Theodolites | How Does a Theodolite Work - Johnson Level
WEBHow Does a Theodolite Work? A theodolite works by combining optical plummets (or plumb bobs), a spirit (bubble level), and graduated circles to find vertical and horizontal angles in surveying. An optical plummet ensures the theodolite is placed as close to exactly vertical above the survey point.
