Just like a Jackrabbit! I kind of figured it may be due to several things, 1- I am not tuned in for the right conditions, although I ground balanced, the semi frozen ground may be shifting or distorting the signals. 2. This machine is very sensitive and I may be picking up small bits of junk that are nearby but small enough not to register on their own, just hitchin a ride with a good signal 3. my settings are incorrect for the ground although I ground balanced. 4. coin or object is at a weird angle
This is why when I popped that dime out I was utterly shocked because I was not expecting a dime. The detector did give a few mid to high tones, but then again she said she was foil. So when I got it out I put it on the frozen grass and played with the knobs until it rang true and sounded good. Those numbers I posted earlier were what evened things out. After that I got very little falsing and after digging quite a few "blind holes" before I made those changes, those "blind-empty holes" practically went away. Now the F5 acts almost identical to my XLT regarding pinpointing, If the signal is loud and strong while in motion but when the pinpoint button is pressed and I cant seem to find it, then it's a halo effect or junk. Thats the way it appears to me so far....but I've only had limited experience with this machine
