    Keene A-52s sluice

    Has anyone seen or tried this new sluice? Can shovel into it with fast water or remove the screen section and hand feed for slow water.

    I saw a promotional video for it the other day I found it funny as the new features are mods that A52 owners have done for years.

    Decided to take sluice out to the neighborhood creek to give it a quick trial run to get a feel for it. Put about 20 shovel-fulls into it. The sluice definitely needs sufficient forceful flow to get oversize up and over the punch plate and out of the last section of the box. It will catch fine scaly gold.

    That 20 pound monstrosity is why I dont buy Keene gear haha. Other competing companies will come out with their own model to copy it but it will have 30 different mats and they will add an engine or whatever.

    Haven't had a chance to see one in action. A friend of mine just purchased one for a raffle prize for his club. I was with him when he picked it up saturday after we got done mining. My first thought was I have to get one of those kits for my sluice. After we parted ways and I was driving home, I reflected on a conversation we had earlier that day with one of our green members of our club. My friend an I were both using larger drop riffle sluices that day. Both of us commented on how nice it was to be able to clean our sluice into a bucket in ten seconds and how cleaning out an A52 takes 5-10 minutes. Now add that kit on top of it, probably 15 minutes to clean out. No thanks. I would rather see someone come up with a drop in plastic drop riffle modification for the A52. Hell, maybe I'll do it.

    I like wooden drop riffles. A eight foot 1x8 or 1x10, a circular saw, a square, a couple screws and you can make a four foot drop riffle likitty split.

    That old sluice has probably seen a good bit of material run in its day..... Not to mention gold too.

    A52s second trial run: wanted to find a place that would have the water force and flow to move the oversize material up and over punch plate and through the sluice without being pushed along by hand. Took the unit out to a small stream, and located a steam bed area with a 15 degree decline. Placed the sluice at the bottom of the slope. Let the water cascade into the flare. Shoveled bank run material into the sluice. There was enough force and flow under these conditions, that the oversize material was washed up and over the punch plate and out of the sluice. There was just a small amount of fine flour gold in the source material and it was retained by the sluice. The retention was made further down the sluice. Ribbed rubber matting was pretty clean; only one speck of gold was found there. Most of the heavies were found in the carpeted area under the thick expanded metal section. Lots of black sand in the Hungarian riffle section.
