Boulder dash - Have you ever run any wet vs. dry comparisons on your dry washer? I did and was quite amazed at the results. I took buckets of DW tailings to a stream some miles away and ran them in a sluice. Steve was there and saw it too. I'll have an article on it in the next issue of the ICMJ. The bottom line is that the dry washer did amazingly well - far better than I expected. (I use a Keene DW2, 212 12V puffer)

Yes I have Chris, my 151 drywasher recovered 92% of recoverable gold with one pass. No unnecessary pre screening.  Just used the screen it came with.  Strangely it lost very little fine gold and lost the larger fluffier types of gold.

Of course it depends on the nature of the gold in the deposit you are working. If it were all fine minus 30 mesh type stuff, you'd get less recovery. In my test I actually got slightly better than your 92%. I did no pre-screening other than tossing aside large rocks, just the screen on the dry washer itself.

      Hi Guys,
      My mate has an EZ Pickens backpack style dry blower vac. Hasn't been used in a long while. Its a wild looking piece of equipment, looks like a jet pack! I have been unable to find any information, manuals, value etc for it and wanted to put the feelers out overseas to see what i can find. Google only shows up some old private sales and its mentioned in a few threads...nothing in google 'images' either. I would like to clean it up, value it and see where to from there.
      Any assistance much appreciated:)

      I got into prospecting kinda hot and heavy. I like to build all my own equipment mainly cause I can at a much lower cost and have a better product than whats being sold commercially. I know this forum is mainly geared towards the prospector swinging a metal detector, if Steve does not mind I would like to post the how to build the Viper-Vac here in these forums. I also built this trommel and many other tools I use.

      Hey everyone, just wanted to start a new topic on Drywashing for gold in Australia.
      Here's a video of me and my mate Pete out on a quick overnighter' it's still dry enough here at the moment but finding time to get out before it starts raining might stop us from more footage this season.
      Steve' feel free to move it to a more relevant section if needed, also if others want to add info video's etc to the same topic feel free just keep the topic on Australia.

      Going to finally get a gold trip in last week of Oct, hopefully, i heard that area got some good rains recently,just wondering what you guys that have been near winnemucca think about bringing my drywasher ,is the ground still too damp. I heard they had 2 storms that dumped 1/2 of rain each one.

      Looking to maybe buy a dry washer. What does everyone like? Power blower, electric bellows, size, brand ext.. Is one brand better than another for fine gold recovery or do they all preform the same or close to the same.
      I would be grateful for all information.

      Thanks Greg,
