3 inch Sampling dredge:
1-3 cubic-yd/hr
Still lighter and smaller than a 4 inch and can move a lot more material than the 2 inch.
Still low on production for a serious operation. Portability is pretty good for remote places. |

4 inch Sampling/small scale production dredge
1-4 cubic-yd/hr
The smallest of the production dredges but still good at sampling for pay streaks.
A bit harder to lug around, it is heavier and more work to put together and take apart. Fairly mobile still, this makes it good for more remote sites. | |

5 inch – larger scale sampling/production dredge
2-10 cubic-yd/hr
Good for larger operations and can move more dirt than all the other smaller dredges. Still good for sampling but on a larger scale. Hose is flexible and can be operated by a single dredger.
Heavier to disassemble and move around. May have multiple or larger engines. | |

6 inch – a good dredge for the serious prospector/smaller commercial production dredge
6-15 cubic-yd/hr
A useful size for someone who has found a sizable pay streak and wants to get all the gold out that you can.
You can move rocks gravel and sand up to about 5 inches across without a plug up of the hose or jet.
Larger nozzle makes it harder to sample with, although you still can sample larger rivers to locate gold in bigger areas.
This hose isn't as flexible as a smaller dredge although one person can handle it well enough for production. Two man teams are better because the rocks are uncovered so quickly by a 6" unit that a single dredger can be overwhelmed with the work of clearing of large cobbles and small boulders that don't fit in the suction nozzle.
Can have multiple engines or engines in the 15-20 Hp range. This is a heavier beast to haul. Be ready for 2 or more assistants. | |
