultrascroll™ technology keeps the display scrolling at live-action speeds, while the unit’s digital design and up to 2 kW of transmit power (depending on transducer used) provide extraordinary target definition and deep water performance. Transmit power and receiver gain automatically adjust to produce excellent shallow water performance as well. The GSD 22 is dual frequency (200/50 kHz) and works with everything from a standard 500 W transom mount transducer to heavy-duty 2 kW thru-hull or in-hull transducers. Reaches depths to 5,000 feet. |
