Furuno 200WX Ultrasonic Weather Station

Imagine navigating open waters with real-time insights into shifting winds, temperature drops, and precise vessel orientation—all from a single, rugged device. The Furuno 200WX ultrasonic weather station delivers exactly that, empowering sailors, anglers, and yacht owners to make informed decisions that enhance safety and performance. Unlike traditional anemometers with moving parts prone to icing or mechanical failure, this sensor uses ultrasonic technology to capture instantaneous weather shifts without interruption, even in pounding rain or freezing gales.

Precision Sensors for Unmatched Marine Data

At its core, the 200WX packs a suite of advanced sensors into a compact package. It measures both apparent and true wind speed and direction with exceptional accuracy, factoring in your boat's motion for reliable true wind data. Air temperature and wind chill readings help you anticipate crew comfort and hypothermia risks during long passages. A built-in barometric pressure sensor tracks approaching fronts, while optional relative humidity adds dew point and heat index calculations for comprehensive environmental awareness.

The integrated 3-axis solid-state compass provides dynamic stabilization, compensating for heeling and pitching to deliver heading data you can trust. Paired with a 3-axis rate gyro and accelerometer, it offers best-in-class pitch, roll, and rate-of-turn information—crucial for autopilot adjustments or instrument calibration in rough seas. When connected to GPS, it even derives speed over ground and course over ground, creating a holistic picture of your vessel's behavior relative to the elements.

• Wind Data: Ultrasonic apparent/true speed and direction—no cups or vanes to freeze or break.
• Temperature & Comfort: Air temp, wind chill, dew point, heat index (with humidity option).
• Orientation: 3-axis compass, gyro, accelerometer for stabilized heading and motion.
• Pressure: Barometric trends for weather forecasting at sea.

Effortless Network Integration

Designed for modern boating networks, the 200WX speaks NMEA 2000 and NMEA 0183 fluently, plugging directly into NavNet TZtouch systems or any compatible chartplotter. Power draws straight from the NMEA 2000 bus, eliminating extra wiring runs. This drop-in connectivity lets you daisy-chain multiple sensors, distributing vital data across your entire setup—from radar to autopilot—without cluttering the helm.

Installation is straightforward with the included 6m drop cable, B-Bone cable, power tee, and NMEA 0183 antenna cable. The standard 1-inch mount fits existing hardware, so retrofitting is a breeze. Operators appreciate how it converts and shares NMEA 2000 data network-wide, ensuring every display gets the full weather feed.

Built to Withstand the Harsh Marine Environment

Engineered for relentless exposure, the 200WX features a UV-stabilized, chemical-resistant housing that's fully waterproof to IPX6 standards. It thrives from -13°F to 131°F (-25°C to 55°C), sipping just 1.7 watts at 9-40V input. At 2.83 x 5.16 inches, it's unobtrusive yet tough, resisting corrosion from saltwater spray and deck washes.

This durability translates to peace of mind: no more worrying about sensor failure mid-voyage. The field-serviceable humidity option extends its versatility without compromising the sealed core.

Real-World Applications for Boaters

For coastal cruisers, the 200WX flags sudden squalls via pressure drops and wind shifts. Offshore racers leverage true wind data for sail trim optimization. Fishermen monitor wind chill to protect against sudden chills, while liveaboards use heat index for cabin climate control. Integrate it with your MFD, and overlays show wind barbs, temp contours, and motion-compensated headings—elevating situational awareness to pro levels.

Maintenance is minimal: periodic lens cleaning ensures ultrasonic accuracy, and the no-moving-parts design slashes downtime. Backed by a solid reputation in marine electronics, it's a long-term investment in safer, smarter voyages.
