The vast majority of the world's electronics run on 1960s and 70s technology, it's not just ham radio.
Yeah it's crazy how little modern tech has made it to different niches. I was looking into metal detecting a few years ago, and there is basically no technology to any of them, even the expensive ones. You'd assume they'd have fancy android powered devices with gps and stuff, but no it's the same basic circuitry they've had for decades.
The base circuitry for detecting metal probably hasn't changed much (at least not for amateur prices), but there are apparently modern metal detectors with app integration and gps and the like: https://apps.apple.com/be/app/go-terrain/id1419674707
Huh. Now you are making me picture a metal detector design with an array of overlapping current loops and a fancy deconvolution software on top that gives you an image (probably very fuzzy but still an image) of what magnetic source its detecting. Could be pretty cool!
