notes: label: Description
content: The Wild RDS is a normal direct-reading theodolite similar to the Wild T16. Here, however, a diagram of reduction curves is projected into the field of view, enabling the surveyor to read the horizontal distance and height distance as intercepts of a graduated vertical rod. This example is marked "WILD HEERBRUGG SWITZERLAND RDS-171658" and was probably made in the mid-1970s. It has its original airtight and watertight steel case. The U. S. National Imagery and Mapping Agency transferred it to the Smithsonian in 2000.
