    Hand Dredge?

    So what is the consensus on the Hand Suction dredges? Do they work? Are they a waste of money? Since Cal. has banned motorized dredging, and what they do seems to follow suit up here in Liberal Land(Oregon) i have been thinking about buying one. So if they work, which one or which size, do you all recommend?

    Re: Hand Dredge?

    After using my hand dredge for a short while this weekend for the first time,
    I couldn't get my gold vac out of the truck fast enough to start using it instead.
    Guess if you have never used a vac then the hand dredge is better than nothing.

    The hand dredge I built incorporated two check valves so I could pull in material on the upstroke and then expel material on the down stroke through a hose into a bucket or even directly into a sluice with the crash box adapter. That gets tiring fast

    With the vac, the motor does all the work and all you have to do is run the nozzle over the crevices or around boulders etc. Works either wet or dry

    The hand dredges are inexpensive but the vac is worth every dollar due to the amount of material you can gather faster, coupled with the ease of use, along with having more suction power.

    The motorized vac should be legal due to the fact that there is no discharge back into the water source.
    Problem with the vac and working in water is that the bucket fills with water quickly and has to be poured off often. (mine has 10 gallon capacity)

    Cool. So how well does it work? What size tubing did you use? Do you make them to sell?

    Way to much work for this old man.

    Go Gravity!


    It can be done with as little as 50ft of 3" hose.

    Homefires.... awesome information Thanks!!


    Rebel & Goodguy Thanks for showing me your setups I never seen them before. I am sure they would be just the ticket for cracks and crevices once the overburden was moved. COOL! NVRADAR

    Re: G.G.?

    Do you have a suggestion for what i can use for a seal in a 2" bodied one? I made one today but what i thought was going to work for a seal don't. I was thinking maybe a couple flat washers just smaller than the inside diameter with a piece of leather sandwiched in between? What would you suggest?

    Might try this thread and get some ideas: http://forum.treasurenet.com/index.p...,336048.0.html

    Here is what I used on my 2" ....Ran a length of threaded rod through the handle to a 2" test plug from Home Depot.
    You adjust the seal by tightening or loosening the nut.

    Thanks for the quick reply and the link. I looked for one of those test plugs a Lowes today but didn't see them. Will have to look again. Thanks.

    Re: Hand Dredge?

    OK. I went back to Lowes and found a 2" Plumbers test plug and also picked up a 3/4" bushing to fit my pull rod, and a washer that fit inside it and let me run a 3" long 5/16" stainless bolt through it and the plumbers plug and put the wing nut on so i could expand it. Guess what? It works. Thanks guys.

    I forgot to mention that you have to modify the large red plastic side of the test plug to match the smaller side so the whole thing fits inside the tube.
