I went out for about 3 hours this afternoon. I ran the 600 in field one and sensitivity at 21. I ended up with 9 coins out of the field and one was a 1918 D mercury dime. It was about 6" but it was tilted in the dirt. The VDI bounced around from 20-28. There was one Indian head in the bunch. The rest were green wheat pennies. I am tired but my arm isn't sore like it is using my Explorer SE. I would call that a good first field outing! Good luck and HH!
