Back in 78 when I and a friend were taking lessons, one of the gals lost an ear ring in the pool. She had no idea when or exactly where. I found it in about 15 minutes.Apparently I'm the only one around here unfamiliar wish SCUBA diving. The fact that she lost it or how she lost it is not that interesting to me. What I find fascinating is how a tiny, tiny object could actually be found. Even a haystack is pretty small compared to a huge lake. But a tiny ring compared to a massive lake that is acres in size?! Finding an object in a larger object that is trillions of times larger than it is no small feat, in my opinion.
It gets weirder. Three months later the same friend and some others went camping at a lake for the weekend. I showed up later. They had to go back in town to buy a new weight belt that slipped off one of divers waist without him noticing. Again, no idea when or exactly where. I wasn't in the lake more than 25 minutes on the surface looking down in about 15 ft of water. I saw something and dove down. Yep, I found it! Now consider that I wear glasses and my mask didn't have corrective lenses on it. Very odd!
