A few days back I believe I mentioned that all of a sudden in the middle of a hunt the 10" coil went bonkers and then wouldn't ground grab balance. It would go to 82 when turned on, but would never ground grab balance. I finally got around today to pack it up and send it back, but decided before I called FT to try it one more time. Yes, it g g balanced perfectly. Did the balancing act four or five times and had no problems. Anybody have any thoughts on this? Obviously, I am a little leery since it wouldn't g g balance two days in a row when trying it after it initially wouldn't. I will say that the morning it first happened that everything was really wet and damp. I had had the coil wet before and had no problems, however. I am going to start using the 10" again, so will see. Thanks, HH jim tn
