The benefit of Rain Bird(TM) Dual Spray nozzle with 9'-12' Spray Distance is clearly visible in side-by-side comparisons with standard, single-orifice spray nozzles. The second orifice on the Dual Spray allows for superior close-in watering. With the efficiency of Dual Spray nozzles, you may reduce watering times by more than 30%. Patented Dual Spray Water flowing from both orifices results in a lower scheduling coefficient. This efficient design conserves water, saves money and reduces waste.
