Automatic Levels
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 Survey Supply, Inc. 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.
