Constructed of a special brass alloy, treated and enameled to prevent corrosion. The handle is slightly inclined to provide a more natural grip. A bubble attachment and astigmatizer lens are available. The sextant has a guaranteed accuracy of better than 9 seconds of arc. This accuracy includes so-called “instrument error” which indicates the high standard to which these instruments are manufactured.
