The GARDENA Premium Full or Part Circle Pulse Sprinkler Head (model 8137-20) is a durable, adjustable sprinkler for medium to large garden areas. It combines metal and plastic components for stability and can be screwed onto a tripod or a water pipe with a 21 mm (G 1/2) mating thread. The sprinkler delivers uniform coverage with a high-precision brass nozzle and offers an adjustable sector and range for targeted irrigation.

Advantages
