Plan and design your own home made suction dredge for …
The suction nozzle puts the high-pressure water in right at the nozzle. A power jet puts the high-pressure water in just before the sluice box.

I recommend ...

Gould Engineering Bazooka Dredge
I had constructed an infinity jet of my own design and I wanted to explore all the advantages and any problems. The design had an adjustable gap. Since this was a 4.0" dredge with a venturi jet generator, I based the jet opening to be the same square inch area of a 1.0" jet that was used on the straight jet. The area of the 1.0" jet was 0.785 sq.".

The suction nozzle drew 75 GPM and the tri-jet drew 90 GPM. I expected an efficiency of 100 GPM applied to the jet and sucking 200 GPM, with a ...

How do Suction Gold Dredges Work?
Power Jet or Suction Nozzle? The answer is that they each have advantages and disadvantages. The advantage of the power jet is that the operator of the dredge has to only deal with one hose when he is dredging. The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it.
