ABSTRACT:
A target is disclosed for intended use with light-emitting, including laser-emitting, electronic distance measuring equipment. The target includes a body having a substantially spherical surface to which a plurality of discrete multi-faceted return reflective elements are fixed. A plurality of guard pegs are interspaced between the reflective elements and extend outward from the surface of the body substantially beyond the outer surface of the reflective elements for protecting the reflecting surfaces from abrasion.
