- เผยแพร่เมื่อ 3 เม.ย. 2015
- Test run with djpitr's mini dredge. Worked some clay bedrock and found some nice pieces. Dredge works great as a bedrock cleaner upper and can be used to snipe with the smaller pvc attachments. Lightweight and can be hiked in to your gold spot. Low cost - $20 Harbor Freight bilge pump, $5 pvc nozzle, and the only real expense was the battery and hoses.

I will make little vid about it how i made the 12v mini dredge
Cool vid sluicelee :)
Looking forward to it.
Please do the video ,cheers
I love going electric
We need a bicycle powered version for Oregon & Cali...
How did you make that machine
Thank you! Built one tonight and will give it a try this weekend
Each inch you go bigger on the suction hose, the less rock you have to move.. My partner and I got permission to run our environmental dredge on the Sultan river one time at China Gap. We ran 80 ft. of 4 in. PVC pipe up the canyon side at a small
stream, damned it a little and installed a screen. We then ran that to a 4 in. ball valve at the shore line and from there in a flexhose to the eductor on the dredge. We had 40 pounds of pressure all the time and no noise or pollution. The fisheries agent loved it and so did we. We got the gold and no noise to let others know we were down there.
That’s awesome. I just figured out what that Ryobi 18v water pump can be used for! I’m gonna build this up. Great idea!
Now thats a nice and quiet build looks great for cleaning that bedrock great job thanks for shairing bro take care guys and keep up the great work.
Thanks jaffyger!
It is nice and quiet, always nice to hear nature when prospecting:-)
Thanks for watching bro!
Great soundtrack, man. Excellent idea to boot. Great post.
That's a cool little dredge.
Great job I gotta try this next!!
And all this time I've been told "Ohhh NO No... you can't make a proper dredge with PVC and bilge pumps!!! Don't got enough back pressure on the pump....won't work.....yessir....a complete waste of time and effort. You proved them all wrong Pitr. Hell of a build my friend. Can't wait to see your build video of it. I've got a 3700 GPH 12 volt bilge pump sitting in a box that is just screaming to be reincarnated as a "silent stealth dredge". Great job guys!!
Rich.
:) thanks , i ordered the 3700gph pump from ebay also :) i cant wait what that one will do .
nice setup , good idea
Cool!! That little dredge worked a lot better than (a mere humble me) thought it would! I see a new build coming up for use cracking and sniping underwater! Well Done!
Thanks Pete!
That little dredge surprised me too. Works well for shallow bedrock and sniping.
My bud Peter upgraded to a 3700 gph pump and it can get down a few feet and still move material.
All the best with the new build and thanks for watching!

What battery and how long will it last with the 3700 gph pump?
@@goopee76 Amigo , eu também tenho esta curiosidade , tenho duas bombas de 1100gph também 12 v como esta. Porém uso uso bateria de 12 v , e quanto maior a amperagem da bateria , mais tempo vai poder uzar qualquer bomba de 12 v. Uma bomba 12 v das mais fortes que encontrei , gasta cerca de 20 amperes/h, como gasta bem mais que as minhas , precisam continuar 12 v, e com amperagem o mais forte possível para durar mais, tempo correto da furacão da bateria vai depender do material a ser sugado , quando mais pesado o material , mais vai consumir a carga da bateria mais rápido . Espero ter te ajudado com o pouco conhecimento que tenho. Peço desculpas ao profissional dono deste canal por eu ter respondido você, pois ele certamente não teve tempo ainda para te responder . Mas provavelmente vai concordar com o que te passei . Eu não montei uma draguinha desta ainda , pois a bomba melhor para ela é a de 4700gph 12v ,consumo em torno de 20 amperes , não montei ainda pois esta bomba é cara para mim, e a bateria para durar mais , no mínimo teria que ser uma 12 v e acima de 100 amperes. Só estes dois itens já não posso comprar , sem contar que terei que comprar o restante que se somando , fica muito caro para mim. Att: Joel Rojes ,direto de Brasil .
cool idea for the mini dredge
Good job , best of luck on your gold hunts
zdarkluci, fakt dobrý!!! Fandím vám....
