Always on the right track!
The first compass-like instruments were already being used for navigation by the 11th century. And even today, in the GPS era, people still use a compass to orient themselves at sea, or when out hiking. A compass needs no power supply and does not depend on good satellite reception.
In addition to compasses, we also offer a range of other measuring instruments such as - map measurers, altimeters, anemometers or even a beautiful ‘old-fashioned’ sextant.
