My SNO-T certificate shows +10" everywhere on the arc, which is nonsense by itself. I also spent some euros for the fun of having it certified by both Freiberger and Cassens-Plath last summer:-) In fact, my Russian manual says that a sextant should be certified EVERY TWO YEARS. SNO comes with many pages certificate where the first page is filled by the manufacturer and the rest are supposed to be filled in "special workshops" every two years. > I find it odd that an instrument maker would use this sort of convention. Not every manufacturer. Cassens-Plath does not make a usual certificate, just a statement that "the error is negligiblei for practical purposes", whatever this could exactly mean:-) Alex.
