That's a great idea for the headphone cord. Chris is right on about no overload on small gold and I've yet to actually find big gold so I'm hoping to verify that soon. I do dig every target just in case and have a lot of lead nuggets and various other bits of wire, boot tacks and other metal frags to be sure, but I know eventually that screamer will be a big one as long as I keep at it. Good luck and happy hunting with the new toy.
