Weirdest find ever! Metal detecting TreasurePro Fisher F2. Pinoy. Live digs 

I finally made it to Rhode Island to detect with my friend Bill. He found something that required his plug to be re-sized a few times. What is it?
Yes. I dig the jumpy pulltabs and foil signals. It would bother me to no end to think that I left something, possibly, valuable in the ground. 😂
