Hunter I-20 Rotors

If you've ever desired the convenience of being able to use just one rotor to cover all of your needs, here it is
Got a small area for which you don't want to create a separate spray zone?
Is a portion of your landscape in sandy soil?
Is the landscape a mix of shrub zones and expanses of grass?
Does one part of the turf require a higher cut?
With all the features on today's I-20 Ultra (most notably its ability to effectively cover a radius range from 17 up to 47 feet), there's a single-sprinkler alternative to stocking a variety of rotors and sprays. With over 20 different nozzle choices, including stainless steel, the Hunter I-20 Ultra rotor can handle all of your irrigation needs.
