1928 Marine Observer June 115/2 This vessel is fitted with the Admiralty Echo Sounding machine.., a wonderful aid to navigation, as one is able to get soundings up to 135 fathoms with accuracy.

1947 Times 3 Sept. 5/6 Thanks to echo-sounding, one of the most marvellous inventions of our days, belief in the perfect smoothness of the deep-sea bottom has been much revised, especially in regard to the Atlantic.

1968 Times 18 Oct. 16/7 By a combination of echo-sounding from the air and rapid sampling it was found possible to determine in only 20 minutes the main features of any lake.
