I have dug so many pull-tabs in the park near my home in the last few weeks I almost quit digging 20s an 22s. I almost didn't dig a 20 today but it was a good solid sound from 4 sides so I gave it a shot. It was down 6", layin in the bottom of the hole when I pulled out the plug. 1906 V. I couldn't believe my eyes when I saw it. My first one. Was using MXT with 950 coil, gain & disc on preset trigger center. Thanks for lookin, Ken
