I just want to let people know to be careful if your digging tool has a metal handle. I was digging in my driveway with a small pickaxe and hit a power line. I found the pickaxe at the dump. It did not have a handle I started to weld a metal handle to it but I changed my mine and made a handle out of a piece of red oak. I sure am glad that I went with wood if I had went with metal I would not be posting this. That big ball of green fire got my attention. I got my detector and went to the house. That was enough detecting for the day.
