I asked myself that question before .It has happened to me dig and dig and nothing. good post
All of us have sometimes chased that ghost signal. The trouble is that anything that deep is going to likely be something huge. I've found those thunks of conduit and water pipes 10 inches down or more. If I get into pin pointer range and the object seems to be bigger than a baseball, I call it!
My favorite was the original and defunct sprinkler system at a 100 year old city park.
Wonderful looking brass heads too!
