"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!"
