Shoutout to the guy at Ocean Beach who showed me the real way to sift sand
I used to just grab big stuff off the top at Ocean Beach in San Francisco, but he had a 1/4 inch mesh screen and found 37 cigarette butts in a 2 foot square I'd already walked over. The tiny bits matter more than the big bottles because fish eat them, and I never would have known if he hadn't taken two minutes to show me. Now I screen every patch first. Does anyone else have a trick like that for tiny plastic pieces?
Sifting is the move, but the trick that really changed things for me was doing it right at the water line after a wave pulls back. Everything small gets left behind in that wet strip and a kitchen strainer works just as good as a fancy screen. Also check around storm drains and the seaweed line, since nurdles and tiny bits pile up there way more than out in the dry sand. Takes like ten extra minutes and you'd be shocked how much you pull out.
Hold on, 37 butts in a spot you already walked over? That is wild. I always figured once I grabbed the big stuff I was done, but clearly I was just fooling myself. The water line tip makes so much sense too, all that stuff has to go somewhere after a wave drags back. Next time I hit the beach I'm bringing a strainer and hitting that wet strip first thing.
