A lot of detectors have difficultly with gold chains because they see only the surface of the links and do not add the up any links to make a mass, the Sov GT included. Silver being more conductive can be easier to respond. Many hunters get upset and swear that their detector can find gold chains without taking into effect the size of the clasp or any pendants or even if some coin was near the chain. Time spent searching for these tiny, scratchy signals can better be spent looking for the "Round" signal. Course when I am bored I tend to dig bird shot signals..
