This allows the operator to work in deeper water with most of the advantages found in a conventional gold dredge.

Proline’s low restriction design is ideal for maintaining maximum pump performance. Unlike plastic foot valves, they do not float to the surface.

Proline foot valves are some of the best in the industry!

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, this is by far the most powerful 2.5″ combo available anywhere. The HP200 was developed for high volume as well as the working pressure necessary for successful high-banking. 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 Proline gold dredge/high-banker combos are popular with prospectors who are looking for maximum versatility in a well-built proven design. If the 2″ combo isn’t up to your needs, and if the 3″ combo is a little too large, then the 2.5″ Proline combo might be the perfect choice!

This allows the operator to work in deeper water with most of the advantages found in a conventional gold dredge.

Before its arrival most 3″ gold dredges were essentially the same size as their 4″counterparts because they used the same pontoons, frame, pump, etc. This gold dredge was designed to be smaller and lighter than our 4″ gold dredge, without sacrificing strength or stability. It sits on its own frame with pontoons that were matched to its size and weight. Another unique feature of this gold dredge is the pump. To this day, the HP300 is the only pump on the market designed specifically for 3″ gold dredges. There is no reason to pay for a big, heavy pump, when the idea is to keep the size and weight down in the first place.

This is the smallest dredge that Proline offers with our well known “sure-flow” hose coupler system. This tried and true design essentially eliminates all surface rock jams, while making it far easier to attach the dredge hose to the power jet.

In a time when some companies are now building flimsy, unstable dredges to cut manufacturing costs, and calling their creations “mini” this or “ultra” that, Proline continues to build a true 3″ dredge to provide years of trouble-free service with unmatched performance.

The two triple row spray bars ensure that all of the gravel, clay, 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 grizzly’s, it is removable to allow for easy access to the classifier and black “V” ribbed matting for inspection and/or cleanup. Also, if the combo is going to be operated solely as a gold dredge, the grizzly can be removed to save weight.

The unit is powered by a Honda GX160 engine and Proline’s powerful HP300 pump. This is a higher pressure pump designed specifically for pushing water higher and further, making it ideal for high-banking. Proline supplies 15 feet of gold dredge hose standard, however, many customers upgrade to a longer hose.

Our use of a power jet provides maximum gold dredge vacuum with fewer rock jams compared to combos that rely in the old-fashioned, cumbersome, suction nozzles. This combo can be equipped with an air compressor kit, just like our 3″ gold dredge, if you wish to increase your gold 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.

Great for when you want that extra periphreal viewing area for added safety.

This model is equipped with pontoons that have increased stability over previous models, while remaining compact and lightweight. The frame remains essentially the same as previous models. It’s a sturdy bolt together design which allows the dredge to be disassembled into smaller components for ease of transport. Assembly requires only a few hand tools.
The gold dredge is equipped with the Honda GX200 engine and HP400 pump. This gold dredge is equipped with Proline’s “sure-flow” coupler, which essentially, eliminates all surface rock jams. Proline’s unique one piece jet/flare assembly not only reduces down time caused by rock jams, is extremely light, and outlasts conventional steel jets by four to five times!
This gold dredge uses the highly acclaimed “wave classifier” which is proven to greatly enhance fine gold recovery by eliminating the problems associated with processing low grade sand. The classifier develops a pulsing, or “jigging,” action which prevents the dredged material from loading up under it. By shedding the low grade particles, the fine gold can drop out of suspension earlier and accumulate under the classifier where it is safe from the turbulence and disturbance caused by the larger rocks traveling through the sluice. The rear portion of the sluice box utilizes “Hungarian” riffles for maximum efficiency and the dredge is equipped with Nomad matting for the ultimate in fine gold recovery. No other 4″ gold dredge even comes close.

This model is aimed toward the more serious dredger and offers the most suction power of any 5″ gold dredge in its class. Powered by two Honda GX200 engines, and Proline’s proven HP400 pumps, thus making it ideal for higher altitudes or for extra deep dredging. This gold dredge is easier to refuel and start due to the location of the pumps and the two smaller, lighter power plants are easier to handle than the larger single engine/pump designs. The twin engine model is also capable of driving an additional air compressor should the need arise.

This gold dredge uses the same modular flotation and sturdy frame which bolts together for ease of transporting and storage when not in use. Naturally, this gold dredge uses the same non-clogging jetting system found on other Proline equipment.

Of course, gold recovery is the prime factor in determining the worth of any gold dredge. Proline takes pride in building equipment that delivers recovery of the finest gold. NO machine can possibly keep all the gold, but our designs have proven that they are capable of consistently recovering finer gold than those offered by our competitors. The 5″ gold dredge offers excellent recovery while remaining lightweight and simple to adjust. This gold dredge has proven to be true work horse in the field, providing years of trouble-free operation in harsh conditions.

The Proline 6″ gold dredge was designed to be strong, powerful and efficient. It looks quite similar to the 5″twin. The pontoons are larger to support the additional weight and performance of the larger unit. We use thicker plastic to ensure years of service. The framework bolts together just like the 5″ but it is a more robust design.

The 6″ is powered by two Honda GX270 engines and Proline’s powerful HP500 pump(s) for excellent suction power and minimum fuel consumption. This unit is capable of operating at considerable depths. We stock it with the PCA10 high pressure diving air compressor for deep diving.

This is also the only 6″ gold dredge on the market which has 25 feet of dredge hose as a standard length. Longer hose can be supplied if needed. This unit operates well in rugged conditions and can handle moderately swift water if secured properly. The engines can be mounted on the gold dredge frame in several locations to compensate for varying dredging and water conditions. For instance, if the gold dredge is initially set up in a stream bed with very little water running over the gravel, the dredge hose may be supported on the river bottom. After the gold dredge has been in operation for some time, the dredging hose will eventually be unsupported and the weight of the hose and the dredged material can make the machine front heavy. Moving the engines rearward can greatly help to maintain stability.

This dredge offers excellent gold recovery just like our other products, and cleanup is quick and easy for a minimum of down time. This dredge has earned a solid reputation for performance and dependability. These commercial quality machines are currently being operated with great results in North America, South America, Africa, and throughout the Pacific.

OUTSTANDING DREDGE VACUUM AND LONG LIFE

Proline manufactures one of the most comprehensive series of pumps in the small dredge industry today. These are high performance centrifugal pumps designed specifically for operating our dredges and dual-purpose machines. First, they are cast in the US from high quality aluminum then heat treated to a “T-6” hardness for years of service. Each part is then machined on computer controlled equipment to maintain the exact tolerances required for optimum performance. Proline pumps are 5-vane and 6-vane “aggressive bite” impellers with large intake throats to provide high volume with working pressure greater than normally found on pumps of this type. They are hand-assembled using US made seals and grade 8 hardware. The quality and performance of these units, when coupled with Proline’s efficient jetting systems, offers outstanding dredge vacuum, very little required service, and long life.
