I see in another post that you fixed your issue by pulling back the strain relief and reconnecting/repairing the frayed wire. I too had this issue with my X-1 this summer, and I too had barely owned mine for a year. The problem actually started happening shortly into my first year of ownership. However, it was very infrequent and seemed to have to do with the humidity. Also, I swear I will never hunt without my X-1. I can't stant pinpointing with a non-descriminating pinpointer, I feel blind. Plus the depth of the X-1 with even 20 or so sensitivity is well close to 3 inches.
Anyway, eventually it got worse and worse to the point where any slight movement set the probe off. Of course I was an idiot and waited until about a month after the 1 year warrantee expired before it got to be too much for me. I sent it back and they replaced the coil and the cord. This was back in early July. The area where the cord goes into the probe and the switch is where it usually frays and the advice I received was try not to let that twist, and definately don't tighten them if they seem loose. I'm a bit concerned because the last time I was out, I was getting a little bit of that over sensitive can't jiggle it too much affect again. I have been very careful to try not to twist it, but taking it out and putting it back into the holder, it's hard to keep track which way to put it in without twisting. I am going to mark each of the strain reliefs to make sure it's not twisting. It's going to miff me if the probe lasts only a year before a wire frays, but I will be sure to return it under warranty. (if a part is replaced, it receives the 1 year warranty)
Talking with Ralph this has happend to others, though it doesn't seem to be everyone. It's interesting that you and I have owned ours approximately the same amount of time, perhaps a bad batch was received? (or many us CT hunters just hunt in extreme conditions!)
Glad you were able to resolve your issue, I thought I would post anyway and share my story. I still think it's the best thing since sliced bread, but perhaps something needs to be done to address these stress points and their durability.
