I live in FL. and I replaced my old Hunter Rotary heads, the ones where you needed the tool/key to make any adjustments, several years ago. I installed the Rain Bird pop ups with the R-van rotary heads (first generation). I like the R-Van nozzles. You can adjust the spray radius just by pushing down on the nozzle and turning it. You adjust the distance by turning the wheel on the nozzle. It real EZ and no tools required. I haven’t had the need to research new nozzles but I’m guessing all manufactures now have tool-less adjustments. I just looked on Rain Bird website and they have new generations of rotary nozzles.
