In Vol 3 I compare E-Trac’s Auto vs Manual sensitivity on a deep target that turns out to be a Large Cent. I also find a really cool old buckle, and come across a Box Turtle. I use a Minelab E-trac, Garret Pro-pointer, Lesche Model 80T Relic Pro Shovel and a Veho Muvi mini Camcorder. See forum.treasurenet.com for more of my finds related to my hunting area.
