Commentary:
This miniature micrometric theodolite, about 13 centimetres high, was used for triangulation and for general use. Because of its small size it could be easily carried up mountains so was often referred to as a mountain theodolite. It reads to ten seconds. Advantages and disadvantages of this instrument:
1. The extreme light weight made it desirable for carrying long distances on foot in the bush.
2. With a metal centering rod, it could be used for setting a constant “height of Instrument”. This method was used for carrying three dimensional surveys.
3. Its accuracy in calm weather was excellent, however, its light weight was a disadvantage in windy weather.
3. Its tiny operational knobs required a deft experienced touch, especially in winter.
4. The small telescope did not allow for daylight star observations.
