hot rocks

  1. Hot Rocks Signals

    Have a question for those that have been detecting longer than my short 7 weeks. I have found three hot rocks with my Vaquero. Seems like they all give me a double beep instead of single one. Also, why would my White's Bulleye II pinpointer not signal them. They are hot out on the ground still...
  2. strange rocks wash up on beach... what are they?

    I found these rocks washed up on New Smyrna Beach and ordinarily I wouldn't have picked them up, but they all had a signal of 80-85 on my detector..... Can you identify what these are? They registered in the are of silver (and aluminum cans)..... Just Curious because we usually don't get hot...
