A theodolite is used to measure both horizontal and vertical angles. It is an important tool for individuals specializing in triangulation networks and geolocation work. Beyond the fields of surveying and engineering, theodolites are useful in creating floor layouts and working with concrete slabs. You may also need a theodolite for work on golf courses, swimming pools, landscaping, or road design. Theodolites can be used to measure elevations, but auto levels will do this more accurately over long distances.

 

An auto level is a professional-grade leveling tool used by builders and surveyors who depend on accurate leveling at every turn. They are fast, easy to use, and help to conserve financial resources during a variety of projects. Some auto levels sold at Engineer Supply come in kits that include a grade rod and tripod for convenience and ease of use. Auto levels need to be leveled by hand at first, but they have a built-in system that allows you some margin for error and takes over the process to create an automated, accurate measurement. An auto level cannot measure vertical angles and has limited accuracy in measuring horizontal angles. If your project requires those measurements, make sure you have both an auto level and a theodolite on hand.
