Anyone have any ideal if this type of setup really works.

LaTrap is a drop riffle sluice, and they work very good in that application. But I'm afraid it wouldn't do so well as a dredge. Keene for example, you have to change the riffles when going from a sluice to a dredge, because you're running more material through it. The put riffles in that have a longer leg on the top will hold more material, and handle a larger volume of water. With LaTrap you don't have that option because it's a drop riffle. I'm guessing there's still a grizzly in the hopper and that will help. The first thing you need to do is take it out to the creek, and see what it does, my guess is the riffles will load up and you'll spend more time than necessary doing clean ups. If that happens I'd put some expanded metal, and bend the edges down to use as legs. Hold it about an inch or so over the riffles, and then try it again. That will classify the material again, and keep it out of the riffles so the drop riffle have a chance to work the way they were designed.
make sure your small pump puts out enough pressure not just gpm. i would reconfigure the header box so it would discharge material straight down into the sluice. the problem being is the la trap is small lenght wise.
link to discussion That was a thread I started some time ago asking pretty much the same thing. May or may not help answer some of your questions. It should work for you if you set it up right... I would do plenty of research on the orifice and pressure hose sizes for your jet or nozzle. Will make or break you if you don't.
In the end the cost of that pump put me off the idea... saved my money and continued using my Harbor Freight 2 inch pump. In the mean time I rebuilt a 50$ minibike and made a custom trailer to tow all my gear with it.
Ended up going with a larger dredge and pump... where there is a will there is a way to get it in the water.
the sluice works I have used one but I was using it as part of a clean out sluice though over at a friends .never tried it for the creek . but we ran about 3-5 gallon buckets down the line before clean out .we had it on about a about a 8 degree line
Will a 2 inch Honda backpack dredge pump, pump enough water to make it run right?????????????? Or what would you use. Weight is what I'm need to really cut down on. I have no help here toting things. LOL more gold for me... Hehehehehe.
