Went to a different beach today, where there was no interferance from mineralization. Found the usual change, junk jewelry, etc. Then found a 14k bracelet. First time I've seen real gold in the scoop in years! Took the bracelet by a jewelry store to get it repaired as a Christmas gift for wife. A friend went with me, and he was using an Equinox 800. The Tesoro whooped the Nox, but he's still learning his machine. Fun day!
