I cancelled plans to go water hunting, as they were predicting more rain with high winds. Instead, I hit a sports field sharing 3 x soccer fields plus an adjoining park. I worked this whole area for seven hours and was surprised at how much loot, jewellery there was plus a couple of silver coins. My knees were getting pretty sore by the time I finished. it rained a couple of times during the hunt, but not seriously enough to cancel the hunt. But those dang mosquitoes were a nuisance at times when the wind slowed down.
Here's the rings all polished up. The first one on the left was as flat as a pancake. I got it round again, but it got 2 x 3/4 tears in the process. The very last ring on the right was photographed using a timer on the camera, and while it was counting down, I steadied one of those common lasers at the stone to get that effect.
Below are the silver coins, a flat button and an undefinable found object.
