Nice find,
I am new to the forum and to Metal Detecting, I bought a Ace 250 also. I have not found to much, just some newer coins and alot of junk but I am still learning the detector. But my wife took it out and found a silver chain about 6 inches deep and some change the first time she used it. I just need the time to get out more.
Nice to meet you all.
