When i hear a high pitched beep thunk while detecting I assume it is an iron object. I hunt in iron mask -6, fast mode, disc. 26. While hunting a very old park i was getting a lot of high coin thunking but finding very few coins (it has been hunted to death). I was getting frustrated so I dug one of these signals and up came a seated dime, other beep thunks turned out to be indian heads, wheaties and mercs as well. Some of the dimes were barely audible chirping sounds. Also these were not repeatable from another direction, only one direction. This could not be a fluke because i found over 15 coins this way. So what is this beep thunk ???