I love you man thank you for the video this is just what I m looking for to put in my boat for around swimming areas where you cant run gas pumps very short hose in to a small wire basket to catch stuff like rocks , pull tabs sinkers and YES YES YES YES GOLD RINGS and GOLD CHAINS thank you so much please do some more videos.
Awesome idea man well done thx for sharing buddy! 👍🤠⛏⛏⛏
Very nice and compact
Ya know, it would be nice to see just how you built it. Hose sizes, hose length and such would be greatly beneficial to the less knowledgeable.
That's a cool little build you have there Lee & Prospecting Partner...
Hmmm got my wheels turning now LOL!!! Great job my friend.. Keep up the great work..
+Flash In Your Pan Productions (Prospecting with Ed) Thanks Ed! You always make nice builds, can't wait to see your next:-) Happy prospecting, friend.
That’s a pretty slick setup you have there Great video
Thanks
Cool build bro
great vid! Thanks for sharing a little bit shine ;-)
Excellent !
Hello, very interesting. Gold seeker is also my hobby. Thank you have learned a lot what I can improve with me. Greetings Tom
Great Idea! Thanks Guys !!
Thanks Brick Au!
A fun little dredge to work some shallow bedrock:-)
Thanks for watching good sir
I live in Mississippi and I've done it for years here just to have fun with my kids. 1 speck out of bout 10k pounds of black sands lol. all you gonna find here is beer, southern hospitality, Trees, southern food and a shit load of black sand.
You definitely on to something bud. Patent that shit mate.. well done so simple its bloody genius.. 👏 👍
Now that's cool
LOL i had a dredge and i didn't know it! thanks man nice vid
Thanks MrErikm!
You never know, could be lots of things in the old garage that could help find some gold:-)
Thanks for watching!
Very cool...liked and subscribed
cool video
Nice
when I first saw this I thought "that looks easy" 40 hours of testing later I had it working with a 1 & 1/4 inch nozzel . volume it moves is very low but its perfect for working clay. Can fill a 2 gallon bucket with clay material in about 3 minutes.
Hey. I’m trying
To make this. What’s your secret? Had it sucking but jus barely. Running a 2000 gph pump.
@@krismaas3140 watch my video how I made it !!
Boa invenção . Parabéns ! Uma das vantagens dela para mim, seria por ser silenciosa e conseguir sugar um bom volume de material por ser pequena e elétrica. A desvantagem é que a bomba ideal ,e a bateria é muito cara aqui no Brasil . A bomba precisa de 12v e quanto mais amperagem ,melhor pois irá durar mais tempo. Se eu não tivesse comprado a motobomba 7hp a gasolina , e bem barulhenta , eu poderia comprar uma bateria de 12 v apartir de 120 amperes , e mesmo assim seria ideal eu ter 3 baterias para que enquanto usar uma por umas 3 ou 4 oras , as outras estariam se carregando para que não tenha que ficar sem trabalhar por falta de energia. Mas a draguinha é boa , adorei o silêncio dela , isto eu preciso muito , mas os preços dos itens aqui não estão a meu alcance. Fico bem caros devido as baterias e a bomba . Parabéns amigo. Vou tentando aqui com a motobomba ,e espero um dia poder montar uma desta que o mais difícil é a compras dos intes . Nota 10 pra você !
I really need to see the inside of this!!!!!!!!
Look it up on my channel I got details how I build it
AWESOME!!! I want to do this but have the hose go to the top of a five gallon bucket lid so its not limited to the radius of the sluice set up.
Migillicuty420a that will work only if you keep the bucket all under water ,and you could suck and fill the bucket . if you try rase up the hose out of water it don't work !!!!
kool gona make one myself thanks for idea
It's a great little dredge:-)
Thanks for watching!
Kreatif dan pintar Semangat terus saudara ku
best ever !!!!!
I have a 3500 gph I plan on making a good version of this. I bet this out does a shovel. Thanks
If I had been asked I would have said you'll need 2500 to 3000 gph to make it workn whether electric or gasoline. But there it is doing it's thing on 100gph! Well done.
1000gph
Great, well done to you , I'm in the uk and would love to do this, have you looked a different dry batteries, I was shocked to find when I replaced a battery on one of my kids ride on's the same size newer was way more powerful and no fluid.
That was a huge piece of Quartz you used as a weight.
