Furuno FM4850 Black Box VHF Radio w/GPS, AIS, DSC & Loudhailer Product Description
Why the Furuno FM4850 Stands Out on the Water
Imagine navigating choppy seas at dusk, fog rolling in thick, and needing to hail a nearby vessel without shouting into the wind. Or picture the thrill of a big strike on your lines during a deep-sea trip, wanting to alert the crew instantly without leaving the rod. The Furuno FM4850 black box VHF radio transforms these scenarios from stressful to seamless, packing five essential tools into one rugged unit: VHF communications, Class-D DSC for emergency calls, AIS receiver for spotting traffic, GPS positioning, and a powerful 30-watt loudhailer with intercom smarts.
Unlike bulky traditional VHF setups that clutter your helm, this compact black box slips neatly behind panels, perfect for space-strapped center consoles or sleek sportfishers. Its handset mimics the sleek design of Furuno's NavNet and NavPilot gear, blending right into your setup for that pro-level look and feel.
Seamless Integration for Smarter Boating
Hook it up via a single NMEA2000 cable, and suddenly your MFD becomes a command center. Tap an AIS target on your screen, select DSC call, and you're connected—no fumbling with handsets. Activate Man Overboard on the plotter? Twist the FM4850's knob for an instant distress signal. It shares GPS fixes, AIS targets, and DSC events over NMEA2000 or 0183, breathing new life into older chartplotters too.
Expand to three stations with optional full-function remotes, stretching up to 30 meters. Crew in the cabin, cockpit, or tower stays linked via intercom, no extra wiring hassles. And that Listen Back feature? It's a game-changer for workboats—pick up deck chatter or rod-tip zings through the horn speaker, piped right to the helm speaker.
Weatherproof Reliability You Can Trust
Every component—the transceiver, handset, and speaker—boasts IP67 waterproofing, shrugging off spray, rain, or the occasional rogue wave. Built from tough metal, it's ready for commercial ops or rough weekend runs, with simple mounting that skips the custom fab work.
Real Boaters, Real Scenarios
- Foggy Inlets and Night Runs: Eight fog horn patterns and warning tones cut through haze, while AIS overlays keep tabs on commercial traffic you might miss visually.
- Fishing Fleet Hero: Loudhailer blasts crew instructions or marks territory; Listen Back catches the "fish on!" holler from the bow without yelling.
- Family Cruisers: DSC auto-logs positions for routine calls to marinas; MOB integration adds peace of mind with kids aboard.
- Workboat Workhorse: Multi-station intercom coordinates divers, deckhands, or mates across the vessel, boosting efficiency on jobsites.
Boaters rave about how it cuts response times in hairy spots, turning potential mishaps into non-events. Pair it with an external GPS antenna, and you've got backup nav that steps up when primary systems glitch.
Elevating Safety and Communication Standards
Class-D DSC isn't just a checkbox—it's your lifeline, sending precise position data with every distress or urgency call. AIS receiver pulls in vessel IDs, courses, and speeds up to 20+ miles out (depending on conditions), feeding your MFD for collision avoidance charts. Add the loudhailer's auto-sequencer for automated signals, and you're compliant while staying ahead of trouble.
For those upgrading from basic handhelds, the jump to black box means clearer 25-watt transmit power, programmable channels for local regs, and scan modes that lock on active traffic fast.
Effortless Setup for Any Helm
Drop the black box in a dry spot, run power, antenna, and NMEA lines—done. Handset tucks into a flush mount or cradle; speaker aims wherever you need projection. Furuno's plug-and-play NMEA2000 means no deciphering pinouts or soldering. Test DSC self-diagnostics on first power-up, and you're seaworthy. Pro tip: Position the AIS antenna high and clear for max range.

FM4850 Black Box VHF Radio with GPS, AIS, DSC & Loudhailer
The Ultimate 5-In-1 Tool of VHF Radios
The FM4850 is a marine Black Box VHF radiotelephone with built-in Class D DSC, AIS Receiver, and Simplified Loud Hailer with intercom. Its compact housing enables it to be installed in a variety of craft, even vessels where space is limited, such as center-console boats.The FM4850 handset shares a common appearance with other Furuno equipment, such as NavNet TZtouch2, NavPilot 711C, and the FI70 Instrument series, offering an integrated appearance to any helm. Its built-in AIS Receiver can be used to overlay AIS targets with networked GPS Plotters or MFD's, such as NavNet TZtouch, NavNet TZtouch2, or GP1871F/GP1971F combo units.
Built-In DSC & AIS
An external GPS antenna can be connected to the FM4850, and it can share its own GPS, DSC and AIS information via NMEA0183 or NMEA2000. When connected via NMEA2000 to any NavNet TZtouch2 MFD, DSC calling can be initiated directly from the TZtouch2 MFD by simply tapping on the AIS/DSC target and selecting [DSC Call]. Additionally, when MOB (Man Overboard) is activated on a TZtouch2 MFD, the FM4850 enters a special mode where you can initiate a distress call by simply pushing the rotary knob on the handset.
Loud Hailer, Intercom & Listen Back Features
The unit can operate as a simplified Loud Hailer with intercom, featuring 8 patterns of alert sounds. Loud Hailer, Fog Horn and Warning Signal features are all available, enhancing onboard safety and communications while navigating in the dark or fog. When connected with the second-station handset, intercom communications are available, allowing communications between the two devices. Additionally, the horn speaker can be used to collect external sounds and transmit them through the built-in speaker with a function called Listen Back. In this way, a person on the deck can easily communicate with the bridge, a particularly useful feature for a variety of fishing vessels and workboats. The Listen Back function can also be an effective tool on sport fishing vessels, allowing the horn speaker to collect the sound from fishing rods and lines when you get a strike.

FM 4850 has all the standard functions of VHF radio, such as 25 watt output power, weather channel and Class D DSC. The 4850's high-end features include NMEA 2000 and NMEA 0183 compatibility, so you can connect it to any compatible NMEA device on the board. You can even add an external GPS antenna Furuno GPA017 so that the FM4850 can get GPS data without connecting to a plotter. Not only can you send and receive standard routine calls, you can also use Class D DSC (Digital Selective Calling) for SOS distress calls in emergency situations. The built-in AIS receiver will provide situational awareness to help provide greater safety at sea or in the bay by providing data about other ships. FM4850 comes with a 15-watt PA/Loud Hailer with 8 different automatic fog/warning signals.
