Abstract
An apparatus that projects the horizontal and vertical axis of an object to be aligned for ready sighting by survey instruments is disclosed. The device consists of a v-frame with a rotatable head to which a target platform for mounting a vertical or horizontal scale may be affixed. The v-frame is held on the object and moved about the object until the surveyor can see the target scale without having to remove ancillary equipment that would ordinarily obscure the target. Standard surveying methods may then be used to align the object.
