I got out yesterday to a local lake that is highly alkaline. Had an enjoyable afternoon wading around swinging the Sand Shark and although the signals were very few and far apart I did manage to dig 3 very crusty old silver rings by digging signals that I wasn't sure were even there at first.
Here's the loot for the day...
And a shot of the rings before and after cleaning them up..
