    Are any of the folding sluice boxes any good? I've heard of them folding on you when you don't want them to and that they can leak fine gold at the joints even if the overlap is the first section fitting into the next and so forth. Has anyone tried, or is currently using, one that can shed some light on the subject for me.

    Ya! What's the deal? Anyone know "Jobe" v.s. "Keene" v.s. "Royal" i.e.??? No sales reps please. Durability, hinges, metal gauge. Big THANKS for any experience regarding this. OR is a 2-3' model really the only way to go.

    I have a Jobe folding stream sluice, best thing I can say about it is that it folds and fits into a five gallon bucket. While its weight is slightly more than expected, its good for packing in, great for storage, and vehicle transport. Durable enough, works on par as far as recovery is concerned. While it never folded and pinched my fingers this sluice uses wing nuts to tighten bolts in the bottom of the sluice to hold the pieces straight, they can be a little difficult to hand tighten enough to keep all of the curve out when you set it in the stream. Came with 2 steel riffles, 2 pieces of expanded metal, and two sections of ribbed carpet. Has v mat applied to the top section before the riffles. The folding sluice requires a modular approach to the riffles, due to its folding. This provides an unexpected benefit, I can run one, both sets, no riffles or just the expanded and carpet, or half riffles and half expanded depending on water flow, and alternate top and bottom.

    I have a Royal Folder.
    I swapped out the all the riffles and expanded metal and miners moss with Gold Hog matting.
    The times I have used it out in the field, it has done well and captured the gold.
    It did not fold up on my unintentionally at all, and was standard set-up with a sluice that size.

    As far as loosing gold at the hinge points/overlaps.....who knows.
    But for me that minimal amount - if any - I do not loose sleep over.

    This unit is now used as a recirculating system at home.
    I was a Bazooka Sniper in the field now.

    Hope this helps.

    I have the Jobe. I could never get it tuned properly or straight in the stream. Always looked like a W. The flare would bend down into the water. The wingnuts, being in the current flow, disrupted it. The water always shot up from the first riffle to the third. I have since popped out the screws for the wingnuts, taped the 2 for the riffles and flipped the 2 at the joints, swapped matting, riffles and expanded metal for Gold Hog matting and bought a stand. Now it works well.

    The Keene worked for me just as good as my one piece Jobe. I do have to sometimes work a bit harder to get it set straight because the joints make it appear curved. Also, I put the wingnuts on the outside to keep them out of the way of the water flow.

         I also have the Jobe Folding Sluice box. The first modifications were drilling holes on the sides and adding bolts when it's open. I never heard of them collapsing but they sag like a happy face.

       The other major problem is...You need to classify to 1/4" because...When it loads up with 1/2" rocks, the riffles stay loaded up...So people run them too fast which loses the Gold. So slow it down until it slowly moves the material.

       About the rooster tails...I set the wing nuts straight with the flow.

       Like others said, I like it because it fits in a back pack, but it's heavy. Everyone else I know uses the light weight green le trap box.

    I say, drill some additional holes in both ends where they hinge and use round headed carriage bolts on the inside with the wing nuts on the outside.

    I have a Royal and I do like the portability. I have never had any problem with sagging or folding. The wingnuts seem to fit tightly and hold everything together nicely. I agree that putting the wingnuts on the outside helps. I, too, noticed the rooster tail from the first to the third riffle. I recently read an article in an old prospecting magazine that said this means you do not have enough water flowing through your sluice. Not water speed, but water depth. The water flowing through the sluice should be deep enough that it runs fairly evenly over the riffles. Then adjust angle or speed (using a wing dam, etc.) to get your flow set right. I will be trying it out on Friday to see if I have better results. Hope this helps.
