I like the idea and 3d printed implementation. Would like to see a profile for the XP shaft.

Don't steering wheels magically switch sides when the vehicle crosses the equator?

Well, that's fun and all, but I think this would be more practical: 

BAE Titan XD

I'm going to make a wild guess and hope it's something prospecting-related based on the videos' local. But that may just be wishful thinking on my part. :)

A topic close to my heart. What I do is collect representative gold specimens from the area (via sluicing or panning - your methods may vary), then placing them in vials or baggies and salting in amongst the target area. Test various Deus programs and tweak the settings to find what works for you. I like the 9.5" elliptical for poking around boulders and cobble.

Oh wow. How many gasping breaths of rarefied air would the bearer have saved with a half a kilo lighter Deus instead? 

For this ultra-specialized, expensive, once in a lifetime, low temperature application, whatever detector you choose - ditch the stock batteries and custom fit them with lithium thionyl chloride primary cells, and have plenty of power till -55C.

Would like to see those pics of your slotted variant 2Valen!

Good eye :) That classifier gave its life for the cause lol.

You want to cut up buckets that are slightly smaller than your typical 5 gallon so they will sit deeper in a 5 gal full of water. I often stack 3 sizes at a time and "jig" them with a shovel or two of bank run in the top. Another tip is you might want to put a small "collar" under the bottom lip of each screen pail so they don't nest tightly into each other.  

I like the nested pan idea for it's compactness; good for quick testing. As for other solutions  when I'm somewhere in between test-panning and highbanking, I made a set of bucket classifiers. Mesh sizes of #1.4, #4, #10, #20. The bottom one in this pic #40 and proves to be impractical out in the field, even though  I opened it up drastically around the sides as well:

Genius. The 12" Jobe et al classifiers work great in 5 gallon pails, but leave a nasty scar in any pan large enough to accommodate them. This arrangement will compact nicely for transport as well. You could even nest more of these these, doubling the mesh size until you're in the zone. 

Great to hear it Jim. In case I miss it, will you shoot me a link to your plans when they are dialled in? I hope you still have my email.

Hey Jim, great work! 

Looking forward to the assays of what you've found. 

And of course those Wilfley table plans while you are waiting for cooler weather 😉

Surprised the "Uncommon Wisdom" piece didn't even suggest weighing your coins, although it included the word "weight" exactly once, with no context. Knowing the dimensions and the weight of a pure gold coin you are home free. Common sense seems somewhat uncommon among bloggers.

Anyone remember Archimedes and the king's crown? This scam has been around for time immemorial.

Chris' book Fists Full of Gold is also loaded with info on running an economical operation. 

Highly recommended.

I might have to take you up on a set of those plans when they're available, Jim. Tradition and all :)

On a tangentially related note, I've often wondered if the magic that is the Wilfley 'saction could be emulated using a programmable logic controller, drivers, and a linear actuator. 

Best, 

And here we are under a heavy snowfall advisory. 

Sigh.

James Kwantes is a reputable source IMO, however YMMV.  What he reports above is an extract of an annual trip sponsored by the Yukon Mining Alliance for select analysts.  In my personal opinion only, I find the VIT stock dilution of ~900M shares too much to swallow.

Here is another angle on the same Yukon tour exposing other plays, but without specific details of VIT.V  https://ceo.ca/@goldfinger/what-i-learned-in-the-yukon

A de-tuned garage door opener would have no trouble finding a lump that size lol. 

XP Deus|ORX  HF Elliptical DD 9.5" x 5", no cover, battery in shaft : 280 grams

This is my prospecting dog Dasha, yesterday. After detecting a good spot she often helps by dropping big yellow nuggets in my pan. Now if I could only adjust her discrimination for sticks and tennis balls....

Here's a picture from August of my son and a Thingiverse sluice I printed of PLA. It's not going to stand up to a lot of abuse in the real world that's for sure. I've used the Keene flares; this is much more of a toy, and I doubt it will see use twice. 

To which rexhavoc cheekily responded: Badgers? We don't need no steekin' badgers...

Classics noted above. But one that often overlooked nugget is Charlton Heston in "Mother Lode"  :)

"You stay the hell out of my mind, laddie."

Which parts are 3D printed - the crossbar mounts and/or the mat, and what mateial?

I notice there are a few sluice designs on Thingiverse. 

Around here those are referred to as nuggets lol.  Quite the antediluvian flood needed to move those chunks  :)

Anything +30 mesh around here is a nugget.
