The backstaff is largely obsolete in modern navigation, having been replaced by more accurate instruments like the sextant and advanced electronic systems such as GPS. However, it may still be used in specific educational contexts or by enthusiasts of traditional navigation methods. While it played a significant role in maritime navigation during the 17th and 18th centuries, its practical application today is minimal.

How does a backstaff work?
A backstaff is a navigational instrument used to measure the altitude of the sun. It consists of a graduated arc and two vanes, one of which is moved to block the sun's image as it is reflected onto a mirror. By aligning the shadow of the vane with the horizon, sailors can determine the sun's altitude and calculate their latitude.
