One of the things that drive many detector operators crazy in certain goldfields is the presence of hot rocks. These are stones that have a mineralization and response significantly different than the surrounding soil and gravel. They have a magnetic response and contain mineral levels either much more or much less than the soil the detector is ground balanced for, so the detector often sees them as targets (sometimes they sound off as very loud, strong targets, but more often as moderate to faint). Like a metallic target, the larger and closer to the surface the hot rock is, the louder it will sound off on your detector. Hot rocks and mineralization cause many beginning prospectors to give up and decide that finding gold with a metal detector is impossible. This video shows how to deal with them.
