An impact head is the sprinkler everybody pictures — the one going tick-tick-tick across the yard. We bought those first. They are not as reliable as they look.

It turns every time

A gear drive is turned by the water passing through it, so as long as water is moving, the head is coming around. The impact heads we ran before this would quit rotating on us, usually when the pressure was down, and you come back out to one dark green stripe and a dry yard. These hold their distribution at pressures where the impact heads stalled, and they are quiet enough to run at first light.

Run two at once

Split a hose and run a pair of these together and they still lay water down evenly. Put one on each port of a four-port timer and the yard runs on a schedule — no trench, no valve box, nothing to blow out in November.

Set it to the shape of the yard

Two stops on the cap set where the sweep starts and ends, from a 25-degree wedge to a full circle, and six patterns click in by turning the labeled collar. The throw is long when you want it, and the diffuser pulls the radius back in for a side yard or a strip of new sod without soaking the driveway.

The verdict

This is the working end of a hose-and-timer setup, and the reason to pick it over an impact head is that it turns every time.

Skip it if

You are watering a long, narrow strip. A rotor throws a circle, and an oscillating sprinkler fits a rectangle better even though it waters it less evenly.
