not a bad guess for the elderly since if I am not mistaking metal detectors may have started in WWII as mine detectors.
iirc, in 1881 the first one was invented/used by Alexander Graham Bell trying to find the bullet in a dying President Garfield. They were unsuccessful because of the metal bedframe + the doctors would only allow Bell to look on one side of the body. The doctors "knew" where the bullet was and of course, they were wrong- it was on the other side of his body.
But yeah, modern metal detectors are descended from war metal detectors. Minelab makes (or used to make) the NATO mine detectors.
