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!

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.

I just ran across this video and Wow how cool is this. Check this out you will enjoy it. ... See MoreSee Less

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.

I like my four inch with the impact box , when run right it gets everything !

😎☠💛👊

Gutted mine.upgraded it to dreammat dredge mat.added 9" of sluice.its way better now.went from 15 pans of cons to just 1.faster cleanout.and insulation.= more dredge time.gold recovery is even better

To much turbulence for dream mat

"Pumpinstine " the neighbor nick name.
These pictures are from a customer that wanted to rebuild his beaches. He estimates that he averaged around 15 yards per hour. He used a 4" suction system with a 5" discharge and a 23 hp with a P350S pump.

Would love to see you guys make an 8” Supermax as a standard line
