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.

Hear, hear!

"Please sir, I want some more!"

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.

Thanks to all suggestions, and the cross post Steve.

For a dedicated device, I'm leaning towards a Rino 750 because of the 2 way radio; the 755t looks loaded with unnecessary bells and whistles. Although the huge display on the Montana is a draw.. Like the Montana the Rinos are compatible with "Garmin Custom Maps" function.  I doubt the phone based apps have hardware that is as accurate under foliage, are as power efficient, or robust.

With a dedicated device, there is also something very cathartic about turning off the phone stuffing it in the pack and going walkabout. 

The OziExplorer app for Android seems a tad sketchy - searched the Google Play store for it on two different devices - each diverts to "Soviet Military Maps Free". Odd that the only way to get it is from a non-certified 3rd party web site - I'll take a pass. The Backcountry Navigator looks good though for the Android.

My "Old Faithful" Garmin GPSMap 60CSx appears to be reaching the end of its serviceable life, after years of being dropped on rocks,  bikes, down slopes, drenched, fallen into rivers, taped onto dogs, and being the point of contact on its bike mount between Terra Firma and myself head over heels on my mountain bike. Starting to malfunction a tad if you can believe it!  Can't say enough good about it  - some of the best money I ever spent bar none :)

I do a ton of work with Google Earth plotting targets, claims and such. My stompin' grounds are devoid of cellular data, so any device that is DetectorProspector approved and might have some capabilities for satellite imagery, overlays - I would really appreciate guidance.

Hang on, so your telling me that an efficient 4.2 litre turbo diesel, 6 cylinder landcruiser wagon isn't allowed in the U.S. but those massive GMC/Chevy/Dodge/Yukon things with 8 litre petrol engines that are gallon guzzlers and were pretty much dismissed from this whole thread because they are so thirsty...they are okely dokely neighborino???  

Am I right to be confused? 

I would consider larceny to get my hands on a turbo diesel Landcruiser like that in this country.  But you don't know the half of the story. In large swathes of this continent it's STILL perfectly legal to buy a kit to turn your efficient and clean burning diesel into a "rolling  coal" nightmare from hell - from a "respectable retailer" or "performance shop". If you're not familiar with the term, Google it. Just one of these abominations emits more pollutants than God knows how many thousand "dirty" VW TDIs ever will.

So yes, an 8100 gas engine isn't even blinked at.
