Sextant

From Editable Codex

Sometimes, even Peer Gems are useless when lost deep within the wilderness or far outside on sea. However, a simple, yet extremely useful tool can help: the Sextant. With this tool and a map of Britannia divided in latitudes and longitudes, it is possible to calculate the exact geographic position with the help of the sun or the stars. With a tool like this, it is easy to find the right way. The Sextant won't work under roofs or in caves (logically).

The Sextant first appeared in Ultima IV, but it could only be bought in Vesper when asking for item "D", which wasn't on the list. In Ultima V, the Sextant can be obtained from David in the lighthouse Greyhaven, after getting information from Buccaneer's Den first. By Ultima VI, it was a standard item and could be bought from the lensmaker in Moonglow. In Ultima VII, shipbuilders sold them and for the first time they were usable with a map to show automatically the position. The same in Ultima VII/2 (but both had to be found first). In Ultima IX, the same rules applied.
