Hi, I'm new around here and know you guys have posted heaps on smaller coils etc etc. The success I've had with smaller coils on all my detectors, not just the X Terra, is really great. Lowering the sensitivity and slowing down the swing speed leads to increased finds of what others have missed. I guess I'm not telling most of you anything that you dont already know, but maybe a newbie (like myself) can pick up a pint without going back through all the posts. Looking forward to sharing experiences etc. instead of just reading. HH Sapper.
