These bags, as everybody already knows, are as described!
I was a first time gold panner when I placed this order, and I managed to recover at least 100% ROI (it's tough to say the exact amount because I still have some black sand specs in my jar). Considering I'm not a very patient panner, and it was my first time, I probably missed some gold.
I got a bag of the superstition mountain 100% ROI and a bag of the lynx creek 100% ROI. I know the S. Mountain bags are described as the easiest to pan, but I preferred the Lynx creek panning experience. This is mostly due to the lesser amount of small stones to sort in the Lynx Creek bags. I use a 5lb magnet to sift through the material before panning, so I never had a problem with a ton of magnetic sand covering the gold in the pan. The gold seemed like smaller sized flakes, again I'm a noob, but they were large and heavy enough to make panning the black sand out fairly easy. I prefer using a pan that has a smooth area on it, works great for getting the sand out and not hung up on grooves, like I said the gold is heavy enough to not get washed out by the wave movements. Just be careful!
