Usborne's Fall of Shot Indicator[1]

Usborne's Fall of Shot Indicator was a specialised timer to help in assisting Spotting by sounding an audible alarm when one's own shots were about to fall about the target.

Performance

The Grand Fleet Dreyer Table Committee complained that the present design in service was unreliable and did not meet the demands of double salvo firing. It was suggested that device be made to work with the "timing shaft" and gun range on the Dreyer Table.[2]
