Geodetic sighting instrument with a gas laser light source and beaming, sighting and observation systems; the optical axis of said gas laser is arranged in a way free to rotate about a vertical axis and perpendicular to the direction of sighting. The instrument has a light reflecting system consisting of directive mirrors to direct the beam used for the marking of direction, a sighting reflecting device being interposed between said gas laser and said observation system including at least one reflecting device free to rotate about an axis perpendicular to the direction to be marked out.
