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.

A transit level is an optical instrument, or a telescope, complete with a built-in spirit level that is mounted on a tripod. Transit levels are used mainly for surveying and building, but they can be used to determine the relative position of lines and objects as well. Transit levels are very precise.
The transit and theodolite are used by the surveyor to measure both horizontal and vertical angles. While the purpose of the two is similar, as a general rule a theodolite is more accurate than a transit. However, there is no specific rule as to when one definition ends and the other begins.
A Surveyors Transit should be displayed on a shelf as an artifact and not used for any kind of surveying. If you're very careful, a small building could be laid out. The successor to the transit is the theodolite and very few surveyors still use them. I keep one around but I'm considered an old timer.
