In the world of surveying, civil engineering, and construction, precision is not just a goal—it is the standard. Among the most critical instruments used to establish this precision is the theodolite, a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. These are the classic mechanical instruments

Old optical theodolite manuals (e.g., Wild T2) have entire chapters dedicated to determining true north using sun shots or Polaris observations. This is still valuable for remote boundary surveys.
