When did electronic theodolites first appear?

The development of electronic theodolites marked a significant advancement in surveying technology. These instruments began to appear in the 1960s when manufacturers began to integrate electronic components into traditional optical theodolites. This transition allowed for improved accuracy and ease of use, as electronic readings and digital displays replaced manual readings.

The 1960s also saw the rise of other technological innovations in surveying, which fostered a demand for more efficient equipment. As a result, the electronic theodolite gained popularity among surveyors who were looking to enhance productivity and reduce human error in their measurements. The advancements made during this decade laid the groundwork for further developments in surveying instruments, including total stations and GPS technology in subsequent decades.
