Extreme-Duty Confidence for Marine & Autonomous Systems

When equipment lives offshore, on deck, or in dusty environments, exposure is constant and failure is expensive.

The 300WX-IP67 delivers the same next-generation intelligence as the 300WX, but in a fully sealed, IP67-rated housing engineered for continuous exposure to water, dust, vibration, and harsh marine conditions.

This is the model trusted for offshore platforms, buoys, unmanned surface vehicles, commercial workboats, and long-duration autonomous deployments. It’s designed not just to perform — but to endure.

True Wind. True Awareness. Even at Sea.

On moving vessels, apparent wind alone is misleading. The 300WX-IP67 continuously calculates Dynamic True wind by integrating GNSS speed data with stabilized heading and motion data to cancel out apparent wind and deliver the True wind speed and direction. That clarity improves navigation decisions, supports autonomous control systems, and enhances vessel performance optimization.

Built for Harsh Reality

The IP67 enclosure protects against water and dust intrusion, while the proven, rugged housing durability enhances long-term reliability in exposed environments. The 300WX-IP67 removes worry from the equation. It simply continues working — through spray, salt, vibration, and long deployments.

Seamless Connectivity Without Complexity

Like its counterpart, the IP67 model integrates easily into marine and industrial networks, including NMEA 2000®, NMEA 0183, J1939, and ISOBUS systems. Bluetooth** connectivity with Airmar's CAST™ enables remote configuration and firmware updates without removing it from its installed location — especially valuable for mast-mounted or difficult-to-access installations.
