| The Proline 2.5" combo has become very well accepted with many prospectors who feel that it is the perfect size of dual-purpose machine. When this unit is being operated as a dredge, it is capable of processing in excess of five cubic yards of material per hour. This is also the smallest Proline combo that can handle a continuous feed with a standard size shovel, which makes it the perfect highbanker 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 are made out of the same size material as the 2" for weight savings. The polyethylene plastic hopper has been reinforced just like the 3" and the riffles have a stiffening rod on them to ensure a longer life. The sluice box on the 2.5" is made out of the same thickness of aluminum as the 3" as well. This makes for a very strong unit.

Powered by a 4 horse power Honda engine and our HP 200 pump, this is by far the most powerful 2.5" combo available anywhere. The HP 200 pump was developed for high volume as well as high working pressure necessary for successful highbanking. This pump was also one of the first of its size which was engineered to be capable of driving an air compressor while still maintaining ample suction power.
All of the Proline dredge-highbanker combos are popular with prospectors who are looking for maximum versatility in a proven design. If the 2" combo isn't up to your needs, and if the 3" combo is just a little too large, then the Proline 2.5" combo would be the perfect choice |
