Although the equipment appeared similar to that used during the Second World War to detect land mines, it had been in use for more than 20 years.
The article with the picture described how it worked, like a “mechanical eye”, to find lost stop-taps and leaking pipes.The operator would hear changes in sound as the pipes were located.
According to records at Luton Museum in Wardown Park, where an estimated 1.5 million Luton News negatives are kept, the picture was actually taken in August 1950, but not published in the Pictorial for more than two years.
