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.
