Virtual Discovery #17 - Depression Range Finder
Part of a series of “Virtual Discovery” presentations featuring the military heritage of Rottnest island produced in parallel with Virtual Visit posts relating to the Australian Army Museum of Western Australia. This “Virtual Discovery” focuses on the Depression Rangefinder, ancoast artillery sighting system which provided target bearing and range.
In Coast Artillery, he depression range finder (DRF) is a precision fire control device used to observe the target's range and bearing in order to calculate firing solutions. It was the main component of a vertical base range finding system. It was necessitated by the introduction of rifled artillery from the mid-19th century onwards, which had much greater ranges than the old smoothbore weapons and were consequently more difficult to aim accurately. The DRF was invented by Captain HSS Watkin of the Royal Artilleryin the 1870s and was adopted in 1881. It could provide both range and bearing information on a target.
