The two small objects i put on the dime to let you know that the 6" ex coil will pick up small objects, like the button at 5" and the piece of a ring at 4". Coin mode and relic mode sen 7 discrimination 6,threshold just slight. Pounded site. Weather getting cold. I need to find some new sites. But like i say the coil usually will always pick up something different like the button and the piece of jewelry. The coins vary in depth from 2" to 7". The dates are ranging from 2000 to early 1970s. Thanks for looking.
