Glad I detected this community, good find!
I live in Northern California very near where gold were first discovered! My wife and daughter bought me a metal detector last year from a pawn shop, a Garrett brand, and I've only used it a few times but have found tons of pull tabs and several lithium batteries so far. It is legal here but only in certain areas as I understand it but living where I do now I'm excited to scope out my back yard and maybe the old rail road behind my house late at night 😉
Anyhow, open to suggestions or advice and I'll post anything I find as I go!
Good luck everyone!
