The cable on my 6X8 sef coil is all stretched out and I have a heck of a time getting it inside the shafts. I ended up with this loop in the cable trying to adjust everything shorter. Is the loop a bad thing or does it affect the way it works at all. I have found some fairly deep junk with it but I threw one of my silver rings in a 3" deep hole and checked it and it wouldn't hit on it except with the very tip of the coil. I'd say maybe the top 2". When I swung right over the top of it I got nothing. Needless to say this worries me as I could be walking right over a lot of good targets. Any help would be greatly appreciated. Thanks All, Tony
