I've heard a lot of people say they never found anything. A couple showed up, started probing for gravel pockets, right around my rock collecting spot. Then I found out from them, someone had just come by my spot, found a diamond. My eyes aren't all that good for small stuff, still able (so far) to get through eye examination when renewing the drivers license. I didn't feel like screening all that dirt to find diamonds. I guess the gravel idea, is a good way to do it. You take a probe to check for gravel. Find a pocket of just gravel, scoop it out, process only gravel, pick out the diamonds. Next time I'll have to do that, even could haul back some gravel too! Takes a trip there just to learn what is the productive method.
