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 DownVü 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/DownVü scanning sonar with CHIRP technology. Add a GCV™ 10 scanning sonar module for both DownVü 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.

Includes Inland and Coastal Mapping

The GPSMAP 840xs comes preloaded with both BlueChart g2 coastal maps and LakeVü HD, which features 17,000 U.S. lakes, of which more than 5,700 HD lakes have 1-foot contours shoreline to shoreline. It's also compatible with optional mapping, LakeVü HD Ultra with MaxDef Lakes and BlueChart g2 Vision.

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 DownVü 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 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 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

Scans the area below the boat from front to back and side to side. This screen shows a school of fish sitting against the back side of vertical face, on Pport side of boat 35 feet deep.

REALVÜ 3-D HISTORICAL

Scrolls through the data as the boat moves to show the history of entire water columns – from the bottom to the surface and all of the fish in between. This screen shows the boat passing over a stream channel with a school of fish between 30 to 40 feet.

Panoptix Forward Transducer

One Panoptix Forward transducer provides 2 impressive views, even while your boat is stationary. It shows the bottom plus fish and bait swimming in the water column in front of your boat – in real time. You can even see your lure as you reel it in. You can also get 3-D views of fish and structure in front of your boat.

LIVEVÜ FORWARD

Updates are provided with a single ping, providing real-time moving images of what’s in the water. This screen shows a large target (a diver) approaching the boat.

REALVÜ 3-D FORWARD

Digitally scans the area in front of the boat, creating a forward-looking 3-D view of the bottom, structure and fish. This screen shows fish targets at 10 feet and drawing bottom depth of 20 feet.
