Now we are trying to upgrade the sluice because where we dredge we could find larger nuggets. Im thinking of placing a section with taller riffles like in the picture with the rails only going half way or 3/4 of the sluice and leaving the same size riffles or making it bit larger at the end of the box for the larger nuggets.

Was wondering what size a sluice for an 8" dredge is ideal. Keene uses a 10' on there mini 8" I believe. I was thinking a 10' x 2.5' but I'm not sure if that is long enough for optimal recovery. I was also thinking of ditching the 8" hose since its old and not too flexible and getting 30-40' of 6".

The part going unsaid is dredge manufacturers already reduce nozzle openings to less than the hose size. I can conceive of times when it may be advantageous to reduce the nozzle size further. Like in pure zero visibility blind dredging, perhaps. At the …

Since the sluice box in the 6-inch Precision was much wider than a normal Le Trap sluice, the prototype required quite a lot of work in a cut and paste project (using of 4 or 5 Le Traps) to create the first underlay recovery system for a dredge.

The size of a gold dredge (1.5 inch, 2 inch, etc.) is determined by the diameter of the suction hose— the larger diameter the hose, the more material can be processed. A floating gold dredge is essentially a floating sluicebox that uses an engine and pump to create a vacuum and send gravel (hopefully gold-bearing gravel!) into the sluice box ...

My question is why are all the manufactured dredge sluice boxes so short? The area we are dredging has pretty fine gold, with small nuggets to about 1/4" but that is about it (so far). So we have been researching the heck out of fine gold recovery and I think we will catch more with a longer sluice or series of sluices.

2.5" Dredge. This machine was a trend setter when it first came on the market and it continues to be one of our best sellers many years later. When other 2.5" dredges were floating on inner-tubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline 2.5" dredge sat on sturdy pontoons and used a power jet for dredge vacuum.

A 3" would be a better choice. The heaviest single part of a 3" dredge is the motor, and a 3" dredge can be sufficiently powered by a 5/5.5 hp motor. A 5/5.5 hp stationary motor is a small enough size to be easily carried by one man. Larger motors can be difficult to get into remote areas … especially for one person working alone.
