The GPSMAP chartplotter/sonar combo has a 10-inch color SVGA display and comes
with preloaded U.S. LakeVü HD and BlueChart g2 coastal maps. HD-ID 1 kW sonar,
CHIRP and ClearVü with CHIRP sonar technology are built-in, allowing you the
flexibility to choose from several optional transducers. It also provides
media integration and autopilot compatibility, radar support, and NMEA 2000®
and wireless connectivity.
Extreme Sonar Capabilities
The built-in sonar capabilities of the GPSMAP gives you the freedom and
flexibility to choose from several optional transducers, including
traditional, CHIRP and all-in-one HD-ID/ClearVü scanning sonar with CHIRP
technology. Add a GCV™ 10 scanning sonar module for both ClearVü and
SideVü scanning sonar with CHIRP technology (sold separately).
Allow networked combos to share their internal sonar with any other device
on the network. GPSMAP 820xs also gives you the flexibility to choose what
information is overlaid on the sonar screen. For example, time of day or GPS
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
When used with a compatible CHIRP transducer (sold separately), GPSMAP
displays crystal-clear sonar images detailing fishing hot spots, ship wreckage
or a diving location. With Garmin CHIRP technology, you get remarkable target
separation and resolution at extraordinary depths, and can dial into specific
frequencies to target certain species of sport fish. Bottom contours are more
visible, even at speed, 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.
Dynamic Sea Temperature
Set a range for sea temperatures, and it dynamically adjusts to display a
color range that can be used to target certain types of fish (Optional GXM™ 52
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.
Preloaded LakeVü HD Maps
These highly detailed freshwater maps include 17,000+ U.S.
lakes, rivers and reservoirs. Included in those are more than 13,000 HD lakes
with 1-foot contours shoreline to shoreline; excellent detail of underwater
features plus Shallow Water Shading that allows you to designate a minimum
depth; interstates, highways, general roads and bridges; designated fishing
areas; and points of interest, such as docks, boat ramps, marinas and
Super-fast 10 Hz GPS/GLONASS
High-sensitivity internal 10 Hz GPS/GLONASS provides position and heading
updates 10 times per second. It displays fluid on-screen location and proves
to be incredibly accurate when marking waypoints and navigating.
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
Garmin autopilot, engine data, SiriusXM Weather radar and more.
The GPSMAP offers select networking capabilities that allow you to
share features with other compatible GPSMAP units, such as radar, GCV 10
ClearVü and SideVü scanning sonar, supplemental maps, and user data, including
waypoints, routes and tracks. User data entered into 1 chartplotter can be
automatically synced with other chartplotters in a network.
Special Sailing Features
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.
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.
FUSION-Link Entertainment System
Enjoy the ability to control all compatible FUSION-Link-enabled audio
systems directly from your compatible chartplotter display.
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 chartplotter. Even if
you don’t have a Garmin chartplotter, you can still take advantage of the
tremendous features of BlueChart on your Apple device.
Enhanced Auto Guidance
Just enter the location where you want to go and patented Garmin Auto
Guidance technology instantly searches through relevant charts to create a
safe virtual pathway on the display that helps you avoid low bridges, shallow
water and other charted obstructions en route.
Better still, with enhanced Version 2.0, you now have access to even more
features and capabilities. You’re able to adjust the calculated Auto Guidance
pathway by inserting “via” points at interim stops or landmarks along your
desired route. You can easily review hazard points along your calculated path.
And you can even engage your compatible Garmin autopilot to follow the Auto
Guidance route, automatically. Other 2.0 enhancements give you the ability to
calculate arrival times at any point on your route (great for timing arrivals
to correspond with bridge openings and other time-critical events). Better
still, you can now save your plotted Auto Guidance paths for future navigation
by backing them up on an SD™ card with your BlueChart® g2 Vision® or Lake Vü™ HD
GPX Waypoints Transfer
If you have waypoints, tracks or frequently used routes stored on another
manufacturer’s GPS product – or on a Garmin handheld device – now it’s easier
than ever to transfer those items to your new Garmin chartplotter, via
industry-standard GPX software formatting. GPX is an open standard format for
GPS data exchange across platforms and applications. With this easy-to-use
interface technology, Garmin has taken “no waypoint left behind” to a whole
new level of trade-up convenience.
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™
