Still very new to metal detecting.... I have a 4 or 5 month AT Pro I took to park today. Took it out, turned it on, ground balanced, and then it started going nuts. I put the coil on the ground and the numbers and tones were rapid fire. 2 to 3 signals a second. Turned it off, took the batteries out, turned back on and still with the crazy tones. Uncoiled the coil wire and re-wrapped it. Did not work. I then wrapped the coil under the shaft on the first wrap and it stopped. I tried moving the wire around and no more weird tones. Did not have time to re-wrap over the shaft, will try when I get home.
Any thoughts?
