Theodolites have an internal optical device that makes reading circles much more accurate than other instruments. Also, because the theodolite allows you to take fewer repeat readings, these measurements can be made much more quickly. Theodolites with optical instruments have advantages over other layout tools.

Total stations are the primary survey instrument used in mining surveying. [citation needed] Underground mining. A total station is used to record the absolute location of the tunnel walls'', ceilings (backs), and floors as the drifts of an underground mine are driven.
Whilst it is true that mine surveyors in Deep/Underground mines do also carry out surveys above ground, their main work is carried out hundreds of meters underground. The coming of global positioning system (GPS), total station and digital theodolites has made the acquisition of data much simpler and faster than hitherto was the case.

A theodolite / θ iː ˈ ɒ d ə l aɪ t / is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but they are also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching.
Mine has been developed to provide valuable information to students about the mine surveying profession. It is our intention to address the shortage of mine surveyors in Australia and encourage the involvement of school leavers and university students in the profession.
A Theodolite is a instrument for measuring both horizontal and vertical angles, as used in triangulation networks, and geolocation work. It is a tool used in the land surveying and engineering industry, but theodolites have been adapted for other specialized purposes as well.
