Dredges almost always need to be mounted on a set of floats. A sluice box works because gold is 15 times heavier than sand and gravel and so is easily trapped by the riffles and carpet in the sluice box. Material is transported from underwater to the surface and run through a sluice box to capture the gold.

The 2.5 Inch Ultra Series has set a new standard for smaller size dredges. Models with a suction nozzle are recommended for shallow water. These dredges can be ordered in several versions and can also be converted into a high banker. A 150 GPM pump mounted on a Honda GX120 drives the 2½” dredges. Also, the state-of-the-art sluice box is more efficient, compact, and lighter. The jet flare and water level sluice box gives 30% more suction allowing dredge depths of nearly 30 feet.
