An Abney level is an instrument used in surveying which consists of a fixed sighting tube, a movable spirit level that is connected to a pointing arm, and a protractor scale. An internal mirror allows the user to see the bubble in the level while sighting a distant target.  It can be used as a hand-held instrument or mounted on a cross staff for more precise measurement and it is small enough to carry in a coat pocket
