I was finally able to get out this morning and darned if I didn't get that Hibernia signal on the absolute first swing! If only it was near a cellar hole where I would have had thoughts of the site never being detected. But it was 20 yrds from where I parked, a good quarter mile from the hole. So was just dumb luck.
I turned the machine on, ground balanced, and bang! I once dug a play money nickel after a few swings. Thanks! (I guess I can't edit the typo in the title)
