I've been playing with the "Magic" program on the V3i, and I cranked the gain up to 9 today and started finding old coins deep, in an area I've hit before. Everything was 6-9" deep. I found 7 wheats, 1x 1923 buffalo, a 1896 Indian head penny, a silver Shriners pin, a gold plated cuff link, and lots of misc. Here's the link of the Barber dime I dug, on my youtube page video. Go get you some! Be sure to watch it in HD https://www.youtube.com/watch?v=3n1htxLrBzY
