Found a second AOUW medal today. Along with a large flat button. First bigger one ive found. Some newer change. A rock that makes my detector go bonkers. And a few others. Hot about 3/4 of my yard done. Gotta do right around the house mext. Dog invisible fence is gonna make it rough though
hum a lock box or chest key lock type front plate ---wonder what became of whatever items was "locked up" in it ? if it is under lock and key its worth something normally
those types of rocks are typically called a "hot rocks" most likely it has some sort of metallic element within it ..that triggers the detector
any type of device that emits a electrical signal will often cause issues with detectors ...many times you got to really lower sensitivity to avoid picking up the "leaked electric energy" --which can trigger your machine into falsing ---beep beep beep non stop --sometimes sadly it just can't be done if its too bad --powerlines and generators are often a pain too ---salt water wet areas of beach as well --since salt water has micro elements in it of gold and other elements in it
