Dredging with a 2" Keens

[Flintstone]

Hi all, I have a Keens 2" dredge, and a 3" Keens Highbanker dredge combo. I use the 2'" most because where I go it is easer to get to the water, the 3" about kills me. I have a bad back anyway. What I was think that the gold I get is small gold, would it get better gold if I put the 3" sluice on the 2" floats to get the small gold. The 2" has a Honda and I never run it wide open, so if I put the 3" sluice and run faster will hold small gold better? Just a idea that I had for this year dredging. Let me know what you think. Thanks flintstone

Not sure but the 3 inch might need more water flow than your engine can pump.
My thoughts are... Attach the 3 inch to the end of your 2 inch sluice box. After running the dredge and doing your cleanup see if there is any fine gold caught in the 3 inch sluice. If not... then you are successfully catching the fines in your 2 inch set up. You could also run the engine faster and see again if any fine gold is being caught. If not then just stick with your original setup.
I tested this similar scenario on my 4 inch dredge with a hand held sluice attached to the back and found no additional gold meaning none was being lost out the back.
