A suction dredge is basically an underwater vacuum cleaner that sucks (hopefully) gold-bearing gravel up and runs it through a sluicebox. In more technical terms, suction is created by a motor-driven centrifugal pump moving high pressure water into a jet system, creating a low pressure area that creates suction at the nozzle via the venturi effect.

Using a dredge, an (experienced) operator is able to process a much larger volume of streambed material than with any other small-scale hand-mining apparatus.
