A nice fellow and his wife were vacationing here in Monterey, for his wife’s birthday weekend. The fellow went down to the water’s edge at Del Monte Beach, to wash off his kid’s sandy hands , in the ebbing surf. To rinse off his kids’ hands. As he did so, his ring slips off into the cold surf. But he was momentarily unaware of this. Then he went up to where the tidal zone meets the dry sand, and began to shake the water drops/sand off his own hands. And it was at that point he realized his ring was gone. He figured it must have « flung » when he’d made motions with his arms there.
I got the call and met him within 15 minutes on the beach. He showed me the suspected zone. But alas, nothing there. Then he casually mentioned how he’d been at the water’s edge for a brief moment with his kid. So we gave it a try further down there, and presto : There was the ring. Buried in the sand closer down towards the water.
Glad I could help. Thanx for the tip . 
Super cool of you to help so quickly and a great find for my brother. Thanks
