Ask most of the experienced dredgers, and you'll probably hear that it is the smallest dredge really capable of putting in a full day of serious dredging. The popularity of this dredge makes it a very competitive market for dredge builders, and we have worked very hard to ensure that the Proline 4" dredge stays ahead of the pack.

Extensive testing over the last two years has resulted in a more refined and efficient machine. This dredge has been equipped with a new pontoon design which has increased stability and weight capacity, while remaining compact and lightweight. The dredge frame remains the same as the previous model. It's a sturdy, bolt-together design which allows the dredge to be disassembled into smaller components for ease of transport into remote locations. Assembling the dredge requires only a few hand tools.

The dredge can be equipped with either the Honda 5.5 horse power engine and HP 350 pump (shown) or the new 6.5 horse power engine and our hot new HP 400 pump for additional power.

The new HP 400 is an extremely efficient 3" x 2" pump with a high flow, "progressive bite" five vane impeller. This is the only pump in the industry designed specifically for the 4" size dredge. We highly recommend this engine and pump combination for anyone who dredges to greater depths or at higher altitudes.

Of course, this model retains our famous "sure-flow coupler" which essentially eliminates all surface rock jams. This unique one-piece jet flair assembly not only eliminates countless hours of down time unplugging jams, but is approximately half the weight of our competitors designs, and the thick polyethylene plastic jet usually outlasts conventional steel powerjets by four to five times!

We've also kept the highly acclaimed "wave classifier" which has proven to greatly enhance fine gold recovery, while eliminating the problems associated with processing low grade black sands. The "wave classifier" develops a pulsing or jigging action which prevents the dredged materials from loading up in the front portion of the sluice box.

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. With these latest advancements, we're confident our 4" dredge will continue to be "the most popular dredge on the market!
