Sep 01, 2010I have done a little panning and sluicing and wondering if there is a better way. I am just a recreational guy who likes to camp and have something to do. Does anyone have any experience with the Keeene 2 backpack dredge? I like its portability (65lbs)and price (about $1300). I am not interested in anything bigger beacause I don't want to lug anything bigger around.

Oct 17, 2011I want to build a 2 suction nozzle gold dredge but I don't know how to do it. I make things by cutting and welding metal tubing and I believe the dredge is using a venturi affect to create the suction at the nozzle. I have listed some things that I think I need to know to build this and I would appreciate anything else you could add.
Jun 09, 2015Infinity jets were built by Gold Divers in Moundhouse east of Carson City and copied by many. I made at PESCO the flaired,pressure chamber fed tri-jet to easily rival the couple jet. Another tri jet,non chambered and not flaired was made by Dahlke for many years prior to Bobs passing RIP as a GREAT person,engineer,manufacturer and father.
Homemade Gold Dredge. Author Chris Ralph. No question that many folks interested in prospecting for gold would love to own a dredge. No question that dredges are very cool pieces of prospecting equipment, but the prices for new ones are really high. through a jet. The fast-moving water creates the suction in the jet. This way
The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it. The disadvantage of the power jet is that the power jet and supply hose must be kept under water at all times. Therefore they do not work very well when working in shallow water.
Dredging is the operation of removing material from one part of the water environment and relocating it to another. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material that has some value or use, or

The Proline was the first 2 dredge with this feature. Due to recent changes in the pump and jetting system on this dredge, the suction power has dramatically increased. This increase in power led to a new classifier with a riffle system that produces a more effective low pressure vortex behind the riffles themselves, improving fine gold recovery.
This is a gold dredge that's used in wet environments such as a creek, stream, or river. It can even be used in deep water with air. This was used mostly for display. The venturi jets pull it self forward into the material. Just keep it from tilting more then 20 degrees to either side so the gold goes into the trap.

May 08, 2007No question that many folks interested in prospecting for gold would love to own a dredge. No question that dredges are very cool pieces of prospecting equipment, but the prices for new ones are really high. the suction in the hose is actually created through a Venturi effect by pumping high pressure water through a jet. The fast-moving
A modern dredge works materials, by means of a suction system, which draws gold-bearing materials up through the suction hose by a vacuum effect, from the use of a power-jet intake, which powers the dredge. This allows gold-bearing streambed materials, to be vacuumed up from underwater and processed through a sluice.
The suction dredge required only a centrifugal pump and gas motor, a float pontoon system, a sluice box, a venturi jet generator, a dredge hose, and a nozzle. This discussion involves the venturi jet generator that provides the suction for the dredge to operate.

Nov 04, 2012The big difference I see is whether or not to use a gold dredge style venturi nozzle that allows all of the hard organic items, twigs, sticks and leaves, to pass through the nozzle and be separated above water or to use a muck through pump approach and filter out the harder objects by using a filter strainer on the intake.