Keep at it mate and the best of luck to you.
This would be illegal in UK ..
Nice build. Where did you find the music for the video?
cool accept the idea of that battery being near the water
Wow. NICE ~~~
sin-won lee Lets make one!!!
최고입니다. 잘보고 갑니다.
저도 열심히 하고 있습니다.
Show 👏
just made one see how it goes tomorrow
Sound kicks out at 1:43
SL...Love the video man!
You have some great suction there for a 1.5"
Are your hoses smooth on the inside like a normal dredge hose?
I cannot find those local to me so I'm thinking of using pool hose. They're not perfectly smooth inside and I might lose the flour gold to the inside ridges but I think I'd be able to do a good clean out at the end of the season and recover all of it.
Your thoughts??
You have to have smooth hoses , it would by very hard get the gold out of them
Hey Lee you can heat and mold PVC. Try heating and pinching with vise to produce a flat nose great for crevicing
GETTING OUTDOORS with PASTOR SAM Thanks for the tip!
I have a 750gpm so I'm gonna use your design and go to 1"
I'll get 1kgpm later I'll vid once I test it have you seen my channel and panning vids?
Nice rig! I like the DIY stuff. How far into the "Y" did you run your bilge hose? I think I'd like to make one and thanks for the video.
Steven Ham about 5feet
Would you mind if I used part of this video for a comparison video I am doing of hand powered suction dredge vs DC 12v?
Now all you need is a portable solar panel and you can sluice all day long
Nice job, it sucks is what matters and seems to be moving enough material. Have you tried a bigger bilge pump? i.e. 2000, 3200? very interesting
Put a screen on the inlet and it will automatically classify
Zap !~!!~ Owwwwww Got Shocked Dam Wet Hand lol
Nice idea. I have those materials but am reluctant to use my bilge as a dredge. Not sure if it's powerful enough to justify the pain in bringing it into the field. Best of luck and heavy pans to you guys though!
Erik
Eriktheprospector Thanks Eriktheprospector! I agree, this mini dredge isn't powerful enough to move much material, but does a good job cleaning bedrock, cracks, etc. We dug a nice hole that day with our shovels and ran the material through the highbanker, once we got onto bedrock, we got out the mini dredge to clean out all the crevices. The mini dredge found some nice pieces that day that the shovels never would of found:-) Thanks for watching, really enjoy your vids, and I hope you keep finding those Cali Nuggets!
Thanks Sluice Lee! Your mini dredge could be good on a float in the river to be used while sniping perhaps. Too much weight for me. I'm trying to bring less, but it's so hard to do!
Nuggets ahoy indeed !
Erik the Prospector get your self some 3s lipo batteries from hobby king. Make sure you don't let the volts go below 3.4 per cell or you will ruin them.
hello, I could use some help. I'm not getting any suction from this design. Most of the water pressure is going out the nozzle. any help would be awesome, thanks.
Buen sistema de draga para ir a prospectar en arroyos y torrenteras con poca agua.
yso un inciso, la boca de succión debería de ser metalica, les aconsejo usar una de acero inoxidable de 35mm que entrará bastante justa en la boca de la Y de PVC de 40mm. Es mas duradera y ademas es mas facil el remover el suelo con una boca de acero inoxidable qque con una de PVC
problem one. use smooth interior hose from pump to nozzle, the corrugated slows the water down. otherwise, brilliant. this is what i am making, with my own fluid bed type of sluice. 2. put battery in a waterproof container.
заебись! без шума и пыли
This there any thing in the y to help suck the water up and dirt and can we see that please
This is the best I've seen so far, Is there a jet ivolved?
Just look at my video i explain it there all :)
Thanks man for sharing and and I think it's AWESOME, I am going to try to build one also. Let you know how I made out.
Hola buen día la intenté realizar pero no me genera suficiente succión y estoy utilizando una bomba de 2000 gph que solución me daría preferiblemente la medida de la manguera gracias
whats the material your putting around the pump?
Hi, what kind of bilge pump do you use (brand and gph)?... Regards and congratulations for your mini dredge from Venezuela.
1200gph 12v 5amp
Hey I built the exact same dredge after I saw your video but the water just comes out the vacuum intake instead of going down the pipe to the sluice box. Maybe I need more pressure from the bilge pump?
