Trying to pack my ctx for a trip and the coil rod is to long for the bag, even on the diagonal. Now, I know I can buy a bigger bag but they can be pretty expensive. So, what would happen if I cut 2 or 3 inches off the back end of the rod? I would lose the guide at the end of the rod, but is it really needed? All the other detectors I have had just had a straight shaft, no guide. I know the shaft will spin 360
