Automatic Level

An automatic level or builders level is an optical type level that is said to be self-leveling.  When the bull's-eye bubble has been centered, the automatic level is close to being set level.  An internal compensator mechanism in the form of a swing prism then automatically removes any residual disparity from the builders level.  This is done quickly within the automatic level by a damping device so that the observer does not have to wait until it settles on its own accord.  The builders level has the advantage of offering very rapid instrument setups and of eliminating random errors in centering the level bubble.
