Concentric coils are hands down better for pinpointing and they will punch deeper in the center of the coil. They just don't tolerate being under electrical lines very well. Thankfully most places aren't under the power lines
This is perfect! I'm headed out to the North Saskatchewan and I'm using a 20 mesh bucket sluice with a paint mixer and a drill. I didn't know this design of sluice existed but it's perfect for our flour gold here.
Good to see you out having fun John. I’m still spoiled by being down South, getting warmer but I am waiting for a bit higher temperatures before I get out….LOL
A nice, easy controllable flow works well for flour gold. Tsunamis might capture chunky gold, but with flour gold, a lot will get blown out of the highbanker.
@@TheJohnEdmonton - I always imagine a sluice being a miller table, and work up from there. Bascially, a sheet of glass for water flow, with minimal turbulence in the matting or drop riffles, and as close to zero bubbles on the surface as possible.
That square mesh screen works well. It doesn't plug up much and is easy to clean with a brush like you wrote. Big congrats on getting out in January in Alberta John!
Thanks Kyle......It was nice to get out. I most certainly needed some exercise. All the best to you in Australia. Looking forward to seeing some new RU-vid posts soon.
An (((Old))) wool blanket works best . Hard backed to something for ease of cleaning . used on a steep angle 24 degrees as James gibbons did in the 1800s . it is 95+% efficient the blanket utmost used in his comparison video was part of the same blanket used here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mcl49rxf2qY.html
I like how you just draped that blanket straight into your drop riffle sluice. Seems to work great on that Alberta flour gold! Did you find much leftover gold when you dried out the blanket later?
That's awesome John! What you call flour gold looks like cornmeal to me. Wouldn't it be nice to figure out a way to sorta preheat the water before it hits the Geo? I don't see how you kept it from freezing up.
I mined further down stream a decade ago average about 150 colors to the pan got wheels on the sluice since. Using a little hard water eh? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mcl49rxf2qY.html
When "drop riffle" river sluices are set up properly, the gold just drops into the first few drop riffles and hang on to it. Just like gold drops into crevices in a river.
John I have mined with a wool blanket in my sluice since the 70s . I use hard backed old wool blanket, new wool is very expensive and does not work well. Got mine at good will for 20bucks . It is hard backed on a piece of plywood I have caught up to 3 grams on a 9"longX12"wide surface on a 24 degree angle . that angle worked for James Gibbons the inventor of the grizzly . it worked for me ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mcl49rxf2qY.html
The wool blanket is making a comeback! I still can't wrap my head around just how well it seemed to work in my side by side sluice test. I should experiment with it some more out in the field... Good video!
A wool - 2 x tiered flared highbanker. What could go wrong? I love it. I hope your posts continue in the "Land of under." You have made a good mark with the prospecting community.👍
Nice video John. I didn't know that you have a RU-vid channel. I followed a link you posted on detector prospector this morning. Of course I'm a new sub.
I have been metal detecting and prospecting for over 30 years. It used to be that I got more gold metal detecting, but now it's more gold prospecting then metal detecting.
Great video John! Thanks for sharing. Good results for sand! I would almost call it “muck/overburden” Saying that. Looks like a nice spot, if gold drops there now it probably did 100 years ago. And has been sinking below the sand every year into the gravels below. I would myself try digging 2-3 feet deep there sometime or get underneath the sand. Digging deeper is like digging back in time, there could be an old layer of gravel buried just a foot or two below all the last 20years of sediment. Good results up top sometimes lead to awesome results deeper🤙🏽
There is more gold down deeper. This area has been prospected for about 150 years. I bet every rock down a couple of feet has gone through at least one sluice. Fortunately, the gravels get replenished a bit every year after the spring flood/melt. I was curious as to whether or no there was gold in that muck or sand and how much. I guess I got an answer.
SUCKS! I was SO HAPPY when Garrett came out with the waterproof pinpointer.. until I bought it. That's right.. IT DIDN'T WORK! I am so pissed off, as this is NOW.. the SECOND Pinpointer I bought that DOESN'T work.. RIGHT out of the Box!
Careful posting your tailings running straight into the river , big fine for that , especially cause you have video evidence , they can use that now a days
Be careful with your tailings running into the water , bucket kinda acts as a settling pond but I can see them being stingy and giving a fine for that no tailings pond
Got one too and works well with my 6 inches home made high banker…can’t wait to go for gold again this season as for today still busy..,,hopefully we will meet at the NSR one if this days….good luck to all prospector.,,,
