Pre -owned with some signs of wear, but all functions working correctly when last used. This is a plastic sextant, so lightweight and easy to use.

Packs neatly into its own carrying case and included is a handy book "Celestial Navigation For Yachtsmen" as the original instruction book couldn't be found.
