I just rec'd my new Fors CoRe on Monday and have been playing in my own yard so tonight I felt confident enough to try it out at our local high school. There's an older ball field and track so I gave her a whirl. At first the signals were kinda tough but after just a few minutes I was digging coins no problem. I was using the large stock coil and had no problem determining multiple signals. This machine is phenomenal at target separation in trashy environments. There's one area that was built up a few years ago with some fill dirt after an older home had been razed so I was lucky enough to pick out one goodie in the trash.....a 1901 Barber dime!!!! on the first trip out the Nokta got some silver!!!! I was impressed to say the least. Can't wait until I really figure this thing out....
