This is an updated flyer on the new A52S sluice and all the options and upgrades available for it. This also shows the new MAX12 high banker. The flyers are not finished just yet I have to proofread them and add some further details. I figured some information is better than none. ... See MoreSee Less

How do I get one of these flyers when they are finished? I just bought a A52S and need some accessories.

So when will the high banker box come in for the A52S. CHA been back ordered?

have a lot of toys and no time to use them lol

Can you guys send 2 inch backpack dredge to Australia

It’s been a while.
I finally started prospecting with the dredge.
Took a long time to obtain the license.
It’s a wonderful machine the super Max 6inch.
It’s working well in the remote waters of Sierra Leone.
Easy to transport to remote areas and assemble on the spot.
The diving gear is great.
I have dived myself now for some days.
It’s a great experience.

Have the sluice. Do you just sell the Hopper?

James Kendrick

It doesn’t matter how much dirt it can take if the capture system is terrible, miracle mat is the worst, you should team up with dream mat guys it would be fool proof then

Nice! I have the A52s already. Do you sell the washer section separately? What do you get for it including the pumps? How much of a waiting list is there?

Looks awesome. What’s the total gph on the pumps?

Y’all make this hard to resist. Really hard.

One pump kills a battery in no time. I can't imagine running two

Looks awesome. I was wandering what is the best degree⁰ (angle) to run the A52s with clean up mat?

Be nice if the high banker wouldn’t be on BO ,,,waiting !

My rendition I put together in 2019.

Cost?

😎☠💛

This is a comment we had come from a customer that just purchased a New A52S.
Tony Put my new A52S in the water for the first time the past couple of days. Can't believe how well it works. Never used a sluice box before, but was able to get the A52S up and running in just a few minutes (watched this video a few times beforehand). Mostly very fine gold in the river I'm working, but it's catching it. I panned each mat separately for the first couple of cleanouts just to see where the gold was being caught. Didn't find any past the first two permanently attached mats. I thought long and hard about buying a less expensive sluice box, but I'm glad I decided to go with this one. No classifying, just shovel the material in. Definitely a big step up from just my shovel, screen and pan. Two more days left in this outing, can't wait to get back in the river in the morning!

Attn Keene Engineering, Inc.: I love my Miracle Mat In my highbanker! The gold I find is mostly fine flower stuff! I have put a pan under it, another sluicebox under it, and a gold cube under it with nothing being found in them! It's all staying in my highbanker! 👍👍!

I love my A52S. It works great at Roaring Camp on the Mokelumne River every year. The Sluice legs & the no classifying is the best part.

Paid for my A52 the first time I used it. Found enough gold and a weekend of good times to buy a Keene 4 inch dredge . Just waiting until I can drive to Alaska. BTW. The dredge Paid for itself the first weekend also. Thank you Keene Engineering !

Currently waiting on my Super Mini. Can't wait!

Try the Inline-Classifyer with less/slower water.. 🤔

Except the long walk from Caesars down to the river carrying the heavy buckets of dirt

I would love a SUPER Mini with this sort of set up for small mountain streams.

😎☠💛🙌

Oh man you're teasing me here..I plan on doing similar. With my hopper, high banker, dredge combo. Ordered my A52S sluice in March. Payment was taken out, and put back into my account. Order details on Keene Engineering, Inc. says. Still pending.. I haven't spent the money in my account. It's sitting and I'm still waiting. Looking forward to getting out on the river's with my sluice. Getting some gold.

Dude put a mask on and move material

This is a quick video of the 4" ultra dredge with the latest upgrade "slow flow recovery system". Very simple and basic we remove the last 1/3rd of the all the riffles and lay in some expanded metal. We then place a 1/4" heavy gauge woven wire roughly 1" above and this does 4 things for fine gold recovery.
1. The 1/4" wove wire slows the water flow underneath less than have the speed allowing the flour gold to fall out of suspension.
2. The heavy gauge wire is round and rough so it creates in own riffle action. It caused the water to stall out the fines to fall through into a slower flow of water.
3. The elevated woven wire eliminates any effect that the larger material and rock on the riffle below.
4. Also for decades we have been trying to build a better sluice box the one thing we have been missing is not to do this in the beginning of the sluice due to all the chaos in the beginning of the sluice. If you give the flows a chance to become linear and zone out your recovery system become much more effective. I love this little 4" dredge Ulta. It is light compact dredge moves a lot of material for it size. I love it since it fits in the back of my Jeep.
