About This Product
A wind vane turns freely on a spindle so that it points into the wind and shows the direction the wind is blowing from. Weather observation lessons use it together with a rain gauge and a barometer to record daily conditions. Low friction and good balance help a vane respond to small changes in direction without favouring one side. This model is intended for fixed mounting on a building.
