Suction dredges are commonly available “off-the-shelf” in sizes ranging from a small backpack size intake of 2 inches up to a very large commercial dredge intake of 10 inches.

Gold Suction Dredges come in a wide variety of designs and sizes of intake. This is often called 'long arm dredging'. In cases where the water is shallow the gold diver may simply use a snorkel. In addition to pumping water, the engine can also produce compressed air for the dredge diver to use while underwater. The sluice box then expels the worthless gravel and retains the gold. The header box dampens the rush of water and gravel so that it flows evenly into the sluice. Suction dredges utilize a high pressure gasoline powered water pump to suck up water, gravel and gold and inject this material into a sluice through a header box.
