    i think the charts are funny. the gpm increases with arc increase, so././././././././././././././ and i have very evenly green lawns with square spacing. but i can see the what you are talking about. either way, they work and work very very well.

    It isn't the arc increase numbers so much as pressure increase numbers, which make the 3500's water more heavily.

    The 1000's have the exact same precipitation rate as the 3000's, so you shouldn't have any difference in runtime if all variables are the same (sun, grade, soil type, plant type, etc.) In fact, they basically all have the exact same precipitation rate (hence the name Matched Precipitation Rotator) with the lone exception being the 3500 does stray off just a bit on that, but I still say it's awfully close in a relative world, especially based on the alternative broadcast methods.

    true

    but, i think i get better coverage if i run the larger ones longer, since they are putting down the same water, over a larger area. math tells you one thing, experience tells me another......know what i mean?

    ƒ Are the terms “Low Precipitation Rate” and “Low
    Flow” interchangeable?
    – NO – Flow measurements consider flow only. Precipitation rates
    consider both flow and irrigated area. A golf rotor can have a 70GPM
    flow and a low precipitation rate since it covers such a large area.

    another interesting find, the pgj has a better overall mpr than the larger sister the pgp............and interestingling enough also, the rb5000 standard nozzles have a lower precip rate than the mpr nozzle sets, but almost half.
