Which Type of Gold Dredge Jet is Most Efficient? 

I have never gold mined before, but I happened to stumble across gold dredging just about 2 weeks ago. I immediately thought of a different use for the technology as a local service i can provide to people. I’m a big data guy, and it was pretty hard to find information to learn more about jetlogs, the jetting, nozzles, all of it. I truly love what you are doing for this niche community. I did a looooot of video sifting, and was eagerly awaiting your video to learn some more, since you provided the best information by far. Data backed and simple. This week i completed my first successful 4” jetlog, and in my test runs, so far i have been able to attach a 60 foot 4” suction hose with insanely strong suction, and pumping about 5ft head after the jetlog. Which serves the purposes of what i need. Its been a cool learning experience, and im excited to dial everything in, and hopefully try and step up to a 6” dredge and even longer hose setup next 👀 i appreciate You, man 🤙

I would really like a ready-to-go kit that I could attach to my 2-inch power head sluice with a Dream Mat in it.

Love your work and videos...keep going on the 2" inch dredge battery pack efficiency model i would definitely be keen to get one...hooked up to your your double decker high banker...what a machine

I can personally say that venturis in series greatly increases suction power. We used a 4in hydro force nozzle to lift material at a high velocity 6 feet vertical, then 20ft feet horizontally to a second venturi, then 10 more ft to the dredge. None of this was done underwater, so no buoyancy effect to help lift material. Spacing of the venturis did seem to matter so it would be interesting to see you experiment with that. Another thing that seems to help increase suction is to add air to the nozzle. They seem to suck harder when air is introduced into the nozzle. I have seen air lift systems to clear out a well and it's amazing the effect you can get from air trying to rise in a pipe. Best of luck to you.

You are really progressing with all of your research on smaller versions of dredges. Love it! Floating mini Le'Traps.🥰 comes to mind. Although I probably will never use one here in Alberta, at minimum, a powerful portable jacuzzi to ease my aching joints at my age. I did link your video to some US prospecting forums and my Facebook drop riffle forum. Keep up the great work Kyle! 👍

Hello from California. I’ve been using gas and electric dredges for year’s. Right now I’m using electric 3700 in your video with a Goldibox dredge and high banker. I believe you Larry that makes the Goldibox dredge have a lot in common. The two of you might be better off working together. I will be watching you both. Good luck

Definitely would be interested in setting one of your dredge nozzle and upgraded bilge pump. Would like to try to assemble a small 6” wide floating Dredge that runs off batteries

Hi, thank you very much for everything you made us understand 👍 Personally I would be interested to see a 2" dredge with the sluice on the surface, on floats and that it can also be put on its feet for places where there is not enough water for the dredge to float. Why not fix the battery on the dredge, and the pump is attached to the dredge but quickly detachable so that you are free to position it in the watercourse. Greetings 👋

Cool Video, I'm excited to see where this project goes.

My head started to hurt unbearably at the 5 minute mark - GOD BLESS THE FAST FORWARD BUTTON.

I have been following this like the superbowl

The one thing that I noticed that you didn't try was, with the double suction nozzle, was to have one of the two further along down the tube. Just a thought.

I use SeaFlow pumps for my electric system as well.....so I am extremely interested in the improved impellers for the 4700 gph pump and the nozzle with a jet attached. I am also in the process of making an electric dredge and am learning a lot about what I need to do from you. I am not 3d printing though, so my craftsmanship comes down to what is at the local hardware store.

Hmm...... maybe you aren't into engineering, Kyle? But why don't you read yourself up on what Bernoulli wrote 286 (!) years ago about hydrostatic pressure and use his formulas instead of the try and error approach you are performing? The solutions are there - just use his formulas, but here is the gist of it: Bernoulli's theorem: How the pressure and velocities in a fluid (water, air, etc) are connected The pressure in the liquid + the velocity pressure + hydrostatic pressure = constant as long as the energy level does not change. General principle: The Bernoulli effect is in principle a way of expressing the conservation of energy. The work exerted on a volume of liquid (water, air, etc.) due to pressure is equal to the change in kinetic energy of the volume of liquid. General characteristics. Where the flow is slow, we will find a relatively high pressure. Where the current is faster, there will be a lower pressure. The curvature of the streamlines reflects pressure gradients (pressure forces). Decreasing pressure in the direction of the center of curvature. In short: P+21​ρv2+ρgh=constant

I've looked at the goldibox and it seems to be a good idea for remote locations but it seems like it needs some Kyle like engineering to get it to the next level. I'm patiently waiting for the box testing to begin.

You now got data for future builds with a suction nozzle . I played with a suction dredge a little . Spent most of my time clearing a clogged line . Might be a good Idea to figure a nozzle design that prevents line clogging with elongated rocks . And hose to fitting adaptor the avoids fitting sitting in side line down stream of flow . a gravel full suction line is very heavy

Very interesting. Have you gotten any Aus au yet?

Great info, but since it seems you are likely gonna be in shallow water I would more look into a suction nozzle instead of a power jet.

i thought that you could NOT dredge on the sask river, or any where in alberta. so where do you plane on suing this.

Curious to know if a twist in the double jet causing a spiral flow projection into the tube would have an increase in suction and flow

The 2 vids are up on my page I messaged you. Hey wondering how why the divider in the backside of your highbanker

Hi ! 😊

better u show like a experiments
