Perfect sized, dual purpose machineOur Proline 2.5” combo has become very well accepted with many prospectors who feel it’s the perfect size dual purpose machine. When this unit is being operated as a dredge, it’s capable of processing in excess of five cubic yards of material per hour. It’s also the smallest combo that can handle a continuous feed with a standard size shovel, making it the perfect size for one or two people. This combo falls halfway in size between the 2” and 3” models and has incorporated some features from both of them. For example, the stand and legs are longer but made out of the same size material as the 2 combo for weight savings. The polyethylene plastic hopper has been reinforced just like the 3” unit and the riffles have a stiffening rod on them to ensure a longer life and the sluice box is made of the same thickness of aluminum as the 3” combo making for a very strong unit.Powered by a Honda GX120 engine and our HP200 pump.
