The power sluice, or highbanker, allows the sluice box to be placed near the material to be mined. Water is pumped from the nearest water source to feed the washing system. In very dry areas, water can also be recirculated from a settling pond back to the power sluice. This allows a miner to design a "zero-discharge" mining system where regulations do not allow discharge into a stream or river.
The hopper design washes clay and debris with a spray bar. All washed material is then classified for selective recovery. Screening off the oversized material results in better fine gold recovery.
Model 173/175
Power Sluice | Keene's power sluice can work remote placer deposits hundreds of feet away from the water source. The hopper design washes clay and debris with a high pressure washing spray bar. All washed material is then classified to minus 1/2 inch for selective recovery. The spray bar is equipped with a water valve for controlling the flow in the sluice and a garden hose port that can be used for cleaning cracks and crevices. The sluice has been improved with heavy duty latches, rolled top edges and a better hopper adjustment system. The recovery system has been enhanced with black rubber ribbed matting for quick identification of values, hungarian riffles over miners moss for fine gold recovery and expanded metal over ribbed matting for final separation. Equipped with an adjustable independent leg support system that enables the power sluice to be assembled in any type of terrain in a matter of minutes. 2.5 HP Power Sluice Concentrator

Proline Highbanker / 2" Gold Dredge Combo
| Beginners love the 2" machines because they are small, lightweight, and very affordable. The Proline 2" combo offers the versatility of being operated as either a small gold dredge or a highbanker which can be fed continuously with a small shovel. These units are mainly intended for highbanking, as they lack floats and so are more limited than a normal suction dredge in where they may be set up and operated. For best suction the power jet should be as close to the water as possible to insure easy priming and maximum suction. Our 2" combo is now powered by the all new HP 100 pump. This pump is direct coupled to the Honda 2.5 horse power 4-cycle engine and offers astounding performance in a package that is lighter and quieter than our previous engine/pump combination. There are some obvious advantages that come from using this new engine, such as the famous Honda quality, low-oil shut-off, and the ease of no longer having to worry about those gas and oil mixtures. In addition, this engine is the perfect size and operates at the proper R.P.M. to develop peak water volume and pressure, both of which are required to get full use out of this combo. | Visually, the 2" remains the same as the previous model. The refinements that were made were done to take advantage of the new pump, as well as to make it easier to operate. For example, the spray manifold which breaks up the bank run material when highbanking, has been refined to cope with the new found higher pump pressures and the highbanker hose now clamps onto the manifold in a more “relaxed” manner, eliminating many kinks in the hose. The riffle profile was altered as well, due to the increased water flow. Gold recovery was actually improved because the higher water speed gave the Hungarian riffles a greater hold on the finer gold particles. We have kept all of our other features such as our use of “Nomad” matting, the removable grizzly, and our sturdy stand with adjustable legs for uneven terrain. | Some new features include a longer pressure hose for use when dredging to allow the unit to sit further from the pump. Another feature is being able to more effectively clean out the cracks and crevices when dredging by taking advantage of our high pressure outlet, located on the side of the pump. There simply isn’t a more advanced 2" combo available anywhere! Engine 2.5HP Honda Pump HP 100 Sluice Box 10" x 36" Dredge Hose 2" x 10 ft. Highbanker Pressure Hose 1.25" x 25' Weight 57 pounds AMDS Price $1479 |
Proline Highbanker / 3" Gold Dredge Combo
| Of all the dual-purpose machines available today, our 3" 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. | This unit is powered by a Honda 5.5 horse power 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" combo has seen such wide popularity with prospecting clubs, exploration companies, and miners who require a very versatile machine in a small rugged package. Engine 5.5HP Honda Pump HP 300 Sluice Box 14" x 48" Dredge Hose 3" x 15 ft. Highbanker Pressure Hose 1.5" x 50' Weight 155 pounds Note: Air compressor in picture is an optional item.
