A surveyor’s best friend, the theodolite is used for many purposes in their line of work. In this article we’re going to cover some common questions about them; what they’re used for, how to use one and how they work, along with the benefits of hiring one versus buying your own.
What is a theodolite used for?
To go right back to basics, a surveyor’s job is to make precise measurements of areas, usually for engineering, construction or mapmaking. The theodolite is essentially the most accurate instrument to measure the horizontal and vertical angles to work this out. But they can also be used for locating points on a line, prolonging survey lines and finding differences in elevation.

How Does a Theodolite Work?
Just about every theodolite in use these days is digital. Digital theodolites work by combining optical plummets, a spirit (much like a spirit level) and graduated circles to find vertical and horizontal angles. The plummet ensures placement exactly above the survey point. The spirit makes sure the device is level. The graduated circles, one vertical and one horizontal, allow the user to actually survey the angles.
Hiring Vs. Buying
This question all comes down to your individual needs, if you will be using it frequently and over a long period of time, buying a theodolite outright can be the right choice. However, even with regular use there are still drawbacks to buying outright, such as not having the latest technology, being responsible for servicing and maintenance and having a depreciating asset.
