Crop circles of the golf kind
Here is one example.
Dry area 6 feet in diameter around sprinkler head.
Watching the spray pattern indicates a faulty short range nozzle.
Inspection reveals a worn tip on the short range nozzle, shown in the photo on the furthest left nozzle. Compare a newer short range nozzle on the assembly on the right.
One down, a thousand more heads to go!
