All I ever find with my detector is old beer can pull tabs and nails...............
Archaeologists of the future will conclude that pull tabs must have been a form of currency, or maybe they had a ritual purpose. And in a way, they’d be right on both counts. :^)
I got a very nice Whites metal detector for Christmas when I was a teen in the 70s. The excitement of digging up buried treasure everywhere faded when I realized it was more like I was working as an unpaid trash collector. Pull tabs were especially bad back then, though the discriminator circuit worked fairly well to screen out aluminum.
We moved to Colorado shortly after that, and my dad and I hit every ghost town we could find. I picked up quite a few signals from the detector, but quickly found out why they call the area the Rocky Mountains. It was one thing to detect something (whatever it was), but quite another to dig through the solid rock that was beneath most soil up there. It still provided a lot of adventure and got me out to places I might not have explored otherwise, though.
