I took some of my smallest 14 and 10 kt chains and earrings and one of my smallest 14kt crosses that will hit on my Ace 250 and everything will hit on my Shadow X5 in discriminate and wide open dis on Ace and put them up to the New probe. At the end of the probe it won't do anything, no beep or vibrate. Yet, if you put it to the side it will beep and vibrate on all my small stuff even the 14 kt diamond earrings and earring backs. so if you know it is out of the hole or even still in the hole you are going to have to use the side of the probe to get it to beep and vibrate. That is a good thing. :Thumbup: : : . OK later HH Back to Lurking. I do like the probe and will keep it. Jerry aka Tinfoil
