Made a hunt today at an old spot of mine that I have been hunting for sometime now..My little brother came with me he is just getting started in metal detector. The hunt started out with a deep signal 11 1/4 inches the VDI's were all over so I passed because I got another hit and the VDIs were steady and sure enough a quarter at 6 inches 1963 ..TThe day went on with some pulltabs some clad, four silver dimes between me and my brother..We were heading back to the car to go grab some lunch and I remembered where I got that signal so I went over it again and it was the same with the VDI numbers I told my little brother give me a minute let me dig this one so he walked over so I cut me a plug and started to dig and dig I told him put the pointer in a hole off it went and he pulled out what he thought was a dabloon he started to wipe it off and it was a silver dollar 1921 my third one since I've been metal detecting... I learned a valuable lesson did all deep target's. ..He is hooked as well on MDing... The worst of it so not the first time I pass a target because the VDI's were all over.. when in doubt I'll definitely digg from here on out.
