At Orange and L.A. county beaches during the hot summer months, detectorists are all over those beaches like a bunch of cockroaches, but that that's only half of why less is being found, at least in the dry sand. For years beach rakes cleaned the sand and they only picked up the bigger items, leaving much still in the sand. Now many beaches use the sand sifter machines which pick up 95% of the recent drops in the top few inches of sand. A friend of mine talked to one of those drivers last summer, and just that morning the driver had found 6 gold rings just by watching what was going up the conveyer belt of his sifting machine. Those machines cover many times more ground, much faster, than any detectorist can. Those machines clean in the A.M. so the way to beat them, if your a dry sand hunter, is detect in the evening as late as you can. A person can do better in the water or when the tide goes out, in the wet. I'm a terrible metal detectorist who usually finds anywhere from a few cents to a couple of dollars when I go out, but this last Sunday and Monday something happened to me that has never happened before, and it relates to what we are talking about here. Sunday I was detecing the wet sand and get almost no signals, when finally I get a signal that was bouncing between nickle and the notch under nickle. I dug it up and there was a platinum ladies engagement ring with a diamond in the center and three diamond chips on each side. Monday at 4:30 A.M. I was at a differing beach. There were already 2 people doing down by the water, and 2 doing the wet sand up near the dry sand. I didn't see them get near each other in that middle area of the wet sand, so as they worked their way away from me I decided to see if there was anything in that gap they seemed to have left. During the first hour I was finding several pennies, 3 quarters, 4 dimes, then I got a nickle signal, which many times means a can tab. I scooped it up and it was another ladies engagement ring. This time it was 14k white gold with 3 main diamonds on top and 2 diamond chips on each side. The next day I took both rings to my local detector shop and they tested to see if the diamonds were real. They were real in both rings. I have talked to other detectorists and they are also finding quality rings lately. The bigger the beach, the hotter the weather, the more crowded it is, the more activity, people staying late and partying and drinking too much so they don't even realize when they have lost something, all make a difference in your chances.
