What is Auto Level?

Auto Level refers to a feature commonly found in surveying instruments, particularly levels and total stations. It automatically compensates for minor instrument mislevelment, ensuring that the line of sight is truly horizontal (level). This is achieved through an internal compensator, typically a prism or pendulum-based mechanism, that adjusts the line of sight when the instrument is slightly tilted. Auto-leveling drastically reduces the time and effort required for accurate surveying measurements, as the operator doesn't need to painstakingly adjust the instrument to a perfectly level position manually.
