PROSPECTOR MODEL IN CREEK
The first thing you will notice about the sluice is no riffles! WHAT!! The Bazooka sluices do not use riffles. They use what is called a fluid bed or a boil box. A fluid bed works by keeping material suspended by injecting water into the box. The denser material settles to the bottom, and the lighter material washes out of the exit in the back of the box.
Here is a basic idea of how the Bazooks are built. You have a smooth tpered downstream upper deck. At the end of the tapered upper deck you have a bar grizzly that allows smaller material to enter the fluid bed or boil box. After the grizzly, you have the exit of the upper deck.
Underneath the upper deck is a chamber that runs the full length of the tapered upper deck. This chamber is open on the upstream side. At the end of this chamber is a wall with 3 pipes that go into the bopil box. These pipes supply the water that keeps the material in the boil box in suspension.
You need to setup the sluice with a good amount of drop and flow. You need this to drive the water flow in the boil box. You do not need to classify at all. You just feed bank run material to the sluice. The smaller material goes through the built in grizzly and enters the boil box. The water flow from the 3 pipes keep the material in suspension. The heavier material settles out and the lighter material washes out.
I could feed the PROSPECTOR model as fast as I could suck up material with my 3 inch super gold sucker.
Cleanup is very easy.s You just lif the sluice out of the creek, and place the end in a water filled bucket, and then shake the sluice back and forth. The material falls out fo the boil and into the bucket.
We did not run much material, but still got 5 tiny, tiny pieces of gold and black sand. If it will keep this tiny, tiny gold, it will keep larger gold easily.
THE MINI MODEL
The Mini model can be set up right in the upper deck of the Prospector model. You might ask, "Why would you do that?" With the Mini, you can sample a 5 gallon bucket in 8 minutes, take it out and do a quick cleanup to see if you are in the gold.kgphoto
