theodolites
Angle-measuring survey tools
Theodolites is the plural of theodolite, a precision instrument used in surveying to measure horizontal and vertical angles.
Mounted on a tripod, it allows surveyors to calculate distances and elevations across terrain: The crew set up their theodolites along the property line.
Modern versions incorporate digital displays and lasers, though the basic optical design dates to the sixteenth century.
