As you can tell from the video.... the customer is not happy with his current setup.  So we thought we'd post the fixes and recommendations here. It's kind of tough one to "fix" because of the notes below, but we'll do our best. 

Notes...
The system shown is fairly low gph so we have to use mats that are made for this. We can't use aggressive matting as the water is not DEEP enough and there isn't enough SPEED. 
The water coming off the header box drops DOWN... into the sluice. Unlike ours which SHOOTS in and clears out the top. This can cause PILE UPS under the header box. 
The sluice is fairly short... so we're limited as far as varying matting surfaces. 

All that being said........ I've watched the video over and over and over. My GUT is telling me to run alternating Motherlode and DownDraft all the way down. Then play with the pitches (extreme variances) and see what happens.

OK, fair enough. Should I run 1 of each then again one of each or what order do you recommend? I am all ears as anything has to be better than the set up I sent you above.

I would say one of each alternating all the way down. Also, you can do the TAPE ONLY method to test and then play with the arrangement of mats.

Another question.

 

What do you think about also putting a higher GPH pump on the tool?

I would first try that matting config with the same pump.

Do you figure that one strip of each should do it? It is tapered after all.

If it's 10" wide.... you'll get three pieces of each. 
Each is roughly... 6" 
So you will have about 34" - 35"

I think what Doc meant to say is that each factory delivered width of mat is long enough, about 3 feet, for three ten inch wide strips (crosswise to the water flow).  The mats are nominally six inches high (measured with the flow of water) and two full length mats (as shipped) will generate six segments for your box and that should cover about three feet (again, with the water flow) of sluice box bottom.

OK, I ordered the mats. Now the issue is that since they made the sluice with a taper, once I cut the mats to fit, they can not be put in a different order. (did I mention I have vast buyer's remorse?) So, if you were in my shoes, would you put the Motherlode or Downdraft first?  Or don't you think it really matters?

Mark if it was mine I would start with motherlode under the box where it drops down but that's me.

Well, I got everything cut and taped together for a test run. Ran about a gallon of paydirt (straight from the creek in AZ) and got nothing. I figure that after getting bounced around for 6 or 7000 miles the gold mat have worked its way to the bottom of the 5 gallon bucket.
