I got a break today so I grabbed the new X70 and went to a local park. As luck would have it, it started raining so I had to stop early. I dug a few zinc pennies, quarters, bottle tops and lots of aluminum slaw. I sure do like the way it locks on a VDI and holds it there. My DFX hardly ever done that. I have a question on ground balance, when I finish the procedure it gives me a number say 36. What does this number stand for and does it tell you how mineralized the ground is?? If so, can someone tell me what kind of ground I have? I cant wait to get back out and try it some more, I already like it more than the DFX. I had fun not hav ing to worry about adjusting everything for a change!!!!
