|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
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.

Keene Power Sluices
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.

5.5HP Power Sluice / 3" Dredge Combo
This is our most popular highbanker dredge combo unit. A
model 175 Power Sluice with the addition of a 3 inch dredge
suction nozzle, 10 feet of 3 inch suction hose and 12 feet
of additional pressure hose to extend the suction system.

Power Sluice Concentrator Only
This is the box and hopper assembly with legs only. You
provide the pump and hoses. Ideal for those who already
own a dredge or other equipment and want to add the concentrator
assembly. A pump with a minimum of 100gpm is required to
run the power sluice, and more horsepower will pump longer
distances. This unit can also be converted to a bank-mounted
3" dredge with optional hoses and nozzle. Part#KE173CA
Proline Highbanker / 2" Gold Dredge
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 GX50 2.1HP 4-cycle engine and
offers astounding performance in a package that
is lighter and quieter than our previous engine/pump
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.
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.
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
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!

Proline Highbanker / 2.5" Gold Dredge
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
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 Honda GX120 3.5HP 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

Proline Highbanker / 3" Gold Dredge
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
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
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.
