I am pretty sure there is a club in the area or within an hours drive. The reason I am pretty sure is the FMDAC held a convention there in 2007 and they always have a local club as the sponsor for the convention. Check out their website www.fmdac.org and go to the contact page and email the South Region President, Art DiFillpo, as he lives in SC.
FMDAC = Federation of Metal Detector and Archaeological Clubs
