Sailors have used instruments like this sextant for years, to navigate the seas. It can be used during the day or night and requires only the sailor’s view to measure the angle between the horizon and a celestial object (like the stars or the sun).


Its elegant ingenious design has remained consistent since the sextant was first used in the 1700s.  Borders, governments, ships and even sea temperatures have changed in that time, but the mathematics and geometry behind this ancient tool have remained reliable and perfect.
