Abstract
An apparatus and method for mounting a range finding instrument to a theodolite telescope incorporates the necessary geometry to enable a linear spring assembly to be able to accurately balance the mass of the range finder and theodolite combination rotating in a vertical plane about a pivot point defining a first axis. In a particular embodiment of the mounting system, two compression springs are mounted in a single straight spring tube which is attached to the range finder but is allowed to rotate about a second axis. The resultant geometry of the arrangement provides a substantially exact balance for the weight of the range finder irrespective of the vertical angle of the theodolite telescope.
