Tellurometer

Known as a microwave distance-measuring device, the Tellurometer was invented by Durban’s own Dr. Trevor Lloyd Wadley in 1959. Here’s how it works: the Tellurometer spits out an electronic wave, a remote station absorbs and re-sends the wave back in a more complex form, and the distance the waves traveled is measured. It is mostly used to survey rough terrain, especially between mountain tops.
