You can also try: Removing the carpet and putting down deep v matting then miners moss on top followed by the screen and riffle tray. It tends to catch the fines more then the carpet.
I always like to pan some of the tailings to make sure I am not loseing any gold ...and if it is real fine gold you might want to try some vortex matting
One more thing. If you dont see gold on your rubber mat right away, like your expecting from bearing gravels, slowly lift the head end up out of the water, and check for gold dust laying against the front edge of the rubber matt, in that teeny tiny corner. It can keep you from blowing a couple buckets of dust bearing material through, when you could have adjusted the box and caught it all.
Depends. What size gold is in the classified? If your pulling the little, almost 1/8" flakes about an inch and a half to two inches of buildup behind the riffles. If its all flour you can still catch it in the A52 but your going to have to work a little harder by running it flat or the tail up a tiny bit and let it build heavies till most of the wire plate is sanded in and then pull and rinse into a bucket very often. Not a full cleanup just rinsed clear. The A52 is capable of catching extra fine and flour if you do your part with matching angle to water volume and speed, and rinse and collect often. If you let it sand all the way in everything will flow out so stop and collect cons while one or two corrugated riffles are still showing between the large ones. I have used mine for years, and just now converted to a casluicebox model. The A52 will get a casluicebox highbanker add on head, and eventually an 1.5" dredge head and gear when its on "house money" and not mine.
Thank guys. I could see the material dancing around, and I classified to 1/4" is that close to ideal for this sluice? Also, have you found a good feed rate?
i have found slower the water the more the classification.....pan the big stuff with a big pan and run the fine stuff..garret super sluice cause any picker to nug will stay in that monster
1 inch per foot drop is ideal but not always possible in a stream setting the flow looks good ! Feeding your material through will tell you the fill story

I didn't see any gold on the black mat, I think I was losing some gold.

1/4 inch is where I classifie also but I keep watching my classifier for that 1 pound nugget Laughing here !
