This is my brother in law. He is pushing me to buy a mark II or inphinity finder. Oh, i'm going there real soon! We will be finding treasures. We'll keep you all posted. Never thought this could become a profitable venture. As you can see, he has found bullets i have never seen, and i am in the guns hobby for many years. Also round bullets, maybe from the spanish american war, larger than a .45 cal bullet. Most of the rings he has found are 14k gold many of them with diamonds. Only one was recently appraised at $900.00. The finder has paid for itself. Everybody, there,s a treasure out there, go find it!
