Thanks for the replies guys. To be honest most of the coins were only 6-7 inches. All the dimes had trash "pull tab, screw cap, foil" above or close to them. Because of that the signal and numbers bounced a bit and most would have kept going. I not only dug allot of coins that day but allot of trash to. I upgraded my diggers, one is a t handle Samson and the other is the raptor by Predator's tools. Good diggers makes a huge difference.
