Look at any sprinkler's performance chart and you'll see that the data was gathered from tests conducted under zero wind conditions. Of course, in the real world, not every day is a calm one. And, while most sprinklers can still perform close to peak efficiency with some type of breeze, when air movement starts to get stronger, water coverage can become challenging. It can even become a liability issue when windblown sprinklers soak pedestrian paths or roadways. The Hunter Wind-Clik saves water and enhances system efficiency by shutting off irrigation during high wind conditions. Once conditions have improved, Wind Clik resets the system and resumes irrigation.
