    I'm sure this has been explained before, but, I was wondering about the significance of the various letters preceding the model number of Scubapro 2nd stages. I own a bunch of Rs, Gs, and Ss

    A700
    C370
    D420
    G260
    R195
    S600

    Thanks

    I thought it had to do with who designed it.

    Gustav Dalla Valle designed the G250,

    Dean Garraffa designed the D350

    So I wonder who A, C, R, and S are?

    Maybe some comments by the regulator regulars, @couv @Luis H @herman @halocline @rsingler ...?

    A - Alberto Belloni
    C - Corrado Cominetti
    R - Roberto Semeia
    D - Doug Toth
    G - Dean Garaffa
    S - Roberto Semeia

    Interesting. Why no prefix for the 108, 109, and 156?

    I've always called my first regulator, bought in 1972, still in operation today, the R109. I don't know about the 108 or the Balanced Adjustable
