Description
Instrument described by Philippe Danfrie, which may be seen as a half compass. The magnetic needle and the diopter are found in fact at the centre of a semicircle with a degree scale, attached to a fixed base that carries sights. For measuring distances and surveying territories, the instrument requires two stations, whose alignment is verified through the sights on the fixed base. The diopter measures the position angles, which are later transcribed onto charts.