Watch my video how to make it
Do you have the 2 pieces of wire in the suction edge of the dredge on a cross pattern so the big rocks don't go up the pipe? Thanks
doug johnsonj yes
La tienes en venta?
How long does the battery last?
Wie funktioniert das?Ist im Rohr noch was verbaut?
You still using the 1000 GPH Bilge Pump? The link you gave to purchase on eBay doesn't work. Can you give another link or model number to the smallest yet most effective pump you might think to use? Thanks brother! Subscribed!
whats the song called?
HI, I´M FROM BRASIL AND I´DO LIKE ASK YOU ABOUT WHAT KIND THE PUMP YOU ARE USING. I THINKING DO THE SAME FROM HERE. IF POSSIBLE, ANSWER MY QUESTION. THANKYOU!
When I think "backpack", I'm really thinking "big battery". Hope it's a short hike.
Seriously silly or trolling?
Lithium power baby ;)
How much does this dredge weigh?
What's this song?
Is it possible to run this on a kayak as you cruise?
Sure u can
nice idea but sluice should be 1/2 inch under water at the inlet and above water at the outlet to work correctly and not clog up. 1 inch drop for evrey foot of sluice is the norm
Hey guys, how prone is this to clogging? Thanks
NC Au Prospector we don't have problem with clogging ,i restrict the opening with wire so nothing big cant get in the hose
pity there is no explanation in the video of how they made the thing
That’s because this was my friend recording me in creek , I have video with details how I build it !
Are you playing??? Hahaha
what kind of engine do you use?
12v 1200gph electric bilge pump
not sure if thats legal here in my parts.
That looks wrong to me...? And let me say, I don't claim to have any experience at dredging! But you have the 'Y' junction at the working end of the pipe...? That means twice as much pipe for every increase in pipe length for starters, AND the clutter of having the joint/venturi at the working end? My humble advice would be...don't try to re-invent the wheel. Put the venturi ( 'Y' piece ) up at the sluice and use the extra pipe for more 'reach'. Best of luck to you though and I wish I was out there with you! I'm working on that... ;)
Can you send me a parts list incl. Hose size lenths
I don't have a parts list, but djpitr posted a video (th-cam.com/video/T9h69cvsXpw/w-d-xo.html) that should help with making a mini dredge. There should be some build plans on the internet, try searching "DIY mini dredge". Wish I could help more, all the best in your prospecting journey.
Thanks for watching!
I've been down the electric pump very small dredge nozzle route before, and ultimately set it aside as a waste of time due to the low volume. I found a simple hand dredge was more effective, lighter, and less bulky. the smallest effective dredge I found was a 1.5in powered by the HF 1in clear water pump. My post of the nozzle design is about the same as his end result also, but my photo's show the parts assemble fully expanded so you can see what they are and how they fit together. the lower the pressure of the pump, the wider the internal jet needs to be. hope this helps.
southernprospector.s2.bizhat.com/viewtopic.php?t=4885&mforum=southernprospector
The ideal electric dredge will become more realistic as battery tech gets better, which will allow the development of better electric pumps. to get better pressure, they need to be stacked in series.
hows this work, like a vinturi?
Go and watch my video i explain it there
What's max PSI of that pump?
This pumps have really no pressure, u can’t move water up from water level , this can get only bring the material right to to top of water , then u need to dump it to sluice
But the did you find gold ?? thinking of making one myself!!
+Keith Ress yea look at the end of the video
You can shovel faster than that
Nice little dredge but your sluice lost all your gold the entire riffle bed filled with material causing gold to wash right over the top and out the sluice, all you need now is a sluice that can handle that amount of material, either that you need more water volume over that sluice bed, nice dredge all the same :D
Halo saudara ku di mana saya harus mendapatkan alat penyedot seperti itu
Saya menginginkan nya
Saya dari Indonesia
Salam semoga tuhan selalu memberkati mu🤲
when i saw the battery near the water i thought you was russian lol
no sound
8 yrs old you ready to sell your dity? Or show more indepth build
sluice set up was not fine..
^5
Yeah it's very easy to make a little dredge like that nothing to it but you need a to set your sluice box up in a much better setup way too much water it's set up all wrong
