What is the difference between transit and non transit thiodolite?

Transit theodolites have a telescope that can be transited (rotated) to measure vertical and horizontal angles. Non-transit theodolites have a fixed telescope and can only measure vertical angles. Transit theodolites are more versatile and commonly used for surveying tasks that require both horizontal and vertical angle measurements.


Why do surveyors use theodolites?

Surveyors use theodolites to measure angles in the horizontal and vertical planes with high accuracy. This allows them to determine directions and elevations of various points on the land they are surveying. The data collected from theodolites is essential for creating maps, construction projects, boundary delineation, and other surveying applications.
