Hi All. I'm trying to find out if anyone has any suggestions on how to dig in a VERY hard ground. My uncle has a farm up in Wisconsin that I go to about 4 or 5 times a year. I will be heading up again in april. The ground that I mention is where all my relatives and visitors have always parked for,say...the last 50-60 years. I found an old photo of what the ground in this spot used to look like in 1920 and it was all grass. It's a pretty big spot, so I reason that at some point things were probably dropped on the ground there. Especially with all the cars that have parked in this area for the last 60 years. But as you can imagine now, where there used to be grass is now a very hard rocky type of ground. There does'nt seem to have been gravel actually dumped on it, or if there was the pieces are very, very small now. But last year when I briefly ran my detector over some this ground I got some good sounding signals about 3-5 inches down. I tried to dig the ground up but could barely make a dent in it with a screwdriver or regular shovel. Any suggestions on what i could try? Thanks All. Sincerely, Randy
