It's been about 10 years since I've done any detecting and I'm about to start again. I've still got my old Radio Shack Discover 1000 (Tracker IV clone with a cheap coil), but I've decided to get a new Tesoro Compadre, which is on the way from Kellyco. Can I expect a big difference with the Compadre? I like to search school parks, mostly built in the 50's to 70's. I normally just find a lot of clad coins at the surface or maybe 2 or 3 inches deep. The only good finds I have ever come across was a mercury dime found at an older school at about 4 inches and a couple of small pieces of jewelry such as a silver St. Christophers medal. The ground around here is mainly hard dry clay/dirt. Do you think the Compadre will have noticeably better performance?
