Weather Stations

Enhance your turf's quality with Spectrum's WatchDog* weather station. By harnessing real-time evapotranspiration (ET) data, you can precisely irrigate using CirrusPRO for optimal results.

*Must be purchased through Rain Bird to be compatible with Rain Bird Central Control.


Efficient Water Management
CirrusPRO uses weather sensor input to determine ET rates based upon a field-proven proprietary equation for ET.  
Updated weather data can be viewed in CirrusPRO and used to calculate ET to determine irrigation times for the entire system or by specific areas or stations. 
Generate reports in CirrusPRO to show current or past weather conditions by the hour, day, week, month or year. 
Easy to Use and Expand
CirrusPRO makes it easy to add multiple weather stations and connect them with specific areas of the golf course to provide precision control.  
WatchDog weather stations with CirrusPRO are simple to set up, configure and integrate. 
WatchDog offers five additional ports for increasing sensor inputs.
