Hey Guy! Just goes to show ya, your job loves you! lol. Can't stay away from that electricity! Glad you're okay man. I can give you some tips on the pin pointing and the large iron problem. If it's larger than a nail, tye Minelab will give a somewhat positive signal, but when you pin point, the signal is off to the side somewhere. I use that as a guide to know that what I have is iron, and make the decision wheather to dig or not. Remember, the pin pointing is a hot linier "strip," from 12:00 to 6:00. Work your way backward to forward. Where the signal just ends is the edge of the target. I'll try to send you some info. Talk to you soon. Darryl
