Garmin’s new GPSMAP 8400 series of powerful all-in-one multi-function displays (MFDs) offers boaters much more than the highest screen resolution on the water.

With a sleek glass helm look, these large-format MFDs are available in 17”, 22” and 24” displays that feature full HD in-plane switching (IPS) screens with multi-touch control. Incorporating new and improved processors, they provide increased performance, enhanced video processing, and the fastest chart drawing offered in a Garmin MFD.

These sunlight-readable MFDs feature an anti-glare IPS LCD display that provides consistent, accurate colours that can be seen from all viewing angles, which is an industry first for this class. The GPSMAP 8417and 8424 offer a WUXGA 1920×1200 display, and the GPSMAP 8422 has an FHD 1920×1080 display. The maximum glass design can be flush or flat-mounted, and enables edge-to-edge installation of multiple displays.

The processing power in the GPSMAP 8400 series is the highest offered in a Garmin MFD. All added sensors like radar, sonar, Panoptix, and multimedia benefit from this increased performance and provide a premium user experience across the entire network.

With new One Touch presets for sonar, charts, radar, cameras, media, and digital switching, the GPSMAP 8400 series takes Garmin’s already intuitive user interface to another level – and it can be independent or incorporated into SmartMode station controls. Users can configure and customise their entire system for activities from cruising, fishing, anchoring and docking with just one touch.

Boaters can view videos in full or spilt-screen from a variety of media devices on the MFD’s display using the HDMI video input, or they can mirror the chartplotter screen on a TV or monitor using the HDMI output port found on these new devices. HDMI video is inherently shared across the Garmin Marine Network and can be viewed on multiple displays. Users can even play digital audio from HDMI input through the boat’s stereo.

The all-in-one compact design of the GPSMAP 8400 series eliminates the need for black boxes, monitors, and external Wi-Fi antennas. They also feature built-in Wi-Fi and ANT that allow the unit to connect to a new Garmin quatix 3 marine GPS smartwatch, Nautix In-View Display, VIRB action cameras, RF wireless remote control, smartphones, and tablets. The GPSMAP 8400 series screen can even be spilt to show up to six different features simultaneously, including HDMI video input.

The MFDs feature four wired-Ethernet ports, composite video input, and are fully-networkable across the Garmin Marine Network, NMEA 2000, and FUSION-Link. Users will also benefit from enhanced video processing with up to four IP camera streams and simultaneous Garmin Helm support.

Support for J1939 is also available, providing engine and generator data with configurable templates for instrumentation.





Garmin’s new GMR Fantom 18 and GMR Fantom 24 solid-state pulse compression radomes offer MotionScope Doppler technology and 40W of power – the highest in the industry for its kind.

Available in an 18” or 24” footprint, they bring Garmin’s award-winning Fantom technology to a smaller size and lower price point, making them an attractive option for boats where open-array radar isn’t an option.

Revolutionising the way boaters use radar, Garmin Fantom technology uses Doppler processing to detect moving targets in real time, helping users avoid potential collisions, find birds, and track weather. Upon detection, MotionScope highlights moving targets on the radar display with an easy-to-see colour so users can navigate around other boats or severe weather. Auto Bird Gain also allows boaters to easily locate birds at the water’s surface, indicating the presence of game fish.

When the Echo Trails setting is turned on, a fading ‘trail’ on the screen can help easily identify the direction of the moving targets and potential collision threats. The trails shown are also corrected for the boat’s rotation when an autopilot or heading sensor is connected to the Garmin Marine Network.

With its pulse compression technology, the Fantom 18 and Fantom 24 provide high resolution while maximising energy to enhance target detection. Pulse expansion can then maximise target size to help differentiate real targets from noise. The Fantom 18 features a 5.2-degree beam width, while the Fantom 24offers a narrower 3.7-degree width that paints a very precise, high-resolution image.

Both Fantom radomes offer excellent range performance from 6m to 48nm, without compromise in ruggedness or reliability. Thanks to the dual range feature, boaters have the ability to see both close- and long-range simultaneously, with an overlay on a chart for one or both ranges. This eliminates the need to toggle between views, and allows the skipper to keep a close eye on immediate surroundings and those on the horizon to ensure weather patterns, land and structure can always be observed.

The Fantom 18 and Fantom 24 feature low power consumption (less than 25W) and instant turn-on, so no warm-up time is needed and users can start tracking targets instantly. With dual radar support, Fantom radomes can also be used with a Fantom open-array, a GMR xHD2 open array, or a GMR xHD dome radarto provide radar redundancy and more flexibility to view different data on independent display units.

Dynamic Auto Gain and Dynamic Sea Filter continually adjust to surroundings, water and weather conditions to provide optimal performance and reduce excess noise and clutter, while MARPA settings enable the tracking of 10 targets simultaneously.

The Fantom 18 and Fantom 24 are compatible with the new GPSMAP 752/952 and 1022/1222 series, as well as the GPSMAP 74008000 and 8400 series.




With its solid-state 9-axis Attitude Heading Reference System (AHRS), the GHP Reactor™ autopilot series holds your course even when your boat is pitching and rolling in rough water. Offers flexible installation options and requires a minimum amount of commissioning and calibration. The result is that everyone onboard enjoys a comfortable ride while heading error, course deviation, rudder movement and power consumption are minimised.

