Abstract : The author certificate presents a self-correcting double-image range finder with a variable instrument base. The latter is formed of two movable pentagonal prisms placed symmetrically in respect to the objective of the viewer tube, and of wedge-shaped compensators producing the parallax angle. To correct automatically the magnitude of this angle in measuring the slope distances without using a rod and to simplify the construction of the apparatus, the wedges of the compensator are rigidly attached to the body of the range finder. They retain their position in respect to the horizon when the viewing tube is inclined.
