Description
The Furuno 200WX is a solid-state ultrasonic marine weather station for boats that need more than basic wind speed and direction. It measures apparent and true wind, pressure, air temperature, humidity, dew point, wind chill, pitch, roll, heading, GPS position, speed over ground, and course over ground. It is a sensor hub, not a display, so the data must be viewed through compatible NMEA equipment.
Because the 200WX uses ultrasonic sensing with no moving parts, there is no cup assembly or mechanical vane to service at the masthead. It accepts 9-40V DC and draws about 120mA at 12V, while NMEA 2000 and NMEA 0183 provide the listed data paths. The IPX6/IPX7 housing and 1-inch-14 mounting thread suit exposed installations. Its alarm strings can broadcast storm-pressure and high-wind warnings to compatible network equipment.
Key Features
- Ultrasonic wind measurement – Provides wind data without moving cups or a mechanical vane.
- Weather sensing – Measures pressure, air temperature, humidity, dew point, and wind chill.
- Motion and navigation data – Provides pitch, roll, heading, GPS position, SOG, and COG.
- NMEA 2000 and NMEA 0183 – Shares weather data with compatible marine systems.
- 9-40V DC input – Fits a wide range of vessel power systems.
Who Is This For?
This ultrasonic marine weather station suits bluewater cruisers, research vessels, commercial fleets, and large offshore sportfishers that need full weather telemetry. It is not ideal as a standalone wind display, because the sensor requires compatible NMEA equipment to present and use the data.
Compatibility
Confirmed compatibility includes NMEA 2000 through Micro-C, concurrent NMEA 0183 communication, a 1-inch-14 mounting thread, and compatible marine navigation systems. The supplied information does not identify specific chartplotters, radar, autopilot, or display models. No named incompatible system was provided; verify NMEA messages and mounting requirements before installation.

Warranty & Support

The 200WX is the most capable environmental sensor in this group, measuring weather, motion, and navigation data without moving wind hardware. Its trade-off is integration: it needs a compatible display or network to turn that data into useful pages and alerts. Choose it for complete weather telemetry, not for a simple standalone wind gauge.
