Abstract
A light weight surveying pole which is of robust and highly accurate construction. The pole may include two or more pole sections which may be screwed together to make a longer pole. Fittings for use in screw-together pole sections are constructed to permit location within mating pole sections prior to application of adhesive for greater precision and maintenance of coincident axes of the pole sections when screwed together. Also, the end faces of the fittings are particularly formed to facilitate complete face-to-face contact and avoid misalignment when the pole sections are connected together.