  • Solid-state 9-axis Attitude Heading Reference System (AHRS)
  • Minimises heading error, course deviation, rudder movement and power consumption while providing a comfortable ride
  • Minimal commissioning and calibration
  • Supports heading hold, wind hold, step turns and tack/jibe modes

With a complete package designed for powerboats and sailing boats, Garmin brings an advanced marine technology to the boating public that was once only available for commercial boats. The Reactor 40 autopilot series is simply the most responsive autopilot system we have ever offered.

Reactor 40 autopilots are very versatile. Both powerboat and sailing features are available in all corepacks, including heading hold, wind hold, tack/jibe, step turns and more; simply pick the autopilot that’s compatible with your existing steering system. If you don’t see a compatible Reactor 40, you’ll find the Reactor 40 mechanical/retrofit/solenoid is compatible with a wide variety of steering systems, whether hydraulic, cable drive, mechanical and solenoid. Just pair GRF™ 10 with your drive system already on board.

The Reactor 40 mechanical/retrofit/solenoid autopilot corepack is ideal for sailboats and powerboats with direct or cable-actuated steering systems. This Reactor 40 below-deck autopilot system gives captains that “extra set of hands” they need so you can safely attend to your sails, lines, winches and radios, without worry. With its solid-state 9-axis AHRS, Reactor 40 mounts anywhere, in any orientation and requires minimal commissioning.

VHF Communications


Garmin’s powerful VHF 110i and VHF 210i AIS marine radios have been designed for both OEM and aftermarket applications.

Featuring an updated industrial design and sleek aesthetics, the VHF radios were built to complement the stylish design of Garmin’s latest GPSMAP chartplotters and multi-function displays (MFDs), and offer full integration with Garmin systems.

The VHF 110i is Garmin’s entry-level radio, offering 25W of transmit power and Class D Digital Selective Calling (DSC) compatibility via NMEA 2000. In addition to dedicated buttons and knobs for ease of use, the VHF 110i features three soft keys that allow boaters to intuitively see and select the information they want, while eliminating the clutter they don’t. The VHF 110i also features Position Tracking, which allows boaters to locate and keep tabs on up to three boats that also use a Garmin system.

For boaters wanting to take advantage of the Automatic Identification System (AIS), the VHF 210i AISincorporates all of the features mentioned above and adds a built-in AIS receiver for improved situational awareness and greater confidence on open water. With 25W of transmit power, the VHF 210i AIS also comes standard with a two-way hailer system that can be connected to a hailer horn or external speaker on the deck or tower for onboard communication. Like the VHF 110i, the VHF 210i AIS provides standard DSC functionality, including distress calling and direct calling with user-programmed Maritime Mobile Service Identity (MMSI).

You can even see your lure as you retrieve it. And your boat doesn’t need to be moving. These images are so clear and precise that with a little practice, you might be able to distinguish between species of fish!

  • See highly detailed, easy-to-interpret live scanning sonar images of structure, bait and fish swimming below and around your boat in real time, even when your boat is stationary
  • Easily adjust the transducer to fit your fishing techniques; point forward to see around your boat, or point down to see directly below your boat
  • See incredibly sharp real-time scanning sonar images up to 200’ down and away
  • Attitude Heading Reference System (AHRS) stabilizes sonar view on chartplotter screen, even in rough conditions
  • Simple plug-and-play Garmin Marine Network connector makes it easy to install and seamlessly integrate with your compatible Garmin chartplotter


Garmin’s new all-in-one transducers have been specifically designed for the latest range of echoMAP combos and GPSMAP multifunction displays.

Eliminating the need to install multiple transducers, the new all-in-one transducers deliver ClearVü™ and SideVü™ scanning sonar, along with traditional/CHIRP sonar (depending on the model), within the one unit to further simplify the installation process.

Complementing the newest echoMAP units (which feature built-in ClearVü and/or SideVü scanning sonar, model dependant), the GT21/40/41 series of transducers come with an in-hull or transom-mount option.

The GT21 series provides ClearVü scanning sonar with industry-first 260/455kHZ and Garmin’s traditional HD-ID sonar at 50/200kHz, offering an optimised experience for rough conditions and depth performance.

For a clearer image in shallower depths, the transom-mounted all-in-one GT40 offers both ClearVü and SideVü scanning sonar at 455/800kHz, while also delivering traditional HD-ID sonar at 77/200kHz.

The GT41 series provides an all-in-one option optimised for saltwater fishing by offering ClearVü and SideVü scanning sonar at 260/455kHz and traditional HD-ID sonar at 50/200kHz.

Stepping up yet another level, the new GT50/51 transducers have been developed for Garmin’s GPSMAP series. Available as both thru-hull and transom-mount versions, the GT50/51 all-in-one transducers offer CHIRP ClearVü and CHIRP SideVü scanning sonar as well as Garmin CHIRP sonar.

For shallow water, the GT50 runs CHIRP ClearVü and CHIRP SideVü at 455/800kHz and 300W traditional CHIRP at 80/160kHz. For deeper water and potentially rougher conditions, the GT51 scans 260/455kHz for CHIRP ClearVü and CHIRP SideVü, and 600W 80/160kHz for CHIRP sonar.
