Tasmania's natural beauty abounds around every corner, and thanks to its compact size, it's easy to see a good portion of it by travelling just outside the capital city of Hobart. Thankfully, for his readers, McGahan has left us one last gift. This type of theodolite was developed from 18th century astronomical Transit instruments used to measure accurate star positions. There is a long history of theodolite use in measuring winds aloft, by using specially-manufactured theodolites to track the horizontal and vertical angles of special weather balloons called ceiling balloons or pilot balloons (pibal). Each quadrant has a numbered graduation from 0 to 90 degrees. The Leica LDT-05 digital electronic theodolite is designed for enhanced performance in construction applications.

A balloon is released in front of the theodolite, and its position is precisely tracked, usually once a minute. When the object to be measured is too small or too far away. Theodolite surveying is a method of surveying that accurately measures horizontal and vertical angles. The peak he imagines, he said, is not geologically possible, but that didnt stop him explaining how it came about making up outrageous reasons with a whole tectonic plate tipped on its side.
