Under flow sluice ?
Has anyone bought and used one of the Under Flow sluice being sold by X Grumpy Prospector? If so, what do you think of it. I am considering buying one in the spring but being that money is tight i don't want to waste it on something that doesn't work any better than a standard Keene or Joe type sluice. Appreciate any info. Thanks.

I have not tried his but I have tried a gold trap sluice (and own it.)
I bought a Bazooka Gold Trap sluice which does not need to have the material classified.
I like it, its a good box that got a lot of micro gold along with the larger stuff.
Here is a video of the first time I used it, just 1 5gal bucket from cleaning cracks, you can see how well it did.

any peice of equipment is only as good as the operator! they all work!

a couple drops of dish washing soap, is all you need to break the surface tension of the water.
Actually any kind of soap should work. Good post, Good Luck.
Two rules in life: Don't sweat the small stuff.
It's all small stuff.

NO SOAP NEVER EVER AS IT FLOATS GOLD FOR GODS SAKE- jet dry is the surfactant you want to use as it releases oxygen and tightens up the surface tension for better recovery. Just google a floatation cell to see why NO SOAP-even if told so by the pope as gospel-John

Ok, i checked out the Bazooka Gold Trap and it does sound interesting. But are either of them any better than a standard sluice for the average person?

I have bought a little thing of Jet-Dry since that video.
The Bazooka is better in that you do not have to classify first.
The Bazooka is worse in that you lose any nuggets over 1/2" in size.
The Bazooka is better in how quick the initial cleanup is.
The Bazooka is worse in how long the following cleanup of the cons takes.
The Bazooka also needs more water flow.
Chip (Miners Cache owner here in Redding) had a friend of his use it with a regular sluice behind it, his friend isnt back with the results yet but he will let me know how it did when he gets back.
In the long run of things, the Bazooka is quicker but you lose larger nuggets and specimens that a normal sluice would catch.
From what I hear they are working on a nugget catcher attachment though.

Thanks Neo. Not many nuggets at all around here, let alone over 1/2", so no problem in that respect. I have a large free standing classifier so classifying don't take any longer that shoveling into a bucket would. So that isn't an issue either. So in the long run i guess i just keep on using the sluice i have. Thanks for the info though.

I can dig it! "WP"
Do you have a photo of the large free standing classifier?
Sounds interesting and I'm always on the lookout for classifying ideas.
I have a bazooka style sluice that I use in certain situations and it works great as a time saver as long as the water is running fast enough to properly supply the fluid bed.
Usually I dig right next to where I set it up close to the bank and dump the material right onto it using my scoop shovel. Once that area is finished I'll move the sluice and start over.
Clean up is a breeze..... just a few dunks into a half full 5 gal bucket of water and it's clean.
My scoop shovel can be used right in the creek ....

If i did this right here are pics of the free standing classifier as well as the shovel i had a friend weld up for me. Works great in water and out.

Thanks. Yea, they both simplify things. I am thinking about modifying the classifier by putting the 1/2" screen one one side and then a 1/4" on the other side of the 2x4 and run the stuff over 1/2" off the end since there is not a piece of gold in this area that big, and then putting a bucket at the end of the 1/4" screen and catching the stuff between 1/4" and 1/2" and then checking it out with a metal detector and a separate bucket under the vinyl to catch the under 1/4" to run through the sluice. Hope this made some sense to you.

How does it do? Do you think it is any better than a standard normal sluice? Here are a few pics of the cheapy home made highbanker i just finished. What did you use to funnel the water in?

It's better in some ways but I still use my modified Keene A-52 on my highbanker and trommel and 2" dredge.

Great job on the Highbanker!
