    "But one adjustment that does NOT  EVER
    need to be made is the zeroing of index error, whatever it may be."
    The Plath companies apparently disagree with you, George. Their sextants are
    built with an extra wheel and scale to allow the user to zero out the index
    error. Would I do this every time? No, certainly not. But it is something that a
    user certainly would do the first time they got the sextant, and were trying to
    set up a baseline of adjustments on it, including the mirror positions.
    More like, to quote Gilbert & Sullivan's Mikado, "Never? Well, hardly ever!"
