Garmin Fish Finders & Chartplotters

An Amazing Combo with a 7-inch Touchscreen Display

• 7-inch WVGA touchscreen display with pinch-to-zoom
• HD-ID™ sonar
• 10 Hz GPS/GLONASS receiver
• NMEA® 2000 and wireless connectivity
• Worldwide basemap

GPSMAP 721xs combination chartplotter/sounder allows for easy visibility, day or night. Whether it is flat-, flush- or bale-mounted, it will be the focal point of your helm. It has media integration and autopilot compatibility, radar support, and NMEA 2000 and wireless connectivity. It includes our hallmark user-friendly interface as well as a worldwide basemap.

Super-fast 10 Hz GPS/GLONASS

With the integration of a 10 Hz GPS/GLONASS receiver, the 721xs refreshes position and heading up to 10 times per second. It displays constant and fluid on-screen location and proves to be incredibly accurate when marking waypoints and navigating.

Advanced Sonar Support

Built-in support for a wide selection of Garmin transducers, including 50/200 kHz, 77/200 kHz, DownVü scanning sonar and CHIRP. In addition, it will also support Minn Kota® and MotorGuide® trolling motor transducers.

Allow networked combos to share their internal sonar with any other device on the network. GPSMAP 721xs also gives you the flexibility to choose what information is overlaid on the sonar screen. For example, time of day or GPS speed.

It also includes sonar-recording capability that coordinates the timing of the sonar return with your boat's position and saves digital information for playback on a computer using HomePort™ planning software

Add the Clearest Scanning Images on the Water

Add the optional GCV™ 10 black box sonar to enjoy Garmin DownVü and SideVü™ scanning sonar with the clearest scanning sonar images on the water.

Advantages of CHIRP Technology

When used with a compatible CHIRP transducer (sold separately), GPSMAP 721xs displays crystal-clear sonar images to help find the next hidden fishing spot, ship wreckage or diving location. Garmin CHIRP sonar allows you to see target separation and resolution at extraordinary depths, and dial into specific frequencies to target certain species of sport fish. Bottom contours are more visible, and signal noise can be suppressed at greater depths to provide a more timely interpretation of what’s below for safer navigation and better fishing.

NMEA 2000 Support

This combo allows you to add more capabilities to your boat. It provides NMEA 2000 support so you can see valuable information on your screen for autopilot, engine data, SiriusXM weather and more.

Radar Support

Add your choice of marine radar, either open array or our new xHD dome radar that pair ease of use with advanced open array features.

Networking

The GPSMAP 721xs offers select networking capabilities that allow you to share features with other compatible GPSMAP units such as supplemental maps, and user data including waypoints, routes and tracks. User data can be automatically synced with other chartplotters in the network.

Special Features for Sailing

Supported sailing features include laylines, enhanced wind rose, heading and course-over-ground lines, true wind data fields and tide/current/time slider. Gauge displays are designed to provide important need-to-know information at a glance, including true and apparent wind angle, set and drift, true or apparent wind speed, horizontal or vertical graphs, and a data bar with customizable data fields.

GND™ 10 Black Box Interface

The GND 10 black box interface seamlessly integrates Nexus instruments and sensors with the Garmin family. It converts data between the Nexus network and NMEA 2000 to provide trouble-free compatibility between Nexus and Garmin products, including gWind™ and gWind Race wind transducers.

Compatible with gWind Transducers

Garmin gWind, gWind Wireless and gWind Race transducers feature twin-fin technology with 3-bladed propeller. Connect to the NMEA 2000 and compatible Garmin chartplotters via the GND 10 black box bridge.

View and Control Your Device From a Smartphone or Tablet

Garmin Helm™ allows you to view and control your compatible Garmin chartplotter from an iPhone® or iPad® or phone, or phone or tablet using Android™ — while providing enhanced situational awareness for the mariner. Easily switch between portrait and landscape mode to accommodate mounting preferences. Using your iPhone or iPad, you can even record a movie of your chartplotter screen to share with friends and family. Download from the App Store™ or Google Play™ today.

Get Your Apple® Device Onboard with BlueChart® Mobile

With BlueChart Mobile, a free app downloaded from the App Store™, you can plan marine routes on your iPad® or iPhone® then wirelessly transfer them to your boat’s compatible networked Garmin chartplotter¹. Even if you don’t have a Garmin chartplotter, you can still take advantage of the tremendous features of BlueChart on your Apple device.

Create your own HD maps

Quickdraw Contours is a free, easy-to-use software feature already installed on your compatible Garmin combo. It instantly creates your own personalized HD fishing maps with 1-foot contours. Tailor them to fit your needs. They are your maps — you own them. Keep the data to yourself, or share it with the Quickdraw Community on Garmin Connect™. There’s no special surveying expertise required. You just fish while it creates maps. You don’t have to wait around or send your files away like other mapping software requires — your results appear instantly. Use with any of the following sonar transducers:  Garmin Panoptix™, HD-ID™ traditional, CHIRP-enabled, Garmin DownVü™ or NMEA 2000^®-compatible depth. Have more than 1 sonar device installed onboard? Quickdraw Contours automatically selects the most capable sonar device to provide the very best results for you!

Multiple Depth Range Shading

Designate up to 10 different depth ranges each with its own color. Makes it easier to view target depths at a glance.

Sharpen your radar picture with high definition performance. The GMR 18 HD radar offers a whole new level of radar scanning capability.

Get Powerful Performance

The GMR 18 HD features high-powered Digital Signal Processing, providing sharper radar imagery and improved target separation.

This 18" (45.7 cm), 4 kW high definition radar has a 36 nm range, bringing radar images into even clearer focus. With automatic pulse optimization technology, the radar matches pulse widths and repetition rates with the nautical mile range that is selected. Combine that with the antenna’s 5 degree beamwidth, and you’re looking at the best weather penetration and target definition in its class.

To help you avoid traffic on the water, the GMR 18 HD provides MARPA target tracking when combined with a multi-function display and an optional heading sensor. MARPA tracking allows you to track the bearing, course, speed and predicted closest approach of up to 10 targets. In addition, like all Garmin radars, the GMR 18 HD has self-contained signal processing, which provides you with a more precise, easy to read signature.

Connect to the Garmin Marine Network

The GMR 18 HD transmits data over the Garmin Marine Network, a 100 MB plug-and-play proprietary network that gives you the ability to expand your boat’s system as needed. Once connected to the network, you can use any network-compatible Garmin chartplotter as your radar screen. And as an aid to locational awareness, you can overlay the GMR 18 HD radar image on the chartplotter's map page. You also can split the on-screen display so you can view the map and the standard radar page simultaneously.
