A gold mining dredge has a totally different design and purpose. A gold mining dredge utilizes a device called an "eductor" in conjunction with an inexpensive water pump.

Before the Proline 2.5" gold dredge was created, the 3" suction dredge was the smallest machine available that could be equipped with an air compressor for diving. Most 3" dredges are very close in size to the 4" dredges, and most all are powered by the same engine/pump combination.

It sits on its own frame with pontoons that were matched to its size and weight.
