Steve, you seem to have access to both metal detectors. Is there any chance of you trying the M6 stock coil on the MXT and put the results on the MXT forum? I am curious as others are, that by doing this, would the MXT operate better or any different than the stock 9 inch coil that comes with the MXT (which personally, I don't really care for too much). If they are interchangeable, how does the stock 9 inch MXT coil work on the M6 and how does the stock M6 coil work on the MXT or is there any difference at all? Thanks for your time and answer if you come up with one. Thanks again!
