The suction hose should be both flexible and light weight, but it must also be capable of withstanding the powerful negative pressures encountered when operating the gravity dredge. The same type of suction hose that is used for most gasoline powered dredges should also be sufficient for use with the gravity powered dredge.
The size of a gold dredge (1.5 inch, 2 inch, etc.) is determined by the diameter of the suction hose— the larger diameter the hose, the more material can be processed. A floating gold dredge is essentially a floating sluicebox that uses an engine and pump to create a vacuum and send gravel (hopefully gold-bearing gravel!) into the sluice box ...
