Irrigator Pro 423015 Metal Adjustable Part or Full Circle Metal Impact Sprinkler, 1/2-Inch, Gold

I use a lot of these heads and have tried several other makes. The adjustment from full to part circle is a problem on several makes that use the squeeze clip which frequently weakens and won’t maintain their setting. The adjustments on these heads are easier to adjust and have always maintained their settings. These work well as replacement heads for tripods and also as original heads on the sprinklers I build. I find that the adjustment deflector and screw are difficult to set to maintain an even distribution of water between the sprinkler base and outer limits of the head. The sprinklers work exceptionally well between 40-60 psi and handle the variability in pressures within that range efficiently. If you irrigate with a well as I do, that is important.
