These guys do some really good gold dredging videos. They have a Youtube channel all about it but this is their latest video that they've made after we came out of lockdown in NZ. The water would be pretty damn cold as lockdown took us towards winter!
They find some pretty good gold! You'll see them smashing out the rock with rock hammers to free up nuggets hidden in the rock. A fair bit to learn from their videos.

Hi all, hope everyone is ready for dredging . I have a 2" Keene dredge, with the hard floats. Dose anyone how much air to put in the floats? Don't want to blow them up, but need them to float good. Any help would be good, I tried to look on line but could not find how much pressure to put in them. Thanks Dean

I have been making Gold dredge nozzles in our business for quite a few years now and we sell them on our website and Ebay. We make them in 2", 2-1/2", and 3" OD Tube with slip on connections. Plus we give the customer the choice of a classifier or not, welded to the nozzle tip instead of charging extra for a "bolt on" accessory when they should be included.
We always have made them with 1-1/2" OD tubing either slip on hose or threaded hose to the water pressure line with a reducer to increase the pressure to the nozzle.
Are there any people who use 3.5" or 4" or even 5" nozzles? If so, what sized water pressure tube do you run for those? I am thinking about making a bigger product line for our customers and am all ears in your input.
What would be your best nozzle? Short and stubby? with or without side handles? Different nozzle sizes? Water inlet tubes?
I am also thinking about making them out of 316L stainless for the salt water people's.
Any ideas would be greatly appreciated.

We make them with OUR made parts, no someone else's.
I purchased a newer Keene 6” mini dredge last year with GX270 motors and PHP 500 pumps. I used it quite a bit last summer but it was all in the old mine cuts that we dredge in. Not once in a river. The suction is unbelievable.
My question does anyone have experience with the bigger motors needing more floats because of the weight? The motors themselves are 20 lbs more a piece and not to mention all of the weight from the water volume and hoses being bigger. Keene makes the outriggers with floats for them. I was going to make something similar uses two 30 gallon poly drums.
