Was in a city park today with my MXT Pro and had the 5.3 coil on. Dug some nickels, dimes, but mostly Zincolns. None over 3" deep. Then I started heading out into an open area toward a huge Sycamore tree. Wasn't really swinging , but the coil was close to the ground. I'm very new to detecting , but the beep I heard just sounded interesting. The detector said 7" deep. I finally pulled the class ring out at about 9". I don't believe in luck, but there couldn't have been that much skill involved. I was pumped. When I become less technically challenged I'll learn how to use my new digital camera and then learn how to post some of my finds. I'm finding my new ProPointer to be invaluable. It has cut recovery time in half at least.
