The gold in the pan in the above pic is the result from a couple of hours of doing that crevicing & cleaning out of the schist bedrock in the others pics from a river in Central Otago in the south island of NZ. Generally I just shovel straight in to it & hook the motor/pump up to the spray bars. This was the first time I used it with the ply board on the front to take my 2" suction nozzle hose set up. ![]() Like the little high banker above & below. I am a fan of making as much of my own gear as possible. Always a pleasure to share what little I know & have learnt from others & also by experiance. The other drawback of a 2 or a 2.5 is that these usually are not equipped with air.G'day Hoser John, Yer mate.Kiwi as in NZ (New Zealand) Great site here. So if a 2" will move 2 yards per day then a 3" will move 4 yards.Ī 4" dredge is a good balance between large capacity and compact size and can be moved and operated by one dude. ![]() Rule of thumb on size difference is: with every inch of nozzle size you increase, you double your production capacity. It took us a full week to dig a 10 yard hole with the 3". My first real dredge was a 3" and that damn thing nearly worked me to death because if the rock wont fit up the hose, you have to move it by hand. When people first get into this they tend to start small but ALWAYS move up to larger gear. Buy the biggest dredge you can afford that is small enough for you to handle and legal in your area. A lot of people ask me this question and my answer is the same. There wont be much difference and your first dredge should not be a new one unless you have plenty of disposable income. ![]()
