I went out today going over some old diggings. I managed to score 4 tiny bits total weight 0.2 grams. A friend of mine was there using his GP4500 with a 6 inch coiltek coil. I got a signal and before I dug it I called him over to see if he could pick it up with his machine. No it would not pick it up. The little nugget was about 2 inches down. I am really pleased with the performance of the Xterra. I was using the 6inch round hf coil. its a great combination. Seeya Neilo
