NASA Wireless Masthead Wind Sensor — NMEA 0 | 4Boats

Compact wireless masthead anemometer that sends wind speed and direction to a wired base receiver for connection to NMEA 0183 displays and chartplotters.

• NMEA 0183 output from base unit to compatible displays
• Wireless transmission from masthead to base receiver — no mast wires to route
• Solar-powered masthead with internal rechargeable battery
• Operating time (from full charge) > 2000 hours
• Lightweight: 0.19 kg (0.42 lb)
• Simple masthead alignment via the base unit
• Ideal for sailboats and small craft — easy installation

The masthead unit transmits reliable wind data to the base receiver, which provides a wired NMEA 0183 connection to displays and chartplotters. Low weight and long battery life make it suitable for extended cruising without running mast cabling.
