When many people hear about treasure-hunters and archaeological findings their minds automatically go to Indiana Jones and Lara Croft. That’s not to say regular people can’t become real-life treasure hunters! It just takes a bit more work.
That is unless you’re Brad Martin of Green Mountain Metal Detecting. This metal detector enthusiast has made a living out of the hobby. What he found one day while exploring made all of his expeditions worthwhile.
The Modern-Day Metal Detector Was Invented By Gerhard Fischer
The modern development of the metal detector didn’t start until the 1920s when Gerhard Fischer developed a system of radio direction-finding. It was a machine that would become distorted when it came in contact with metal-bearing rocks. He reasoned that if metal could alter the radio signal, then he should be able to produce something that detects metal.
In 1925, Fischer applied for, and was granted, the first patent for a metal detector. Obviously, he had no idea that it would become a go-to tool among treasure hunters!
