A revolution in suction nozzle design, finally, DRY LAND dredging is a reality! The Hydro-Force Nozzle is built specifically for use where water is in short supply. This nozzle can be used in low water or completely out of the water and it has suction force second to none. It will literally suck gold off of a dry sidewalk! The Hydro-Force can also be used underwater, just like a conventional suction nozzle, with the added advantage of a built in water jet for flushing gold off of the bedrock.
