Went to the park today where I lost my VibraProbe two days ago. Brought the pin pointer I made two years ago from a stud finder. Used it today first time and I'll be darned, I like it better than the VibraProbe! I can hear it with headphones on and can feel a vibration too. And I have the advantage of adjusting the sensitivity. Found the heavy sterling chain (Italy 925) just before I was ready to quit and a Cross pen and a junk ring along with the usual clad. The chain discriminated out on my Vaquero at the same point where a zink penny is knocked out, good thing I dug it. Usually I don't dig if I think its a penny. Guess all signals should be dug. Wonder how many silver rings I walked away from.
