How it measures wind speed
The masthead unit has a rotor with three windcups
which spins as the wind moves past the boat. The
masthead unit measures how fast the rotor is
spinning to calculate the wind speed.
How it measures wind direction
The masthead unit has a windvane which points in
the direction that the wind is coming from. The
masthead unit electronically senses the direction the
windvane is pointing.
Cleaning and maintenance
Clean the display unit with a damp cloth or mild
detergent. Avoid abrasive cleaners, petrol or other
solvents.
