Proline 3" Highbanker Suction Dredge Combo

The Proline 3" dredge/highbanker combo - of all the dual-purpose machines available today, our 3" highbanker (power sluice) is by far the most capable of putting in a full day's work. Even though it isn't much larger than the 2.5" combo, it can easily process twice as much material when being operated as a dredge and can handle continuous feeding by three men shoveling as a highbanker. Our 3" combo is equipped with a large aluminum reinforced polyethylene plastic hopper for large capacity of bank run material. The two triple row spray bars ensure that all of the gravel, clays, roots, etc. are thoroughly washed and separated before running through the recovery system.

The grizzly is designed to be strong, yet surprisingly lightweight. Like all of our other grizzlies, this piece is made to be removable. This is done for two reasons. First, this allows easy access to the classifier and black "V" ribbed matting for inspection and/or clean up. Second, if the combo is going to be operated solely as a dredge, the grizzly can be left behind for weight savings.

Proline Highbanker / 3" Gold Dredge Combo
Proline Highbanker / 3" Gold Dredge Combo

This unit is powered by a Honda GX160 4.8HP engine and our special HP 300 pump. This is not a dredge pump, but a high pressure unit designed specifically for pushing water higher and further, making it ideal for highbanking. We supply 15 feet of dredging hose standard. It is the longest length normally found on machines of this type, however, we have sold ours with hoses considerably longer. Our use of a power jet provides maximum suction power with less hose plugs, compared to combos that rely on suction nozzles for vacuum. Of course this combo can be equipped with an air compressor kit just like the dredge if you wish to increase your dredging productivity.

It's no surprise that the Proline 3" suction dredge/highbanker combo has seen such wide popularity with prospecting clubs, exploration companies, and miners who require a very versatile machine in a small rugged package.
