xterra70 and a gold ring ?

Out for 4 hours today, playing with the xterra70 I got from Chuck at Treasure Hut.

I am still on a huge learning curve. Today I was concentrating on solid repeatable signals and pinpointing.

Pull tabs were hitting a solid 18 on TID, however, this ring also hit a solid 18, the main difference between the two is the pull tabs had a bouncing TID in the pinpoint mode, the ring was varying very little.

The ring is unmarked and feels a bit light, so my guess is gold plated.
