Anyone use one of these -- Osterberg's quick gold

[Bodfish Mike]

It's an Osterberg's quick gold . I picked this up at a garage sale and tried it out but can't get the mini dredge part to work. It's a small scale fluid bed that settles the heavy stuff to the bottom and then you dredge the light stuff off the top.

Work's real good as a drywash cons cleaner (how I'm using it now) gets the cons void of dirty water and keeps my panning station water clean -- however I would like to use it as it's designed.
Thanks in advance Mike

Here is something from this site. I am wary of anything using the term "quick gold" LOL. http://www.treasurenet.com/forums/gold-prospecting/42313-concerning-osterbergs-quick-gold.html

Originally came with just a siphon tube, the vinturi/dredge part is a user mod.

Old tech.... Basically a miniaturized elutration tower. Marketed with numerous design mods and under many names such as Goldwell (not the sluice), Quicksand concentrator, Gold Cyclone and others...if my memory serves me. You will have to ask my friend Google to see if there is more info
