Abstract
Abstract A surveyor''s sighting target for use on a surveying monument comprises a strip of stiff, foldable material including a body portion having a pair of feet connected to one end, an index mark on the body portion, and an opening through the body portion at the line of connection of the feet. In use of the target, the feet are spread apart and affixed to a surveyor''s monument having the usual reference cross on its surface. By looking through the view opening and lining the index mark on the target with the cross on the monument, the surveyor is able to locate the target precisely in the proper position.
