I just made 12V dredge out of 32 mm pipe Y conection with 45 degrees, water with jet goes straight, deviation does the sucction. But your system seems more elegant and better, because all material moves just in line... Great...
Well done your the first to use 500 or 1100 boat pump to achieve mini dredge. Your right on the money flexing 32mm end creat groves not just on the tip but cut back around pip would create a high clone affect, like half a mm to prevent pressure reduction as water levels around 32mm pipe to a point of higher pressure. Thus creating enough suction to better a hand held pump and batter is 18v makeita 5v lasts 3hrs or more. It will work as they say Iron forged
Don’t no the total psi you’re running from the pump but if u wher to increase the psi at head jet/nozzle it may increase the lifting power so u can run hose try 130psi 12v 8A self prime there about 40$ with the hoses glad u made the 2nd vid with black down give me few ideas good work keep it up
It will move the material but how do you collect it? It looks like it would just go through the pipe and not be collected any where do you have something to put on the end to collect the material?
Does it have enough suction to pull a jewelry ring and coins out of loose silt?? Someone with experience and details reach out to me please #SeattleRingHunter
I like your design. That is very clever the way you bent the one pipe out to create a ring of jets to create suction. Thanks for sharing!
That is the best 12v design I've seen on TH-cam. So, I will be giving that a go.
Bloody Brilliant!!

Good idea from you sir, it's an upgrade of bernoully ideas.
Thanks, like the Explanation, enjoyed watching the video.
Dude thank you , great design !

Love this design. Cheers and ty.
Hey brother have you made many changes in the last 5 years?
Thank you man for the video. 👍
brilliant design, ty. gonna go make one now. laters
charles dilmore good luck
hola buenas,saludos de Spain.La pregunta es si la has probado y los resultados???
great , im trying to make it now ! but which GPH power pump do i need?
Australian plumbing supplies don't sell the T you have displayed
Now how am I going to make it ?
using a suction dredge in Australia is illegal
With a 45 degree y and a 45 degree connector.
Thanks for the great information.
Would you build one and sell it to me? Cant find the needed parts here in german stores...
how much to make me one and ship it to canada?
Thank you for this explanation video. Much appreciated! Looking forward to your reply in 2019, sincerely "insolent," in Oregon usa.
great video
did you get any new info from it? hope it solved some issues or gave you pointers
dave
hi mate like your video, do you any greff from people for using powered gredges?
can't use it in mainstream areas in the UK.
luckily it's small enough to put in a backpack and be discreet...
Ninja gredgeing 😁
indeed
Thanks for share friend!!
Great idea!
I can make one, even in Australia
I can use one in Australia, especially on private property
it's good it's good it's good......
Does it have enough suction to pull a jewelry ring and coins out of loose silt?? Someone with experience and details reach out to me please #SeattleRingHunter
It pulls 2oz fishing leads so yes it will lift rings, coins and the loose itself as that's much lighter.
KiltedJock1 thanks for the quick reply and excellent explanation of your Venturi jet nozzle 👍
