Digging in the woods behind my office--80-100 yr old trees. No signs of previous habitation ( foundations etc...). Got a 01-46 reading about 4 feet from an old mulberry tree. I dug down about 8 inches and hit a very large root. I am close as my sun-ray pinpointer detects the target with ease. Trouble is I have to return with an ax and shovel to finish the excavation. I am not familiar with digging a number such as this. Anyone care to venture a guess---I am not a relic hunter so maybe this number is common???? It is a solid 01-46 with an occasional jump to 01-47-----there is no bouncing around of the numbers. Guess away---I am interested in what you have encountered in the past with these numbers! Thanks-----I will post my find as soon as retrieval is completed. HH---Boog
