I just got the V3 and tried it out in a park. I got good solid signal but when I used the analyze function the probability % was very low. So rather than do a lot of hard digging, I took it to the beach. Same thing, but it was easy digging, dug up a lot of clad. Ok, so today, I took it out in the driveway where I air test all the detectors (had a few lately) Laid out a gold ring, thank you Excalibur II, penny, quarter, dime, nickel, and a sterling cross. Each one showed the proper target but the analyze screen was giving probability reading between 2-30% and the graph at times was laid out flat. If I pulled the toggle back and then tried analyze again sometimes the graph would be better for the same coin?
