Once I retire, I plan to buy a metal detector, and have lots of good hunts.
I have a friend who is 90. He had a good paying job, but got so good at detecting, he retired early and took up detecting (highly specialized objects) full time, and made more money. Fantasic guy, and he is a world class expert in his chosen field. He is doubly retired now.
Of course, he mined out the best areas decades ago.
I trust you know of The Detectorists, and have watched the same.
Wifey and I returned from a week at the shore, where metal detectors had been in use on the beach. Driving down a rural road, a guy with earmuff hearing protectors was weedwhacking around the end of his driveway. As we passed him, my missus spoke up, “What does he think he’s going to find around there?!” After a few seconds I realized she’d mistaken the guy’s weedwhacker for a metal detector! I nearly wrecked my car trying to see through the laughter and the accompanying tears. When I explained her mistake, she cracked up, too. 🤣
A relic hunter has had a great time with my front pasture. Found lots of interesting artifacts - including a Union army belt buckle in pretty good condition. Plus of course a lot of scrap metal!
