RDS Self-Reducing Tacheometer / Theodolite
Includes items exactly as shown in photo - includes instrument and bullet case.
This Wild RDS Vertical Staff Tacheometer is designed for use with a vertical staff for tacheometric surveys and setting-out on construction sites.
It can also be used as a normal theodolite, the RDS corresponds to the Wild T16 as a fully-fledged direct scale-reading instrument, with the normal stadia lines however, being replaced by very flat curves projected into the field of view. These flat reduction curves give a direct horizontal distance reading and a height difference involving no tables and only a simple mental multiplication. These readings are read directly as intercepts of a graduated vertical staff at one telescope pointing.
