Last night I spent 3 hrs. detecting before I finally found a keeper. I pulled out a 1902 Barber quarter in the dark and my batteries were going dead as the Exploreer XS was beeping. Also found was the 65 Canadian penny. Tonight I had to use my old Minelab Sov. since my arm cuff broke on the Exp. last night. I managed to find the little silver ring and the two bullets with the Sov. I have no idea what this tooth is from. I found it laying on top of the ground where there was dirt work done.
