..................Thinking about changing out the original nylon bolt and wing-nut to a stainless bolt and wing-nut!! (The coil flops somewhat!) Not real familiar with the BBS technology, SO IS THIS A GOOD IDEA OR NOT?? It doesn't effect much on single frequency detectors but again I have no experience withe the BBS technology!! Just wanted some good advise before heading out into unknown territory!!............THANKS...........Joe
