We have the heads that do a mist in a circle (small). I think we have 4
to a Zone and we have 4 Zones for a 1/4 of an acre in Massachusetts.

We have some neighbors that have a swivel that go back and forth and
they cover larger areas. But they have fewer heads. It sprays high in
the air. These systems were put in 1-2 years go. The size of the lot is
the same as ours.
But they have alot of water wasted, as it runs down the street.
