First, High Plains Prospectors are a dream to work with. Second, this was my first big-boy sluice purchase, and while testing it out in 'the lab' using the mini-mat I picked up some gold flakes in the tailings I was using for testing. I tried several different pitch and water flow rates and recovered the same bits of gold each time, so it seems very forgiving, and very effective. I haven't used it in the river yet as it's still a bit cold up north here. But I have no doubt it will prove quite durable. It is very nicely constructed.
