Its called an auxiliary flow or infinity jet. But good job with the pvc version. Needs a hose to be able to tell how powerful it is with that pump... I'd use it as a nugget trap with a trigger for sniping.

That, my friend, is an impressive bit of kit. Great explanation how it all works too. Thanks for sharing. Atb Dave

I watched you're other video on how you made this also. Awesome job and video thanks for the knowledge 🤔🖒

If you install a venturi passed the inlet, you will increase the suction.

Absolutely brilliant, you explained it well. Suits me

awesome bro ..will try and copy if that's ok just have to try and work out your jet system in the middle, good idea but will have to muck around a bit. Thanks again..

I made one easier all I did was took a 2 x 2 x 1 1/2 y pipe piece like you have and used a 2 x 1 1/2 down size end cap and rimed out the center to fit a 12 inch long 1 1/2 pipe inside it and glued it and left it stick out of the end about 3 inch and ran the pump hose on top and used a 6 inch long 2 inch pipe and 2 x 1 1/2 cap on the other end and a 4 inch long 1 1/2 piece on the other end it works like yours thank you for the input on your Idea it help me out on making my 12 volt dredge

I guess I should break this down into its separate parts and explain the parts I used and how they work... I'll make another video soon

I think I have figured it out. There are 2 pipes going into the centre plumbing 2 into 1 part. The one on the left is 40mm and only goes into the as far as it will go before hitting the stopper. The right one is 32mm.The 32mm pipe extends right through the 2 into 1 part and into the start of the 40mm pipe but only just. It looks to be a snug fit so he has cut notchs in the end to create the jets. The bilge pump pumps water into the 2 into 1 part and the only place it can go is through the notches into the 40mm pipe creating a venturi which is why when it is running the pump doesnt blow water out of the pickup pipe. Very clever design and I will be having a go at this. Have you put a hose on the end of the 40mm pipe to transport the gravel to a bucket or sluice and did you lose and power doing this? I have a 3500 gph pump just waiting to be used. Thank you KiltedJock1.

Kardeşim teşekkür ederim verdiğin bilgi için 🎉 👍

I'm must be daft, any chance of a tutorial? You explained it well, I just can't wrap my head around the inner tube/holes/depth. Thanks regardless, got me pointed in the right direction!

This is so great, thanks mate!

Looks like that thing could drop a walker dave.

Hi.... Can you sent me step by step detail on how to make this dredge... interesting dredge.

Very cool. From my research, what you built is a electric infinity jet (google it). I'd like to see the details of how you built it.

Hi, would this work with a 1500 gpm 12v pump ?

We call it the goldsnare

Very cool. Could you please descrieb how the middle section of the dredge is called and where you have bought it (perhaps with article number)?

Awesome!

can you give a part break down

ive made exactly same and not work if you use longer drain pipe and when the pipe is not full covered with water

how much to make me one and ship it to me???

what make of equal t did you use???

Good for you, have you tried in in real creek with gravel? Get any gold?

Can you do a how to make it video

your suction problem is if you install Hose its not gonna work lol ! that's why you are not trying that !

where did you buy the 40mm to 32mm tee or did you use a convertor

Please can I pay you to make and send one too Cornwall I have the pumps

4:50 suck starts here

if I get my son to help me make video ill show you how to make one

How long can it run on one charge?

I built the exact same pump going from ur video and it doesn't work

Nice

Can anyone translate this into English? Thanks

sent u a email
