I am wondering if anyone else has had this experience, I was detecting in a pasture thats supposed to be an old home stead, and my garrett ace 250 just started beeping like crazy and the display kept going all over from one end to the other, I even lifted it into the air away from the ground and it would not quit doing this erratic behavior. Hopefully someone else will know what this means. There were no power lines or anything around to cause this that I could tell.
