Hey Doc, just watched your latest videos where your running the Raptor & the multi sluce. I have a question about the multi. You recommend using a 1100gph pump for this unit after classifing down to a 1/4" at an 11° angle . Now in the video you are running a 2200gph pump & not classifing your cons. So my question is what angle did you run the multi while doing this? Still 11° or a more aggressive pitch?
Thanks....!!

We show this in another video as well.
It's the "field set up" if you want to run as a primary recovery unit in the field.
The LONG hose... 11 feet, and the LIFT... take it down to probably 1500 true gph at the unit.
Pitch was 11 degrees.
The slightly high gph allows for larger rocks to flow through.
Many of the rocks were over 1/2" as we didn't classify.
There is RANGE of gph that won't greatly impact the recovery.

I must have missed that other vid. About the "field set up", I did notice the longer hose. I have a few spots I wanted to test, so I figured the multi would be perfect for that. And if I don't have to spend time classifing I'll be able to move a lil faster... thanks ...!!

Hey Doc, I had a different question...wondering if you think same mats run in a 10" sluice with an 1100 gph pump would do just as well? I can't really afford the Multi Sluice at the moment, and have a 10" one that just sits there after buying the Gold Hog Excavator Mini Highbanker, and Hog Pan! So anyway, would like to purchase the mats, if I knew what I needed and the configuration? Thanks for the help!

Kind of...... but you lose the action of the header box which is kind of critical and you really have to match the flow to each match. 1100 gph for the 1st mat, and then 800 gph for the washer mat. Now, that's in an eight inch wide sluice. So you have to do that math for a 10".

Here is a picture Doc posted showing kinda the relationship of amount of water in different width sluices. Gallons per hour divided by width equals gallons per inch per hour. So in this example 5000 GPH divided by 10 inch sluice = 500 GPH per inch width. Yet the same 5000 GPH in a 14 inch box would only be about 357 GPH per inch width, making the water height lower and the velocity lower. :roll: :? . Ok had to re-read that twice but I think its right.

I have a related question for Doc. If running the Multisluice as a field unit with a 2200gph pump, I assume that the cons from those runs should be then run with the 1100gph like normal. That is I should then run the three step process. Also, have you tried using a 1" gas powered pump in the field? I am thinking about buying the little pump from Harbor Freight and using it instead of lugging a big battery in. I thought I could adjust the RPM of the pump if necessary. They say it is a 2250gph pump. What are your thoughts? Thanks!
