Welcome to our selection of antique octants. 

The antique octant is a very desirable maritime instrument, they are also a symbol of seafarers who have navigated the worlds oceans by using only the sun and stars for fixing their position. The primary use of a navigation octant is to determine the angle between an astronomical object and the horizon for the purposes of celestial navigation. The angle and time can be used to calculate a position line on a nautical chart. Common uses of the octtant include sighting the sun at solar noon to determine latitude.
