Details from Garmin:
8-inch Keyed Chartplotter/Sonar Combo for Cruising, Sailing or Fishing
Keyed chartplotter/sonar combo with 8-inch color SVGA display
Preloaded U.S. LakeVü HD and BlueChart® g2 coastal maps
Built-in Garmin HD-ID™ and supports CHIRP and ClearVü scanning sonar with CHIRP technology
High-sensitivity internal 10 Hz GPS/GLONASS receiver
Supports all Garmin marine radar
The GPSMAP 840xs keyed chartplotter/sonar combo has a 8-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 840xs gives you the freedom and flexibility to choose from several optional transducers, including 1 kW 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 840xs 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.
CHIRP Support
When used with a compatible CHIRP transducer (sold separately), GPSMAP 840xs 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
required).
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.
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 campgrounds.
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.
Networking
The GPSMAP 840xs 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.
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.
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 Guidance² technology instantly searches through relevant charts to create a 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 Ultra cartography¹.
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.
Panoptix™ Down Transducer
With 1 Panoptix Down transducer, you get 3 remarkable views, allowing you to actually see fish and bait swimming around under your boat – in real time. You can even see fish in the water column in 3-D, from the bottom to the surface. You can be stationary yet still see things in 3-D below your boat.
LIVEVÜ DOWN
Shows real-time moving sonar images below the boat. This screen shows bait drop echo trail movement in purple with sonar history data at left.
REALVÜ 3-D DOWN
